I might be missing something obvious as I am new to machine learning. I am training an SSD Inception V2 for detecting buildings from satellite images. I use the Tensorflow Object Detection API. I am having troubles interpreting why the value of loss seems to change periodically:

loss

Please let me know if I need to add more information

Looks like you may be feeding training data in a very specific way or weights and biases reset after a specific period of time, e.g. end of epoch?

I would start with checking that

  • training and validation sets consist of a desired class ratio
  • datapoints within mini batches are being shuffled
  • model parameters are being correctly updated during training
