The log () method used to calculate the logarithm in Python
This article mainly introduces the log () method used to calculate the logarithm in Python. It is a required method for getting started with Python. For more information, see
The log ()
The main reason is that the teacher used different methods to calculate the natural logarithm and understand the characteristics of different parallel languages. So I used multithreading. After OpenMP, I want to use opencl to implement the following.
Natural language Processing--TF-IDF algorithm to extract key words
This headline seems to be very complicated, in fact, I would like to talk about a very simple question.
There is a very long article, I want to use the computer to extract its
2.1 Lexical representation(1) The use of the One-hot method to express the vocabulary has two major shortcomings, 10,000 words for example, each word needs to be represented by 10000 dimensions, and only one number is zero, the other dimensions are 1
