摘要： A system for generating a forecast including a classifier module for receiving from a user, at least one feature and classifying the at least one feature into a plurality of priority groups based on a user preference. The system further includes an artificial intelligence (AI) forecast module in communication with the classifier module for processing the plurality of priority groups with at least one feature.

摘要： A vehicle approach notifying device for notifying the approach of a vehicle by causing a loudspeaker to output a warning sound includes: a storage that stores a predetermined threshold of sound pressure; and a controller that: (i) causes a loudspeaker disposed outside a cabin of the vehicle to output the warning sound at a first sound pressure determined in accordance with a speed of the vehicle when a sound pressure of the warning sound acquired by a microphone disposed outside the vehicle is less than or equal to the predetermined threshold; and (ii) causes the loudspeaker to output the warning sound at a sound pressure lower than the first sound pressure when the sound pressure of the warning sound acquired by the microphone exceeds the predetermined threshold.

摘要： An active noise reduction device includes: a reference signal inputter; an adaptive filter; a μ adjuster that calculates a step size parameter by multiplying a reference value for the step size parameter by a correction coefficient that is proportional to a reciprocal of a first representative input value that indicates a signal level of the reference signal in a first predetermined period; a filter coefficient updater that updates adaptive filter coefficient W by using the step size parameter calculated; and a determiner. When it is determined that a second representative input value is greater than a threshold value, at least one of the adaptive filter or the filter coefficient updater is transitioned from a normal state to a restriction state in which an effect of reducing noise is smaller than in the normal state.

摘要： A method for developing machine-learning (ML) based tool including initializing an input dataset, which is pre-processed by a first model to harmonize the dataset. Historical data similar to the input data set is fetched from a historical database. Based thereupon a controller recommends a method and a control-setting associated with the identified model for the visual inspection process to a user. Thereafter, the dataset is annotated by a second model to define a labelled data set. A plurality of features are extracted with respect to the data set through a feature extractor. A machine-learning classifier operates upon the extracted features and classifies the dataset with respect to one or more labels. A meta controller communicates with one or more of the first model, the second model, the feature extractor and the selected classifier for assessing a performance of at least one of first model and the feature extractor.
