Computer vision has evolved from recognizing fixed categories to understanding the relationship between images and text.

CLIP (𝘊𝘰𝘯𝘵𝘳𝘢𝘴𝘵𝘪𝘷𝘦 𝘓𝘢𝘯𝘨𝘶𝘢𝘨𝘦 𝘐𝘮𝘢𝘨𝘦 𝘗𝘳𝘦𝘵𝘳𝘢𝘪𝘯𝘪𝘯𝘨) represents this revolutionary shift.

𝐖𝐡𝐚𝐭 𝐢𝐬 𝐂𝐋𝐈𝐏?

CLIP is an AI model that learns to connect images with their natural language descriptions.

Unlike traditional models limited to predefined categories, CLIP understands images through text, enabling open world recognition without retraining.

The architecture consists of two key components:

𝐈𝐦𝐚𝐠𝐞 𝐄𝐧𝐜𝐨𝐝𝐞𝐫:

Processes visual information using Vision Transformers, converting images into mathematical representations

𝐓𝐞𝐱𝐭 𝐄𝐧𝐜𝐨𝐝𝐞𝐫:

Transforms text descriptions into comparable mathematical formats using Transformer architecture

CLIP learns by looking at millions of image text pairs, figuring out which words belong with which pictures.

– It creates a shared understanding space where:
– Images get converted to numbers
– Text gets converted to the same type of numbers
– Matching pairs are pulled closer together
– Non matching pairs are pushed apart
