Automated Machine Learning (AutoML) refers to the process of automating the end-to-end process of applying machine learning to real-world problems, making it accessible to non-experts and improving efficiency for experts. It encompasses data preprocessing, model selection, hyperparameter tuning, and model evaluation to streamline the creation of machine learning models.

Data preprocessing is a crucial step in the data analysis pipeline that involves transforming raw data into a clean and usable format, ensuring that the data is ready for further analysis or machine learning models. This process enhances data quality by handling missing values, normalizing data, and reducing dimensionality, which ultimately improves the accuracy and efficiency of analytical models.

data preprocessing

Model selection is the process of choosing the most appropriate machine learning model from a set of candidates based on their performance on a given dataset. It involves balancing complexity and accuracy to avoid overfitting or underfitting, often using techniques like cross-validation to assess generalization capability.

model selection

Hyperparameter tuning is the process of optimizing the parameters that govern the learning process of a machine learning model, which are not learned from the data itself. Effective tuning can significantly improve model performance by finding the optimal combination of hyperparameters for a given task.

hyperparameter tuning

Model evaluation is a crucial step in the machine learning pipeline that involves assessing the performance of a predictive model using specific metrics to ensure its accuracy and generalizability. It helps in understanding the model's strengths and weaknesses, guiding improvements and ensuring that the model meets the desired objectives before deployment.
