Core Types of ML Training Techniques

1. Supervised Learning Training Techniques

Supervised learning is one of the most widely used machine learning training techniques. In this approach, models learn from labeled data. Therefore, each input is paired with a correct output.

Common supervised training methods include:

• Linear regression training
• Logistic regression optimization
• Support Vector Machine (SVM) training
• Decision tree learning
• Random forest training

Moreover, supervised training techniques are ideal for classification and regression tasks. However, they require high‑quality labeled datasets, which can be expensive to obtain.

2. Unsupervised Learning Training Techniques

Unsupervised learning training techniques work with unlabeled data. Instead of predefined outputs, models discover hidden patterns automatically. Consequently, these techniques are useful for exploratory data analysis.

Key unsupervised ML training methods include:

• K‑means clustering
• Hierarchical clustering
• Principal Component Analysis (PCA)
• Autoencoders
• Association rule learning

Furthermore, unsupervised training techniques are widely used in customer segmentation, anomaly detection, and dimensionality reduction. The Ultimate AI Prompts Guide for Beginners and Professionals

4. Reinforcement Learning Training Techniques

Reinforcement learning training techniques focus on learning through interaction with an environment. Instead of labeled data, models receive rewards or penalties based on actions.

Common reinforcement learning methods include:

• Q‑learning
• Deep Q Networks (DQN)
• Policy gradient methods
• Actor‑critic algorithms

Moreover, reinforcement learning training techniques are widely used in robotics, gaming, finance, and autonomous systems.
