A multi-modal approach to emotion recognition using undirected topic models

TL;DR: A multi-modal framework for emotion recognition using bag-of-words features and undirected, replicated softmax topic models is proposed here, showing that a turn of 1 second duration can be classified in approximately 666.65ms, thus making this method highly amenable for real-time implementation.
Journal ArticleDOI

Robust Consensus in the Presence of Impulsive Channel Noise

TL;DR: This work is the first of its kind in the literature to propose a consensus algorithm which relaxes the requirement of finite moments on the communication noise and it is shown that the nodes reach consensus asymptotically to a finite random variable.
Proceedings ArticleDOI

On-line laboratory for communication systems using J-DSP

TL;DR: Assessment results indicate that the majority of the students responded that the new JDSP functionality and the associated lab exercises complemented well the theory covered in class and helped them develop intuition on the communications concepts covered in these labs.
Journal ArticleDOI

Within and cross-corpus speech emotion recognition using latent topic model-based features

TL;DR: A supervised replicated softmax model (sRSM), based on restricted Boltzmann machines and distributed representations, is proposed to learn naturally discriminative topics and is evaluated for the recognition of categorical or continuous emotional attributes via within and cross-corpus experiments.
Proceedings ArticleDOI

Supervised local sparse coding of sub-image features for image retrieval

TL;DR: This paper develops a feature extraction method that uses multiple global/local features extracted from large overlapping regions of an image, which they refer to as sub-images, and proposes a procedure for dictionary design and supervised local sparse coding of sub-image heterogeneous features.
