Cosy Moments • 25 implied HN points • 08 Oct 24
📖 Philosophy History Ethics Religion Enlightenment Political Thought
  1. John Locke, often seen as a key Enlightenment thinker, has many writings that show inconsistencies and outdated ideas, just like religious texts. This means we should question how much we really rely on his thoughts today.

Does GPT-3 read between the lines?

The Counterfactual • 39 implied HN points • 19 Sep 22
🕹 Technology Natural Language Processing AI Machine Learning Computational linguistics Language Models
  1. GPT-3 understands 'some' to mean 2 out of 3 letters, but it doesn't change this meaning based on how much information the speaker knows. Humans, however, adjust their understanding based on the context.
  2. When asked if the speaker knows how many letters have checks, GPT-3 gives the right answer if asked before the speaker uses specific words, like 'some' or 'all'. But afterwards, it relies on those words too much.
  3. GPT-3's way of interpreting language is different from how humans do it. It seems to have a fixed meaning for words without considering the situation, unlike humans who use context to understand better.
