what is Java EE?Is it really what you understand?
Java EE, formerly known as J2EE, whose core consists of a series of abstract standard specifications, is a solution to the problems commonly faced in current software development.
Pay attention to the word " abstract" in the above definition.Java EE is just a set of interfaces and specifications, providing a public API for developers.
These abstract specifications can also be said to be standards.
Book isbn bar code is a one-dimensional bar code printed on the lower right side of the back of the book, which can be read with a scanning gun with high speed and accuracy.Most of the time, we need to generate the one-dimensional barcode in batch, input the isbn number to be converted into a column in xls, and then use this tool software to automatically generate the corresponding one-dimensional code.
Looking at the milestone of CNN network, the latest deep residual network ResNet
Microsoft's deep residual network ResNet originated from 2016 CVPR best paper-deep residual learning for image recognition, paper: pdf
This 152-layer ResNet architecture is deep. In addition to setting a record on the number of layers, the error rate of ResNet is surprisingly low, reaching 3.6%, and human beings are at a level of about 5% ~ 10%.

Generally, dimensionality reduction is required for high-dimensional data. In matlab, pca is used for data analysis and principal component analysis: Principal Component Analysis. Matlab calls PCA as follows: XMean = mean(X);%X每行是一个实例，每列代表一个属性 X = bsxfun(@minu
