What is the difference between artificial intelligence and machine learning?

An “intelligent” computer uses AI to think like a human and perform tasks on its own. Machine learning is how a computer system develops its intelligence. One way to train a computer to mimic human reasoning is to use a neural network, which is a series of algorithms that are modeled after the human brain.

What is unsupervised learning method?

Unsupervised learning, also known as unsupervised machine learning, uses machine learning algorithms to analyze and cluster unlabeled datasets. These algorithms discover hidden patterns or data groupings without the need for human intervention.

What is variance in deep learning?

Variance refers to the changes in the model when using different portions of the training data set. Simply stated, variance is the variability in the model prediction—how much the ML function can adjust depending on the given data set. Variance comes from highly complex models with a large number of features.

What is difference between classification and regression?

Classification is the task of predicting a discrete class label. Regression is the task of predicting a continuous quantity.

How hard is machine learning?

Factors that make machine learning difficult are the in-depth knowledge of many aspects of mathematics and computer science and the attention to detail one must take in identifying inefficiencies in the algorithm. Machine learning applications also require meticulous attention to optimize an algorithm.
