HED network git address written based on TensorFlow: Https://github.com/s9xie/hed after the hed is segmented out of the edge, it is optimized with OPENCV: Although using neural network technology, has obtained a better edge detection than the canny algorith

I ask Xi Xi, a few days ago to play with a bit of MATLAB in the use of Neural network toolbox, and suddenly there is "palpable" the sense of the well-being. The other is nothing, but the data structure of the neural network is a bit "weird", if careless will cause the toolbox error. Here is the correct open posture for

These two days in the study of artificial neural networks, using the traditional neural network structure made a small project to identify handwritten numbers as practiced hand. A bit of harvest and thinking, want to share with you, welcome advice, common progress.The usual BP neural

bp neural network in BP for back propagation shorthand, the earliest it was by Rumelhart, McCelland and other scientists in 1986, Rumelhart and in nature published a very famous article "Learning R Epresentations by back-propagating errors ". With the migration of the Times, the theory of BP neural network has been imp

0 Preface Neural network in my impression has been relatively mysterious, just recently learned the neural network, especially the BP neural network has a more in-depth understanding, therefore, summed up the following experience

1 What is a neural networkArtificial Neural Networks (Artificial Neural Networks, abbreviated as Anns) are also referred to as neural networks (NNs) or as connection models (Connection model), which mimic the behavior characteristics of animal neural networks, The mathematic

Preface This article will simply write down the calculation method of the parameters on the convolution neural network, and then compute the parameters of each common neural network. One is to strengthen the understanding of the network structure, on the other hand, the mag

Reference booksDeep learningDeep learning is a new field in machine learning research, and its motive is to establish and simulate the neural network of human brain import analysis and learning, which imitates the mechanism of human brain to interpret the data.Examples of images, sounds and text. Deep Learning is a kind of unsupervised learning. The concept of deep learning is derived from the research o

This blog will introduce a neural network algorithm package in R: Neuralnet, which simulates a set of data, shows how it is used in R, and how it is trained and predicted. Before introducing Neuranet, let's briefly introduce the neural network algorithm .Artificial neural

. Build model (Generative): Learning about the federated distribution of the observed data, such as 2-d: P (x, y). Discriminant model: The conditional probability distribution P (y|x) is learned, that is, the distribution of non-observable variables under the premise of observing the variable x.In layman's terms, we want to generate new data by generating models to learn the distribution from the data. For example, learn from a large number of images, and then create a new photo.And

Machine Learning:neural NetworkA: PrefaceDefinition of the neural network on 1,wikipedia:InchMachine Learning, Artificial neural networks (anns) is a family of statistical learning algorithms inspired byBiological Neural Networks(TheCentral Nervous Systemsof animals, in particular theBrain) and is used to estimate orap

Recurrent neural NetworksIn traditional neural networks, the model does not focus on the processing of the last moment, what information can be used for the next moment, and each time will only focus on the current moment of processing. For example, we want to classify the events that occur at every moment in a movie, and if we know the event information in front of the movie, then it is very easy to classi

Objectivethe first article of the 2017.10.2 Blog Park, Mark. Since the lab was doing NLP and medical-related content, it began to gnaw on the nut of NLP, hoping to learn something. Follow-up will focus on knowledge map, deep reinforcement learning and other content.To get to the point, this article is a introduciton of using neural networks to deal with NLP problems. Hopefully, this article will have a basic concept of natural language processing (usi

The construction of Neural Networks (neural network) is inspired by the operation of biological neural network function. Artificial neural networks are usually optimized by a learning method based on mathematical statistics, so ar

This paper summarizes the notes based on the series of machine learning techniques in Taiwan.The main content is as follows:Firstly, the structure of hypothesis and network of radial basis function network is introduced, then the RBF Neural Network learning algorithm is introduced, and the learning by using K-means is

Try the SKETCH-RNN demo. For mobile users on a cellular data connection:the the size of this the is around 5 MB of data. Everytime you to the "model in the" demo, you'll use another 5 MB of data. We made an interactive Web experiment This lets you draw together with a recurrent neural network model called SKETCH-RNN.We taught this neural net to draw by training

In the comprehensive evaluation of customer service perception of information system, it involves a lot of complex phenomena and the interaction of many factors, moreover, there are a lot of fuzzy phenomena and fuzzy concepts in the evaluation. Therefore, in the comprehensive evaluation, some scholars use the method of fuzzy comprehensive evaluation to quantify, evaluate the information System customer service awareness level, and has achieved some results. However, using this method to mo

BP (Back Propagation)The network was proposed by a team of scientists headed by Rumelhart and mccelland in 1986. It is a multi-layer feed-forward Network trained by the error inverse propagation algorithm and is one of the most widely used neural network models. The BP network
