CPU Caches and Cache Coherence: The Memory Hierarchy That Makes Modern Computing Fast
00:00A comprehensive exploration of how CPU caches bridge the processor-memory speed gap. Learn about cache architecture, replacement policies, coherence protocols, and how to write cache-friendly code for maximum performance.
Information Geometry: Statistical Manifolds, the Fisher Information Metric, and Natural Gradient Descent
A rigorous journey through information geometry—the Riemannian geometry of statistical models, the Fisher metric as the unique invariant metric, natural gradient, and the dually flat structure of exponential families.
