Learning技术可以用于 scientists, engineers, data analysts, or quants, but also less technical individuals with degrees in non-quantitative fields such as the social sciences or business. 此书regression & classification交杂(注意这个只看y的类型),介绍各种方法 难点是how to choose the best method for a...
2.supervised learning “right answers”given supervised learning:数据集中的每个数据都是正确的答案 Regression Question : predict continuous valued output (Regression Question) key : predict ;continuous data;回归问题 Classification Problem: discrete valued output;分类问题 a lot of features 如何处理无穷...
Machine learning: Classification What is Classification? Linear regression assumes that the reponse variable is quantitative variable. But in many situations, the response could be qualitative variable, such as the status of marriage, gender, and so on. Usually qualitative variables are referred to as...
Machine learning computer programs are constantly fed these models, so the programs can eventually predict outputs based on a new set of inputs. Regression and classification are two of the more popular analyses under supervised learning. Regression analysis is used to discover and predict ...
Machine Learning: Classification 2 A quick review on logsitc regression Logistic regression tries to model the relationship between predictors and the conditional disrtibution of the responseYgiven the predictors X using logistic function. logistic regression also has several assumptions...
Classification: predict categories which can be smallfinitenumber of possible outputs 2.3 小结 3. 非监督学习(Unsupervised Learning) 对于监督学习,相应的数据集中我们可以得到每条样例数据对应的标签(label);而在非监督学习中,不存在这样一个标签(label)。
This is where machine learning and its many techniques come into play. In this chapter, we will introduce machine learning as a practice along with some of its most basic and critical techniques such as regression and classification. In doing this, we will also discuss other critical details ...
