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

no code implementations9 Sep 2022 Amir Hossein Saberi, Amir Najafi, Seyed Abolfazl Motahari, Babak H. Khalaj

Also, we theoretically show that in order to achieve this bound, it is sufficient to have $n\ge\left(K^2/\varepsilon^2\right)e^{\Omega\left(K/\mathrm{SNR}^2\right)}$ samples, where $\mathrm{SNR}$ stands for the signal-to-noise ratio.

Regularizing Recurrent Neural Networks via Sequence Mixup

no code implementations27 Nov 2020 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 Mixup (Verma et al., 2018), to the realm of Recurrent Neural Networks (RNN).

On Statistical Learning of Simplices: Unmixing Problem Revisited

no code implementations18 Oct 2018 Amir Najafi, Saeed Ilchi, Amir H. Saberi, Seyed Abolfazl Motahari, Babak H. Khalaj, Hamid R. Rabiee

We study the sample complexity of learning a high-dimensional simplex from a set of points uniformly sampled from its interior.

Cell Identity Codes: Understanding Cell Identity from Gene Expression Profiles using Deep Neural Networks

no code implementations13 Jun 2018 Farzad Abdolhosseini, Behrooz Azarkhalili, Abbas Maazallahi, Aryan Kamal, Seyed Abolfazl Motahari, Ali Sharifi-Zarchi, Hamidreza Chitsaz

Although we use an unsupervised approach to train the autoencoder, we show different values of the CIC are connected to different biological aspects of the cell, such as different pathways or biological processes.

Learning of Gaussian Processes in Distributed and Communication Limited Systems

no code implementations7 May 2017 Mostafa Tavassolipour, Seyed Abolfazl Motahari, Mohammad-Taghi Manzuri Shalmani

In particular, it is shown that the performance of one of the practical schemes which is called per-symbol quantization is very close to the optimal one.
