• Abstract: Signers compose sign language phonemes that enable communication by combining phonological parameters such as handshape, orientation, location, movement, and non-manual features. Linguistic research often breaks down signs into their constituent parts to study sign languages and often a lot of effort is invested into the annotation of the videos. In this work we show how a single model can be used to recognise the individual phonological parameters within sign languages with the aim of either to assist linguistic annotations or to describe the signs for the sign recognition models. We use Danish Sign Language data set `Ordbog over Dansk Tegnsprog' to generate multiple data sets using pose estimation model, which are then used for training the multi-label Fast R-CNN model to support multi-label modelling. Moreover, we show that there is a significant co-dependence between the orientation and location phonological parameters in the generated data and we incorporate this co-dependence in the model to achieve better performance.

  We propose a unified framework for continuous sign language production, easing communication between sign and non-sign language users. A sequence diffusion model, utilizing embeddings extracted from text or speech, is crafted to generate sign predictions step by step. Experiments on How2Sign and PHOENIX14T datasets demonstrate that our model achieves competitive performance in sign language production.

  Our model iteratively selects or synthesizes a data-point according to one of a range of information-theoretic policies. We find that the information-theoretic policies that our model uses to select items to query the informant achieve sample efficiency comparable to, or greater than, fully supervised approaches.

  Click-through rate (CTR) prediction plays as a core function module in personalized online services. Traditional ID-based models for CTR prediction take as inputs the one-hot encoded ID features of tabular modality. Pretrained Language Models(PLMs) has given rise to another paradigm, which takes as inputs the sentences of textual modality. We propose to conduct Fine-grained feature-level ALignment between ID-based Models and Pretrained Language Models(FLIP) for CTR prediction.

  We study the feasibility of utilizing multilingual sign language corpora to facilitate continuous sign language recognition. We first build two sign language dictionaries containing isolated signs that appear in two datasets. Then we identify the sign-to-sign mappings between two sign languages via a well-optimized isolated sign language recognition model.

  Sign languages are visual languages, with vocabularies as rich as their spoken language counterparts. Current deep-learning based Sign Language Production (SLP) models produce under-articulated skeleton pose sequences. We tackle large-scale SLP by learning to co-articulate between dictionary signs. We also propose SignGAN, a pose-conditioned human synthesis model that produces photo-realistic sign language videos.

  End-to-end sign language generation models do not accurately represent the prosody in sign language. We aim to improve the prosody in generated sign languages by modeling intensification in a data-driven manner. We find that our efforts in intensification modeling yield better results when evaluated with automatic metrics.

With a limited dataset, orders of magnitude smaller than that required by contemporary generative models, our model closely approximates babbling speech. We show the effect of training with auxiliary text LMs, multitask learning objectives, and auxiliary articulatory features.
