![]() ![]() ![]() A token is added to serve as representation of an entire image. To feed images to the Transformer encoder, each image is split into a sequence of fixed-size non-overlapping patches, ![]() Product between the projected image and text features is then used as a similar score. Both the text and visual features are then projected to a latent space with identical dimension. CLIP uses a ViT like transformer to get visual features and a causal language model to get the textįeatures. It can be used for image-text similarity and for zero-shot imageĬlassification. We release our code and pre-trainedĬLIP is a multi-modal vision and language model. Without needing to use any of the 1.28 million training examples it was trained on. For instance, we match the accuracy of the original ResNet-50 on ImageNet zero-shot Model transfers non-trivially to most tasks and is often competitive with a fully supervised baseline without the needįor any dataset specific training. Such as OCR, action recognition in videos, geo-localization, and many types of fine-grained object classification. The performance of this approach by benchmarking on over 30 different existing computer vision datasets, spanning tasks Learned visual concepts (or describe new ones) enabling zero-shot transfer of the model to downstream tasks. After pre-training, natural language is used to reference Million (image, text) pairs collected from the internet. With which image is an efficient and scalable way to learn SOTA image representations from scratch on a dataset of 400 We demonstrate that the simple pre-training task of predicting which caption goes Learning directly from raw text about images is a promising alternative which leverages a Restricted form of supervision limits their generality and usability since additional labeled data is needed to specifyĪny other visual concept. State-of-the-art computer vision systems are trained to predict a fixed set of predetermined object categories. The abstract from the paper is the following: Instructed in natural language to predict the most relevant text snippet, given an image, without directly optimizingįor the task, similarly to the zero-shot capabilities of GPT-2 and 3. (Contrastive Language-Image Pre-Training) is a neural network trained on a variety of (image, text) pairs.
