Producing an augmented dataset to improve performance of a machine learning model. A test series is created for a first type of data transformation. the test series defining a set of test values for at least one parameter characterizing the first type of data transformation. Test datasets are generated based on a source dataset, each of the test datasets corresponding to a respective test value of the set of test values for said at least one parameter characterizing the first type of data transformation. Each of the test datasets is input to the machine learning model to produce a corresponding model output. At least one score is determined for each test dataset based at least in part on the corresponding model output. Robustness metrics of the first type of data transformation are determined based on a function which maps said at least one score of each of the test datasets to said at least one parameter characterizing the first type of data transformation. A set of one or more data augmentations are determined to be applied to the source dataset based at least in part on said one or more robustness metrics of the first type of data transformation. An augmented dataset is generated based on the source dataset using the determined set of one or more data augmentations.

The invention discloses an electrode powder evaluation method, which comprises the following steps of: reading weight data of a carrier after the electrode powder is added, then driving a crimping end of test equipment to press downwards into an accommodating hole so as to insert a probe into the electrode powder, and then driving an abutting end of the test equipment to abut upwards until the pressure value of a pressure sensor reaches 50, the displacement data is read to calculate the package density, the abutting end is continuously driven to move upwards until the pressure value of the pressure sensor sequentially reaches the value in the increasing test sequence, set voltage is applied to the two voltage probes every time the pressure value of the pressure sensor reaches the value in the increasing test sequence, and the current data of the two current probes are read to calculate the resistivity. After all numerical values in the test sequence are reached, the displacement data are read to calculate the compaction density, so that the resistivity, the compaction density and the package density are tested at the same time in the test process of continuous pressure application, valuable data reference is provided for production control, and the production efficiency is improved.
