I used to spent few time tracing back these formulas every time someone mentioned them in a paper. This is the post I wish I had on day one. The Four Things That Can Happen Forget formulas for a sec

I was recently reading through the literature on alternative machine learning architectures. Specifically, I was looking at the shift away from standard back-propagation toward a biologically plausibl

In the AI world of 2026, we have been sold a specific dream: Shred your PDF, turn the chunks into numbers (vectors), and let math find the answer. This is Vector RAG, and for simple FAQ bots, it works
