[{"type":"conference","publication":"ICASSP 2019, Brighton, UK","abstract":[{"text":"We propose a training scheme to train neural network-based source separation algorithms from scratch when parallel clean data is unavailable. In particular, we demonstrate that an unsupervised spatial clustering algorithm is sufficient to guide the training of a deep clustering system. We argue that previous work on deep clustering requires strong supervision and elaborate on why this is a limitation. We demonstrate that (a) the single-channel deep clustering system trained according to the proposed scheme alone is able to achieve a similar performance as the multi-channel teacher in terms of word error rates and (b) initializing the spatial clustering approach with the deep clustering result yields a relative word error rate reduction of 26% over the unsupervised teacher.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":368225,"access_level":"open_access","file_name":"ICASSP_2019_Drude_Paper.pdf","file_id":"12925","date_updated":"2019-08-14T07:19:13Z","creator":"huesera","date_created":"2019-08-14T07:19:13Z"}],"status":"public","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"12874","user_id":"59789","department":[{"_id":"54"}],"ddc":["000"],"language":[{"iso":"eng"}],"file_date_updated":"2019-08-14T07:19:13Z","has_accepted_license":"1","year":"2019","citation":{"short":"L.
