The application discloses a semi-supervised HRRP noise label filtering method based on early learning guidance, comprising the following steps: constructing an HRRP training data set and a deep neural network model; pre-training the deep neural network model; predicting the HRRP training data set by using the pre-trained network model and dividing the HRRP training data set into two data sets according to the confidence; constructing a known label data set and an unknown label data set to form a semi-supervised training data set and performing data enhancement; semi-supervised training the network model by using the enhanced data; generating the label of the unknown label data set by using the semi-supervised trained network model and fully supervised training the network model; and target recognition of the HRRP data by using the fully supervised trained network model. The application uses a generalized cross-entropy loss function in the early learning training stage of the model, proposes a data enhancement scheme suitable for HRRP, can better reduce the influence of noise labels on the model, and has better stability and implementability.

The utility model belongs to the field of aviation heat treatment technology, concretely relates to a kind of part heat treatment anti-deformation tooling.A detachable multipurpose quenching rack, including partition disc, placing punched plate on partition disc, the diameter of through hole A on punched plate is less than the diameter of through hole B on partition disc, and through hole A, through hole B are communicated, for the vertical insertion of part;The number of through hole A, through hole B is multiple.The utility model has the following advantages: the part can be placed vertically, solves the problem that the existing part is easy to deform during heat treatment, and the deformation is minimized as much as possible;Increase the loading capacity of the part, simple operation, different part number parts are not easy to confuse, the appropriate tooling can be selected according to the size and type of the part, so that the heat treatment production efficiency and part quality are greatly improved;Tooling structure is simple, long service life, strong carrying capacity.
