  • Publication number: 20220093089
    Abstract: A model constructing method for audio recognition is provided. In the method, audio data is obtained. A predicted result of the audio data is determined by using the classification model which is trained by machine learning algorithm. The predicted result includes a label defined by the classification model. A prompt message is provided according to a loss level of the predicted result. The loss level is related to a difference between the predicted result and a corresponding actual result. The prompt message is used to query a correlation between the audio data and the label. The classification model is modified according to a confirmation response of the prompt message, and the confirmation response is related to a confirmation of the correlation between the audio data and the label. Accordingly, the labeling efficiency and predicting correctness can be improved.

  • Patent number: 11099234
    Abstract: A method for loading a probe card into a prober is provided. The method includes placing a probe card on a carrier plate and analyzing signals produced by two detection sensors. The detection sensor produces the correct signal when the probe card is placed in a normal state, and produces a false signal when the probe card is placed in an abnormal state. In addition, the method includes sending the probe card into the prober in response to the correct signals produced by both detection sensors. Alternatively, the method includes removing the probe card from the carrier plate and placing the probe card on the carrier plate again after adjustment of the probe card in response to a false signal produced by either of the detection sensors.
