摘要： A computer-implemented method for explaining an image classifier, the method comprising: receiving an initial image, the initial image having been wrongly classified by the image classifier; receiving an initial gradient of a function executed by the image classifier generated while classifying the initial image, the function being indicative of a probability for the initial image to belong to an initial class; converting the initial image into a latent vector, the latent vector being a representation of the initial image in a latent space; generating a plurality of perturbation vectors using the initial gradient of the function executed by the image classifier; combining the latent vector with each one of the plurality of perturbation vectors, thereby obtaining a plurality of modified vectors; for each one of the plurality of modified vectors, reconstructing a respective image, thereby obtaining a plurality of reconstructed images; transmitting the reconstructed images to the image classifier; for each one of the plurality of reconstructed images, receiving a respective updated gradient of the function executed by the image classifier; using the respective updated gradients, determining amongst the reconstructed images at least one given reconstructed image for which the respective updated gradient is indicative that a new class different from the initial class has been assigned by the image classifier; and outputting the at least one given reconstructed image.

摘要： FIG. 1 is a perspective view of a bus bar for wind turbine, showing our design;
FIG. 2 is a front view thereof;
FIG. 3 is a rear view thereof;
FIG. 4 is a left view thereof;
FIG. 5 is a right view thereof;
FIG. 6 is a top view thereof; and,
FIG. 7 is a bottom view thereof.
The bus bar for wind turbine is shown with a symbolic break in its length and height as illustrated with the dash-dot broken lines. The appearance of any portion of the bus bar for wind turbine between the break lines forms no part of the claimed design. In the drawings, the evenly spaced broken lines illustrate portions of the bus bar for wind turbine which form no part of the claimed design.-

摘要： There is provided a method and a system for training an extractive machine learning algorithm (MLA) to generate extractive summaries of text documents. Reference documents and associated extractive summaries are received. The extractive MLA is then trained to generate an extractive summary, where the training includes, for a given reference document, encoding, using a sentence encoder, a plurality of reference sentences to obtain an associated plurality of sentence representations, encoding, using a document encoder, the associated plurality of sentence representations to obtain a document representation, extracting, using a decoder and based on the associated plurality of sentence representations and the document representation, a first reference sentence of the plurality of reference sentences to obtain a first extracted sentence. A given parameter is updated based on the first extracted sentence and the given reference document summary. A trained extractive MLA comprising the updated given parameter is output.

摘要： There is described a computer-implemented method for generating a vector representation of an image, the computer-implemented method comprising: receiving a given image and semantic information about the given image; generating a first vector representation of the given image using an image embedding method; generating a second vector representation of the semantic information using a word embedding method; combining the first vector representation of the image to be embedded and the second vector representation of the semantic information together, thereby obtaining a modified vector representation for the image to be embedded; and outputting the modified vector representation.

摘要： A method for generating sound within a predetermined environment, the method comprising: emitting a first audio signal from a first location; and concurrently emitting a second audio signal from a second location, wherein: the first location and second location are distinct within the environment; the first audio signal and second audio signal have the same frequency; and the first audio signal and second audio signal have a phase difference that varies as a function of time to limit the time-averaged interference fluctuation across the environment.

摘要： The valve assembly includes a main valve body defining a first inner cylindrical cavity, a support plate positioned above the main valve body, and an upper valve head positioned above the support plate. The upper valve head includes a bottom planar bottom surface and a plurality of discrete conduits, each conduit extending between an outer end and an inner end. The valve assembly further includes a sealing diaphragm interposed between the support plate and the upper valve head. The diaphragm can be engaged by plungers to selectively open or close corresponding gas circuits.

摘要： A system and method for preparing a shelled crustacean body part for meat extraction are provided. The method involves capturing an image of said body part, evaluating the thickness of the shell from the image, determining from the thickness evaluation at least one laser parameter for forming a line of weakness within the shell, the line of weakness being dimensioned to facilitate meat extraction, while preserving the sensory characteristics of the meat, and sweeping a laser beam on the body part in accordance with the laser parameter to form the line of weakness within the shell. The method and system provide the advantage of facilitating meat extraction without compromising the quality or commercial value of the meat all while increasing productivity and performance in comparison with completely manual extraction techniques.
