Memorization Capacity of Neural Networks with Conditional Computation

no code implementations20 Mar 2023 Erdem Koyuncu

For Rectified Linear Unit (ReLU) networks without conditional computation, it is known that memorizing a collection of $n$ input-output relationships can be accomplished via a neural network with $O(\sqrt{n})$ neurons.

Class Based Thresholding in Early Exit Semantic Segmentation Networks

no code implementations27 Oct 2022 Alperen Görmez, Erdem Koyuncu

We propose Class Based Thresholding (CBT) to reduce the computational cost of early exit semantic segmentation models while preserving the mean intersection over union (mIoU) performance.

Pruning Early Exit Networks

no code implementations8 Jul 2022 Alperen Görmez, Erdem Koyuncu

Deep learning models that perform well often have high computational costs.

Federated Momentum Contrastive Clustering

no code implementations10 Jun 2022 Runxuan Miao, Erdem Koyuncu

We present federated momentum contrastive clustering (FedMCC), a learning framework that can not only extract discriminative representations over distributed local data but also perform data clustering.

Multiplication-Avoiding Variant of Power Iteration with Applications

no code implementations22 Oct 2021 Hongyi Pan, Diaa Badawi, Runxuan Miao, Erdem Koyuncu, Ahmet Enis Cetin

In this paper, we introduce multiplication-avoiding power iteration (MAPI), which replaces the standard $\ell_2$-inner products that appear at the regular power iteration (RPI) with multiplication-free vector products which are Mercer-type kernel operations related with the $\ell_1$ norm.

Robust Principal Component Analysis Using a Novel Kernel Related with the L1-Norm

no code implementations25 May 2021 Hongyi Pan, Diaa Badawi, Erdem Koyuncu, A. Enis Cetin

We consider a family of vector dot products that can be implemented using sign changes and addition operations only.

E$^2$CM: Early Exit via Class Means for Efficient Supervised and Unsupervised Learning

1 code implementation1 Mar 2021 Alperen Görmez, Venkat R. Dasari, Erdem Koyuncu

Moreover, if there are no limitations on the training time budget, E$^2$CM can be combined with an existing early exit scheme to boost the latter's performance, achieving a better trade-off between computational cost and network accuracy.

Quantizing Multiple Sources to a Common Cluster Center: An Asymptotic Analysis

no code implementations23 Oct 2020 Erdem Koyuncu

We consider quantizing an $Ld$-dimensional sample, which is obtained by concatenating $L$ vectors from datasets of $d$-dimensional vectors, to a $d$-dimensional cluster center.

Robust and Computationally-Efficient Anomaly Detection using Powers-of-Two Networks

no code implementations30 Oct 2019 Usama Muneeb, Erdem Koyuncu, Yasaman Keshtkarjahromi, Hulya Seferoglu, Mehmet Fatih Erden, Ahmet Enis Cetin

We propose a technique to increase robustness and reduce computational complexity in a Convolutional Neural Network (CNN) based anomaly detector that utilizes the optical flow information of video data.

A Generalization of Principal Component Analysis

no code implementations29 Oct 2019 Samuele Battaglino, Erdem Koyuncu

Conventional principal component analysis (PCA) finds a principal vector that maximizes the sum of second powers of principal components.
