Appearance invariance in convolutional networks with neighborhood similarity

no code implementations3 Jul 2017 Tolga Tasdizen, Mehdi Sajjadi, Mehran Javanmardi, Nisha Ramesh

We present a neighborhood similarity layer (NSL) which induces appearance invariance in a network when used in conjunction with convolutional layers.

Mutual Exclusivity Loss for Semi-Supervised Deep Learning

no code implementations9 Jun 2016 Mehdi Sajjadi, Mehran Javanmardi, Tolga Tasdizen

In this paper we consider the problem of semi-supervised learning with deep Convolutional Neural Networks (ConvNets).

Unsupervised Total Variation Loss for Semi-supervised Deep Learning of Semantic Segmentation

2 code implementations4 May 2016 Mehran Javanmardi, Mehdi Sajjadi, Ting Liu, Tolga Tasdizen

This can be seen as a regularization term that promotes piecewise smoothness of the label probability vector image produced by the ConvNet during learning.

Disjunctive Normal Networks

1 code implementation30 Dec 2014 Mehdi Sajjadi, Mojtaba Seyedhosseini, Tolga Tasdizen

Backpropagation, which is used to train artificial neural networks, suffers from the herd effect problem which leads to long training times and limit classification accuracy.
