The network was trained on Ubuntu 16.04 using PyTorch 0.1.12. iNaturalist 2017 contains 859k images from 5000+ natural categories. To address small object size in the dataset, inference was performed on 560×560 resolution images using twelve crops per image at test time. However, we still observe a large difference in accuracy for classes with a similar amount of training data. T.-Y. In addition, many of these datasets were created by searching the internet with automated web crawlers and as a result can contain a large proportion of incorrect images e.g. Example parsing inaturalist dataset View Even manually vetted datasets such as ImageNet [31] have been reported to contain up to four percent error for some fine-grained categories [38]. Existing image classification datasets used in computer vision tend to have an even number of images for each object category. 4 we plot the top one public test set accuracy against the number of training images for each class for [34]. 2017) over datasets that contain textbased data such as cybersecurity-related posts. Training and validation images [186GB] Training and validation annotations [26MB] We collect a challenging dataset of birds where objects appear in clutter, occlusion, and exhibit wider pose variation. We used a learning rate of 0.0045, decayed exponentially by 0.94 every 4 epochs, and RMSProp optimization with a momentum of 0.9 and a decay of 0.9. scientists: The fine print in fine-grained dataset collection.
