2. Introduction
Machine Learning (ML), a subset of Artificial Intelligence
(AI), is transforming the way machines interact with our
world.
Artificial Intelligence:
Broad term for machines
mimicking human
intelligence.
Machine Learning: Subset
of AI, machines learn from
data.

Learning (DL)
Key Concepts in Machine Learning
Datasets Data fuels machine learning. A dataset is a
collection of data points used to train and test ML
models, impacting system performance.
Algorithms Sets of rules machines use to learn from
data. Types include Linear Regression, Decision Trees,
Neural Networks, etc.
Training and Testing Training: Feeding data to analyze
and learn. Testing: Evaluating performance on
separate, unseen data.

3. How Machines Learn? – 7 Steps To Make
Machines Learn From the Data
Data Collection - Foundation of ML. Quality data is
crucial for accurate model working.
1.
Data Preparation - Combining, randomizing, cleaning,
and visualizing data. Dividing into training and testing
sets.
2.
Model Selection - Choosing ML model based on task
and data type (numerical or categorical).
3.
Training the Model - Feeding prepared data into the
model to discern patterns and make predictions.
4.
Model Evaluation - Assessing model performance
using separate, unseen testing data.
5.
Key Concepts in Machine Learning
Healthcare Predicting early disease detection,
personalized treatment plans, drug discovery, and
genomics.
Finance Fraud detection, algorithmic trading, and
improved credit scoring using ML.
Consumer Technology ML powers voice
assistants, personalized content feeds, intelligent
home devices, and enhances user experience.

4. Conclusion
Machine Learning is crucial in various sectors, offering
benefits in healthcare, finance, and consumer tech.
Despite its advantages, challenges like data quality,
privacy concerns, and the complex nature of models
need careful consideration. technology.
