It can be considered in some situations to be unsupervised machine learning.

Take the case of an autoregressive model for which the input is the value at time t-1 and the value to predict is the value at time t. You have an unsupervised learning problem here, because the input is the same as the output like if you had an X with no Y such that the Y is the next value of X.

However, this way of thinking is stretched a lot and I'd be cautious about using the word "unsupervised learning" for a simple linear regression.

The fact is that some unsupervised learning problems can be learned through a supervised learning way of thinking. So a linear regression will always be a supervised learning algorithm, but it can be used to achieve unsupervised learning.
