Keras Deep Learning Framework can be used to understand what deep learning can be used to do. The following is an introduction to some basic image classification using Keras. Welcome to exchange. Reference: HTTPS://Moranzhou.github.io/Tutorials/Machine-Learning/Keras/2-3-CNN/ Version I used: Python2.7, numpy1.13.1, Theano0.9.0, Keras2.0.6, h5py2.5.0, opencv2.4.13, WIN7 system. In order to classify images, data sets are needed first, and the downloaded image data sets need to be converted into numpy matrices that Keras
This article is an improved version of my previous blog. Due to limited time, only a simple optimization has been made.

MultiLabel means that a sample may belong to multiple classes at the same time, that is, there are multiple labels.For example, for an L-sized cotton-padded jacket, the sample has at least two labels-model number: L and type: winter clothing.Only two links are posted here for reference:To solve the problem of multi-label classificationLearning Problems of multi-label Data

use function mapminmax
1 The default map range is [-1,1 ], so if [ 0,1 ] is required, provide the parameters in this format:
MappedData = mapminmax(OriginalData, 0, 1);
2 is only normalized by rows. If it is a matrix, each row is normalized separately. If the whole matrix needs to be normalized, use the following method:
FlattenedData = OriginalData(:)';The % expansion matrix is a column and then transposed to a row.
The Method of Running libsvm under weka http://datamining.xmu.edu.cn/bbs/forum.php?mod=viewthread&tid=120 weka 3.6.9 failed to install using the " old method" below!" problemevaluating classificator rand" error thrown!
1. first install WEKA3.7.9, install libsvm with tools-package manager, and then find libsvm.jar in wekafiles\packages\LibSVM\lib under the user directory.
2. Install WEKA3.6.9, and put libsvm.jar in the first step into the installation directory of WEKA3.6.9.（）
3. amend the RunWeka.ini document of WEKA3.
1, block level element display:block a, each block-level element starts from a new row, and the following elements also start from another row.(A block-level element has an exclusive row)
b, element height, width, row height, and top and bottom margin can be set. c, element width is 100% of its own parent container (consistent with the width of the parent element) without setting, unless a width is set.
