    摘要: A learning method for improving image segmentation including steps of: (a) acquiring a (1-1)-th to a (1-K)-th feature maps through an encoding layer if a training image is obtained; (b) acquiring a (3-1)-th to a (3-H)-th feature maps by respectively inputting each output of the H encoding filters to a (3-1)-th to a (3-H)-th filters; (c) performing a process of sequentially acquiring a (2-K)-th to a (2-1)-th feature maps either by (i) allowing the respective H decoding filters to respectively use both the (3-1)-th to the (3-H)-th feature maps and feature maps obtained from respective previous decoding filters of the respective H decoding filters or by (ii) allowing respective K-H decoding filters that are not associated with the (3-1)-th to the (3-H)-th filters to use feature maps gained from respective previous decoding filters of the respective K-H decoding filters; and (d) adjusting parameters of CNN.

    摘要: A method for updating an object detector of an autonomous vehicle to adapt the object detector to a driving circumstance is provided. The method includes steps of: a learning device (a) (i) inputting a training image, corresponding to a driving circumstance, into a circumstance-specific object detector to apply (i-1) convolution to the training image to generate a circumstance-specific feature map, (i-2) ROI pooling to the circumstance-specific feature map to generate a circumstance-specific pooled feature map, and (i-3) fully-connected operation to the circumstance-specific pooled feature map to generate circumstance-specific object detection information and (ii) inputting the circumstance-specific feature map into a circumstance-specific ranking network to (ii-1) apply deconvolution to the circumstance-specific feature map and generate a circumstance-specific segmentation map and (ii-2) generate a circumstance-specific rank score via a circumstance-specific discriminator; and (b) training the circumstance-specific object detector, the circumstance-specific deconvolutional layer, the circumstance-specific convolutional layer, and the circumstance-specific discriminator.

    摘要: A method for training a deep learning network based on artificial intelligence is provided. The method includes steps of: a learning device (a) inputting unlabeled data into an active learning network to acquire sub unlabeled data and inputting the sub unlabeled data into an auto labeling network to generate new labeled data; (b) allowing a continual learning network to sample the new labeled data and existing labeled data to generate a mini-batch, and train the existing learning network using the mini-batch to acquire a trained learning network, wherein part of the mini-batch are selected by referring to specific existing losses; and (c) (i) allowing an explainable analysis network to generate insightful results on validation data and transmit the insightful results to a human engineer to transmit an analysis of the trained learning network and (ii) modifying at least one of the active learning network and the continual learning network.
