    • Event Nugget Detection using Thresholding and Classification Techniques 

      Satyapanich, Taneeya; Finin, Tim (National Institute of Standards and Technology, 2016-11-14)
      This paper describes the Event Nugget Detection system that we submitted to the TAC KBP 2016 Event Track. We sent out two runs; UMBC1 and UMBC2. UMBC1 is a sentence-level classification system based on Convolution Neural ...
    • Hash-Grams: Faster N-Gram Features for Classification and Malware Detection 

      Raff, Edward; Nicholas, Charles (Association for Computing Machinery (ACM), 2018)
      N-grams have long been used as features for classification problems, and their distribution often allows selection of the top-k occurring n-grams as a reliable first-pass to feature selection. However, this top-k selection ...
