In Caffe, there are currently two ways to visualize the Prototxt format network structure : using Netscope online visualization to use the draw_net.py provided by Caffe
In this paper, we will introduce the two methods of 1. Netscope: An online visualization tool for neural network architecture supporting Caffe

Neural network and deep learning the book has been read several times, but each time there will be a different harvest. DL field of paper, every day there will be a lot of new idea out, I think, in-depth reading classic books and paper, must be able to find Remian open problems, so there is a different perspective.Ps:blog is a summary of important contents in the main extract book.Summary section
Weight vector W, training sample X1. Initialize the weight vector to 0, or initialize each component to any decimal between [0,1]2. Input the training sample into the Perceptron to get the classification result (-1 or 1)3. Update weight vectors based on classification resultsPerceptron algorithm for Tuyi data samples that are linearly delimitedMachine learning--perceptron data classification algorithm step (MU-class network-to achieve a simple
The training process for the BP network consists of the following steps:Step One: Network initialization.Step two: Implicit layer output calculation.Step three: Output layer output calculation.Step four: Error calculation.Step five: Weight update.Step Six: Threshold updates.Step Seven: Determine whether the iteration of the algorithm ends, and if not, return to step two.Speech feature signal recognition:The

Pybrain is a well-known Python neural network library, today I used it to do an experiment, referring to this blog, thanks to the original author, gave a specific implementation, the code can be directly copied to run.Our main problems are as follows:First we give a function to construct the dataset that is required to generate this problem .
Def generate_data (): "" "

Abstract: With the development of computational intelligence, artificial neural network has been developed. The industry now considers that it may not be appropriate to classify neural networks (NN) in artificial intelligence (AI), and that the classification of computational Intelligence (CI) can explain the nature of the problem. Some topics in evolutionary com
Keras Introduction?? Keras is an open-source, high-level neural network API written by pure Python that can be based on TensorFlow, Theano, Mxnet, and CNTK. Keras is born to support rapid experimentation and can quickly turn your idea into a result. The Python version for Keras is: Python 2.7-3.6.?? Keras, a Greek-like "horn" (horn), was first released in March 2015 and can run on Windows, Linux, Mac and ot
First, prepare
In order to understand the neural network more deeply, the author adopts the pure C + + handwritten method, in which the operation of the Matrix is called OpenCV, and the dataset comes from the public dataset A1A.Experimental environment: Visual Studio 2017 opencv3.2.0 A1A Data set
This article closely follows the previous article depth study practice (i)--logistic regression. Ii. The basis
In Keras, a neural network visualization function plot is provided, and the visualization results can be saved locally. Plot use is as follows:
From Keras.utils.visualize_util import plot
plot (model, to_file= ' model.png ')
Note: The author uses the Keras version is 1.0.6, if is python3.5
From
keras.utils
import
plot_model

However, this feature relies on the
Optimization algorithm is an important part of machine learning, BP Neural network is the foundation of deep Learning, BP neural network principle is very simple, almost can be understood as a logistic regression of a set way, in the previous blog post, I use r language to achieve several optimization algorithms, Based

Reference:Spatial Transformer Networks [Google.deepmind]Reference:[theano source, based on lasagne] chatter: Big data is not as small as dataThis is a very new paper (2015.6), three Cambridge PhD researcher from DeepMind, a Google-based new AI company.They built a new local network layer, called the spatial transform layer, as its name, which can transform the input image into arbitrary space, for the characteristics of CNN.In my paper [application an
At the request of a friend wrote a python implementation of the single hidden layer of BP Ann Model code, long time no blog, the way to send up. This code is relatively neat, relatively pure description of the basic principles of Ann, beginners machine learning can refer to students.Some of the more important parameters in the model:1. Learning RateThe learning rate is an important factor that influences the convergence of the model, in general, it should be flexibly adjusted according to the sp
The Artificial Neural network (Artificial neural Networks), as its name implies, is modeled after the neuron structure of the NPC. is an artificial neural network model with hidden layers. X = (x1,x2,.., xm) is the input of the Ann, which is the value of a record on M proper
TensorFlow let neural networks automatically create musicA few days ago to see an interesting share, the main idea is how to use TensorFlow teach neural network automatically create music. It sounds so fun, there's wood! As a Coldplay, the first idea was to automatically generate a music like the Coldplay genre, so I started to follow the tutorial on GitHub (proj
certain assumption. What assumption? You'll know later.1. CNN FeaturesCNN stands out from traditional NN in 3 area:
Sparse Interaction (Connection)
Parameter sharing
Equivariant representation.
Actually the third feature is more like a result of the first 2 features. Let's go through them one by one.
Fully Connected NN
nn with Sparse connection
Sparse Interaction , unlike fullly connected

Use the color sensor to read the color of the ph test strip and then get the ph value he represents. At first, I wanted to fit a function about RGB and ph, but it always worked poorly. The neural
Artificial neural network is a simulation of the biological nervous system. Its information processing function is determined by the input and output characteristics (activation characteristics) of the network Unit (neuron), the topology of the network (the connection mode of the neuron), the connection weight (synapti

It is called "googlenet" rather than "googlenet", and the article says it is to salute the early lenet.IntroducedDeep learning and the rapid development of neural networks, people are no longer focused on more hardware, larger datasets, larger models, but more attention to new idea, new algorithms and model improvements.In general, t
