  • Publication number: 20180253660
    Abstract: A method for annotating a batch of original samples is provided. A first subset of original samples, selected from the batch and determined by minimizing an entropy-mean difference between the first subset and the batch, is used for human annotation to yield human-annotated samples. The human-annotated samples are used as training data to configure an annotation process for annotating an input sample to yield an annotated output sample, and a check process for verifying annotation accuracy of the annotated output sample. Remaining original samples in the hatch are processed by the annotation process to yield machine-annotated samples, whose accuracy is verified by the check process. In one embodiment, part of the original samples corresponding to erroneous machine-annotated samples are selected for human annotation. Resultant additional human-annotated samples are used to update the two processes. The remaining original samples not yet annotated are then processed by the two processes.

  • Publication number: 20180165269
    Abstract: A method for organizing and processing feature based data structures that can be used in linguistic spell checking and auto-correction, comprising: splitting an original dictionary into sub-dictionaries based on different values of a common feature such as high frequency words; receiving an input text that contains errors; determining a sub-dictionary selection common feature from the input human-readable text; selecting the sub-dictionary based on the determined sub-dictionary selection feature; executing a first matching in the selected sub-dictionary, wherein a match is found if a similarity between the characters, words, or phrases in proximity of the errors in the input text and a character, word, or phrase in the sub-dictionary is above a threshold; if a unique match is found, the result is returned as an output to correct the errors; otherwise, executing a second matching with a raised threshold, and repeating the second matching until a unique match is found.

  • Patent number: 9459929
    Abstract: A computer implemented method of load shedding used in stream computing system that considers the relative importance of each of the applications processing the incoming input data or events. The method of load shedding method also accounts for system physical constraints, such as memories and CPU utilization. The load shedding method first observes the workload of each application and arriving rate of the incoming input data or events. If the system is under an overloading condition, calculate a input data or event drop ratio for each application such that the projected sum of all applications' workload will be at or below the system capacity when the unprocessed input data or events are dropped according to the drop ratio for each application.

  • Patent number: 9219924
    Abstract: This invention discloses an encoding apparatus and a decoding apparatus for scalable video coding such that a non-scalable video decoder is usable for decoding a scalable video bit-stream comprising a base layer bit-stream and an enhancement layer bit-stream. In one embodiment, a source video frame is downscaled to give a downscaled video frame, which is then encoded into the base layer bit-stream. The difference between the source video frame and an up-scaled video frame reconstructed from the downscaled video frame in the base layer bit-stream yields a residual frame. The residual frame is partitioned into a number of residual sub-frames each having a resolution that is the downscaled video frame's resolution. The residual sub-frames are encoded into the enhancement layer bit-stream. Thereby, a non-scalable encoder is usable to encode both the downscaled video frame and the residual sub-frames, allowing both bit-streams to be decodable by employing only one non-scalable decoder.
