Avoid Shortcut Learning: Behavioral Signals in LLM Rerankers
1+ hour, 53+ min ago (418+ words) Raw click stats are a powerful, production-friendly signal for LLM rerankers — but they can also make those rerankers lazy. Injecting CTR/QSS/Q-values into prompts yields big wins on head queries, yet models will often learn the shortcut "follow the…...
AI 'wins a medal' at the Mathematical Olympiad and the challenge of Vietnam's technology workforce.
4+ hour, 42+ min ago (762+ words) An AI was declared to have won a gold medal at the International Mathematical Olympiad, but in reality, it wasn't a competition between a human and a machine. This story raises questions about the standards for evaluating AI and highlights…...
How to Scrape Data from Multiple Web Pages
5+ day, 7+ hour ago (1513+ words) Scraping a single page is simple. The moment you need data from dozens, hundreds, or thousands of pages – a paginated product catalog, a series of blog posts, or a list of URLs from a spreadsheet – the complexity increases fast. Loops…...
My prompt-injection fix caught 0 of 20 attacks. The part I almost didn't build caught all of them.
2+ hour, 9+ min ago (483+ words) I built a checker for AI-drafted answers to retirement questions (retirement-answer-check). Before a customer sees a draft, it decides SEND or REVIEW. Plain code checks every number against an IRS-sourced facts table. Two model "judges" handle what code can't read:…...
