-notes for the "Deep Learning book, Chapter Sequence modeling:recurrent and recursive Nets. Meta Info:i ' d to thank the authors's original book for their great work. For brevity, the figures and text from the original book are used without. Also, many to Colan and Shi for their excellent blog posts on Lstm, from which we use some figures. Introduction Recurrent neural Networks (RNN) are for handling data.

How the reverse propagation algorithm works In the previous article, we saw how neural networks learn through gradient descent algorithms to change weights and biases. However, before we discussed how to calculate the gradient of the cost function, this is a great pity. In this article, we will introduce a fast computational gradient algorithm called reverse propagation.

" because of "mountain climbing". The stochastic neural networks to be explained in this paper: Simulated annealing (simulated annealing) and Boltzmann machines (Boltzmann machine) are capable of "mountain climbing" by certain probability to ensure that the search falls into local optimum. The comparison of this image can be see:There are two main differences between random

There ' s something magical about recurrent neural Networks (Rnns). I still remember I trained my recurrent network forimage. Within a few dozen minutes of training my The baby model (with rather Arbitrarily-chosen hyperparameters) started to Gen Erate very nice looking descriptions of images this were on the edge of making sense. Sometimes the ratio of how simple your model are to the quality of the result

Next. The previous two articles explained that neural networks are a black box with a small sphere (neuron) connected one by one. By changing the connection mode and parameters of neurons, you can implement a compliant neural network. Next we will give an example of a BP neural network to deepen our understanding. Befo

. We use the cublas. lib and curand. Lib libraries. One is matrix calculation and the other is random number generation. I applied for all the memory I needed at one time. After the program started running, there was no data exchange between the CPU and GPU. This proved to be very effective. The program performance is about dozens of times faster than the original C language version (if the network is relatively large, it can reach a speed-up ratio of

convolutional neural Network Origin: The human visual cortex of the MeowIn the 1958, a group of wonderful neuroscientists inserted electrodes into the brains of the cats to observe the activity of the visual cortex. and infer that the biological vision system starts from a small part of the object,After layers of abstraction, it is finally put together into a processing center to reduce the suspicious nature of object judgment. This approach runs coun

to stop training.Limiting the size of the weightsThis section describes how to control the capacity of a network by limiting the size of the weights, and the standard method is to introduce a penalty to prevent the weights from becoming too large. Along with some implicit assumptions, neural networks with small weights are much simpler than power values. We can use several different methods to limit the we

3D Graph Neural Networks for RGBD Semantic segmentation2018-04-13 19:19:481. Introduction:With the development of depth sensors, RGBD semantic segmentation is applied to many problems, such as virtual reality, robot, human-computer interaction and so on. Compared with the existing 2D semantic segmentation, RGBD semantic segmentation can use real-world geometric information to assist segmentation by explorin

object always correspond to the same block of standard pixels of the image. In addition, the box can provide invariance for many different degrees of freedom: translation, rotation, scale, shear, stretch, and so on. However, it is very difficult to choose a box, because there may be some problems such as segmentation error, covering, singular angle of view and so on.The method of brute force generalization (the Brute forces normalization approach) is given.The third and fourth methods are descr

Neural Networks are getting angry again. Because deep learning is getting angry, we must add a traditional neural network introduction, especially the back propagation algorithm. It is very simple, so it is not complicated to say anything about it. The neural network model is shown in Figure 1: (Figure 1) (Figure 1)

squared error is used, bad predictions take a dominant position. Then we do a mathematical calculation, we assume that y¯\overline{y} to good guy and bad guy are the same distance, and then do a calculation to get the equation in the figure above. But this kind of equation is not always set up, this is mainly because we are using squared error. In exchange for an error measurement, the equation is not necessarily true. The following figure shows an example. The following figure shows a number

Weight sharing the word was first introduced by the LENET5 model, in 1998, LeCun released the Lenet network architecture, which is the following:Although most of the talk now is that the 2012 Alexnet network is the beginning of deep learning, the beginning of CNN can be traced back to the LENET5 model, and its features are widely used in the study of convolutional neural networks in the early 2010--one of w
