What I read lately

  • Link: https://arxiv.org/pdf/1611.01144v1.pdf
  • Continuous distribution on the simplex which approximates discrete vectors (one hot vectors) and differentiable by its parameters with reparametrization trick used in VAE.
  • It is used for semi-supervised learning.


  • Learning useful unsupervised image representations by using triplet loss on image patches. The triplet is defined by two image patches from the same images as the anchor and the positive instances and a patch from a different image which is the negative.  It gives a good boost on CIFAR-10 after using it as a pretraning method.
  • How would you apply to real and large scale classification problem?




  • For 110-layers ResNet the most contribution to gradient updates come from the paths with 10-34 layers.
  • ResNet trained with only these effective paths has comparable performance with the full ResNet. It is done by sampling paths with lengths in the effective range for each mini-batch.
  • Instead of going deeper adding more residual connections provides more boost due to the notion of exponential ensemble of shallow networks by the residual connections.
  • Removing a residual block from a ResNet has negligible drop on performance in test time in contrast to VGG and GoogleNet.

Share Research Data Sets via Torrent

I recognized a newbie but very bright idea today. The idea is to share academic data sets and papers via torrent. Especially, if you are working on big scale of data sets like ImageNet , having such a distributed approach is just delighting (albeit it presently does not include ImageNet) because in many cases of downloads, in the course of time your download speed starts to attenuate a very small values, even with additional download peers it gets worse. However, in such a torrent based system, it is on the other way around. If you are familiar to bit-torrent, you well know that as the data is distributed to many machines, you experienced faster download speed owing to the nature of torrent system.

A good document organizing tool Zotero

I just started to be a graduate student who need to be ready for reading lots of and lots of article and papers online. Thus I search a tool that can help me while dealing with all these stuffs and I found that tool ZOTERO. I started to use it for taking notes about papers and keep track of the articles and sources online. It is really great tool and I thing someone like me can find it useful. You might watch that informative video.
