AltCLIP-m18

AltCLIP-m18

简介 Brief Introduction

继双语模型AltCLIP与9语模型AltCLIP-m9之后，我们训练了18语CLIP模型。命名为AltCLIP-m18。它支持英语、中文、日语、泰语、韩语、印地语、乌克兰语、阿拉伯语、土耳其语、越南语、波兰语、荷兰语、葡萄牙语、意大利语、西班牙语、德语、法语和俄语。

AltCLIP-m18模型可以为AltDiffusion-m18模型提供支持，关于AltDiffusion模型的具体信息可查看此教程 。

模型代码已经在 FlagAI 上开源，权重位于我们搭建的 modelhub 上。我们还提供了微调，推理，验证的脚本，欢迎试用。

Following the bilingual model AltCLIP and the nine-language model AltCLIP-m9, we trained the eighteen-language CLIP model, Named AltCLIP-m18. It supports English, Chinese, Japanese, Thai, Korean, Hindi, Ukrainian, Arabic, Turkish, Vietnamese, Polish, Dutch, Portuguese, Italian, Spanish, German, French, and Russian.

The AltCLIP-m18 model can provide support for the AltDiffusion-m18 model. Specific information on the AltDiffusion modle can be found in this tutorial.

The model code has been open sourced on FlagAI and the weights are located on modelhub. We also provide scripts for fine-tuning, inference, and validation, so feel free to try them out.

阶段1使用平行语料库数据。

阶段2和3主要使用Laion-Aesthetics的一个子集。中文数据集采用wudaoMM数据集(CC-BY-SA 4.0)。

Stage 1 uses parallel corpus data.

Stage2&3 mainly use a subset of Laion-Aesthetics. The wudaoMM data set (CC-BY-SA 4.0) is used as a Chinese data set.
