  • Publication number: 20180032897
    Abstract: Embedding representation for a document is generated based on clustering words in the document. Representative clusters are selected and weighted sum of the embeddings of the words in the selected clusters is determined as a document embedding. Documents are labeled based on document embeddings. A machine learning algorithm is trained using the documents. The machine learning algorithm predicts a label of a given document based on the given document's document embedding.

  • Publication number: 20170374650
    Abstract: Embodiments of the present application provide a method for information transmission. The method includes determining multiple enhanced transmission occasion configurations; determining a first enhanced transmission occasion configuration according to a channel loss magnitude with a user equipment, a time width occupied by the enhanced transmission occasion is greater than a time width occupied by a non-enhanced transmission occasion; sending information according to the first enhanced transmission occasion configuration. Embodiments of the present application also provide a base station and user equipment, configured to determine an enhanced transmission occasion configuration according to the range which the channel loss magnitude belongs to. Therefore, the base station and user equipment may send and/or receive information on a suitable time-frequency resource and power configuration according to the channel loss magnitude, thus, the resource allocation is optimized, and the power consumption is saved.
