Binary classification techniques are commonly used in forensic examination to test if a specimen belongs to a particular group and base the expert opinion on the questioned evidence. However, most of the currently used methods do not achieve sufficient accuracy due to the ignoring of the specimens ...
(1)首先我们的目的是要用regression来代替classification(为啥要替代?因为PLA/Pocket是NP-hard的问题,不好整;而Linear Model在最优化之后,求解比较容易了),如果regression和classification在性能上差不多,那就可以替代了。 (2)因此,我们把cross-entropy error来scale成0/1 error的upper bound,目的就是让cross-entropy ...
Training a binary classification modelTo train the model, we'll use an algorithm to fit the training data to a function that calculates the probability of the class label being true (in other words, that the patient has diabetes). Probability is measured as a value between 0.0 and 1.0, ...

binary classification 二分类 例句:1.Then starting from the concept 'scale of contexts' with a combination of two cognitive principles, we reanalyze the motivation for the binary classification mentioned above, thus indicating it is necessary to make further explorations on it by taking ...
ClassificationLinear is a trained linear model object for binary classification; the linear model is a support vector machine (SVM) or logistic regression model.

predictor variables such as age, blood pressure, sex and so on. There are many techniques that can be used to tackle a binary classification problem. In this article I’ll explain how to use the Microsoft Cognitive Toolkit (CNTK) library to create a neural network binary classification mode...
