New tool for visualizing embeddings of ChatGPT Q&A
In plain words
This tool visualizes embeddings from ChatGPT question-and-answer interactions in an interactive format. It enables users to explore how the AI model represents and relates different conversational exchanges spatially. The visualization helps researchers, developers, and curious users understand the underlying structure of ChatGPT's responses by displaying semantic relationships between questions and answers.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
