A New Look at an Old Problem: A Universal Learning Approach to Linear Regression [article]

Koby Bibas, Yaniv Fogel, Meir Feder
2019 arXiv   pre-print
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.  ...

Numerical Approximation in CFD Problems Using Physics Informed Machine Learning [article]

Siddharth Rout, Vikas Dwivedi, Balaji Srinivasan
2021 arXiv   pre-print
The thesis focuses on various techniques to find an alternate approximation method that could be universally used for a wide range of CFD problems but with low computational cost and low runtime.  ...  Extreme learning machine (ELM) is a very fast neural network algorithm at the cost of tunable parameters. The ELM based variant of the proposed model is tested over the advection-diffusion problem.  ...  Addition of a new term 'Ax' helps the convergence by guiding the weights towards linear fitting at early stage of learning.  ...
