recognition work, the final model of the accuracy reached 100%. We get the following table:Analyzing the above table, we find that by increasing the three steps in pipeline, we can add 17%, 1%, 10% respectively to the accuracy of the model. We have reached the upper limit of three steps in advance (the performance of three steps is optimized to 100%, not better), the resulting three sets of data is also the upper limit, this is the upper limit analysis. As a result, we know that optimization of

Python has become one of the most commonly used languages in artificial intelligence and other related sciences due to its ease of use and its powerful library of tools. Especially in machine learning, is already the most favored language of major projects.
In fact, in addition to Python, there is no shortage of developers in
learning is a branch of artificial intelligence that involves the use of techniques to allow computers to improve their output based on previous experience. This area is closely related to data mining and often requires the use of a variety of techniques, including statistics, probability theory, and pattern recognition. Although machine learning is not an emerg

The main learning and research tasks of the previous semester were pattern recognition, signal theory, and image processing, which in fact had more or less intersection with machine learning. As a result, we continue to read machine learning in depth and watch Stanford's

Finally the accuracy of the model reached 100%. We get the following table:Analyzing the above table, we found that by upgrading the three steps in pipeline, we were able to add 17%, 1%, 10% respectively to the accuracy of the model. We have reached the upper limit of three steps in advance (the performance
In this article we will outline some popular machine learning algorithms.Machine learning algorithms are many, and they have many extensions themselves. Therefore, how to determine the best algorithm to solve a problem is very difficult.Let us first say that based on the learning approach to the classification of the

Decision Tree Learning
The decision tree method is used to establish a decision model based on the actual data attribute values. Decision Making uses a tree structure until prediction decisions are made based on a given record. Decision tree training is performed on data of classification and regression.

in some cases, more accurate.There is also an unsupervised learning anomaly detection, such as monitoring abnormal credit card transactions to prevent fraud, capturing defects in manufacturing, and automatically removing outliers (outliers, extreme values, outliers) from the data set. By training the model with normal data and then applying it to the new data, it can tell us whether the new data is normal.
