We started to demonstrate how to create a simple conceptual model and then let enitityframework build the underlying database. In the remaining examples, we will show you how to create a model from an existing table an

This lesson mainly describes the processing of linear models. Including: 1. Input Representation) 2. Linear Classification) 3. Linear Regression) 4. nonlinear transformation) The author believes that to test the availability of a model, it is to use real data to do a good job. To explain how to apply linear models, the author uses linear models to solve the problem of post office

relational database, a query can access cells from multiple columns in a row). You can treat a member of a column family in a row as a child row .The table is decomposed into more than one table area , equivalent to a Bigtable slice (tablet). A region contains rows in a range. Decomposing a table into multiple regions is a key mechanism for efficient processing of large tables.Each of the tables in HBase is called BigTable. BigTable stores a series of row records with three basic types of defin

Unlike SQL database, you must determine the pattern before inserting the data and declaring a table,the collection of MongoDB does not execute the document structure. He has the flexibility to conveniently map files to an entity or object. Each document can match the entity represented by the

To exclude form verification, for example, if you want to call a Model method in the controller, transfer it to one of the parameters in this method, for example, $ city_id is actually the $ city_id, that is, it can be an int or an array. So where are the $ city_id POST at this time...

Since I am involved in a license plate recognition system project, I plan to use the Deep Learning Library Caffe to identify the license plate characters. Starting with Caffe, I'm going to use each of the network models in the example first, and of course the violent use is not going to have a good result--| | | , so here is just a sample of the network model using the steps, the accuracy of the final test for the moment no matter!First, the picture d
