🤖 Introduction to Machine Learning: Fundamentals & Key Concepts

Machine Learning (ML) is revolutionizing industries, from healthcare to finance, by enabling computers to learn from data and make intelligent decisions. If you’re new to ML, this guide will break down its fundamentals and key concepts to get you started!

🎯 What is Machine Learning?Machine Learning is a subset of Artificial Intelligence (AI) that enables computers to learn patterns from data and make predictions without explicit programming.
👉 Example: Netflix recommending movies based on your viewing history. 🎬

📌 Types of Machine LearningML is categorized into three main types:
🔹 1. Supervised LearningThe model learns from labeled data, where input-output pairs are provided.
Example: Predicting house prices based on features like size and location.

from sklearn.linear_model import LinearRegression
import numpy as np

X = np.array([[1000], [1500], [2000]])  # Square feet
y = np.array([150000, 200000, 250000])  # House prices

model = LinearRegression()
model.fit(X, y)
prediction = model.predict([[1800]])
print(prediction)  # Predicted price

🔹 2. Unsupervised LearningThe model finds patterns in data without labeled outcomes.
Example: Customer segmentation in marketing.
🔹 3. Reinforcement LearningThe model learns through rewards and penalties to take optimal actions.
Example: Self-driving cars learning to navigate.

🛠 Key Machine Learning Concepts

🔹 Features & Labels

Features = Input data (e.g., Age, Salary)
Labels = Expected output (e.g., Will a customer buy a product?)

🔹 Training & Testing

Training = Teaching the model using data
Testing = Evaluating the model’s performance

🔹 Overfitting & Underfitting

Overfitting = Model memorizes data but fails on new data
Underfitting = Model is too simple and misses patterns
