Identify Categorical Features: First, look at your data and find the features that contain non-numerical values like text labels or categories (e.g., color, size, customer type). These are the features that need encoding. 2. Choose an Encoding Technique: There are different encoding methods...

PCA is also sensitive to outliers. Such data inputs could produce results that are very much off the correct projection of the data [6]. PCA presents limitations when it comes to interpretability. Since we’re transforming the data, features lose their original meaning. This could be problemati...
Views are temporary, and as soon as you delete them, you lose the filtered data. Here, when you work with Google Analytics, you should know two important terms: Dimensions vs Metrics Categorical variables, i.e., they are descriptive and not numeric. Think about names, colors, and more. ...
For example, if you’re clustering based on movie genres, a specialised measure might decide that “action” and “adventure” are closer to each other than “action” and “romance”. Ideally, the data for cluster analysis is categorical, interval or ordinal data. Using a mix of these ...
The deep model is a Dense Neural Network (DNN), a series of five hidden MLP layers of 1024 neurons, each beginning with a dense embedding of features. Categorical variables are embedded into continuous vector spaces before being fed to the DNN via learned or user-determined embeddings. What...
It is used when the dependent variable is binary or categorical. It models the probability of an event occurring by fitting a logistic function to the independent variables. The output is a probability score that can be used to classify instances into different classes. It is widely used in ...

One-hot encoding.This is the inverse of binning; it creates numerical features from categorical variables. One-hot encoding maps categorical features to binary representations, which are used to map the feature in a matrix or vector space. Literature often refers to this binary representation as a...
