Statistics By Sehra Sir We had been having sessions with Sukhjit Sehra Sir on statistics since the past week. This week we learned about the following topics: Probability and Probability Distributions Probability theory developed from the study of games of chance like dice and cards.  A process like flipping a coin, rolling a die or drawing a card from a deck is called probability experiments.  An outcome is a specific result of a single trial of a probability experiment. Probability Distributions Probability theory is the foundation for statistical inference.  A probability distribution is a device for indicating the values that a random variable may have.  There are two categories of random variables.  These are discrete random variables and continuous random variables. Discrete random variable The probability distribution of a discrete random variable specifies all possible values of a discrete random variable along with their respective probabiliti...

Anomaly Detection    Session with Satnam Singh sir  All the interns had a 2 hour long session with Dr.  Satnam Singh ,chief data scientist, Acalvio technologies, Bengaluru, India. In the session, he discussed various points and issues related to cyber security and online frauds and he shared some domain knowledge on the related topics and his team's work. It was an interactive session and he also asked about the work interns were doing. He shared his experience which benefited students and we learned some new approaches and terminology. Problem statement Satnam sir shared a  kaggle problem  and asked all of us to work on it. It was a credit card fraud detection problem and was to be solved as an anomaly detection problem with statistical way without using any libraries such as scikit-learn etc. Sir gave us ample amount of time to work on it before he would review all our progress and code. So after the session, we started exploring different...
