Slot filling is a crucial component in task-oriented dialog systems that is
used to parse (user) utterances into semantic concepts called slots. An
ontology is defined by the collection of slots and the values that each slot
can take. The m...

Machine Learning
Markov chain Monte Carlo (MCMC) algorithms for hidden Markov models often
rely on the forward-backward sampler. This makes them computationally slow as
the length of the time series increases, motivating the development of
sub-sampling-base...

Functional Analysis
The bicomplex Bergman spaces are studied for any bounded bicomplex domain.
Its Bergman kernel is computed in terms of the kernels of the complex
projections of the domain. We also introduce two additional reproducing kernel
Hilbert spaces a...

Semantic segmentation for aerial imagery is a challenging and important
problem in remotely sensed imagery analysis. In recent years, with the success
of deep learning, various convolutional neural network (CNN) based models have
been devel...

An exceptionally simple model of ball lightning is proposed that describes it
as a highly charged sphere of hot, conductive, air surrounded by colder air.
This conductive sphere possesses a net excess of charge. This charge will
create a co...

We study the index of N=4 Yang-Mills theory on
S3×R at large angular momenta. A generalized Cardy limit
exhibits macroscopic entropy at large N. Our result is derived using free QFT
analysis, and also a backgr...

We show that the cohomology of canonical extensions of automorphic vector
bundles over toroidal compactifications of Shimura varieties can be computed by
relative Lie algebra cohomology of automorphic forms. Our result is inspired by

We prove a version of the tamely ramified geometric Langlands correspondence
in positive characteristic for GLn(k). Let k be an algebraically closed
field of characteristic p>n. Let X be a smooth projective curve over k
