TF-IDF algorithm is a commonly used weighted technique for information retrieval and data mining. TF means word frequency (term-frequency), the IDF means reverse file frequencies (inverse document frequency).TF-IDF is a traditional statistical algorithm used to evaluate how important a word is to a document in a document set. It is proportional to the word freque

"Google announced today the open source TensorFlow advanced software package Tf-slim, enabling users to quickly and accurately define complex models, especially image classification tasks." This is not reminiscent of a computer vision system that Facebook last week open source "Understanding images from pixel level". In any case, there are many powerful tools in computer vision. The following is the official blog post translation. Back to "0831" to do

class TF. Variable A variable maintains the state of the diagram by calling the run () method. You add a variable to the diagram by constructing an instance of the variable class. The Variable () constructor requires an initial value, which can be a tensor of any type and shape. The initial value defines the type and shape of the variable. After the construction is complete, the variable's type and shape are fixed. You can use the Assign method to mod

Reprinted from http://www.ruanyifeng.com/blog/ Last time I used TF-IDF algorithms to automatically extract keywords. Today, let's look at another issue. Sometimes, in addition to finding keywords, we also hope to find other articles similar to the original article. For example, Google News provides similar news under the main news. Cosine similiarity is used to identify similar articles ). The following is an example of cosine similarity ". For the s

To support this feature, two tools Sd_fdisk and U-boot-head-tool are required. The Sd_fdisk function is to partition the TF card, U-boot-head-tool is to modify the compilation generated u-boot to fit the s5p4418 hardware boot requirements. The download address for the two tools is http://download.csdn.net/detail/u010406724/8362055, Also requires a script to use the two tools sd_fusing.sh, the specific code is as follows: # # Copyright (C) Samsung El

There is a problem that requires the use of pure MySQL to implement a TF-IDF algorithm.The original input is a articles table with 100 columns and one word per column. In fact, the core difficulty is how to traverse the comparison of these 100 words and specified words such as ' apple ' for comparison. First of all, brute force is poor to give all the column names, such as Word1, Word2 ... But this code must be ugly ugly, and if it is 1000 columns wha

, a and B are two vectors. we need to calculate their angle θ. The cosine theorem tells us that we can use the following formula: If the vector a is [x1, y1] and the vector B is [x2, y2], you can rewrite the cosine theorem to the following form: Mathematicians have proved that this calculation method of cosine is also true for n-dimensional vectors. Assume that A and B are two n-dimensional vectors, and A is [A1, A2 ,..., an], B is [B1, B2 ,..., bn], then the cosine of the angle θ between A a

Last time, I used the TF-IDF algorithm to automatically extract keywords. Today, we are going to look at another related issue. Sometimes, in addition to finding the keyword, we also want to find other articles similar to the original article. For example, "Google News" under the main news, but also provides a number of similar news. In order to find similar articles, "Cosine similarity" (cosine similiarity) is needed. Now, let me give you an exam

TF card, also known as microSD, is a very small flash memory card, invented by a famous storage vendor, SanDisk. This card is mainly used in mobile phones, but because it has a small size, with the increased capacity, it slowly began to use in GPS devices, portable music players and some flash memory disk. The TF card insertion Adapter (adapter) can be converted to an SD card, but the SD card is not normall

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 keywords (Automatic keyphrase extraction), completely without manual intervention, how can I do it correctly? This problem involves data mining, text processing, information retrieval and many other computer frontier areas, but unexpectedly, there is a very simple classical algorithm, can give a very satisfactory resul
