Data preparation and cleaning in AI and Machine Learning projects involves making the collected data suitable for analysis. Details of this step include:

Data Review: Examine the collected data and consider the information it contains. Evaluate factors such as data structure, format, and missing values.

Data Cleaning: Identify and correct missing or erroneous data. Remove duplicate records and fix data inconsistencies.

Data Transformation: Convert data into a format suitable for analysis. Especially convert categorical data into numerical format and apply normalization steps.

Feature Engineering: Create new features or reorganize existing features to make the data more meaningful. Use feature selection strategies.

Data Splitting: Split the dataset into training, validation, and test sets. This will be used to evaluate the model's performance.

Data Quality Control: Recheck the quality of clean and prepared data. Once ready, proceed to analysis phase.

Feature Engineering

Extract or create suitable features for machine learning models. Prepare the dataset suitable for the model.

Feature engineering is an important step in AI and Machine Learning projects to make data more meaningful and usable. Details of this step include:

Feature Selection: Decide which data features to include in the model. Features are variables that provide data to the model and can affect outcomes.

Creating New Features: Use existing data to create new features. This can reveal hidden patterns or improve model performance.

Feature Engineering Operations: Apply transformations on features such as normalization or standardization. This ensures different features are on the same scale.

Transforming Categorical Data: Convert categorical data (e.g., color or category) into numerical values. This helps machine learning models to process these features.

Feature Selection Strategies: Consider different strategies when choosing features for the model. Feature selection impacts overall model performance.

Feature Visualization: Visualize relationships between features. This can ease understanding of the dataset and help identify important features.

Model Selection and Training
