SAMPLING Bagging vs Pasting

One way to get a diverse set of classifiers is to use very different training algorithms,as just discussed. Another approach is to use the same training algorithm for everypredictor but to train them on different random subsets of the training set. Whensampling is performed with replacement, this method is called bagging(short for bootstrap aggregating). When sampling is performed without...

squared hinge loss

The squared hinge loss is a loss function used for “maximum margin” binary classification problems. Mathematically it is defined as: where ŷ the predicted value and y is either 1 or -1. Thus, the squared hinge loss is: 0* when the true and predicted labels are the same and* when ŷ≥ 1 (which is an indication that the classifier is sure that it’s the correct label)quadratically increasing with the...

Dealing with missing data

petamind

In real-world data, there are some instances where a particular element is absent because of various reasons, such as corrupt data, failure to load the information, or incomplete extraction. Handling the missing values is one of the greatest challenges faced by analysts because making the right decision on how to handle it generates robust data models. Let us look at different ways of imputing...

SECURITY GROUPS VS NETWORK ACLS

As the two common method for securing the cloud, the differences between NACL (network access control list) and security groups have been discussed below: Network ACLSecurity GroupNetwork Access Control List that helps provide a layer of security to the amazon web services. There are two kinds of NACL- Customized and default.A security group has to be explicitly assigned to an instance; it...

Celebrating 5k+ Stack overflow

It has been a while since I joined Stack Overflow. As a programmer, I would like to acknowledge the creators and all contributors to the website. It has been an awesome resource for developers and other fields of interest. Stack Overflow is a question-and-answer site for professional and enthusiast programmers. It is a privately-held website, the flagship site of the Stack Exchange...
