Machine Learning is generally divided into three main categories:

  1. Supervised Learning: This type of learning uses labeled data. It is used to predict outcomes based on input data. For instance, predicting house prices based on historical data of various factors like size, location, and number of bedrooms.

  2. Unsupervised Learning: Unlike supervised learning, unsupervised learning works with unlabeled data. The algorithm tries to group similar items together. A common example is customer segmentation in marketing, where customers are grouped based on purchasing behavior without predefined labels.

  3. Reinforcement Learning: In this type, an agent learns to make decisions by taking actions in an environment to maximize cumulative rewards. A popular example would be training a robot to navigate a maze.

What is Deep Learning?

The Basics

Deep Learning is a specialized subfield of Machine Learning that uses neural networks with many layers (hence “deep”). It mimics the human brain’s operation to process data, making it capable of handling large volumes and high-dimensional data, such as images, text, and voice.

A classic example is image recognition. A deep learning model can be trained to recognize various objects in pictures. For instance, when trained on thousands of dog images, a deep learning model can learn to identify dogs in new images.

Neural Networks Explained

A neural network consists of interconnected nodes (neurons) that process information. Each layer extracts features from the input data, and the output layer provides the final prediction. The more layers present, the more complex the features the model can learn, making deep learning particularly powerful for complex tasks like natural language processing and computer vision.

Key Differences Between Machine Learning and Deep Learning

Complexity and Data Requirements

Machine Learning models often work well with smaller datasets and simpler patterns. They require more feature engineering to extract meaningful data. In contrast, Deep Learning models are data-hungry, usually needing vast amounts of data to function effectively.

Interpretability

Machine Learning models, such as decision trees or linear regression, are generally more interpretable than Deep Learning models. In healthcare, for example, it is essential to explain predictions. A model stating, “This patient might have diabetes due to high blood sugar levels,” is more interpretable than a neural network’s opaque decision-making process.

Training Time

Training a traditional Machine Learning model can take minutes to a few hours depending on the complexity and data size. On the other hand, training a Deep Learning model can require extensive computational power and time—often days or even weeks—due to its layered approach.

Step 4: Split the Data

python
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

Step 5: Create and Train the Model

python
model = RandomForestClassifier(n_estimators=100)
model.fit(X_train, y_train)

Step 6: Make Predictions

python
predictions = model.predict(X_test)
