Neural Routing in Meta Learning

1 code implementation14 Oct 2022 Jicang Cai, Saeed Vahidian, Weijia Wang, Mohsen Joneidi, Bill Lin

Inspired by the widely recognized finding in neuroscience that distinct parts of the brain are highly specialized for different types of tasks, we aim to improve the model performance of the current meta learning algorithms by selectively using only parts of the model conditioned on the input tasks.

Asymptotic Optimality of Self-Representative Low-Rank Approximation and Its Applications

no code implementations1 Jan 2021 Saeed Vahidian, Mohsen Joneidi, Ashkan Esmaeili, Siavash Khodadadeh, Sharare Zehtabian, Ladislau Boloni, Nazanin Rahnavard, Bill Lin, Mubarak Shah

The approach is based on the concept of {\em self-rank}, defined as the minimum number of samples needed to reconstruct all samples with an accuracy proportional to the rank-$K$ approximation.

Select to Better Learn: Fast and Accurate Deep Learning Using Data Selection From Nonlinear Manifolds

no code implementations CVPR 2020 Mohsen Joneidi, Saeed Vahidian, Ashkan Esmaeili, Weijia Wang, Nazanin Rahnavard, Bill Lin, Mubarak Shah

Finding a small subset of data whose linear combination spans other data points, also called column subset selection problem (CSSP), is an important open problem in computer science with many applications in computer vision and deep learning.

AI-enabled Blockchain: An Outlier-aware Consensus Protocol for Blockchain-based IoT Networks

no code implementations17 Jun 2019 Mehrdad Salimitari, Mohsen Joneidi, Mainak Chatterjee

To that end, we propose AI-enabled blockchain (AIBC) with a 2-step consensus protocol that uses an outlier detection algorithm for consensus in an IoT network implemented on hyperledger fabric platform.

Iterative Projection and Matching: Finding Structure-preserving Representatives and Its Application to Computer Vision

2 code implementations CVPR 2019 Mohsen Joneidi, Alireza Zaeemzadeh, Nazanin Rahnavard, Mubarak Shah

In our algorithm, at each iteration, the maximum information from the structure of the data is captured by one selected sample, and the captured information is neglected in the next iterations by projection on the null-space of previously selected samples.
