Data Science Simplified Part 9: Interactions and Limitations of Regression Models

#artificialintelligence

In the last few blog posts of this series discussed regression models at length. The term engine size x width is the interaction term. Hierarchical Principle: When interactions are included in the model, the main effects needs to be included in the model as well. In the last few blog posts, simple linear regression model was explained.


Data Science Simplified Part 8: Qualitative Variables in Regression Models

The model predicts or estimates price (target) as a function of engine size, horsepower, and width (predictors). The sample data has 5 cars, and each car has a diesel or gas fuel type. It is evident that the original model with horsepower, engine size and width is better. However, he wonders: horsepower, engine size, and width are treated independently.


Data Science Simplified Part 7: Log-Log Regression Models

So does it mean for linear regression models? Hypothesis testing discussed the concept of NULL and alternate hypothesis. Simple linear regression models made regression simple. So far the regression models built had only numeric independent variables.


Data Science Simplified Part 6: Model Selection Methods

The adjusted r-squared is the chosen evaluation metrics for multivariate linear regression models. Imagine that there are 100 variables; the number of models created based on the forward stepwise method is 100 * 101/2 1 i.e. The model will estimate price using engine size, horse power, and width of the car. Fernando tests the model performance on test data set.

This will typically learn in 100 epochs fairly good recommendations for movies. Companies are starting to offer hardware that can be situated close to the data production (in terms of network speed) for machine learning. It is for this reason that companies are starting to offer hardware that can be situated close to the data production (in terms of network speed) for machine learning. To get an idea of its speed, a researcher loaded up the Imagenet 2012 dataset and trained a Resnet50 machine learning model on the dataset.
