Source Identification: A Self-Supervision Task for Dense Prediction

no code implementations5 Jul 2023 Shuai Chen, Subhradeep Kayal, Marleen de Bruijne

The paradigm of self-supervision focuses on representation learning from raw data without the need of labor-consuming annotations, which is the main bottleneck of current data-driven methods.

Tagging Funding Agencies and Grants in Scientific Articles using Sequential Learning Models

no code implementations WS 2017 Subhradeep Kayal, Zubair Afzal, George Tsatsaronis, Sophia Katrenko, Pascal Coupet, Marius Doornenbal, Michelle Gregory

In this paper we present a solution for tagging funding bodies and grants in scientific articles using a combination of trained sequential learning models, namely conditional random fields (CRF), hidden markov models (HMM) and maximum entropy models (MaxEnt), on a benchmark set created in-house.
