What is Machine Learning?
Machine Learning (ML) is a subset of AI that enables computers to learn from data without being explicitly programmed.
Key Characteristics of Machine Learning
- Works primarily with structured data.
- Requires feature engineering, meaning manual selection of important data points.
- Effective for predictive analytics and pattern recognition.
- Can be categorized into supervised, unsupervised, and reinforcement learning.
Examples of Machine Learning Applications
- Email Spam Filtering: ML models classify emails as spam or not spam.
- Fraud Detection: ML is used to identify fraudulent transactions in the Banks.
- Recommendation Systems: Platforms like Netflix, Amazon, and YouTube suggest content based on user behavior.
What is Deep Learning?
Deep Learning (DL) is a specialized subset of Machine Learning that uses artificial neural networks to simulate human brain processes. Unlike ML, deep learning can handle large amounts of unstructured data without extensive manual input.
Key Characteristics of Deep Learning
- Uses multi-layered neural networks (hence “deep”).
- Can process unstructured data such as images, text, audio, and video.
- Automatically learns important features without manual selection.
- Requires large datasets and substantial computational resources.
Examples of Deep Learning Applications
- Facial Recognition: Used in security systems and social media tagging.
- Autonomous Vehicles: Self-driving cars rely on deep learning models.
- Natural Language Processing (NLP): Voice assistants like Alexa and Siri use DL to process and understand human speech.
Machine Learning vs. Deep Learning: Key Differences
| Feature | Machine Learning | Deep Learning |
|---|---|---|
| Data Requirement | Works with small to medium datasets | Requires large datasets |
| Feature Engineering | Needs manual selection of features | Learns features automatically |
| Complexity | Less complex | Highly complex |
| Computational Power | Works on regular computers | Requires GPUs and powerful hardware |
| Training Time | Faster training | Requires longer training time |
| Interpretability | More interpretable | Often considered a “black box” |
How Do Machine Learning and Deep Learning Work?
How Machine Learning Works
- Data Collection: Gather structured data for training.

- Model Training: Train using algorithms like Decision Trees, Random Forest, or SVM.
- Evaluation & Prediction: Test the model and refine predictions.
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score
# Split data
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Train model
model = RandomForestClassifier()
model.fit(X_train, y_train)
# Predict
y_pred = model.predict(X_test)
# Evaluate
accuracy = accuracy_score(y_test, y_pred)
print(f'Model Accuracy: {accuracy*100:.2f}%')
How Deep Learning Works
- Data Collection: Gather large unstructured datasets.
