Investigating Fandango Movie Ratings

In October 2015, a data journalist named Walt Hickey analyzed movie ratings data and found strong evidence to suggest that Fandango’s rating system was biased and dishonest. He published his analysis in this article — a great piece of data journalism that’s totally worth reading. Fandango displays a 5-star rating system on their website, where the minimum rating is 0 stars and the maximum is 5 stars. Hickey found that there’s a significant discrepancy between the number of stars displayed to users and the actual rating, which he was able to find in the HTML of the page.

Demand Forecasting of Perishable Products

The objective of this project is to minimize wastage of meal kits in retail stores. Currently, this is being done by tracking each individual item from the source until the point of sale. This is a cumbersome process and is labor intensive. In order to realize the objective using machine learning the first step in the process is to have an accurate forecast of the demand. This project focuses on generating accurate forecast for each individual item (46 unique items) for each store (47 unique stores).

Mobile App for Lottery Addiction

Many people start playing the lottery for fun, but for some this activity turns into a habit which eventually escalates into addiction. Like other compulsive gamblers, lottery addicts soon begin spending from their savings and loans, they start to accumulate debts, and eventually engage in desperate behaviors like theft. In this project, we are going to contribute to the development of a mobile app by writing a couple of functions that are mostly focused on calculating probabilities.

What about employees who have been there longer?

Finding the best markets to advertise an e-learning product

In this project, we’ll aim to find the two best markets to advertise our product in — we’re working for an e-learning company that offers courses on programming. Most of our courses are on web and mobile development, but we also cover many other domains, like data science, game development, etc. Understanding the Data To avoid spending money on organizing a survey, we’ll first try to make use of existing data to determine whether we can reach any reliable result.
