Unsupervised Pre-training for Person Re-identification

LUPerson The repository is for our CVPR2021 paper Unsupervised Pre-training for Person Re-identification. LUPerson Dataset LUPerson is currently the largest unlabeled dataset for Person Re-identification, which is used for Unsupervised Pre-training. LUPerson consists of 4M images of over 200K identities and covers a much diverse range of capturing environments. Details can be found at ./LUP.

Training BERT Text Classifier on Tensor Processing Unit (TPU)

Training hugging face most famous model on TPU for social media Tunisian Arabizi sentiment analysis.   Introduction The Arabic speakers usually express themself in local dialect on social media, so Tunisians use Tunisian Arabizi which consists of Arabic written in form of Latin alphabets. The sentiment analysis relies on cultural knowledge and word sense with contextual information. We will be using both Arabizi dialect and sentimental analysis to solve the problem in this project. The competition is hosted on Zindi which […]

Dialogue in the Wild: Learning from a Deployed Role-Playing Game with Humans and Bots

Abstract Much of NLP research has focused on crowdsourced static datasets and the supervised learning paradigm of training once and then evaluating test performance. As argued in de Vries et al. (2020), crowdsourced data has the issues of lack of naturalness and relevance to real-world use cases, while the static dataset paradigm does not allow for a model to learn from its experiences of using language (Silver et al., 2013). In contrast, one might hope for machine learning systems that […]

Evaluating the Factual Consistency of Abstractive Text Summarization

factCC Evaluating the Factual Consistency of Abstractive Text SummarizationAuthors: Wojciech Kryściński, Bryan McCann, Caiming Xiong, and Richard Socher Introduction Currently used metrics for assessing summarization algorithms do not account for whether summaries are factually consistent with source documents.We propose a weakly-supervised, model-based approach for verifying factual consistency and identifying conflicts between source documents and a generated summary.Training data is generated by applying a series of rule-based transformations to the sentences of source documents.The factual consistency model is then trained jointly […]
