A New Look at an Old Problem: A Universal Learning Approach to Linear Regression
[article]
2019
arXiv
pre-print
Preserved Fulltext
Linear regression is a classical paradigm in statistics. A new look at it is provided via the lens of universal learning. ...
In applying universal learning to linear regression the hypotheses class represents the label y∈ R as a linear combination of the feature vector x^Tθ where x∈ R^M, within a Gaussian error. ...
This work provides a new view of this problem based on recent results in universal learning. ...
