3. Introduction to Machine Learning
Definition Training Data Human Involvement
Machine learning is a branch of
artificial intelligence that enables
systems to learn and improve from
experience without being
explicitly programmed. It involves
algorithms that learn from and
make predictions or decisions
based on data.
The machine learning process
begins with inputting training data
into the selected algorithm, which
can be known or unknown data to
train the model to make accurate
predictions.
Machines are trained by humans,
and human biases can be
incorporated into algorithms,
highlighting the importance of
ethical considerations in machine
learning.

4. Data Analysis
Learning Patterns
Minimal Human Intervention
Machine learning algorithms are trained to find relationships
and patterns in data, enabling them to make predictions,
classify data, and identify trends.
These algorithms learn patterns and relationships in the data
to make informed predictions, and they can be used to
identify and categorize different data types.
Machine learning involves minimal human intervention and
can be used for a wide range of tasks that involve data
analysis and prediction.

6. Supervised Learning
Definition Regression and
Classification
Real-world Applications
Supervised learning involves
training a model on a labeled
dataset, where the input data is
paired with the correct output.
The algorithm learns to make
predictions based on the input
data.
Supervised learning algorithms
can be used for regression tasks,
where the output is a continuous
value, and for classification tasks,
where the output is a category or
label.
Examples of supervised learning
applications, such as predicting
house prices based on features or
classifying emails as spam or non-
spam, will be discussed.

7. Clustering and Association
Anomaly Detection
Use Cases
Unsupervised learning algorithms are used to analyze and
cluster unlabeled data, identifying hidden patterns and
relationships. They can also be used for association rule
mining.
Unsupervised learning algorithms are effective in detecting
anomalies or outliers in data, which is valuable in fraud
detection and quality control.
Real-world examples of unsupervised learning, such as
customer segmentation and market basket analysis, will be
presented to showcase the practical applications of these
algorithms.
