Artificial Intelligence

1. Foundational AI Concepts

Summary of AI Foundations

Cue Words	Notes
Define Artificial Intelligence, its current status, and key technological enablers.	Artificial Intelligence (AI): The ability of machines to simulate human cognitive functions, such as perceiving, natural language understanding, learning, reasoning, and problem-solving. Current Status: Primarily Narrow AI (Weak AI), which is intelligent only within specific contexts. Key Enablers: Massive increases in computational power (e.g., TPUs/GPUs) and the availability of Big Data.
Differentiate between Narrow AI, AGI, and Superintelligence.	Narrow AI (Weak AI): Designed for highly specific tasks (e.g., AlphaGo, Siri, recommendation engines). Cannot generalize outside its programmed domain. Artificial General Intelligence (AGI): Human-level intelligence across a wide range of cognitive tasks. Currently a technological frontier, not yet achieved. Superintelligence: A theoretical future state where machine intelligence far surpasses human capabilities across all domains. Represents a long-term existential risk.

AI Approaches & Key Technologies

Cue Words	Notes
Compare Rule-based Systems and Machine Learning (ML) approaches.	Rule-based Systems: Rely on human-encoded rules and logic (e.g., Deep Blue chess computer). Transparent and predictable, but fail in complex, dynamic, or uncertain scenarios. Machine Learning (ML): Uses statistical algorithms to learn patterns and make predictions directly from large datasets. Generative AI: A sub-field of ML capable of creating original content (text, images, code, video) (e.g., ChatGPT, Gemini, DALL-E).
Detail the key technology areas within the AI landscape.	Computer Vision: Interpreting and analyzing visual data (e.g., facial recognition, autonomous driving). Natural Language Processing (NLP): Comprehending and generating human language (e.g., machine translation, virtual assistants). Speech Recognition: Converting spoken language into structured text. Robotics: Combining AI with physical systems for autonomous movement and action. Predictive Analytics: Forecasting future trends based on historical data patterns (e.g., weather, fraud detection).

1a. AI vs ML vs Deep Learning vs Generative AI (Hierarchy)

The Nested Hierarchy & Types of Machine Learning

Cue Words	Notes
Explain the nested hierarchy: AI contains ML, which contains Deep Learning, which contains Generative AI.	Artificial Intelligence (AI): The broadest field — any technique enabling machines to mimic human intelligence (includes rule-based/symbolic AI, not just learning-based systems). Machine Learning (ML): A subset of AI where systems learn patterns from data statistically, without being explicitly programmed with rules. Deep Learning (DL): A subset of ML that uses multi-layered artificial neural networks (loosely modeled on the brain) to automatically extract features from raw, unstructured data (images, audio, text). Generative AI: A subset of DL (using architectures like Transformers, GANs, VAEs) focused specifically on creating new content rather than just classifying/predicting on existing data. Confused-pair alert: AI ⊃ ML ⊃ DL ⊃ Generative AI — every Generative AI system is Deep Learning, but not every Deep Learning system is generative (e.g., an image-classifying CNN is DL but not generative).
Differentiate Supervised, Unsupervised, and Reinforcement Learning.	Types of Machine Learning: Supervised Learning: Trained on labeled data (input-output pairs); used for classification and regression (e.g., spam detection). Unsupervised Learning: Finds hidden patterns/clusters in unlabeled data (e.g., customer segmentation). Reinforcement Learning: An agent learns via trial-and-error by receiving rewards/penalties for actions in an environment (e.g., AlphaGo, robotics control). Semi-Supervised Learning: Uses a small amount of labeled data combined with a large amount of unlabeled data.
What is a Large Language Model (LLM) and what architecture underpins most modern Generative AI?	Large Language Model (LLM): A Generative AI model trained on massive text corpora to predict and generate human-like language (e.g., GPT, Gemini, LLaMA, Bharat Gen). Transformer Architecture: Introduced by Google (2017, "Attention Is All You Need"); uses a self-attention mechanism to weigh the relevance of different words in a sequence, enabling parallel processing and underpinning virtually all modern LLMs.

2. Sectoral Applications & Major Concerns

Core AI Concerns

Cue Words	Notes
Explain AI Hallucinations and the demographic error rates in facial recognition.	Hallucinations: A phenomenon where Generative AI models generate false, nonsensical, or incorrect information but present it with high confidence as fact. Demographic Bias: Facial recognition models exhibit significantly higher error rates when identifying female and non-white demographics due to skewed training data.
Define the 'Black Box' problem in AI systems.	Black Box Problem: The lack of explainability (difficulty tracing how deep learning models arrive at specific decisions) and transparency (proprietary datasets and algorithms kept hidden from the public).
How does AI training clash with Privacy and Intellectual Property (IPR) laws?	Privacy: Conflict between the data minimization principle of privacy laws (e.g., DPDP Act) and AI's massive data consumption needs. IPR: Fair use debate regarding scraping copyrighted original works to train LLMs, and legal ambiguity over whether AI-generated content can be copyrighted.
What is the projected impact of AI on labor and employment?	Labor Disruption: Automation of non-routine, creative, and analytical tasks. It threatens clerical, writing, and coding jobs, while simultaneously creating new roles in AI safety, prompt engineering, and data curation.

3. Regulation & Global Frameworks

The Summit's intellectual framework was based on three foundational Sutras: People, Planning, and Progress. 2. The Preamble of the Summit stresses Democratising AI Resources, which acknowledges the Charter for Democratic Diffusion of AI as a binding framework to support locally relevant innovation and strengthen resilient AI ecosystems while respecting national laws. 3. The New Delhi Declaration on AI Impact was structured around seven Access Chakras (Pillars), which included Correct Answer: (D) Key Concepts & Explanation: The AI Impact Summit 2026, held in New Delhi, focused on shaping the future direction of artificial intelligence through an inclusive and development-oriented approach. The summit adopted an intellectual framework based on three guiding Sutras — People, Planet, and Prosperity. It also emphasized the democratization of AI resources and introduced the New Delhi Declaration on AI Impact, which was organized around seven thematic Chakras or pillars addressing key areas of AI development and governance. The summit framework was built around the three guiding principles of People, Planet, and Prosperity rather than People, Planning, and Progress. Hence, statement 1 is not correct. While the preamble emphasizes the democratization of AI resources, the Charter for Democratic Diffusion of AI was envisaged as a voluntary and non-binding framework rather than a legally binding arrangement. Hence, statement is incorrect.
