Problem Description

The project contains function block explanations in the Sphinx comment format, but the Sphinx documentation has not been generated yet. Without proper documentation, it can be challenging for users to understand the functionality of the codebase and how to use the provided functions effectively.

Expected Behavior

Generating Sphinx documentation will provide clear and comprehensive documentation for the project, enabling users to understand the purpose of each function, its parameters, and return values. This documentation will serve as a valuable resource for developers and users alike, facilitating easier integration and usage of the codebase.

Proposed Solution

To generate Sphinx documentation for the project:

1. Install Sphinx and necessary dependencies if not already installed.
2. Configure Sphinx settings and directories to point to the relevant codebase.
3. Run the Sphinx documentation generation command to parse the codebase and generate HTML or other documentation formats.
4. Review and refine the generated documentation as needed to ensure clarity and completeness.
5. Publish the documentation on a suitable platform or include it within the project repository for easy access.
6. As the project will primarily be hosted via gh-pages, ensure that the generated documentation exists as a separate branch (e.g., gh-pages branch) for easy deployment and accessibility.

Impact

• Severity: Medium
• Priority: High

Generating Sphinx documentation is crucial for enhancing the usability and maintainability of the project. Clear documentation will streamline the onboarding process for new contributors and users, improving the overall accessibility and adoption of the project.

Problem Description

Currently, the final output displays graphs generated via st.pyplot within a loop for each generation. However, the output lacks clarity as there is no clear separation between the graphs and their corresponding accuracy and F1 score for each iteration. Additionally, the user needs to scroll through the code explanation to reach the output section, which can be inconvenient.

Expected Behavior

To improve user experience and output clarity, the following enhancements are proposed:

1. Each graph generated via iteration should be accompanied by its corresponding accuracy and F1 score, with a clear separator to distinguish between iterations.
2. Consider generating the final output in a separate webpage altogether, providing a more organized and user-friendly interface.
3. Instead of displaying the standard Streamlit "running" indicator, consider implementing a splash screen or loading animation to indicate progress during graph generation.

Proposed Solution

To address these issues, the final code can be modified to include:

• A clear separator (e.g., st.markdown('---')) between each graph and its corresponding accuracy and F1 score.
• Utilizing Streamlit's st.spinner or custom loading animation components to indicate progress during graph generation.
• Investigating options to generate the final output in a separate webpage or section for improved organization and navigation.

Impact

• Severity: Medium
• Priority: High

Implementing these enhancements will significantly improve the clarity and usability of the final output, making it easier for users to interpret and analyze the results of the algorithm. These changes will enhance the overall user experience and satisfaction with the application.

Problem Description

The project utilizes Particle Swarm Optimization (PSO) to optimize neural network classifiers. While PSO offers a novel approach to optimizing neural network parameters, it's essential to assess its effectiveness compared to traditional methods commonly used for improving neural network classifiers.

Expected Behavior

Comparing PSO-based optimization with traditional methods will provide valuable insights into the efficacy and efficiency of PSO in optimizing neural network classifiers. The comparison can be based on various factors, including but not limited to:

• Accuracy: Compare the accuracy achieved by PSO-optimized neural networks with those optimized using traditional methods.
• F1 Score: Evaluate the F1 score obtained by PSO-optimized classifiers against traditional methods.
• Convergence Rate: Assess the convergence rate of PSO-based optimization compared to traditional optimization techniques.
• Scalability: Evaluate the scalability of PSO for optimizing neural networks concerning the size and complexity of datasets.
• Robustness: Determine the robustness of PSO-optimized classifiers in handling noisy or unbalanced datasets compared to traditional methods.

Proposed Solution

The insights gained from the comparison will inform future optimization strategies and guide decision-making in selecting the most suitable approach for specific use cases.

Problem Description

When running the final file, the markdown content from the imported files is being displayed along with the final plots at the end of the execution. This results in unnecessary clutter and duplication of information in the output.

Expected Behavior

The final output should only display the final plots along with relevant information such as accuracy and F1 score. The markdown content from the imported files should be eliminated from the output.

Proposed Solution

To address this issue, we need to modify the final file or the way markdown content is imported and displayed. This could involve:

1. Adjusting the import statements to only import functions/classes without displaying markdown content.
2. Refactoring the final file to prevent the display of markdown content during execution.
3. Utilizing Streamlit's capabilities to control the display of markdown content more effectively.

Impact

• Severity: Low
• Priority: Medium

This issue impacts the readability and clarity of the final output but does not affect the functionality of the code. Resolving this issue will enhance the user experience and make the output more concise and focused.

Description

This repository addresses the integration of multiple functionalities within the K-Nearest Neighbors (KNN) algorithm to enhance its classification capabilities. KNN is a widely used non-parametric method for classification and regression tasks, but its performance can be further improved by incorporating various techniques and modifications.

This includes explanations of concepts such as similarity matrix computation, nearest neighbors retrieval, and fitness evaluation using equation 6 from the referenced paper.

4. Document K-means Evaluation: The kmeans_eval method should be documented to explain its role in evaluating fitness using K-means clustering. Users would benefit from understanding how this evaluation method differs from the standard fitness calculation.

5. Include Vel Class Documentation: Similarly, the Vel class needs proper documentation to explain its purpose and functionality within the PSO algorithm. This includes descriptions of its attributes and any methods it contains.

Expected Outcome:

• Improved understanding of the PSO algorithm's implementation within the codebase.
