Does ImageNet have human faces?
An assessment of the 1.4 million images included in the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) dataset found that 17% of the images contain faces, despite the fact that only three of 1,000 categories in the dataset mention people.

What is vgg16 trained on?
VGG-16 is a convolutional neural network that is 16 layers deep. You can load a pretrained version of the network trained on more than a million images from the ImageNet database [1]. The pretrained network can classify images into 1000 object categories, such as keyboard, mouse, pencil, and many animals.
What is the size of ImageNet?
150 GB
Clocking in at 150 GB, ImageNet is quite a beast. It holds 1,281,167 images for training and 50,000 images for validation, organised in 1,000 categories.
Where do the images for ImageNet come from?
Images for ImageNet were collected from various online sources. ImageNet doesn’t own the copyright for any of the images. This has implication on how ImageNet shares the images to researchers. For public access, ImageNet provides image thumbnails and URLs from where the original images were downloaded.
How many synsets are in the ImageNet challenge?
ImageNet Large Scale Visual Recognition Challenge ( ILSVRC) was an annual computer vision contest held between 2010 and 2017. It’s also called ImageNet Challenge. For this challenge, the training data is a subset of ImageNet: 1000 synsets, 1.2 million images.
How are subcategories of geological formations defined in ImageNet?
Treemap visualization of first-level subcategories of geological formations. Source: Gershgorn 2017. In fact, ImageNet did not define these subcategories on its own but derived these from WordNet. WordNet is a database of English words linked together by semantic relationships.
When was the last time the ImageNet challenge was held?
