revisit Ames house prices project by using PyTorch
Given Ames Housing dataset, the project started with an exploratory data analysis (EDA) to identify the missing values, suspicious data, and redundant variables. Then I performed a mixed stepwise selection to reduce the set of variables and select the best model based on AIC, BIC, and adjust R-squared. With the best model selected, the model assumptions were checked regarding normality, homoscedasticity, collinearity, and linearity between response and predictors. Several solutions were proposed to solve the assumption violation. The model was then tested on unseen data and scored on Root-Mean-Squared-Error (RMSE).
Concrete is the single most widely used man-made material in the world. Construction workers rely on experiments to determine the strength of concrete. The app presents an attempt to predict the strength based on the information of raw materials by machine learning methods.
Implementation of an awesome trick to determine if training and test are from the same distribution
