项目日程

2014-10-20 -- 2014-11-09

确定神经网络库的选择为 Brain
确定输入格式为一个 HSL 矩阵的 flatten: H1 S1 L1 H2 S2 L2 H3 S3 L3 H4 S4 L4 H5 S5 L5
See also: https://github.com/zenozeng/cocolour/issues/72
一次概念验证性测试
```
Length:  164
Match Cound:  106
Unmatch Cound:  58
Rate(%):  64.63414634146342
```
具体的测试详情：https://github.com/zenozeng/cocolour/issues/76
确定输出格式
似乎喜欢和讨厌的机制是很不一样的，所以他们应该被丢到两个堆中去。
如果直接用单个score输出，正确率非常低，只有30%-40% 如果用喜欢，不喜欢，一般输出，大概60-61%，以及一般这一档的数据非常少，不怎么可靠。如果用喜欢, 不喜欢，大概60-68%
具体的测试详情：https://github.com/zenozeng/cocolour/issues/77
增加数据到 813 组
数据分组成 train 和 verify 组的时候引入随机性
https://github.com/zenozeng/cocolour/issues/81
这个 Issue 会导致之前的测定结果存在一定的偏差
增加数据到 1378 组
调整 learningRate 到 0.1
似乎结果的稳定性提升了一些、正确率也提升了一些
基于 master-slave 的多进程结果验证
充分利用多核性能

尝试引入色相方差、饱和度方差、明度方差
