Streaming Kernel Principal Component Analysis
Mina Ghashami, Daniel Perry, Jeff M. Phillips
Kernel principal component analysis (KPCA) provides a concise set of basis vectors which capture non-linear structures within large data sets, and is a central tool in data analysi…
Binary Coding in Stream
Mina Ghashami, Amirali Abdullah
Big data is becoming ever more ubiquitous, ranging over massive video repositories, document corpuses, image sets and Internet routing history. Proximity search and clustering are…
Improved Practical Matrix Sketching with Guarantees
Amey Desai, Mina Ghashami, Jeff M. Phillips
Matrices have become essential data representations for many large-scale problems in data analytics, and hence matrix sketching is a critical task. Although much research has focus…
Cosmology of bigravity with doubly coupled matter
Denis Comelli, Marco Crisostomi, Kazuya Koyama +2
We study cosmology in the bigravity formulation of the dRGT model where matter couples to both metrics. At linear order in perturbation theory two mass scales emerge: an hard one f…
