Jan 16, 2022Building A Recommender System With Implicit Feedback Datasets Using Alternating Least SquaresRecSys, ALS, Collaborative Filtering — In real-world scenarios most feedback is not explicit but implicit. Implicit feedback is tracked automatically, like monitoring clicks, view times, purchases, etc. Thus it is much easier to collect. Think of yourself, how often you give a rating after purchasing a product vs. how often you click or purchase a…Python5 min readPython5 min read

Published inTowards Data Science·Jul 18, 2021Forecasting the 2020 US Election Using Multilevel Regression with Post-stratificationPresidential election, Trump, Political Polls, PYMC3, Python — How to Estimate Public Opinion in the States The most commonly used method for estimating state- level opinion is called disaggregation. The process is simple and easy to implement: After combining a set of national polls, you calculate the opinion percentages disaggregated by state. The problem with disaggregation is that it requires a large number of national surveys…Bayesian Statistics8 min readBayesian Statistics8 min read

For example, given a question: Could we use today’s Apple’s stock price to predict tomorrow’s Tesla’s stock price? If this is true, our…Time Series Analysis5 min readTime Series Analysis5 min read
Published inTowards Data Science·Nov 30, 2020A Bayesian Model for Estimating the Effects of Covid-19 VaccinesPYMC3, Bernoulli Distribution, Pfizer, Moderna, AstraZeneca — Because of the trials are still ongoing, researchers caution against making head-to-head comparisons of vaccines based on incomplete data. But for the sake of learning, we will do it anyway, just not making any meaningful conclusions. Recently, the announcements went out that the potential effectiveness of SARS-CoV-2 vaccine candidates developed…Bayesian Statistics4 min readBayesian Statistics4 min read
