Tagger: Deep Unsupervised Perceptual Grouping

2 code implementations NeurIPS 2016 Klaus Greff, Antti Rasmus, Mathias Berglund, Tele Hotloo Hao, Jürgen Schmidhuber, Harri Valpola

We present a framework for efficient perceptual inference that explicitly reasons about the segmentation of its inputs and features.

Bidirectional Recurrent Neural Networks as Generative Models

no code implementations NeurIPS 2015 Mathias Berglund, Tapani Raiko, Mikko Honkala, Leo Kärkkäinen, Akos Vetek, Juha T. Karhunen

Although unidirectional RNNs have recently been trained successfully to model such time series, inference in the negative time direction is non-trivial.

Scalable Gradient-Based Tuning of Continuous Regularization Hyperparameters

1 code implementation20 Nov 2015 Jelena Luketina, Mathias Berglund, Klaus Greff, Tapani Raiko

Hyperparameter selection generally relies on running multiple full training trials, with selection based on validation set performance.

Techniques for Learning Binary Stochastic Feedforward Neural Networks

no code implementations11 Jun 2014 Tapani Raiko, Mathias Berglund, Guillaume Alain, Laurent Dinh

Our experiments confirm that training stochastic networks is difficult and show that the proposed two estimators perform favorably among all the five known estimators.

Stochastic Gradient Estimate Variance in Contrastive Divergence and Persistent Contrastive Divergence

no code implementations20 Dec 2013 Mathias Berglund, Tapani Raiko

Contrastive Divergence (CD) and Persistent Contrastive Divergence (PCD) are popular methods for training the weights of Restricted Boltzmann Machines.
