In the current recommendation system, many use machine learning, some have used deep learning. So, is machine learning equivalent to a bunch of algorithms? The answer is: machine learning ≠ algorithm. Machine learning ≠ algorithm When we open a textbook or university syllabus, we usually see a bunch of algorithm lists. This leads to the […]

Machine learning practitioners have different personalities, although some of them will say “I am an expert in X, X can train any type of data”, where x is an algorithm. However, we have to admit that in real life, there is no X that can train any kind of data. Some algorithms are suitable for […]

The basic principle of naive Bayes is to use prior probability to calculate posterior probability. For prior probability and posterior probability, please refer to the simplest understanding of prior probability and posterior probability. 1. Suppose there is a data set X, including X1 to xn pieces of data. Each piece of data contains M features […]
