Introduction to Classification
=====================================
Classification is a fundamental concept in Artificial Intelligence (AI) and Machine Learning (ML) that involves categorizing data into predefined classes or labels. It's a type of supervised learning where the model is trained on labeled data to learn the relationships between input features and corresponding output labels.
What is Classification?
------------------------
Classification is the process of assigning a label or class to a new, unseen instance based on its features. The goal is to develop a model that can accurately predict the class label for a given input, allowing for informed decision-making or action.
Types of Classification
--------------------------
Binary Classification
In binary classification, t
0/1 (e.g., spam vs. non-spam emails)
Yes/No (e.g., credit approval vs. rejection)
Positive/Negative (e.g., medical diagnosis)
Binary classification is widely used in applications such as:
Sentiment analysis
Image classification
Credit risk assessment
Multi-Class Classification
In multi-class classification, t
Handwritten digit recognition (10 classes: 0-9)
Text classification (e.g., news articles into categories like sports, politics, etc.)
Product categorization (e.g., electronics, clothing, etc.)
Multi-class classification is commonly used in applications such as:
Natural Language Processing (NLP)
Computer Vision
Recommendation systems
