Introduction to AI
Artificial Intelligence (AI) is a branch of computer science that enables
machines to simulate human intelligence. It involves algorithms and
models that allow computers to learn, reason, solve problems, and
make decisions. AI includes technologies like machine learning, deep
learning, and natural language processing, enabling applications such
as chatbots, recommendation systems, and autonomous vehicles.
AI can be classified into Narrow AI (specialized tasks), General AI
(humanlike intelligence), and Super AI (beyond human capabilities). It is
widely used in healthcare, finance, robotics, and more, transforming
industries and daily life while raising ethical and societal concerns.
History and Evolution of AI
1 Early Foundations (Pre-1950s)
The idea of intelligent machines dates back to ancient myths and early
computing theories. Alan Turing proposed the Turing Test (1950) to
determine if a machine can exhibit human-like intelligence.
2 Birth of AI (1950s - 1960s)
John McCarthy coined the term "Artificial Intelligence" in 1956 at the
Dartmouth Conference. Early AI programs, such as Logic Theorist and
General Problem Solver, were developed. The first AI chatbot, ELIZA,
was created in the 1960s.
3 AI Winters (1970s - 1980s)
AI faced setbacks due to lack of computational power and funding
cuts. Despite this, expert systems (rule-based AI) became popular in
industries.

achieved breakthroughs in
computer vision, speech
recognition, and NLP.
3 Future of AI
Research on Artificial General
Intelligence (AGI) aims to develop
human-like AI. AI continues to
advance in fields like robotics,
healthcare, and automation,
raising ethical and societal
challenges.
Machine Learning vs Deep Learning vs AI
Artificial Intelligence (AI)
AI is the broad field of creating
machines that can perform tasks
requiring human intelligence. AI
includes various techniques such as
rule-based systems, expert systems,
machine learning, and deep learning.
Machine Learning (ML)
ML is a subset of AI that focuses on
developing algorithms that enable
machines to learn from data without
explicit programming. ML models
analyze input data, identify patterns,
and improve their performance over
time.
Deep Learning (DL)
DL is a specialized subset of ML that
uses artificial neural networks
inspired by the human brain. These
networks have multiple layers (deep
neural networks) that help process
vast amounts of unstructured data.
Neural Networks
What Are Neural Networks?
Neural Networks are a subset of Machine Learning, inspired by the
structure and function of the human brain. They consist of layers of
interconnected nodes (neurons) that process data and recognize
patterns.
Deep Learning
Neural networks are the foundation of Deep Learning and are
widely used in applications like image recognition, speech
processing, and AI-driven automation.
Structure of a Neural Network
Input Layer
The first layer that receives raw data (e.g., images, text, or numerical
inputs). Each neuron in this layer represents a feature of the input
data.
Hidden Layers
These layers perform computations and extract patterns. Each
neuron in a hidden layer applies a mathematical function (activation
function) to its input. More hidden layers create a Deep Neural
Network (DNN).
Output Layer
Produces the final prediction or classification result. The number of
neurons here depends on the problem (e.g., two neurons for binary
classification, multiple for multi-class tasks).
How Neural Networks Work
Forward Propagation
Input data passes through layers, and each neuron applies weights and
biases. The weighted sum is passed through an activation function to
introduce non-linearity. The final layer produces a prediction.
Loss Calculation & Optimization
Loss Calculation
The difference between the
predicted output and actual output
is calculated using a loss function.
1
Backpropagation &
Optimization
The network adjusts the weights
using Backpropagation, which
calculates how much each weight
contributed to the error.
2
Gradient Descent
Gradient Descent updates the
weights to minimize error. This cycle
repeats for multiple iterations until
the model learns effectively.

Natural Language Processing (NLP)
NLP Techniques
• Tokenization
• Stemming & lemmatization
• Sentiment analysis

Types of AI
Super AI
AI surpassing human intelligence in all aspects. Capable of independent thinking,
emotions, and decision-making. Currently hypothetical.
General AI (Strong AI)
Can perform any intellectual task like a human. Understands, learns,
and applies knowledge across different domains. Still theoretical.
Narrow AI (Weak AI)
Specialized in performing a specific task. Cannot generalize
beyond its programming. Examples: Siri, Google Assistant,
Chatbots.
