在 Hacker News 阅读原文This is a personalized news site that I wrote in two months based on algorithms from the book Programming Collective Intelligence. Please tell me what you think. It has two main features: the ability to identify related /similar links and suggestions/recommendations that actually work. The basis for all of the algorithms is a document similarity metric presented in Chapter 3: Discovering Groups. Basically, to compare document A with document B, we calculate the Pearson correlation coefficient between the word frequencies of document A and the word counts of document B. (You can imagine this as plotting a series of points of a graph: each point's x coordinate is its frequency in document A and each point's Y coordinate is its frequency in document B. The Pearson correlation coefficient is a measure of how well the line-of-best-fit fits the…
