Model Explorer is a machine learning model visualization tool developed by Google. It specializes in visualizing large graphs in an intuitive hierarchical format, and it's also suitable for smaller models. This tool is particularly helpful in simplifying the deployment process of large models on edge platforms by visualizing the conversion, quantization, and optimization of data. Model Explorer leverages graphic technologies used in 3D gaming and animation production, such as instanciation rendering and multi-channel signed distance fields (MSDF), and adapts them for machine learning graph rendering. It supports various graph formats, including those used by JAX, PyTorch, TensorFlow, and TensorFlow Lite. Model Explorer makes large models easier to understand through its hierarchical views and ability to navigate complex structures.
