From Vectors to Volatility: How AI Actually Applies to Trading (Not Magic, Just Math)

2 months ago 高效码农

From First Principles: From AI’s Underlying Logic to AI Trading I. The Underlying Logic of Large Models Before delving into AI trading, it’s essential to clarify the computational essence of large models. Many people treat large language models (LLMs) as black boxes, assuming they “understand” language and can “think” through problems. In reality, when dissected, they operate on a set of vector operations. Core Idea: Represent Everything with Vectors Humans use words and grammar to convey meaning. Machines, however, only recognize numbers. The first step for large models is to map discrete tokens (which can be words or subwords) to …

Context Engineering: Why Limiting AI Memory Makes It Smarter (The Agent Bottleneck)

2 months ago 高效码农

The Paradox of Intelligence: Why Limiting an AI’s “Memory” Makes It Smarter In the 1990s, neuroscientist Antonio Damasio studied a perplexing patient. The man, named Elliot, had undergone surgery to remove a brain tumor, which accidentally damaged a small region of his prefrontal cortex. Post-surgery, his IQ scores were normal, his logical reasoning was sharp, and his memory was intact—all cognitive metrics were flawless. Yet, his life fell apart. He lost the ability to make decisions. Not because he couldn’t analyze, but because he analyzed too much. Choosing what to eat for lunch could involve a thirty-minute, detailed comparison of …
