Abstract: In a corpus of scientific articles such as a digital library, documents are connected by citations and one document plays two different roles in the corpus: document itself and a citation of other documents. A Bernoulli Process Topic (BPT) model is provided which models the corpus at two levels: document level and citation level. In the BPT model, each document has two different representations in the latent topic space associated with its roles. Moreover, the multi-level hierarchical structure of the citation network is captured by a generative process involving a Bernoulli process. The distribution parameters of the BPT model are estimated by a variational approximation approach.

Abstract: Certain features relate to optimizing the processing of downlink data in a telecommunications system by capturing a downlink data stream and transferring the downlink data to a memory device in parallel. A processing device can capture a first set of downlink data blocks from a base station and store the first set of downlink data blocks to a memory device. Once a sufficient number of downlink data blocks are written to the memory device, the first set of data blocks can be transferred to a digital signal processor. A second set of data blocks can be captured substantially simultaneous to the first set of data blocks being transferred to the digital signal processor. In additional aspects, the second set of data blocks can be processed by the digital signal processor substantially simultaneous to additional data blocks being captured and stored in the memory device.
