OnlineSTL: Scaling Time Series Decomposition by 100x
Abhinav Mishra, Ram Sriharsha, Sichen Zhong
Decomposing a complex time series into trend, seasonality, and remainder components is an important primitive that facilitates time series anomaly detection, change point detection…
Efficient Algorithms for Estimating the Parameters of Mixed Linear Regression Models
Babak Barazandeh, Ali Ghafelebashi, Meisam Razaviyayn +1
Mixed linear regression (MLR) model is among the most exemplary statistical tools for modeling non-linear distributions using a mixture of linear models. When the additive noise in…
An Algorithm for Online K-Means Clustering
Edo Liberty, Ram Sriharsha, Maxim Sviridenko
This paper shows that one can be competitive with the k-means objective while operating online. In this model, the algorithm receives vectors v_1,...,v_n one by one in an arbitrary…
The moduli space of hyper-K{ä}hler four-fold compactifications
Ram Sriharsha
I discuss some aspects of the moduli space of hyper-K{ä}hler four-fold compactifications of type II and - theories. The dimension of the moduli space of these theories is…
Noncritical strings and W-algebras
Ram Sriharsha
Singularities of Spin(7) manifolds are considered in the worldsheet approach, and it is argued that the internal CFT describing a singular spin(7) has an enhanced ${\cal SW}({3\ove…
PP-Waves, M-Theory and Fluxes
Katrin Becker, Melanie Becker, Ram Sriharsha
We study a new type of warped compactifications of M-theory on eight manifolds for which nowhere vanishing covariantly constant spinors of indefinite chirality on the internal mani…
