Data Augmentation using Random Image Cropping and Patching for Deep CNNs

1 code implementation22 Nov 2018 Ryo Takahashi, Takashi Matsubara, Kuniaki Uehara

We also confirmed that deep CNNs with RICAP achieve better results on classification tasks using CIFAR-100 and ImageNet and an image-caption retrieval task using Microsoft COCO.

Deep Generative Model using Unregularized Score for Anomaly Detection with Heterogeneous Complexity

no code implementations16 Jul 2018 Takashi Matsubara, Kenta Hama, Ryosuke Tachibana, Kuniaki Uehara

Empirical results demonstrate that the unregularized score is robust to the inherent complexity of samples and can be used to better detect anomalies.
