Abstract: An apparatus for performing non-destructive testing is provided. The apparatus includes a housing having a front face for displaying a user interface and a rear face. A plurality of first buttons is disposed on the rear face of the housing adjacent to a side face, and receives a first set of user inputs from a user. One or more second buttons are disposed on the housing and receive a second set of user inputs from the user. The first set of user inputs and the second set of user inputs are received via a forefinger and a thumb, respectively, of the user. The plurality of first buttons and the one or more second buttons are together configured to select a precise value of an operating parameter of the apparatus. Related methods of use are also described.

Abstract: Provided is a model interpretation method, an image processing method, an electronic device and a storage medium, relating to the field of artificial intelligence, in particular to the field of deep learning. The model interpretation method includes: obtaining a token vector corresponding to an image feature input to a first model; obtaining a model prediction result output by the first model; and determining, according to a combination of an attention weight and a gradient, an association relation between the token vector input to the first model and the model prediction result output by the first model, where the association relation is used to characterize interpretability of the first model.
