What Are Embeddings? How AI Represents Meaning as Numbers
2+ week, 23+ min ago (1027+ words) Embeddings are dense numerical vectors learned so that items with useful semantic or behavioral relationships occupy nearby regions of a representation space. This guide explains the mechanism, trade-offs, evaluation, and controls that matter in practice. Embeddings deserves a precise explanation…...
RNN vs LSTM vs GRU for Sequential Data
3+ hour, 10+ min ago (460+ words) A simple guide to understanding RNN, LSTM, and GRU, how they work, their differences, and where to use them. Sequential data is data where the order of …...
Vectors: How Numbers Turns Meaning Into Direction
5+ hour, 49+ min ago (1288+ words) When we say -’ The boy is playing in the garden.’ we see words. Now a language model can only interpret numbers. Before an AI system can compare …...
New AI Framework Turns Thousands of Product Reviews Into Balanced,
8+ hour, 11+ min ago (55+ words) Online shoppers scrolling through a popular product on a major e-commerce platform may face thousands of customer reviews, each expressing a slightly different opinion about quality, price, delivery, durability, or customer service. Reading them all is impossible, and the automated…...
I described 1,245 tables with an LLM and retrieval got worse
12+ hour, 50+ min ago (1126+ words) The cataloguing step is supposed to be the easy win. You have a schema whose tables are called ecm_template_link and v_pmpm, your users ask questions in English, and the gap between those two vocabularies is why retrieval misses. So you point a…...
BPE-Style Tokenizers: The Small Algorithm That Decides What an LLM Can See
17+ hour, 14+ min ago (1289+ words) Hello, I'm Shrijith Venkatramana, and I'm building LiveReview — a blast-radius aware AI code review... Tagged with ai, webdev, programming, productivity....
Spherical Topic Models Bring Coherence to Short-Text Machine Learning
13+ hour, 21+ min ago (55+ words) Probabilistic topic models have long served as one of the workhorses of text mining, offering a statistical lens through which vast collections of documents can be organized into interpretable themes. From latent Dirichlet allocation onward, these models have assumed that…...
Day 7: Dot Product & Cosine Similarity, and How Machines Measure Similarity
13+ hour, 18+ min ago (47+ words) Part 7 of a 50-day journey from zero to building AI agents. Picking up from yesterday Yesterday we treated vectors as just …...
Tokenization Is Not a Preprocessing Step. It’s a System Design Decision.
17+ hour, 50+ min ago (281+ words) Introduction At some point almost every LLM engineer hits one of these: A “128k context window” model runs out of …...
Day 16: Cosine Similarity and Semantic Search Basics
1+ day, 2+ hour ago (495+ words) Cosine similarity measures how closely two vectors point in the same direction, regardless of their length. Picture a vector as an arrow from the origin in space. Cosine similarity looks at the angle between two such arrows. If they point…...
