Using Python and Keras for principal component analysis, neural network construction and image reconstruction
the introduce
These days, there's a ton of data in just about every app we use—listening to music, browsing a friend's images, or watching a new trailer.
Recently we were asked by a client to write a research report on image reconstruction, including some graphical and statistical output.
Principal Component Analysis PCA Di ...

NNDL experiment 6 Convolutional neural network ResNet18 implements MNIST
5.4 Handwritten Digit Recognition Experiment Based on Residual Network
Residual Network (ResNet) is a way of adding directly connected edges to nonlinear layers in neural network models to alleviate the problem of gradient disappearance, thereby making it easier to train deep neural networks. In the residual network, the most basic unit is th ...

MNIST libtorch practical exercise
Ready to work
First download the MNIST database, http://yann.lecun.com/exdb/mnist/
After downloading, do not decompress it with software such as winrar. For example, t10k-images-idx3-ubyte is decompressed into t10k-images.idx3-ubyte. It is best to decompress it with tar in Linux environment.
Suppose you unzip t ...

[Flying Paddle] Target Detection YOLO-V3 Study Notes
Before learning this course, I heard the name of YOLO. During the epidemic, an up master trained the detection of pedestrian masks through yolo and it was a great success. Without further ado, let's start learning.
Basic Concepts in Object Detection
Before starting to learn YOLO, first learn some basic concepts of target detection. After all, Y ...
