TensorFlow is used to train a simple binary classification neural network model. Use TensorFlow to implement the 4.7 pattern classification exercise in neural networks and machine learning The specific problem is to classify the dual-Crescent dataset as shown in. Tools used: Python3.5 tensorflow1.2.1 numpy matplotlib 1. Generate a two-month Dataset Def produceData (r, w, d, num): r1 = r-w/2 r2 = r + w/2 #

The Ndarrray in List/tuple,numpy in Python and the tensor in TensorFlow.In Python, List/tuple understands that a sequence of data is understood only from the memory point of view, not the number of mathematical bids, vectors, and tensor.From the Python memory point of view, is a numeric value, length 1, and is not a sequence;From the perspective of NumPy and TensorFlow mathematics, it is a scalar, shape is (), its axis is 0;[1,2,3,4,5,6]From the Pytho

Objective Some time ago because the subject needs to use a period of time tensorflow, feel this framework is very interesting, in addition to can build complex neural network, but also can optimize the other needs of the calculation model, so I always want to learn to write a similar diagram calculation framework. In the last few days, the group will finish the decision to implement a rough version diagram computing framework that mimics the

In the deep learning network structure, the categories of each layer can be divided into these kinds: convolution layer, full connection layer, Relu layer, pool layer and reverse convolution layer. At present, in pixel-level estimation and end-to-end learning problems, full convolution network shows his advantage, there is a very important layer, the convolution of the feature map sampling (deconvolution) to the input image dimension space, is the deconvolution layer. So how does it come to be a

TensorFlow and Theano and Keras are deep learning frameworks, TensorFlow and Theano are more flexible and difficult to learn, they are actually a differentiator. Keras is actually TensorFlow and Keras interface (Keras as the front end, TensorFlow or Theano as the back end), it is also very flexible, and relatively eas

TensorFlow model save/load When we use an algorithmic model on-line, we must first save the trained model. TensorFlow the way to save the model is not the same as Sklearn, Sklearn is straightforward, a sklearn.externals.joblib dump and load method can be saved and loaded using. and TensorFlow because of the graph, operation these concepts, save and load the mode

TensorFlow implements the Softmax regression model, tensorflowsoftmax I. Overview and complete code Tensorflow encapsulates MNIST (MixedNational Institute of Standard and Technology database), a very simple machine vision dataset, and can directly load MNIST data into the expected format. this program uses Softmax Regression to train the classification model for Handwritten Digit Recognition.

TensorFlowTensorFlow is Google's second generation of AI learning systems based on Distbelief, whose name comes from its own operating principles. Tensor (tensor) means n-dimensional arrays, flow (stream) means the computation based on data flow diagram, TensorFlow flows from one end of the flow graph to the other. TensorFlow is a system that transmits complex data structures to artificial neural networks f
