Machine Learning (ML) is a branch of artificial intelligence (AI)
that enables computers to learn patterns from data and make
predictions or decisions without being explicitly programmed.
TYPES OF ML
1. Supervised Learning:
- Learns from labeled data (input-output pairs).
- Used for classification (e.g., spam detection) and regression (e.g., house price prediction).
2. Unsupervised Learning:
- Finds patterns in unlabeled data.
- Used for clustering (e.g., customer segmentation) and dimensionality reduction (e.g., PCA).
3. Semi-Supervised Learning:
- Uses a small amount of labeled data with a large amount of unlabeled data.
- Example: Image recognition with limited annotations.
4. Reinforcement Learning:
- Learns by interacting with an environment and receiving rewards.
- Example: Game AI, robotics, self-driving cars.

• Data Dependence: ML systems require large amounts of data
to function effectively, which can be difficult to collect,
expensive to store, and raise privacy concerns.
• Bias and Fairness: If the data used to train ML is biased, the
model will reflect and amplify those biases, leading to unfair
outcomes.
• Example: Facial recognition algorithms have been shown
to perform poorly on minority groups, leading to concerns
about their use in law enforcement.
26 ETHICAL CONCERNS
• Bias in ML : ML systems can perpetuate biases present in their
training data, leading to discriminatory outcomes (e.g., biased
hiring algorithms).
• Transparency : Many ML algorithms are "black boxes," making
it difficult to understand how they arrive at decisions. This lack of
transparency can pose problems, especially in high-stakes
applications like healthcare and criminal justice.
• Privacy : ML systems often rely on vast amounts of personal
data, raising concerns about how this data is collected, used,
and protected.
