Decision Tree is a supervised learning algorithm that builds a tree-like structure to make decisions based on input data.

Unsupervised learning aims to discover hidden patterns and structures in data without labeled examples.

K-Means Clustering is a widely used algorithm for partitioning data into a specified number of clusters.

Data mining aims to extract meaningful patterns and trends from large volumes of data.

Accuracy is a commonly used evaluation metric for classification models, measuring the proportion of correctly classified instances.

Feature selection aims to reduce the number of features, improve model interpretability, and prevent overfitting.

Imputation is a common technique for dealing with missing data, where missing values are estimated using various methods.

Tuning involves adjusting the hyperparameters of a machine learning model to optimize its performance.

Q-Learning is a reinforcement learning algorithm that learns optimal actions through interactions with the environment.

NLP aims to understand, interpret, and generate human language.

PCA, SVD, and LDA are all commonly used techniques for dimensionality reduction.

Cross-validation is used to evaluate model performance, prevent overfitting, and select the best model.

Bagging, Boosting, and Stacking are all common ensemble learning methods.

Recommender systems aim to predict user preferences, generate personalized recommendations, and improve user engagement.

CNN, RNN, and GAN are all common deep learning architectures.
