Deep understanding of Java Virtual Machine-learning notes and deep understanding of Java Virtual Machine
JVM Memory Model and partition
JVM memory is divided:
1.Method Area: A thread-shared area that stores data such as class information, constants, static variables, and Code Compiled by the real-time compiler loaded by virtual machines.
2.Heap:The thread-shared

Do not say anything, actual combat Java Virtual Machine, good study, Day day up! Develop a learning plan for your own weaknesses.Part of the content to read, do their own study notes and feelings.Java is very simple to learn, but it is difficult to understand Java, if your salary is not more than 1W, it is time to go deep into the study suddenly.5 Notes while learning

The input data part is identified, some are not identified, such a learning model can be used to predict, but the model first need to learn the internal structure of the data in order to reasonably organize the data to be
We have developed a false news detector using machine learning and natural language processing, which has an accuracy rate of more than 95% on the validation set. In the real world, the accuracy rate should be lower than 95%, especially with the passage of time, the way the creation of false news will change.
Because of the rapid development of natural language processing and
After 2 months of knowledge of machine learning. I've found that machine learning has a variety of directions. Page sort. Speech recognition, image recognition, recommender system, etc. Algorithms are also varied. After seeing the other books, I found that except for the K-m
is all 0. And because it can be deduced that b=1nz∗zt=wt∗ (1NX∗XT) w=wt∗c∗w, this expression actually means that the function of the linear transformation matrix W in the PCA algorithm is to diagonalization the original covariance matrix C. Because diagonalization in linear algebra is obtained by solving eigenvalue and corresponding eigenvector, the process of PCA algorithm can be introduced (the process is mainly excerpted from Zhou Zhihua's "machine
Support vector machine-SVM must be familiar with machine learning, Because SVM has always occupied the role of machine learning before deep learning emerged. His theory is very elegant, and there are also many variant Release vers
The last three weeks of Andrew Ng's machine learning were recently followed by the linear regression (Linear Regression) and logistic regression (logistic Regression) models in machines learning. Make a note here.Also recommended a statistical study of the book, "Statistical Learning method" Hangyuan Li, Book short, on
Non-supervised learning:
In this learning mode, the input data part is identified, the part is not identified, the learning model can be used for prediction, but the model first needs to learn the internal structure of the data in order to reasonably organize the data to make predictions. The application scenarios include classification and regression, and t

In the machine learning algorithm, for many supervised learning models, the loss function of the original model needs to be constructed, then the loss function is optimized by the optimization algorithm in order to find the optimal parameter. In the optimization algorithm of machine

However, two books are recommended for those who have just contacted NLTK or need to know more about NLTK: One is the official "Natural Language processing with Python" to introduce the function usage in NLTK, with some Python knowledge, At the same time the domestic Chen Tao classmate Friendship translated a Chinese version, here you can see: recommended "natural language processing with Python" Chinese translation-nltk supporting book; another

Originally this article is prepared for 5.15 more, but the last week has been busy visa and work, no time to postpone, now finally have time to write learning Spark last part of the content.第10-11 is mainly about spark streaming and Mllib. We know that Spark is doing a good job of working with data offline, so how does it behave on real-time data? In actual production, we often need to deal with the received data, such as real-time
