1 The net jointly defines a function and its gradient by composition and auto-differentiation. 

2 The net is a set of layers connected in a computation graph – a directed acyclic graph (DAG) to be exact.保证前向后向通路，从硬盘加载数据到返回loss，进而进行分类等任务。

3 The net is defined as a set of layers and their connections in a plaintext modeling language.网是层的集合加上连接。

  例子：A simple logistic regression classifier is defined by

 1 name: "LogReg"
 2 layer {
 3   name: "mnist"
 4   type: "Data"
 5   top: "data"
 6   top: "label"
 7   data_param {
 8     source: "input_leveldb"
 9     batch_size: 64
10   }
11 }
12 layer {
13   name: "ip"
14   type: "InnerProduct"
15   bottom: "data"
16   top: "ip"
17   inner_product_param {
18     num_output: 2
19   }
20 }
21 layer {
22   name: "loss"
23   type: "SoftmaxWithLoss"
24   bottom: "ip"
25   bottom: "label"
26   top: "loss"
