Human Activity Recognition Using Robust Adaptive Privileged Probabilistic Learning

no code implementations19 Sep 2017 Michalis Vrigkas, Evangelos Kazakos, Christophoros Nikou, Ioannis A. Kakadiaris

In this work, a novel method based on the learning using privileged information (LUPI) paradigm for recognizing complex human activities is proposed that handles missing information during testing.

Curriculum Learning of Visual Attribute Clusters for Multi-Task Classification

no code implementations19 Sep 2017 Nikolaos Sarafianos, Theodore Giannakopoulos, Christophoros Nikou, Ioannis A. Kakadiaris

In this paper, we introduce a novel method to combine the advantages of both multi-task and curriculum learning in a visual attribute classification framework.

Inferring Human Activities Using Robust Privileged Probabilistic Learning

no code implementations31 Aug 2017 Michalis Vrigkas, Evangelos Kazakos, Christophoros Nikou, Ioannis A. Kakadiaris

Classification models may often suffer from "structure imbalance" between training and testing data that may occur due to the deficient data collection process.

Curriculum Learning for Multi-Task Classification of Visual Attributes

no code implementations29 Aug 2017 Nikolaos Sarafianos, Theodore Giannakopoulos, Christophoros Nikou, Ioannis A. Kakadiaris

Visual attributes, from simple objects (e. g., backpacks, hats) to soft-biometrics (e. g., gender, height, clothing) have proven to be a powerful representational approach for many applications such as image description and human identification.

Predicting Privileged Information for Height Estimation

no code implementations9 Feb 2017 Nikolaos Sarafianos, Christophoros Nikou, Ioannis A. Kakadiaris

In this paper, we propose a novel regression-based method for employing privileged information to estimate the height using human metrology.
