Correct Answer: A

Embedded AI represents the integration of artificial intelligence algorithms directly into microcontrollers or local hardware to execute tasks in real-time.

Correct Answer: C

ChatGPT is a prominent generative AI chatbot utilized extensively inside adaptive education applications to answer student queries, generate learning material, and explain concepts.

Correct Answer: B

ChatGPT was developed using Reinforcement Learning from Human Feedback (RLHF) to optimize its conversational responses and follow user instructions safely.

Correct Answer: A

Supervised learning requires labeled training datasets, while unsupervised learning operates on unlabeled data to discover hidden patterns or groupings.

Correct Answer: C

Large Language Models (LLMs) such as GPT-4 are built on decoder-only or decoder-based Transformer neural network architectures optimized for predicting subsequent text tokens.

Correct Answer: B

A validation set is used during machine learning model training to tune hyperparameters, check performance, and prevent overfitting.

Correct Answer: C

AI chatbots are primarily constructed using Natural Language Processing (NLP) techniques, which enable systems to parse, comprehend, and generate human-like sentences.

Correct Answer: A

Copilot is an AI-powered assistant developed by Microsoft, which integrates across various tools including Windows, Office, and Edge.

Correct Answer: D

PyTorch, TensorFlow, and Keras are popular deep learning coding frameworks, whereas MySQL is an SQL-based relational database.

Correct Answer: C

Apache Hadoop is an open-source big data framework designed for distributed storage and processing of massive datasets across computing clusters.

Correct Answer: D

BERT stands for Bidirectional Encoder Representations from Transformers, an advanced NLP model developed by Google to understand sentence context from both directions.

Correct Answer: D

Important AI and machine learning techniques comprise diverse learning families, including Supervised Learning (SL), Unsupervised Learning (UL), and Reinforcement Learning (RL).

Correct Answer: A

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a network to identify it and allow routing.

Correct Answer: D

Network topologies describe how network nodes and links are physically or logically arranged, with common models being Bus, Star, Ring, and Mesh.

Correct Answer: A

The groundbreaking 2017 research paper from Google titled "Attention Is All You Need" introduced the Transformer architecture, which replaced RNNs and LSTMs.

Correct Answer: B

The self-attention mechanism, which enables models to dynamically weigh relationships between tokens regardless of distance, was introduced by the Transformer.

Correct Answer: A

A heuristic is an approximate search technique or rule-of-thumb that directs problem-solving toward quick, optimal solutions rather than guarantees.

Correct Answer: B

Principal Component Analysis (PCA) is an unsupervised mathematical technique used to reduce the dimensionality of large datasets while preserving maximum variance.

Correct Answer: C

In reinforcement learning (RL), the "Agent" represents the active entity that perceives the environment, performs actions, and learns from rewards or penalties.
