Loss functions for training automatic speech recognition (ASR) models are not set in stone. The older rules of loss functions are not necessarily optimal. Consider connectionist temporal classification (CTC) and see how changing some of its rules enables you to reduce GPU memory, which is required for training and inference of CTC-based models and more. For more information about the…
