18a Artificial intelligence end unit and KEY TERMS

What is Dijkstra's algorithm used for?

• Creating artificial neural networks

• Sorting data in alphabetical order

• Finding the shortest path between two nodes in a graph

• Generating random numbers

What is the main difference between A* algorithm and Dijkstra's algorithm?

• Dijkstra's algorithm is used for unsupervised learning

• A* algorithm uses a heuristic approach for better performance

• Dijkstra's algorithm is faster than A* algorithm

• A* algorithm can only work on small graphs

What is the purpose of a web crawler?

• Creating chatbots for websites

• Systematically browsing the world wide web to update web page content

• Optimizing artificial neural networks

• Finding hidden patterns in data

What is the function of back propagation in artificial neural networks?

• Calculating error gradients to adjust node weightings

• Generating random data for training

• Optimizing regression models

• Interacting with users on websites

What is the definition of supervised learning?

• Predicting future outcomes based on past data with input and output values

• Identifying hidden patterns from input data

• Learning on the basis of reward and punishment

• Interactively querying source data to reach desired results

What is the main characteristic of deep learning?

• Systems are trained on the 'right' answer

• Machines think in a way similar to the human brain

• Machines learn without being programmed to learn

• Systems use both labelled and unlabelled data

What is the purpose of a chatbot?

• Optimizing artificial neural networks

• Finding the shortest route between nodes in a graph

• Simulating conversational interaction between humans and a website

• Identifying hidden patterns in data

What is the role of reinforcement learning?

• Predicting future outcomes based on past data

• Interactively querying source data to reach desired results

• Identifying hidden patterns from input data

• Learning on the basis of 'reward and punishment'
