no code implementations28 Feb 2022 Jamie Haddock, Lara Kassab, Sixian Li, Alona Kryshchenko, Rachel Grotheer, Elena Sizikova, Chuntian Wang, Thomas Merkh, RWMA Madushani, Miju Ahn, Deanna Needell, Kathryn Leonard

We propose new semi-supervised nonnegative matrix factorization (SSNMF) models for document classification and provide motivation for these models as maximum likelihood estimators.

no code implementations3 Aug 2021 Kathlén Kohn, Thomas Merkh, Guido Montúfar, Matthew Trager

We study the family of functions that are represented by a linear convolutional neural network (LCN).

Semi-supervised NMF Models for Topic Modeling in Learning Tasks

1 code implementation15 Oct 2020 Jamie Haddock, Lara Kassab, Sixian Li, Alona Kryshchenko, Rachel Grotheer, Elena Sizikova, Chuntian Wang, Thomas Merkh, R. W. M. A. Madushani, Miju Ahn, Deanna Needell, Kathryn Leonard

We propose several new models for semi-supervised nonnegative matrix factorization (SSNMF) and provide motivation for SSNMF models as maximum likelihood estimators given specific distributions of uncertainty.

Stochastic Feedforward Neural Networks: Universal Approximation

no code implementations22 Oct 2019 Thomas Merkh, Guido Montúfar

We investigate different types of shallow and deep architectures, and the minimal number of layers and units per layer that are sufficient and necessary in order for the network to be able to approximate any given stochastic mapping from the set of inputs to the set of outputs arbitrarily well.
