This model (Coin-CLIP) is built upon OpenAI's CLIP (ViT-B/32) model and fine-tuned on a dataset of more than 340,000 coin images using contrastive learning techniques. This specialized model is designed to significantly improve feature extraction for coin images, leading to more accurate image-based search capabilities. Coin-CLIP combines the power of Visual Transformer (ViT) with CLIP's multimodal learning capabilities, specifically tailored for the numismatic domain.

Key Features:

State-of-the-art coin image retrieval;
Enhanced feature extraction for numismatic images;
Seamless integration with CLIP's multimodal learning.

本模型（Coin-CLIP）在 OpenAI 的 CLIP (ViT-B/32) 模型基础上，利用对比学习技术在超过 340,000 张硬币图片数据上微调得到的。 Coin-CLIP 旨在提高模型针对硬币图片的特征提取能力，从而实现更准确的以图搜图功能。该模型结合了视觉变换器（ViT）的强大功能和 CLIP 的多模态学习能力，并专门针对硬币图片进行了优化。
