Feedback
Think of this as a
teacher providing clear
examples
Similar to discovering patterns
or groups in new information
without explicit guidance
Receiving feedback from the
environment or others about the
consequences of actions, which
helps in adjusting behaviors.

6. How Computer Learn ?

7. The simple definition of
"Artificially intelligent" is
attempting to simulate human
intelligence, including aspects
that involve learning, which we
aim to replicate through Machine
Learning techniques.

10. UnSupervised Learning
Unsupervised learning is a type of machine
learning technique in which an algorithm
discovers patterns and relationships using
unlabeled data.
The primary goal of Unsupervised learning is often
to discover hidden patterns, similarities, or
clusters within the data which can help in data
exploration, visualization, dimensionality
reduction, and more

11. Clustering
The process of grouping data points into
clusters based on their similarity. This
technique is useful for identifying patterns
and relationships in data without the need
for labeled examples
Algorithms: K-means, Mean-shift..etc.
One main category of UnSupervised Learning

12. Supervised Learning
Supervised learning is defined as when a model
gets trained on a “Labelled Dataset”. Labelled
datasets have both input (X) and output
parameters (Y). In Supervised Learning,
algorithms learn to map points between inputs
and correct outputs.
Supervised Learning models have a baseline
understanding of what the correct output values
should be

13. Two main categories of Supervised Learning
Classification Regression
Deals with predicting categorical target
variables, which represent discrete
classes or labels. For instance, classifying
emails as spam or not spam, or
predicting whether a patient has a high
risk of heart disease.
Algorithms: Logistic Regression, SVM,
Decision Tree, KNN..etc
Deals with predicting continuous target
variables, which represent numerical
values. For example, predicting the
price of a house based on its size and
location, or forecasting the sales of a
product.
Algorithms: Linear Regression, Ridge
Regression, Lasso Regression..etc

14. In Conclusion, The key difference between supervised and unsupervised
Learning is the Type of data used, whether it’s Labelled or not
Here, the data is
labeled, so what we
did is draw the line
to separate the
classes from one
another
On the other hand,
the data isn’t labeled
so we’re grouping
similar points
together, based on its
attributes/features

32. What is gradient descent?
Gradient Descent is an optimization algorithm
used in machine learning to minimize the cost
function (or error) by iteratively adjusting the
model's parameters
It works by calculating the gradient (slope) of the
cost function with respect to the parameters and
then moving the parameters in the opposite
direction of the gradient to reduce the error. The
process continues until the model reaches the
lowest possible error.

33. it's like walking down a hill (the cost function)
to find the lowest point (the optimal solution)
by taking small steps in the direction that
decreases the slope the most.
In Simple Terms

34. Recap

35. Instruction
For instance, a student learns math by solving
problems with provided solutions to check
correctness.
Machine Learning Model is trained on a dataset
that includes input-output pairs, where the
correct output for each input is provided. This
process is similar to how a student learns math
problems with provided solutions

36. student exploring different types of plants
and identifying common characteristics
without prior knowledge.
Machine Learning Model produces clusters
or groupings of plants that share similar
characteristics. Each cluster represents a
group of plants with common features.
Experience & Practice

37. •A student starts at a new school and needs
to find their way to various locations like
classrooms, the cafeteria.
Machine Learning Model learns to
navigate the school (environment) by
exploring different routes (actions) and
receiving feedback (rewards) based on
their performance.

Use Case: Remote patient monitoring

Model Using LDR Readings
In this task, we aim to develop a machine learning model that utilizes pre-
collected Infrared sensor (IR) readings to predict the distance in cm. The steps
involved include:
Data Preprocessing:
1.
Utilize the provided CSV file containing IR analog signal data (ranging from
0 to 4095) and preprocess it for training the model.
Model Training:
2.
Design and train a simple neural network using a Jupyter Notebook (.ipynb
file). The model will learn the relationship between the input readings and
the corresponding lighting conditions.
Deployment on ESP32:
3.
After training, the model will be converted and deployed onto an ESP32
microcontroller. The ESP32 will use the model to take real-time IR readings
and transform it into distance in cm.

They introduce non-linearity into the model,
allowing it to learn and represent complex
