Decision-making forest and convolutional neural network er

Many people now think that neural networks can resemble the mechanisms in the human brain. I think, perhaps, some of the mechanisms in the human brain are similar, but it must be a complex system. Because the human brain does not run so fast, it can recognize the universe. So intuitive to see the human brain should be a knowledge base plus a FAST index plus cascade recognition algorithm, the reason for cascading is because to ensure speed.But we can r

Neural network and deep Learning notes (1)

Neural network and deep learning the book has been read several times, but each time there will be a different harvest.The paper of DL field is changing rapidly. There's a lot of new idea coming out every day, I think. In-depth reading of classic books and paper, you will be able to find Remian open problems. So there's a different perspective.Ps:blog is a summar

CNN (convolutional neural Network)

CNN (convolutional neural Network)Convolutional Neural Networks (CNN) dating back to the the 1960s, Hubel and others through the study of the cat's visual cortex cells show that the brain's access to information from the outside world is stimulated by a multi-layered receptive Field. On the basis of feeling wild, 1980 Fukushima proposed a theoretical model Neocog

A programmer's neural network reverse communication

It can be considered that artificial neural network is a meta function, it can receive a fixed number of digital input and generate a fixed number of digital output. In most cases, the neural network has a layer of hidden neurons in which the hidden neurons and the input neu

The use of neural network in "pattern recognition" OpenCV CVANN_MLP_OPENCV

The OpenCV ml module implements the most typical multilayer perceptron (multi-layer perceptrons, MLP) model of the Artificial neural network (Artificial neural Networks, ANN). Since the algorithm implemented by ML model inherits from the unified Cvstatmodel base class, its t

What is the specific activation function in a neural network? Why Relu better than Tanh and sigmoid function

, it is easy to have a gradient disappear (when the sigmoid near the saturation zone, the transformation is too slow, resulting in a trend of 0, this situation will cause information loss, so that can not complete the training of deep Network)Third: Relu will make some neurons output 0, which results in the sparse network, and reduce the interdependence of parameters, to alleviate the problem of overfitting

To teach you to use Keras step-by step to construct a deep neural network: an example of affective analysis task

Constructing neural network with Keras Keras is one of the most popular depth learning libraries, making great contributions to the commercialization of artificial intelligence. It's very simple to use, allowing you to build a powerful neural network with a few lines of cod

Cyclic neural Network (RNN) model and forward backward propagation algorithm

In front of us, we talked about the DNN, and the special case of DNN. CNN's model and forward backward propagation algorithms are forward feedback, and the output of the model has no correlation with the model itself. Today we discuss another type of neural network with feedback between output and model: Cyclic neural network

TensorFlow is used to train a simple binary classification neural network model.

as the activation function, the category label cannot be 0 # merge X_Col = np. vstack (X_Col1, X_Col2) X_Row = np. vstack (X_Row1, X_Row2) X = np. hstack (X_Col, X_Row) Y_label = np. hstack (Y_label1, Y_label2) Y_label.shape = (num * 2, 1) return X, Y_label Here, r is the radius of the ring, w is the width of the ring, and d is the distance between the upper and lower rings (consistent with the book) 2.
