Question & Answers
1. What is Artificial Intelligence (AI)?
Show Answer
2. What are the three domains of AI? Briefly describe them.
Show Answer
| Domain | Description | Type of Data |
|---|---|---|
| Computer Vision (CV) | Enables machines to interpret and understand visual information. | Images and videos |
| Natural Language Processing (NLP) | Enables machines to comprehend, generate and manipulate human language. | Text and human language |
| Statistical Data | Uses statistical techniques to analyse, interpret and draw insights from numerical or tabular data. | Numerical and tabular data |
3. Explain any three applications of AI.
Show Answer
1. Face Lock in Smartphones: The front camera detects and captures a person's face and stores its features. Later, the phone compares the captured face with the stored features and unlocks the phone when they match.
2. Smart Assistants: Smart assistants such as Siri and Alexa recognise patterns in speech, understand their meaning and provide useful responses.
3. Fraud and Risk Detection: Banking and finance companies can analyse customer profiles, past expenditures and other data to estimate the probability of financial risk and loan default.
4. Name and explain any three games related with the three domains of AI.
Show Answer
1. Rock, Paper and Scissors – Data for AI / Statistical Data: The machine tries to predict the player's next move by learning from the player's previous moves.
2. Semantris – Natural Language Processing (NLP): It is a word-association game. The AI looks at the words in play and chooses the words it thinks are most closely related to the clue entered by the player.
3. Quick, Draw! – Computer Vision (CV): The player draws an object or idea, and AI uses a neural network to guess what the drawing represents.
5. How does a machine become intelligent?
Show Answer
Answer: A machine becomes artificially intelligent when it can collect data, understand it, analyse it, learn from it and improve its performance. AI algorithms or models are developed and trained using data so that the machine can produce intelligent outputs.
6. Can you list down a few applications in your smartphone that widely make use of Computer Vision?
Show Answer
7. Draw out the difference between the three domains of AI with respect to the types of data they use.
Show Answer
| AI Domain | Data Used |
|---|---|
| Computer Vision (CV) | Images and videos |
| Natural Language Processing (NLP) | Text and human language |
| Statistical Data | Numerical and tabular data |
8. Identify the features and the domain of AI used in the following applications shown in the exercise images: (a), (b) and (c).
Show Answer
(a) Online shopping/product recommendation: AI analyses user and product data to recommend products. Domain: Statistical Data.
(b) Self-driving/autonomous car: AI uses cameras and visual information to understand the surroundings and assist in driving. Domain: Computer Vision.
(c) Voice/speech assistant: AI understands spoken language and responds to the user. Domain: Natural Language Processing.
9. Separate the following areas based on the kinds of AI domains widely used in them: Crop productivity, Traffic regulation, Maps and navigation, Text editors and autocorrect, Identifying and predicting disease.
Show Answer
| AI Domain | Areas |
|---|---|
| Statistical Data | Crop productivity; Maps and navigation; Identifying and predicting disease |
| Computer Vision (CV) | Traffic regulation |
| Natural Language Processing (NLP) | Text editors and autocorrect |
10. After the pandemic, it has been essential for everyone to wear a mask. However, you see many people not wearing masks in public places. Which domain of AI can be used to build a system to detect people not wearing masks?
Show Answer
11. Search for an online game that recognizes the image drawn by you. Write down the observations including the AI domain used by it.
Show Answer
Answer: Quick, Draw! is an online game in which the player draws an object or idea and AI tries to guess what has been drawn.
Observation: The AI can recognise drawings even when different people draw the same object in different ways.
AI Domain: Computer Vision (CV).
