That is, to weaken the importance of feature engineering and to use complex nonlinear models to learn the relationship between features and to enhance their expressive ability. The deep neural network model is such a non-linear model.is a deep

Here is the [1] derivation of the BP algorithm (backpropagation) steps to tidy up, memo Use. [1] the direct use of the matrix differential notation is deduced, the whole process is very concise. And there is a very big advantage of this matrix form is that it is very convenient to implement the programming Control.But its practical scalar calculation deduction also has certain advantages, for example, can clearly know that a weight is affected by who.

In the deep network, the learning speed of different layers varies greatly. For example: In the back layer of the network learning situation is very good, the front layer often in the training of the stagnation, basically do not study. In the opposite case, the front layer learns well and the back layer stops learning.This is because the gradient descent-based le

The increment rule asymptotically converges to the minimum error hypothesis, which may take an infinite amount of time, but will converge regardless of whether the training sample is linear or not.To understand this, we consider the classification of two types of flowers after iris data (here we look at the first two categor

Neural networks have many advantages over the traditional methods of classification tasks. Application: A series of WORKS2 managed to obtain improved syntactic parsing results by simply replacing the linear model of a parse R with a fully connected Feed-forward network. Straight-forward applications of a Feed-forward network as a classifier replacement (usually

LSTM (long-short term Memory, LSTM) is a time recurrent neural network that was first published in 1997. Due to its unique design structure, LSTM is suitable for handling and predicting important events with very long intervals and delays in time series.
