    摘要: There is provided a system and method for determining individualized head related transfer functions (HRTF) for a user. The method including: receiving measurement data from the user, the measurement data generated by repeatedly emitting an audible reference sound at positions in space around the user and, during each emission, recording sounds received near each ear of the user, the measurement data including, for each emission, the recorded sounds and positional information of the emission; determining the individualized HRTF by updating a decoder of a trained generative artificial neural network model, the decoder receives the measurement data as input, the trained generative artificial neural network model including an encoder and the decoder, the generative artificial neural network model is trained using data gathered from a plurality of test subjects with known spectral representations and directions for associated HRTFs at different positions in space; and outputting the individualized HRTF.

    摘要: A system, method and computer program product for evaluating a multi-label classification machine learning model. A model labelled dataset is received from the model and includes a plurality of data elements each labelled with zero or more model predicted labels of q potential classes. A multi-label confusion matrix is defined to include q+1 rows with q rows for true labels and 1 row for no true label and q+1 columns with q columns for predicted labels and 1 column for no predicted label. The matrix is populated by comparing the model labelled dataset with a true labelled dataset. At least one performance metric is calculated from the populated multi-label confusion matrix.
