    Abstract: A method, apparatus, device and readable medium for transfer learning in machine learning are provided. The method includes: constructing a target model according to the number of classes to be achieved by a target task and a duly-trained source model; obtaining a value of a regularized loss function of the corresponding target model and a value of a cross-entropy loss function of the target model, based on sets of training data in a training dataset of the target task; according to the value of the regularized loss function and the value of the cross-entropy loss function corresponding to each set of training data, updating parameters in the target model by a gradient descent method to implement the training of the target model. The above technical solution avoids excessive constraints on parameters in the prior art, thereby refraining from damaging the training effect of the source model on the target task.

    Abstract: A method and apparatus for processing information are provided. A specific embodiment of the method includes: acquiring image information containing text information, the text information comprising printed characters and non-printed characters; recognizing the text information is the image information to generate display data, the display data comprising a recognition result of the text information; and feeding back the display data to a user. This embodiment helps to reduce the limitations on the acquisition method and the contents of image information, and may enrich the feedback method and the contents of the text information therein.

    Abstract: The present disclosure provides a buffer processing method, apparatus, device and computer storage medium, where the method comprises: if it is detected that a drop of an available bandwidth of a receiving terminal exceeds a preset first threshold, detecting whether a drop of a video frame rate of the receiving terminal exceeds a preset second threshold, the second threshold being smaller than the first threshold; if YES, adjusting a buffer size of the receiving terminal; and if NO, keeping the buffer size of the receiving terminal unchanged. The manner provided by the present disclosure can optimize the buffer of the receiving terminal and reduce the delay.
