1. Model representationFirst of all, a simple learning algorithm-linear regression, through the analysis of linear regression model can understand the process of supervised learning algorithm.Looking at a price forecast, we use a city's house price information set to predict the relationship between house prices and housing area.Based on the information in the picture, how do we predict the sale price of a house with an area of 1250? A straightforward

necessary to properly set the index value of each line, which is also the difference between convolutional neural network and the general full-link layer.The 2nd layer: The 2nd layer is also a feature layer, it is composed of 50 feature images, each feature image is the size of the 5*5, this feature image each point is from the previous layer 6 features image of each image to take 25 neighborhood points in the last weighted together, so each point is a node has (5* 5+1) *6=156 A link line, then

1. in Oracle, any arithmetic expression containing null values calculates the result space-time value. But for character Operators |, because the method for processing zero character values before the Oracle object is the same as the method for handling null values (it is still true in the later version), the bitwise | and null values are equal to zero characters. For example: SQL> select ename, Mgr, ename | Mgr, Sal, comm, Sal + comm from EMP;Ename Mgr ename | Mgr Sal comm Sal + comm-----------
