Auto-Label Classification Datasets Using CLIP
Blog post from Roboflow
Automating the labeling of large datasets has become more efficient with advancements in deep learning and natural language processing, as demonstrated by using CLIP (Contrastive Language-Image Pretraining) and Roboflow within a Jupyter Notebook environment. CLIP, developed by OpenAI, is a powerful model that learns to associate images and text within a shared embedding space, enabling cross-modal retrieval and understanding. The blog post guides users through the process of setting up the necessary environment, preparing the dataset, extracting image features with CLIP, finding similar images based on text input, and ultimately performing automatic labeling of a classification dataset that includes a variety of artistic styles. This is achieved by calculating the cosine similarity between image features and class text embeddings, with the results saved in a CSV file, significantly reducing the time and effort required for labeling large datasets.
