Hi, I am a postdoctoral researcher working with  Prof. Dan Roth in the Department of Computer & Information Science, University of Pennsylvania. I completed my Ph.D. in Computer Science at Ludwig Maximilian University of Munich, under the supervision of  Prof. Hinrich Schütze. 

Research Interests:
  • Deep Learning: big data + annotation
  • Dataless Learning: no big data, no annotation, strong generalization like humans .

Released Resources:
1) FLORS: the state-of-the-art online POS tagger in domain adaptation scenario. It performs online representation learning (i.e., domain adaptation is performed by incrementally adapting word representations to the new domain). (EMNLP'2015)

2) Phrase embeddings: the first version in the world. It contains continuous linguistic phrases like "eye disease'' as well as discontinuous phrases like "turn...on'' etc. (ICLR'2013, ACL'2014)

3) Word Meta-Embeddings: A version of word embeddings which were derived by combining several pre-trained word embedding versions, such as word2vec, GloVe, C&W etc.  (ACL'2016)

4) AttentiveConvNet: An attention-based convolution system. Input: two sentences; output: a highly-expressive representation; task:  reason the sentence relations, e.g., paraphrasing, textual entailment etc. (TACL 2018)
