paper summary: “VarifocalNet: An IoU-aware Dense Object Detector”(VFNet)

arxiv: https://arxiv.org/abs/2008.13367 key points another anchor-free point based object detection network introduce new loss, varifocal loss which is a forked version from focal loss. Makes some changes from focal loss to compensate positive/negative imbalance futher. instead of prediction classification and IOU score separately, this work predicts a single scalar which Read more…

few shot learning good articles

https://towardsdatascience.com/advances-in-few-shot-learning-a-guided-tour-36bc10a68b77 great brief summary over matching networks, prototypical networks, model-agnostic meta-learning(MAML). well, the first two topics are well explained but MAML section needs a lot more thinking to understand. Also, I think MAML is closer to the topic of meta-learning rather than few shot learning. https://arxiv.org/pdf/2008.06365.pdf “An Overview of Deep Read more…
