The Phase Transition in Online PCA Depends on , not
Apratim Dey
High dimensional statistical theory has established the importance of constant aspect ratio, when the number of dimensions () and samples () satisfy with $n/d\…
Optimal Vector Compressed Sensing Using James Stein Shrinkage
Apratim Dey, David Donoho
The trend in modern science and technology is to take vector measurements rather than scalars, ruthlessly scaling to ever higher dimensional vectors. For about two decades now, tra…
Universality of the Pathway in Avoiding Model Collapse
Apratim Dey, David Donoho
Researchers in empirical machine learning recently spotlighted their fears of so-called Model Collapse. They imagined a discard workflow, where an initial generative model is train…
Collapse or Thrive? Perils and Promises of Synthetic Data in a Self-Generating World
Joshua Kazdan, Rylan Schaeffer, Apratim Dey +4
What happens when generative machine learning models are pretrained on web-scale datasets containing data generated by earlier models? Some prior work warns of "model collapse" as…
Is Model Collapse Inevitable? Breaking the Curse of Recursion by Accumulating Real and Synthetic Data
Matthias Gerstgrasser, Rylan Schaeffer, Apratim Dey +11
The proliferation of generative models, combined with pretraining on web-scale data, raises a timely question: what happens when these models are trained on their own generated out…
Inferring the redshift of more than 150 GRBs with a Machine Learning Ensemble model
Maria Giovanna Dainotti, Elias Taira, Eric Wang +8
Gamma-Ray Bursts (GRBs), due to their high luminosities are detected up to redshift 10, and thus have the potential to be vital cosmological probes of early processes in the univer…
