In Week 6, you will be learning about systematically improving your learning algorithm. The videos for this week will teach you how to tell when a learning algorithm is doing poorly, and describe the 'best practices' for how to 'debug' your learning…
Logistic regression is a method for classifying data into discrete outcomes. For example, we might use logistic regression to classify an email as spam or not spam. In this module, we introduce the notion of classification, the cost function for logi…

[machine learning] Loss Function view 有关Loss Function(LF),只想说,终于写了 一.Loss Function 什么是Loss Function?wiki上有一句解释我觉得很到位,引用一下:The loss function quantifies the amount by which the prediction deviates from the actual values.Loss Function中文损失函数,适用于用于统计,经济,机…
Everything You Wanted to Know About Machine Learning 翻译了理解机器学习的10个重要的观点,增加了自己的理解.这些原则在大部分情况下或许是这样,可是详细问题详细分析才是王道,不加思索的应用仅仅能是一知半解. 所以张小龙才说'我说的都是错的'. note by 王犇 1. How Does Machine Learning Work? 一般来说机器学习算法做这三件事情来建立模型: A set of possible models to look…
