       | Huh, interesting.

       | According to the authors, these "parameteric matrix models" or
       | PMMs outperform:
       | 
       | * commonly used (zero- or low-parameter) regression models like
       | XGBoost, random forests, kNN, and support vector machines on a
       | variety of regression tasks, and
       | 
       | * DNNs with 10x to 100x more parameters on small-scale image
       | classification tasks like MNIST variants, CIFAR-10, and CIFAR-100
       | -- albeit with a lot of feature engineering.
       | 
       | It looks promising, but I cannot find a link to the authors' code
       | for replicating their experiments.

         | reviewed published version. If I remember, I'll come back to
         | this thread and post the link.

             | Of course - I'm glad to see people are interested. I look
             | forward to any feedback on our work either public or
             | private.

       | Looks like a cool idea and it could benefit from a more complete
       | and detailed illustration and explanation of the architecture.
       | 
       | Reads like the authors skip to implications before clarifying the
       | design.
       | 
       | Also, a stylistic sidenote, narrower columns of text are much
       | easier to read, newspapers and journals do this for good reason

         | First author here. I agree with your points, we were
         | constrained by the format and (especially) writing style
         | expected by the journal we're submitting to. The Methods
         | sections contain more explicit explanations as well as other
         | analyses.
