Syllabus

1️⃣ Essential AI Knowledge (38%)

AI vs ML vs DL (AMDA)

AI

Machine simulating human intelligence and decision-making

• Example: Alexa, Siri, Self-driving car, Chatbot

Machine Learning (ML)

Ability of machine to learn without explicitly being programmed.

• Example: Spam detection, Fraud detection, Recommendation systems

Deep Learning (DL)

Ability of machines to process data in a way that is inspired by the human brain (by using artificial neural network)

• Focuses on utilizing multilayered neural networks to perform tasks such as classification, regression, and representation learning.
• Derives rules from the data itself, rather than relying on explicit programming.
• Example: Image recognition, Natural language processing, Speech recognition

Generative AI

Subset of DL that focuses on create new data that is similar to the data that was used to train the model.

• Example: ChatGPT, DALL-E, Stable Diffusion

AgenticAI

Subset of generative AI focused on autonomous decision-making and actions

• Example: Autonomous robots, AI agents, Self-driving cars

PhysicalAI

AI integrated with physical systems (IoT, robotics)

• Example: Smart home devices, Industrial automation, Autonomous drones

Training vs Inference

AI Workflow:

 Data Preperation 
  |--> Model Training 
     |--> Optimization 
         |--> Inference/Deployment

Training	Inference
Model learning	Model usage
High compute + memory	Lower latency focus
Batch workloads	Real-time workloads
Multi-GPU scaling	Edge + cloud deployment

Training = compute intensive
Inference = latency optimized
