situation will help improve the accuracy of target recognition. Because small targets are usually magnified and then identified, which leads to blurring.(2) Comparison of different feature pairs (database of 416 images)The corresponding point is above the diagonal, the first method is better, the second method is just the same. In most cases, unsupervised CNN is better than overseeing CNN.(3) 48 Image Library Experimental resultsThe results are similar to the 416 images, and are not mapped and
C ++ convolutional neural network example: tiny_cnn code explanation (9) -- partial_connected_layer Structure Analysis (bottom)
In the previous blog, we focused on analyzing the structure of the member variables of the partial_connected_layer class. In this blog, we will continue to give a brief introduction to other member functions in the partial_connected_layer class.

A recurrent neural network (RNN) is a class of neural networks that includes weighted connections within a layer (compared With traditional Feed-forward networks, where connects feeds only to subsequent layers). Because Rnns include loops, they can store information while processing new input. This memory makes them id

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

The BLOBs in Caffe have 4 dimensions, respectively num,channel,width and height;
In which we define each network layer, a commonly used parameter numout, is the designated channel;
For example, the dimension is 1*3*5*5 data input network (that is, each time input a 5*5 size 3-channel graph), after a stride for 2,pad 1,kernel for 2,numout to 2 of the

The effective information that makes Caffe work for you is distributed in many different tutorials, source code on GitHub, IPython Notebook and forum themes. That's why I took the time to write this tutorial and related code. After I have summed up the knowledge I have learned, I will read it from the beginning.I think Caffe has a bright future--just adding new features will not only grow horizont
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:
