Abstract: The technology disclosed presents a novel spatial attention model that uses current hidden state information of a decoder long short-term memory (LSTM) to guide attention and to extract spatial image features for use in image captioning. The technology disclosed also presents a novel adaptive attention model for image captioning that mixes visual information from a convolutional neural network (CNN) and linguistic information from an LSTM. At each timestep, the adaptive attention model automatically decides how heavily to rely on the image, as opposed to the linguistic model, to emit the next caption word. The technology disclosed further adds a new auxiliary sentinel gate to an LSTM architecture and produces a sentinel LSTM (Sn-LSTM). The sentinel gate produces a visual sentinel at each timestep, which is an additional representation, derived from the LSTM's memory, of long and short term visual and linguistic information.

Abstract: Concurrent threads may be synchronized at the level of the memory words they access rather than at the level of the lock that protects the execution of critical sections. Each lock may be associated with an array of flags and each flag may indicate ownership of certain memory words. A pessimistic thread may set flags corresponding to memory words it is accessing in the critical section, while an optimistic thread may read the corresponding flag before any memory access to ensure that the flag is not set and that therefore the associated memory word is not being accessed by the other thread. Thus, optimistic threads that do not have conflicts with the pessimistic thread may not have to wait for the pessimistic thread to release the lock before proceeding.
