Abstract: This paper introduces AsymmeTrix, a novel approach to vector search and embeddings that leverages asymmetric cosine similarity to model directional relationships between data points. We demonstrate the significance of this approach by highlighting the limitations of existing symmetric solutions and comparing it to alternate approaches for addressing the problem. Our proposed method has applications in various domains where asymmetric relationships are essential, such as job matching, recommendation systems, and knowledge graph completion.

Introduction

Vector embeddings, which represent objects as points in a continuous vector space, have emerged as a powerful tool in natural language processing, recommendation systems, and other machine learning applications. These embeddings typically rely on symmetric similarity measures, such as cosine similarity, to compare objects in the vector space. However, symmetric similarity measures may not accurately capture the asymmetric relationships that exist between objects in many real-world scenarios. In this paper, we propose AsymmeTrix, a new approach to vector search and embeddings that incorporates asymmetric cosine similarity to model the directionality of relationships between data points.

Limitations with Existing Symmetric Solutions

Traditional vector embeddings use symmetric similarity measures, such as cosine similarity, to quantify the relatedness between objects. While these measures can effectively capture similarity in many cases, they fail to model the inherently asymmetric relationships between objects in certain domains. For instance, consider the problem of job matching, where job postings and job applicants have different feature spaces and asymmetric relationships. In such cases, symmetric similarity measures may not provide accurate representations of the underlying relationships, leading to suboptimal search results and recommendations.

AsymmeTrix: Asymmetric Vector Embeddings

AsymmeTrix is a novel approach to vector embeddings that uses asymmetric cosine similarity to model the directionality of relationships between data points. By introducing a weighting factor based on a domain-specific asymmetric weighting function, AsymmeTrix is able to capture the inherent directionality of relationships between objects in various application domains. The weighting function can be tailored to the specific use case, allowing for greater flexibility and adaptability.

Significance of the AsymmeTrix Approach

The AsymmeTrix approach offers several advantages over traditional symmetric similarity measures:

Directionality: AsymmeTrix is designed to capture asymmetric relationships between objects, providing a more accurate representation of the underlying data structure in domains where directionality is essential.
Flexibility: The asymmetric weighting function in AsymmeTrix can be easily customized to different application domains, allowing the approach to be adapted to a wide range of use cases.
Improved search results and recommendations: By modeling asymmetric relationships, AsymmeTrix can lead to more accurate search results and recommendations in domains where directionality is important, such as job matching, recommendation systems, and knowledge graph completion.

Alternate Approaches

There are several alternate approaches to address the limitations of symmetric similarity measures:

Graph-based structures combined with vector embeddings: This hybrid approach leverages graph-based structures to capture complex relationships and continuous vector spaces to represent objects in a continuous space. While this approach can model complex relationships effectively, it can be computationally expensive and challenging to implement.
Asymmetric kernel functions in vector space: Asymmetric kernel functions modify standard kernel functions or design custom functions to model asymmetric relationships. This approach offers a balance between ease of implementation, scalability, and insight generation, but may require more effort to implement than asymmetric cosine similarity.

Conclusion

n this paper, we presented AsymmeTrix, a novel approach to vector search and embeddings that leverages asymmetric cosine similarity to model directional relationships between data points. We demonstrated the significance of this approach by highlighting the limitations of existing symmetric solutions and comparing it to alternate approaches for addressing the problem. AsymmeTrix offers directionality, flexibility, and improved search results and recommendations, making it well-suited for a wide range of applications, such as job matching, recommendation systems, and knowledge graph completion. By modeling asymmetric relationships, AsymmeTrix can provide more accurate and meaningful insights in domains where directionality is essential, opening up new possibilities for research and real-world applications.

APPENDIX: Full ChatGPT Discussion

Below is the full ChatGPT Discussion that generated the code, paper, and Twitter thread.

I have an idea I’d like to explore around improving the current state of vector search, or embeddings. Before I throw out my idea, can you quickly confirm if you know what I’m referring to?

Yes, I’m familiar with vector search and embeddings. In the context of machine learning and natural language processing, embeddings are a way to represent words, phrases, or other types of data as continuous vectors in a high-dimensional space. These vector representations, or embeddings, can capture semantic and syntactic relationships between the data points. Vector search, also known as similarity search, involves finding similar vectors in the embedding space based on a specific distance metric, such as cosine similarity or Euclidean distance. This is useful for tasks like information retrieval, document classification, or recommendation systems. Please feel free to share your idea, and I’ll be glad to provide feedback or answer any questions you may have.

Yes, you get it. Here’s my thought. With vector search or embeddings, it does a great job of understanding similarity between phrases or ideas. Though as I think about how the human brain works, the way in which two objects are related isn’t necessarily identical both ways. The relationship between two ideas in a person’s mind is not equal in each direction. Do you see where I’m going with this?

Yes, I see where you’re going with this. You’re suggesting that the relationship between two concepts might not be symmetric, as it is with the distance measures typically used in vector search. In other words, the similarity between concept A and concept B might not be the same as the similarity between concept B and concept A, in a human’s mind.

This is an interesting idea, and it might be worth exploring different techniques or models that can better capture these asymmetric relationships. One possible approach could be using directed graphs or other structured representations to model the relationships between concepts, rather than relying solely on continuous vector spaces. This would allow you to model asymmetric relationships more explicitly, and potentially lead to more nuanced and accurate representations of human-like associations between ideas.

Currently with embeddings, there is the idea of leveraging metadata for filtering. I’d love to design a new system for embedding retrieval or vector embeddings that takes into account the asymmetric relationship between two objects. This could be a causation type relationship (eg. if an earth quake happens, many buildings get destroyed – though many buildings getting destroyed does not result in an earth quake). It should also take into account sub category, type relationships (eg. boss and employee, parent and child, mammal and elephant). Please design and describe a solution for this in detail, including best way to set this up to be highly scalable, efficient, and cost effective. If there are multiple approaches, present them, the pros and cons, and steps on how to decide on the best approach.

To design a system that captures asymmetric relationships, causation, and hierarchical relationships, we can consider a combination of techniques. Here are three potential approaches:

Graph-based approach with knowledge graphs:

Create a knowledge graph that captures relationships between entities in a directed manner, allowing for asymmetric relationships.
Enrich the graph with metadata and hierarchical information, such as categories, types, and causality.
For scalability, use distributed graph databases (e.g., JanusGraph, Dgraph, or Neo4j) to store and query the graph efficiently.

Pros:

Captures asymmetric relationships and complex structures.
Can store and retrieve complex relationships efficiently.

Cons:

Might require significant effort to construct and maintain the knowledge graph.
Difficult to incorporate continuous vector spaces directly.

Hybrid approach: Combining graph-based structures with vector embeddings:

Use a graph-based structure to capture asymmetric relationships and hierarchy.
Train embeddings on the graph structure, incorporating asymmetric relationships (e.g., using graph neural networks or GraphSAGE).
Use a combination of graph-based retrieval and similarity search in the embedding space for retrieval.

Pros:

Combines the benefits of both graph-based structures and vector embeddings.
Can represent complex relationships and continuous vector spaces.

Cons:

Requires more complex models and infrastructure.
Might be less efficient than using either graphs or embeddings alone.

Asymmetric similarity measures in vector space:

Explore asymmetric similarity measures (e.g., asymmetric cosine similarity, asymmetric kernel functions) that can be applied directly in the vector space.
Train embeddings with these asymmetric measures or adapt existing embeddings.
Apply asymmetric similarity measures during retrieval to account for asymmetric relationships.

Pros:

Can be directly applied to existing vector embeddings.
Relatively easy to implement.

Cons:

Might not capture complex relationships as effectively as graph-based approaches.
Requires tuning and experimentation to find suitable asymmetric similarity measures.

To choose the best approach, consider the following steps:

Analyze the specific requirements of your application, such as the importance of capturing asymmetric relationships, hierarchy, and causality.
Evaluate the complexity of the relationships and the scalability requirements.
Consider the available resources, including infrastructure and computational power.
Conduct experiments and compare the performance of each approach based on your specific use case and requirements.

Ultimately, the choice depends on your specific use case and priorities, such as the importance of capturing complex relationships, computational efficiency, and the ease of implementation.

I’d like to consider options 2 and 3. I don’t understand how asymmetric cosine similarity and asymmetric kernel functions work. Can you explain them a bit more? I understand that typical cosine similarity will result in a single number representing similarity.

Asymmetric cosine similarity and asymmetric kernel functions are variants of similarity measures that account for the directionality of relationships between data points. While these measures are not as common as their symmetric counterparts, they can be used to better model asymmetric relationships in certain situations.

Asymmetric cosine similarity:

In the standard cosine similarity measure, you calculate the cosine of the angle between two vectors, which results in a symmetric similarity score between 0 and 1. Asymmetric cosine similarity, on the other hand, introduces a weighting factor to account for the directionality of the relationship. For instance, if we have two vectors A and B, we can calculate asymmetric cosine similarity as follows:

AsymmetricCosine(A, B) = Cosine(A, B) * Weight(A, B)

Here, the weight function, Weight(A, B), can be defined based on your specific application or requirements. This weighting function should capture the directionality of the relationship between A and B.

Asymmetric kernel functions:

Kernel functions are used to measure similarity between data points in a transformed feature space. Commonly used kernel functions, such as the Gaussian (RBF) kernel, are symmetric. However, you can create asymmetric kernel functions by modifying the standard kernel functions or designing custom functions to capture the directionality of relationships.

For instance, if we have a Gaussian kernel function K(x, y) = exp(-||x – y||^2 / (2 * σ^2)), we can introduce an asymmetric factor based on the directionality of the relationship between x and y:

AsymmetricGaussian(x, y) = K(x, y) * AsymmetricFactor(x, y)

Here, the AsymmetricFactor(x, y) function can be defined based on your specific application or requirements. Similar to the asymmetric cosine similarity, this function should capture the directionality of the relationship between x and y.

In both cases, the asymmetric similarity measures result in a single number representing the similarity, just like their symmetric counterparts. However, the asymmetric measures incorporate directionality into the similarity calculation, allowing for more nuanced modeling of relationships between data points.

Okay, so let’s analyze the three options: graph+vector, asymmetric cosine, and asymmetric kernel. Our goal is to build a business, so we need to take into account cloud and computational costs, scalability, etc. Provide an analysis on which approach makes the most sense to build.

When considering the three options for building a business, it’s essential to analyze each approach in terms of computational costs, scalability, ease of implementation, and potential for generating valuable insights. Here’s a comparison of the three approaches:

Graph-based structures combined with vector embeddings (Hybrid approach):

Computational costs: This approach requires training embeddings on the graph structure (e.g., using graph neural networks or GraphSAGE) and combining graph-based retrieval with similarity search in the embedding space. These models can be computationally expensive to train, and the retrieval process may be slower compared to using embeddings alone.
Scalability: Distributed graph databases can be used to store and query the graph efficiently, ensuring that the system scales well. However, the combination of graph-based retrieval and similarity search in the embedding space may require significant computational resources and efficient indexing techniques.
Ease of implementation: This approach is relatively complex, as it combines the benefits of both graph-based structures and vector embeddings. Implementing and maintaining both parts of the system can be challenging.
Insights generation: This approach can capture complex relationships and continuous vector spaces, making it more likely to generate valuable insights and provide accurate results.

Asymmetric cosine similarity in vector space:

Computational costs: Asymmetric cosine similarity introduces a weighting factor to the standard cosine similarity measure, which has minimal computational overhead. The overall computational cost of this approach is likely lower than the hybrid approach.
Scalability: Since this approach can be applied directly to existing vector embeddings, it should scale well with traditional similarity search techniques and efficient indexing methods, such as approximate nearest neighbor (ANN) search.
Ease of implementation: Asymmetric cosine similarity is relatively easy to implement, as it only requires modifying the standard cosine similarity measure by introducing a weighting factor.
Insights generation: Asymmetric cosine similarity may not capture complex relationships as effectively as graph-based approaches, but it can provide more nuanced similarity measures than symmetric cosine similarity.

Asymmetric kernel functions in vector space:

Computational costs: Asymmetric kernel functions require modifying standard kernel functions or designing custom functions. The computational cost depends on the specific kernel function used and can vary significantly.
Scalability: Like asymmetric cosine similarity, this approach can be applied directly to existing vector embeddings, which should scale well with traditional similarity search techniques and efficient indexing methods, such as ANN search.
Ease of implementation: Asymmetric kernel functions may require more effort to implement than asymmetric cosine similarity, as they involve creating custom kernel functions or modifying existing ones.
Insights generation: Asymmetric kernel functions can potentially model asymmetric relationships more effectively than symmetric kernel functions, but they may not capture complex relationships as well as graph-based approaches.

To decide which approach to build, consider the following factors:

Prioritize computational costs: If minimizing computational costs is the primary concern, asymmetric cosine similarity is likely the most cost-effective solution.
Prioritize scalability: Both asymmetric cosine similarity and asymmetric kernel functions should scale well using traditional similarity search techniques and efficient indexing methods. The hybrid approach can also scale well but may require more resources.
Prioritize ease of implementation: Asymmetric cosine similarity is the easiest approach to implement, followed by asymmetric kernel functions. The hybrid approach is the most complex to implement and maintain.
Prioritize insights generation: The hybrid approach is more likely to generate valuable insights and provide accurate results due to its ability to capture complex relationships and continuous vector spaces.

In conclusion, if computational costs and ease of implementation are top priorities, asymmetric cosine similarity might be the best approach. If generating valuable insights and accurately capturing complex relationships are more important, the hybrid approach could be the most suitable choice, provided that you can handle its complexity and potential scalability challenges. Asymmetric kernel functions can serve as an intermediate option that balances ease of implementation, scalability, and insights generation.

Let’s go with asymmetric cosine similarity. Please create a minimalist python script to demo this.

Here’s a minimalist Python script to demonstrate asymmetric cosine similarity. In this example, we define a simple asymmetric weighting function based on the sum of the elements in each vector. You can replace this weighting function with one that is more appropriate for your specific use case.

pythonCopy codeimport numpy as np

def asymmetric_cosine_similarity(vector_a, vector_b):
    # Calculate the cosine similarity
    dot_product = np.dot(vector_a, vector_b)
    magnitude_a = np.linalg.norm(vector_a)
    magnitude_b = np.linalg.norm(vector_b)
    cosine_similarity = dot_product / (magnitude_a * magnitude_b)
    
    # Define an asymmetric weighting function
    weight_a = np.sum(vector_a)
    weight_b = np.sum(vector_b)
    asymmetric_weight = weight_a / weight_b
    
    # Calculate asymmetric cosine similarity
    asymmetric_similarity = cosine_similarity * asymmetric_weight
    return asymmetric_similarity

# Example vectors
vector_a = np.array([1, 2, 3])
vector_b = np.array([1, 1, 4])

# Compute asymmetric cosine similarity
similarity = asymmetric_cosine_similarity(vector_a, vector_b)
print("Asymmetric cosine similarity:", similarity)

This script defines an asymmetric_cosine_similarity function that calculates the cosine similarity between two input vectors and then applies an asymmetric weighting function. The example vectors vector_a and vector_b are used to demonstrate the calculation of asymmetric cosine similarity.

Please note that this is just a simple example, and you should replace the asymmetric weighting function with one that is tailored to your specific use case and captures the directionality of the relationships between your data points.

Can you come up with an example use case where this would be more helpful than symmetric cosine similarity and write a python script that demonstrates this?

Consider a use case where we have two sets of items, with each item represented by a feature vector. In this scenario, we want to measure the similarity between items from different sets, but the relationships are asymmetric. For instance, let’s say Set A represents job postings and Set B represents job applicants. We want to find the best match between job postings and applicants, but the similarity from a job posting to an applicant may not be the same as from an applicant to the job posting.

In this example, we’ll use asymmetric cosine similarity to capture the directionality of the relationships between job postings and job applicants. We will define a simple weighting function that gives higher importance to matches where the applicant has more skills than required by the job posting.

pythonCopy codeimport numpy as np

def asymmetric_cosine_similarity(job_posting, applicant):
    # Calculate the cosine similarity
    dot_product = np.dot(job_posting, applicant)
    magnitude_posting = np.linalg.norm(job_posting)
    magnitude_applicant = np.linalg.norm(applicant)
    cosine_similarity = dot_product / (magnitude_posting * magnitude_applicant)
    
    # Define an asymmetric weighting function
    skills_posting = np.sum(job_posting)
    skills_applicant = np.sum(applicant)
    asymmetric_weight = skills_applicant / skills_posting
    
    # Calculate asymmetric cosine similarity
    asymmetric_similarity = cosine_similarity * asymmetric_weight
    return asymmetric_similarity

# Example job postings and applicants represented by feature vectors
job_posting_1 = np.array([1, 0, 1])  # Requires skill A and skill C
job_posting_2 = np.array([0, 1, 1])  # Requires skill B and skill C

applicant_1 = np.array([1, 0, 1])  # Has skill A and skill C
applicant_2 = np.array([1, 1, 1])  # Has skill A, skill B, and skill C

# Compute asymmetric cosine similarity between job postings and applicants
similarity_1_1 = asymmetric_cosine_similarity(job_posting_1, applicant_1)
similarity_1_2 = asymmetric_cosine_similarity(job_posting_1, applicant_2)
similarity_2_1 = asymmetric_cosine_similarity(job_posting_2, applicant_1)
similarity_2_2 = asymmetric_cosine_similarity(job_posting_2, applicant_2)

print("Asymmetric cosine similarity between job postings and applicants:")
print("Job posting 1 and applicant 1:", similarity_1_1)
print("Job posting 1 and applicant 2:", similarity_1_2)
print("Job posting 2 and applicant 1:", similarity_2_1)
print("Job posting 2 and applicant 2:", similarity_2_2)

In this script, the asymmetric_cosine_similarity function calculates the similarity between a job posting and an applicant by considering both the cosine similarity and the asymmetric weight based on the number of skills. The output demonstrates how the asymmetric cosine similarity can provide different similarity scores depending on the direction of the relationship between the job postings and applicants. This example demonstrates that asymmetric cosine similarity can be more helpful than symmetric cosine similarity in cases where the relationships between items are inherently directional.

This is great, but repetitive. Can you rewrite and optimize so it can scale number of job postings and applicants without adding new lines of code?

Sure! Here’s an optimized version of the script using loops to handle any number of job postings and applicants:

pythonCopy codeimport numpy as np

def asymmetric_cosine_similarity(job_posting, applicant):
    dot_product = np.dot(job_posting, applicant)
    magnitude_posting = np.linalg.norm(job_posting)
    magnitude_applicant = np.linalg.norm(applicant)
    cosine_similarity = dot_product / (magnitude_posting * magnitude_applicant)
    
    skills_posting = np.sum(job_posting)
    skills_applicant = np.sum(applicant)
    asymmetric_weight = skills_applicant / skills_posting
    
    asymmetric_similarity = cosine_similarity * asymmetric_weight
    return asymmetric_similarity

# Example job postings and applicants represented by feature vectors
job_postings = [
    np.array([1, 0, 1]),  # Job posting 1: Requires skill A and skill C
    np.array([0, 1, 1])   # Job posting 2: Requires skill B and skill C
]

applicants = [
    np.array([1, 0, 1]),  # Applicant 1: Has skill A and skill C
    np.array([1, 1, 1])   # Applicant 2: Has skill A, skill B, and skill C
]

# Compute asymmetric cosine similarity between job postings and applicants
similarity_matrix = np.zeros((len(job_postings), len(applicants)))

for i, job_posting in enumerate(job_postings):
    for j, applicant in enumerate(applicants):
        similarity = asymmetric_cosine_similarity(job_posting, applicant)
        similarity_matrix[i, j] = similarity

print("Asymmetric cosine similarity between job postings and applicants:")
print(similarity_matrix)

In this optimized version, we store job postings and applicants in lists and use loops to compute the asymmetric cosine similarity between all pairs of job postings and applicants. The results are stored in a similarity matrix, which can be easily expanded to handle any number of job postings and applicants without adding new lines of code.

This is great, but can you rewrite this so more details are printed about each match?

Certainly! Here’s a version of the script that prints more details about each match:

pythonCopy codeimport numpy as np

def asymmetric_cosine_similarity(job_posting, applicant):
    dot_product = np.dot(job_posting, applicant)
    magnitude_posting = np.linalg.norm(job_posting)
    magnitude_applicant = np.linalg.norm(applicant)
    cosine_similarity = dot_product / (magnitude_posting * magnitude_applicant)
    
    skills_posting = np.sum(job_posting)
    skills_applicant = np.sum(applicant)
    asymmetric_weight = skills_applicant / skills_posting
    
    asymmetric_similarity = cosine_similarity * asymmetric_weight
    return asymmetric_similarity

# Example job postings and applicants represented by feature vectors
job_postings = [
    np.array([1, 0, 1]),  # Job posting 1: Requires skill A and skill C
    np.array([0, 1, 1])   # Job posting 2: Requires skill B and skill C
]

applicants = [
    np.array([1, 0, 1]),  # Applicant 1: Has skill A and skill C
    np.array([1, 1, 1])   # Applicant 2: Has skill A, skill B, and skill C
]

# Compute asymmetric cosine similarity between job postings and applicants
for i, job_posting in enumerate(job_postings):
    for j, applicant in enumerate(applicants):
        similarity = asymmetric_cosine_similarity(job_posting, applicant)
        print(f"Job posting {i + 1} and applicant {j + 1}:")
        print(f"  - Job posting: {job_posting}")
        print(f"  - Applicant: {applicant}")
        print(f"  - Asymmetric cosine similarity: {similarity:.4f}")
        print()

This version of the script prints additional information about each match, including the feature vectors of the job postings and applicants, and the asymmetric cosine similarity with 4 decimal places. The results are displayed in a more readable format, making it easier to understand the details of each match.

Please write a comprehensive academic AI paper about this new approach to vector search/embeddings. Come up with a fun nickname for the approach. Provide limitations with existing symmetric solutions, the significance of this new approach, and alternate approaches to the problem.

Significance of the AsymmeTrix Approach

The AsymmeTrix approach offers several advantages over traditional symmetric similarity measures:

Directionality: AsymmeTrix is designed to capture asymmetric relationships between objects, providing a more accurate representation of the underlying data structure in domains where directionality is essential.
Flexibility: The asymmetric weighting function in AsymmeTrix can be easily customized to different application domains, allowing the approach to be adapted to a wide range of use cases.
Improved search results and recommendations: By modeling asymmetric relationships, AsymmeTrix can lead to more accurate search results and recommendations in domains where directionality is important, such as job matching, recommendation systems, and knowledge graph completion.

Alternate Approaches

There are several alternate approaches to address the limitations of symmetric similarity measures:

Graph-based structures combined with vector embeddings: This hybrid approach leverages graph-based structures to capture complex relationships and continuous vector spaces to represent objects in a continuous space. While this approach can model complex relationships effectively, it can be computationally expensive and challenging to implement.
Asymmetric kernel functions in vector space: Asymmetric kernel functions modify standard kernel functions or design custom functions to model asymmetric relationships. This approach offers a balance between ease of implementation, scalability, and insight generation, but may require more effort to implement than asymmetric cosine similarity.
