convolutional neural networks for sentence classification

ExplainThis allows us to learn to predict a person ' s identity using a Softmax output unit, where the number of classes equals the Number of persons in the database plus 1 (for the final "not in Database" Class).Reasons for the above options error:1, plus 1 explanation error:Put someone's photo into the convolutional neural network, use the Softmax unit to output the kind, or label, to correspond to these

, 10 categories corresponding to 10 radial basis function units, 84 inputs per unit, Output RBF unit calculates the input vector and the class tag vector Euclidean distance, the farther the larger.alexnet,2012, Geoffrey hintion and student Alex Krizhevsky, Ilya Sutskever, ImageNet classification with deep convolutional Neural

, then the SOFTMAX layer. In this paper, the whole connection layer is used as the representation of the image. At the fully connected layer, the output of the fourth and third layers of max-pooling is used as the input of the fully connected layer, so that the local and global characteristics can be learned.5 Reference Resources [1] Http://deeplearning.stanford.edu/wiki/index.php/UFLDL%E6%95%99%E7%A8%8B Gardenia to Stanford Deep Learning research team's translation of deep learning tut

units of the F5 layer. The F6 layer has 84* (120+1) = 10,164 parameters that can be trained.Like the classical neural network, the F6 layer calculates the dot product between the input vector and the weight vector, plus a bias.7. Output LayerThe output layer consists of a European radial basis function (Euclidean Radial Basis function) unit, one unit per class, each with 84 inputs.In other words, each output RBF unit computes the Euclidean distance b

this you can make your Exi Sting DataSet even larger, just with a couple easy transformations. Like the we ' ve mentioned before, when a computer takes an image as an input, it'll take in an array of pixel values. Let's say that the whole image is shifted left by 1 pixel. To your and me, this is imperceptible. However, to a computer, this shift can is fairly significant as the classification or label of the image doesn ' t change, W Hile the array do

Deep learning over the past few years, the feature extraction capability of convolutional neural Networks has made this algorithm fire again, in fact, many years ago, but because of the computational complexity of deep learning problems, has not been widely used. As a general rule, the convolution layer is calculated in the following form: where x represents the
