Matrices are essential in AI applications we use in daily life, from facial recognition
on smartphones to personalised recommendations on streaming platforms. How do you think the use of
matrices in AI helps improve the accuracy and efficiency of systems we interact with, such as virtual assistants,
online shopping, and healthcare applications?

Standard deviation is often used to measure the consistency of data, but in AI, how important is it for a machine
learning model to account for both low and high standard deviations? Can a model truly make accurate
predictions without understanding the variability in the data, or does focusing too much on standard deviation
limit its ability to adapt to real-world scenarios?
