The Learning Interpretability Tool: Interactively analyze ML models to understand their behavior in an extensible and framework agnostic interface.
Role in this project:Front-end Developer
Front-end DeveloperContributions:8 commits in 3 months
Contributions summary:Jian-syuan primarily focused on enhancing the user interface and interactive elements of the LIT (Learning Interpretability Tool). Their work included integrating a color legend component and incorporating it into existing modules such as the embeddings projector, sequence salience, and salience map module. They also added a slider for adjusting gamma values within the salience map module to allow users to adjust the color mapping. Further, they improved the color legend element to display a range of values upon hovering over the color blocks within the sequential values.
