Learning to Regress Bodies from Images using Differentiable Semantic Rendering

1 code implementation ICCV 2021 Sai Kumar Dwivedi, Nikos Athanasiou, Muhammed Kocabas, Michael J. Black

For Minimally-Clothed regions, we define the DSR-MC loss, which encourages a tight match between a rendered SMPL body and the minimally-clothed regions of the image.

Cross-topic distributional semantic representations via unsupervised mappings

no code implementations NAACL 2019 Eleftheria Briakou, Nikos Athanasiou, Alexandros Potamianos

In traditional Distributional Semantic Models (DSMs) the multiple senses of a polysemous word are conflated into a single vector space representation.

Neural Activation Semantic Models: Computational lexical semantic models of localized neural activations

1 code implementation COLING 2018 Nikos Athanasiou, Elias Iosif, Alex Potamianos, ros

Neural activation models have been proposed in the literature that use a set of example words for which fMRI measurements are available in order to find a mapping between word semantics and localized neural activations.
