  • Patent number: 11681872
    Abstract: A language sequence labeling method and includes: reading a first embedding representation of a language sequence, the first embedding representation including a character-level word embedding representation, a pre-trained word embedding representation, and a global word embedding representation of the language sequence, the global word embedding representation referring to a global context representation of the language sequence; performing first depth transformation (DT) encoding on the first embedding representation based on a first DT recurrent neural network (RNN), to output a first hidden-layer state representation corresponding to each word in the language sequence; and decoding the first hidden-layer state representations of the language sequence, to obtain a labeling result of one or more elements in the language sequence.

  • Publication number: 20070003519
    Abstract: The present invention relates to methods for treating cancers by manipulating a target gene expression by up-regulation, silencing and/or down-regulation of the gene, such as EGFR-RP, TRA1, MFGE8, TNFSF13 and ZFP236, respectively. The methods are useful in treating cancers and/or inhibiting tumor growth by enhancing expression of a gene that is validated as a target such as ICT1030, for protein, peptide drug and gene therapy modalities; or by RNA interference to silence and/or down-regulate targets such as ICT1024, ICT1025 and ICT1031 and ICB1003 that are validated for antibody, small molecule and other inhibitor drug modalities.
