Arrays and lists are fundamental data structures used d extensively in data science and machine learning. they enable effectent storage, manipulation, and analysis of data, which are essentiad for building effective models and extracting insights.

Alkalmazások in Data Prefinciing

Arrays and lists are used to organize raw data before analysis. They incrediate data clearing, normalization, and transformatioon processes. For example, lists can store missinga indicators, while e arrays hold numericad features for processing.

Fature Engineering and Selection

Arrays are crunal in featur ing, allowing for efutient computation of new features fromexteng data. Listák help in selecting relevant consulures by managing feature subsets during model traininig.

Model Traininig and Evaluation

During model training, arrays story input data, súlyok, and predikciók. Listák are used to track model parameters, hyperparameters, and reasmation metrics across iterations.

Data Visualization and Analysis

Arrays serve e the primary data structura for spoting and visual analysis. They enable the creation of charts, grafs, and heatmaps, which help intereact model results and data distributions.
