daily_coding_problem
Solving problems by Ales Miller and Lawrence Wu. First I try my own solution, but if theirs is better, I try to optimize it. Even if there's no room for further optimization, I make sure I understand their solution as is and walk through the code.

german-credit
In this project, customers' demographic and behavioral data is available and the aim is to predict the probability of default. The target variable is "class" which takes value as "Good" and "Bad". The aim is to build a credit risk scorecard (just a set of probability values) based on the sample data provided.

did-stock-beat-s-and-p
Using various classification methods, I sought to determine the most relevant variables in a stock’s performance; securities were evaluated in a binary manner to reflect if they had surpassed the Standard and Poor 500’s (S&P-500) performance for the equivalent time period.
