"Loss/regularization_loss' and "Loss/classification_loss" are high is high during the training of a object detection model with "ssd_mobilenet_v2_320x320_coco17_tpu-8"
Hi **@Supriob9** ,

Sorry for the delay, Experiment with different learning rates. Instead of directly setting it to 0.08, try a range of values and monitor the impact on loss.
Increase the variety and intensity of data augmentation techniques. This can help the model generalize better and reduce overfitting, potentially reducing regularization loss.
Experiment with different base feature extractors or backbone architectures. You can try variations of MobileNet, EfficientNet, or other architectures to see if they improve performance.
Adjust the hyperparameters of the feature extractor, such as depth multiplier and minimum depth, to find optimal settings for your dataset.

Thank you!

How can I reduce the loss. Specially the regularization loss and classification_loss are high. I have tried reducing the learning rate to .08 and increasing the batch size to 24. I have added my configurations here.
