Published:

Understanding why deep learning models make certain predictions has become just as important as achieving high accuracy. As Computer Vision systems continue to influence decisions in healthcare, autonomous driving, security, and edge AI, the demand for transparency has never been greater. Yet, modern architectures like ResNet18—designed for depth, abstraction, and performance—often operate as opaque black boxes.

How to Make a Sketchpad for ML Projects in Gradio?

less than 1 minute read

Published:

Interactive tools are invaluable in machine learning (ML) projects, especially when demonstrating model capabilities and gathering feedback. A sketchpad is an excellent example of such a tool, allowing users to draw and interact with models in real time. Gradio, an open-source library for building user interfaces for machine learning models, simplifies the creation of such tools.
