Interpreting Differentiable Latent States for Healthcare Time-series Data

no code implementations29 Nov 2023 Yu Chen, Nivedita Bijlani, Samaneh Kouchaki, Payam Barnaghi

Understanding the meaning of latent states is crucial for interpreting machine learning models, assuming they capture underlying patterns.

G-CMP: Graph-enhanced Contextual Matrix Profile for unsupervised anomaly detection in sensor-based remote health monitoring

no code implementations29 Nov 2022 Nivedita Bijlani, Oscar Mendez Maldonado, Samaneh Kouchaki

The Contextual Matrix Profile (CMP) is a configurable 2-dimensional version of the Matrix Profile (MP) that uses the distance matrix of all subsequences of a time series to discover patterns and anomalies.

MiniALBERT: Model Distillation via Parameter-Efficient Recursive Transformers

1 code implementation12 Oct 2022 Mohammadmahdi Nouriborji, Omid Rohanian, Samaneh Kouchaki, David A. Clifton

Different strategies have been proposed in the literature to alleviate these problems, with the aim to create effective compact models that nearly match the performance of their bloated counterparts with negligible performance losses.

On the Effectiveness of Compact Biomedical Transformers

1 code implementation7 Sep 2022 Omid Rohanian, Mohammadmahdi Nouriborji, Samaneh Kouchaki, David A. Clifton

Language models pre-trained on biomedical corpora, such as BioBERT, have recently shown promising results on downstream biomedical tasks.

Privacy-aware Early Detection of COVID-19 through Adversarial Training

no code implementations9 Jan 2022 Omid Rohanian, Samaneh Kouchaki, Andrew Soltan, Jenny Yang, Morteza Rohanian, Yang Yang, David Clifton

One of our main contributions is that we specifically target the development of effective COVID-19 detection models with built-in mechanisms in order to selectively protect sensitive attributes against adversarial attacks.

Folded Hamiltonian Monte Carlo for Bayesian Generative Adversarial Networks

no code implementations29 Sep 2021 Narges Pourshahrokhi, Samaneh Kouchaki, Yunpeng Li, Payam M. Barnaghi

Generative Adversarial Networks (GANs) can learn complex distributions over images, audio, and data that are difficult to model.

A Hamiltonian Monte Carlo Model for Imputation and Augmentation of Healthcare Data

1 code implementation3 Mar 2021 Narges Pourshahrokhi, Samaneh Kouchaki, Kord M. Kober, Christine Miaskowski, Payam Barnaghi

A Bayesian approach to impute missing values and creating augmented samples in high dimensional healthcare data is proposed in this work.

Bridging the Gap: Attending to Discontinuity in Identification of Multiword Expressions

2 code implementations NAACL 2019 Omid Rohanian, Shiva Taslimipoor, Samaneh Kouchaki, Le An Ha, Ruslan Mitkov

We introduce a new method to tag Multiword Expressions (MWEs) using a linguistically interpretable language-independent deep learning architecture.
