AI with Matlab 2025

Which of the following statements is TRUE about the relationship between AI, ML and DL?

• Artificial intelligence is a subset of deep learning
• Machine learning is a subset of deep learning
• Deep learning is a subset of machine learning
• Deep learning has nothing to do with AI

Answer explanation

Deep learning is a sub-category of machine learning, which in turn is a field of artificial intelligence.

Which of the following is not a common application of Artificial Intelligence?

• Solving linear equations
• Image recognition
• Natural language processing
• Autonomous vehicles

Answer explanation

Solving linear equations is a standard numerical method, not an AI application.

In a feedforward (simple) neural network, what do the ‘weights’ represent?

• Classification Labels
• input values
• Parameters that determine the importance of signals between neurons
• Final outputs of the network

Answer explanation

Weights determine how much an input affects a neuron's output and are crucial for learning.

Which type of learning involves labeled data?

• Unsupervised learning
• Supervised learning
• Reinforcement learning

Answer explanation

Supervised learning uses labeled input-output pairs to train models.

• dlarray
• structure
• table
• cell

Answer explanation

dlarray is a special tensor made in matlab for ML

• Connect
• Forward
• Predict
• Train

What do you need to use in MATLAB to compute the derivative of a loss function f(x) with respect to a dlarray?

• trainNetwork
• gradient
• backward
• dlgradient

What does PINN stands for?

• Phisics informed Neural Network
• Proportional Integrative Nerual Network
• Piecewise Neural Network

How to reduce the problems of unbalanced dataset?

• SfotMax
• Oversample/Undersample
• Model Based Design
• Custom layers

Which kind of neural network is usually the best for signal regression problem?
