# Object Class Recognition Requirements

OpenText recommends training object class recognition using a GPU.

Memory use during training is determined by your chosen recognizer type and batch size. Ensure that your GPU has sufficient memory by consulting the following table. Reducing the batch size has no affect on recognition accuracy or run-time performance, but training will take longer because fewer images are processed concurrently. You can change the values of these training options by using the action SetObjectClassRecognizerTrainingOption.

Value of batch_size training option | 1 | 2 | 4 (default) | 8 | 16
--- | --- | --- | --- | --- | ---
GPU memory use (GB) with `recognizer_type=small` | 1 | 1.6 | 3.1 | 5.4 | 9.7
GPU memory use (GB) with `recognizer_type=large` | 2.9 | 4.5 | 7.7 | 14.4 |
