Learning Neural Bag-of-Matrix-Summarization with Riemannian Network,
Liu, H., Li, J., Wu, Y., & Ji, R. AAAI 2019. [PDF]


Check for details.

Our codes are based on zzhiwu/SPDNet, and translated into PyTorch.

Different from the original paper, we find that replacing the classifier with the softmax on the distances between the dictionary is more stable.

Note that best of results on AFEW is fine-tuned from the SPDNet.

Feel free to contact to the authors ( if you have any problems.
