Automate Feature Engineering using Sklearn Pipeline and feature-engine library

Make your feature engineering steps repeatable and get predictions from a new dataset with only one line of code — During model building, feature engineering is generally the most challenging part. You need to check for data types and distributions, fill missing data, make necessary transformations, reduce cardinality of categorical variables when necessary, and so on. It takes too much time and effort. When working in the research environment, that…

Time-series Forecasting using LSTM (PyTorch implementation)

Exploring implementation of long short-term memory network using PyTorch and weather dataset — In my previous time series post, I explored SARIMA for monthly weather forecasting. In this new post, I will be using LSTM for daily weather forecasting and show that LSTM is performing better for weather data as (i) can easily utilize multidimensional data, (ii) can make daily prediction where SARIMA…

Time Series Forecasting using SARIMA (Python)

Exploring Seasonal Autoregressive Integrated Moving Average models using Python and weather dataset — ARMA models are widely used in time series forecasting. In compare to ARMA models, SARIMA models can be used even if the data is not stationary and there is a seasonality component. There are not many Python implementation details of SARIMA models on the internet. On top of that, resources…

Frequentist vs Bayesian A/B Testing

We will discover Frequentist approach and Bayesian approach in A/B testing using Python — A/B testing is widely used in commercial setting to maximize the profit. Online newspapers are trying different titles for their articles to maximize click rates, mobile games are trying different offers to convince you for in-app purchases, and so on. Even though frequentist approach in A/B testing is widely used…
