Abstract: According to an embodiment, a machine learning model compression system includes a memory and a hardware processor. The hardware processor is coupled to the memory and configured to: analyze an eigenvalue of each layer of a machine learning model by using a data set and the machine learning model, the machine learning model having been learned based on the data set; determine a search range of a compressed model based on a count of eigenvalues, each of which is used for calculating a first value and causes the first value to exceed a predetermined threshold; select a parameter for determining a structure of the compressed model included in the search range; generate the compressed model by using the parameter, and judge whether the compressed model satisfies one or more predetermined restriction conditions or not.

Abstract: According to an embodiment, a learning method of optimizing a neural network, includes updating and specifying. In the updating, each of a plurality of weight coefficients included in the neural network is updated so that an objective function obtained by adding a basic loss function and an L2 regularization term multiplied by a regularization strength is minimized. In the specifying, an inactive node and an inactive channel are specified among a plurality of nodes and a plurality of channels included in the neural network.

Abstract: An image processing apparatus includes processing circuitry configured: to obtain a plurality of images taken so as to include a target site of a subject in temporal phases; and to calculate an index indicating a state of an adhesion at a boundary between a first site of the subject corresponding to a first region and a second site of the subject corresponding to a second region, by using classification information used for classifying each of pixels into one selected from between a first class related to the first region and a second class related to a second region positioned adjacent to the first region in a predetermined direction, on a basis of mobility information among the images in the temporal phases with respect to the pixels in the images that are arranged in the predetermined direction across the boundary between the first region and the second region of the images.

Abstract: According to one embodiment, an image processing apparatus includes processing circuitry. The processing circuitry is configured to acquire medical image data. The processing circuitry is configured to obtain spatial distribution of likelihood values representing a likelihood of corresponding to a textual pattern in a predetermined region of a medical image for each of a plurality of textual patterns based on the medical image data.
