近一个月来,我都在阅读Keras之父著作的《Python深度学习》一书。书中最常使用的便是Keras的Model类。 通过查阅官方文档和Model类源码,本文将Keras Model类中的常用方法进行了梳理和总结。

评分预测预测用户对物品评分的行为称为评分预测(rating prediction)。 评分预测的预测准确度一般通过均方根误差(Root Mean Squared Error,简称RMSE)和平均绝对误差(Mean Absolute Error,简称MAE)计算。 对于测试集中的一个用户u和物品i,令$r_{ui}$是用户对物品i的实际评分,而$\hat{r}_{ui}$是推荐算法给出的预测评分。

在讲位运算符之前,我们先来回顾下本科时学过的一些计算机基础知识。 所谓原码就是二进制定点表示法,即最高位为符号位,正数为0,负数为1,其余位表示数值的大小。 反码:正数的反码与其原码相同,负数的反码是其原码逐位求反(符号位除外)。 补码:正数的补码与其原码相同,负数的补码为其反码加1。 整数在内存中是以补码的形式存储的。
