Definition Flip

Define Artificial Intelligence (AI).

Answer Flip

AI is the simulation of human intelligence processes by computer systems. These processes include learning, reasoning, and self-correction.

Example: a self-driving car uses AI to navigate.
Key Concept Flip

Explain the concept of Machine Learning.

Answer Flip

Machine learning is a type of AI that allows systems to learn from data without being explicitly programmed.

Example: a spam filter learns to identify spam emails based on patterns in the emails it has already processed.
Definition Flip

Describe the structure and function of a neural network.

Answer Flip

A neural network is a computational model inspired by the structure of the human brain, consisting of interconnected nodes (neurons) organized in layers. It learns by adjusting the connections between these nodes.

Example: image recognition software might use a neural network.
Definition Flip

What is an expert system and how does it work?

Answer Flip

An expert system is a computer program that emulates the decision-making ability of a human expert. It uses a knowledge base and inference engine to provide advice or solutions.

Example: a medical diagnosis system.
Definition Flip

Explain the purpose of Natural Language Processing (NLP).

Answer Flip

NLP enables computers to understand, interpret, and generate human language. This allows interaction between humans and computers in a natural way.

Example: voice assistants such as Siri or Alexa use NLP.
Key Concept Flip

Describe how a chatbot uses AI.

Answer Flip

Chatbots use AI, particularly NLP and machine learning, to understand user input and provide relevant responses. They learn from previous conversations to improve their understanding. A common example is a customer service chatbot on a website.

Key Concept Flip

Give an example of a real-world application of AI in healthcare.

Answer Flip

AI is used in healthcare to analyze medical images (X-rays, MRIs) for faster and more accurate diagnoses. It can also assist in drug discovery and personalized treatment plans.

Example: AI is used to detect tumors in medical scans.
Key Concept Flip

Explain the difference between supervised and unsupervised learning.

Answer Flip

Supervised learning uses labeled data to train a model to predict outcomes. Unsupervised learning uses unlabeled data to find patterns and relationships. An example of supervised learning is classifying images, while unsupervised learning might be grouping customers based on purchasing behavior.

Key Concept Flip

Outline the potential ethical concerns related to the use of AI.

Answer Flip

Ethical concerns include job displacement due to automation, bias in algorithms leading to unfair outcomes, and privacy concerns related to data collection. It's important to consider these implications to ensure AI is used responsibly.
