As part of a project course in my second semester, we were tasked with building a system of our chosing that encorporated or showcased any of the Computational Intelligence techniques we learned about in class. For our project, we decided to investigate the application of Recurrent Neural Networks to the task of building a Subreddit recommender system for Reddit users. In this post, I outline some of the implementation details of the final system. A minimal webapp for the final model can be interacted with here, The final research paper for the project can be found here and my collaboraters on the project are Barbara Garza and Suren Oganesian. The github repo for the project can be found here with this jupyter notebook being here.
The goal of the project is to utilize the sequence prediction power of RNN's to...
MAI-IML Exercise 4: Adaboost from Scratch and Predicting Customer Churn
In this work, we develop a custom adaboost classifier compatible with the sklearn package and test it on a dataset from a telecommunication company requiring the correct classification of custumers likely to "churn", or quit their services, for use in developing investment plans to retain these high risk customers.
Adaboost from Scratch
Defined below is an sklearn compatable estimator utilizing the adaboost algorithm to perform binary classification. The input parameters for this estimator is the number of weak learners (which are decision tree stubs on a single, randomly selected feature) to train and aggregate to produce the final classifier. An optional weight distribution can also be passed to the classifier, which defaults to uniform if not set. This custom estimator will later be utilized to develop a classifier capable of predicting customer churn from labelled customer data.
With the recent unveiling of Tesla's Model 3 and pre-orders approaching 400,000, the internet has been buzzing with Tesla discussions and analysis. One of Tesla's key differentiators from other mass market Electric Vehicals (EVs) is its Super Charger (SC) network that provides 170 miles of range in 30 minutes source. With Elon Musk stating plans to double the size of the SC network by the end of 2017, a large amount of planning, resources and investment are being allocated to this network expansion.
An analysis exploring Tesla's Supercharger network was performed using beaker notebooks and is currently the top rated notebook published on the platform.

The Daily Fantasy Sports (DFS) industry has exploded in popularity in recent years, largely due to the exponential growth of users playing on industry titans such as Fanduel and DraftKings. These platforms allow users to gamble real money by selecting a set of players known as a roster from a sport, with rules constraining the total salary and specific player position types required for a selected roster.Each player in the roster can accumulate points based on their performance in the sport in the upcoming game that day.The user then enters this roster into contests against other users who have also entered their rosters, with the aim of selecting the roster that accumulates the most points based on the competitions set rule for point accumulation. The user or subset of users with the top accumulated points at the end of the competition win the pot of money entered...
