Abstract: A method and processor for classifying documents are provided. Using a classification model with classifiers, items are classified into classes. The method includes acquiring a model for classification, creating a training dataset with items and class labels, and training a new classifier for an additional class not in the original set. This results in a modified model that includes both the original classifiers and the new classifier, allowing for classification into an expanded set of classes. The method involves generating a training dataset, training a new classifier, modifying the classification model, and determining a predicted class for items, including the new class.

Abstract: A method and an electronic device for generating an anonymized audio output are provided. The method, executable by the electronic device, comprises acquiring an audio recording of a speaker; stochastically determining a base pitch value based on at least a first probabilistic function; segmenting the original audio input into a plurality of audio segments, each of the plurality of audio segments being associated with a respective pitch. For each audio segment, the method further comprises generating a pitch adjustment value using a combination of the base pitch value of the segment and a value determined using a second probabilistic function; generating an adjusted audio segment by adjusting the pitch of the audio segment using the pitch adjustment value, the adjusted audio segment having an adjusted pitch that is different from the original pitch; generating the anonymized audio output by combining the adjusted audio segments.

Abstract: A method for sludge dewatering using kitchen waste to synergistically enhance a coupling of an anaerobic biological acidification and a low-temperature hydrothermal of excess sludge is disclosed. The method includes the following steps: first, uniformly mixing the excess sludge from a sewage treatment plant and the kitchen waste for an anaerobic biological acidification reaction at 36.5-37.5° C. for 2-4 days; then, concentrating the acidified mixture by centrifugation at a speed of 3000-5000 rpm for 5-10 min; performing a low-temperature thermal hydrolysis treatment on a residue obtained after removing a supernatant for 15-30 min at 100-140° C.; and after the thermal hydrolysis treatment is finished, cooling and dewatering to obtain a dewatered sludge cake and a dewatered filtrate. The new method realizes high-efficiency sludge dewatering and innocuous utilization of dewatered filtrate and sludge cake without adding chemical reagents and effectively avoids generating hardly-degradable chemical oxygen demand.

Abstract: A hardware pixel processing pipeline and a video processing instruction set accelerate image processing and/or video decompression. The pixel processing pipeline uses hardware components to more efficiently perform color space conversion and horizontal upscaling. Additionally, the pixel processing pipeline also reduces the size of its output data to conserve bandwidth. A specialized video processing instruction set allows further acceleration of video processing or video decoding by allowing receipt of a single instruction to cause multiple addition operation or interpolation of multiple pairs of pixels in parallel.
