hanging nodes gradually absorb the PageRank value, resulting in PageRank black hole, which is unfair to other nodes. There are two main ways to handle hanging nodes. The first method is mentioned in the PageRank paper published by Google, specifically: Delete the suspension link to the suspension node (this may make a non-suspension node A new suspension node, so iterative deletion is required), calculate the PageRank value of the remaining non-hanging nodes until convergence, then

Data Cleaning[edit] Once processed and organized, the data may be incomplete, contain duplicates, or contain errors. The need for data cleaning would arise from problems in the the-the-same-data is entered and stored. Data cleaning is the process of preventing and correcting these errors. Common tasks include record matching, deduplication, and column segmentation.[4] Such data problems can also be identified through a variety of analytical techniques. For example, with financial information

The Viterbi algorithm can solve the most likely state sequence problem of the Hidden Markov Model. On Wikipedia, a python example is provided for the Viterbi algorithm. The original Article address is as follows: Http://zh.wikipedia.org/wiki/%E7%BB%B4%E7%89%B9%E6%AF%94%E7% AE %97%E6%B3%95 Since we are learning Ruby recently, we have migrated this algorithm from Python to Ruby. the syntax of these two languages is very close, so it is not difficult to
