machine learning and neural networks

TensorFlow deep learning convolutional neural network CNN, tensorflowcnn I. Convolutional Neural Network Overview ConvolutionalNeural Network (CNN) was originally designed to solve image recognition and other problems. CNN's current applications are not limited to images and videos, but can also be used for time series signals, for example, audio signal and text

are some parameters to be trained to approximate the set of parameters mentioned in the preceding article F (x). In the parameter space, F (x) is just a point, and the model I mentioned is also a point, and because the parameters can be changed, all I have to do is to get this point of my model as close as possible to the point of the real f (x). There are many model algorithms for machine learning, but th

Gradient Based Learning 1 Depth Feedforward network (Deep Feedforward Network), also known as feedforward neural network or multilayer perceptron (multilayer PERCEPTRON,MLP), Feedforward means that information in this neural network is only a single direction of forward propagation without feedback mechanism. 2 Rectifier Linear unit (rectified linear Unit,relu),

The inverse propagation algorithm (back-propagtion algorithm), BP learning is a supervised learning algorithm, which is an important method of artificial neural network learning, which is often used to train feedforward multilayer perceptron neural networks.First, the princi

Take two anchor boxes for example, originally 3*3*8 become 3*3*2*8.9.YOLO Algorithm Before learning the basic elements of target detection, these elements can be combined to form the YOLO algorithm:-Input x (100*100*3), di

Preface This article first introduces the build model, and then focuses on the generation of the generative Models in the build-up model (generative Adversarial Network) research and development. According to Gan main thesis, gan applied paper and gan related papers, the author sorted out 45 papers in recent two years, focused on combing the links and differences between the main papers, and revealing the research context of the generative antagonism network.
