In caffe's solver.prototxt, I wonder if I set test_iter*test_batchsize=validation_imgs_number, is the Accuracy layer's output the whole validation set accuracy?

Does anyone know this detail?

Thank you very much~

  • Look at the duplicate question. You need to set `test_iter` = `val_num_images` / `test batch_size` to cover the entire validation set each time caffe is in a TEST phase. – Shai Apr 15 '18 at 06:07
  • You know every test process will do test_iter times inference, so is the Accuracy layer' screen output the last time's accuracy? – yuexia_wrp Apr 15 '18 at 08:27
  • it's the average of the Accuracy of all the phase – Shai Apr 15 '18 at 08:37
  • Can you find the code implementation of this point.. – yuexia_wrp Apr 15 '18 at 08:47
  • In accuracy_layer.cu -> Forward_gpu -> top.size() == 1 -> valid_count > 0, there only have: top[0]->mutable_cpu_data()[0] = acc / valid_count; – yuexia_wrp Apr 15 '18 at 09:04
  • but the log display only the average over the entire TEST phase – Shai Apr 15 '18 at 09:06
