Sample Complexity Bounds for Learning High-dimensional Simplices in Noisy Regimes

Amir Hossein Saberi, Amir Najafi, Seyed Abolfazl Motahari +1

In this paper, we find a sample complexity bound for learning a simplex from noisy samples. Assume a dataset of size is given which includes i.i.d. samples drawn from a uniform…

Isoform Function Prediction Using a Deep Neural Network

Sara Ghazanfari, Ali Rasteh, Seyed Abolfazl Motahari +1

Isoforms are mRNAs produced from the same gene site in the phenomenon called Alternative Splicing. Studies have shown that more than 95% of human multi-exon genes have undergone al…

Regularizing Recurrent Neural Networks via Sequence Mixup

Armin Karamzade, Amir Najafi, Seyed Abolfazl Motahari

In this paper, we extend a class of celebrated regularization techniques originally proposed for feed-forward neural networks, namely Input Mixup (Zhang et al., 2017) and Manifold…

Private Shotgun DNA Sequencing

Ali Gholami, Mohammad Ali Maddah-Ali, Seyed Abolfazl Motahari

Current techniques in sequencing a genome allow a service provider (e.g. a sequencing company) to have full access to the genome information, and thus the privacy of individuals re…
