实际上,这个项目是在ChatPaper的基础上进行的更新,采用了最近由Google开源的Gemini Pro大模型。这样一来,我们可以免费使用ChatPaper,并且未来我还计划加入对论文图片的读取以提取摘要(测试结果是OK的),大家可以关注一下https://github.com/Kedreamix/ChatPaperFree
目前,我们能够对用户输入的论文进行自动总结。未来,我还计划加入对论文图片/表格/公式的识别 extraction,从而生成更全面而易读的总结。如果在对话中chatbot能提供更优质的服务,我还会尝试进行更深层次的模型fine-tuning。我会在后续尝试进行更新,大家也可以提出自己的意见,也欢迎提PR。这是ChatPaper的GitHub链接,多多关注。
另外,为了跟上快速发展的人工智能领域和庞大的arxiv论文,我们从arXiv爬取了大量论文,并制作了网站进步屋使研究人员能够便捷获取当前热点。通过Gemini Pro对论文进行自动归纳,我们可以用极少的文本来展示论文要点,帮助用户快速评估哪篇值得深入研读。
在这个不断变化的时代,ChatPaperFree GeminiPro通过利用强大技术,有效提升我们学习效率。同时,我们也欢迎你提供关键词,共同完善这个平台,让每个人都能在技术演进中取得新的进步。(可在https://github.com/wmpscc/ipaper.today提出关键词,欢迎)
希望未来,我们可以搭建更友好的人机合作模式。
我已经部署到了HuggingFace上了,大家都可以尝试用一下,看看怎么样 https://huggingface.co/spaces/Kedreamix/ChatPaperFree
pip install -r requriements.txt
python app.py
成功后,进入http://127.0.0.1:7860即可,接着就可以输入自己的API key。
Google的Gemini Pro的API key是免费的,所以大家都是可以申请的,具体申请可以在https://makersuite.google.com/进行获取,每个人都可以获取多个,如果大家有自己的一些想法,也可以看谷歌的API使用文档https://ai.google.dev/tutorials/python_quickstart。
实际上,这个操作与ChatPaper的爬取论文类似,我们通过爬取最新arxiv论文,根据设定的关键词,每天对论文进行爬取,以最快的速度跟踪最新的文章。实验室已经搭建了一个网站,大家可以多多支持,提出自己的关键词,我们会不定时进行更新,让你每天都能看到最新的文章。
这是进步屋的网站:进步屋 https://ipaper.today/ ,大家如果有什么需要学习的内容,可以给出关键词,在GitHub提issue。
后续,我还计划加入自动生成摘要和分析的功能,包括尝试让数字人播报等等,敬请期待。
最近,我还会尝试生成文章的简单摘要,丰富内容,这是即将上线的由GPT生成简单摘要的部分,后续还可以加入更多功能,比如ChatPaper的prompt,我猜可以得到更好的效果。

Recent advancements in 3D reconstruction from single images have been driven by the evolution of generative models. Prominent among these are methods based on Score Distillation Sampling (SDS) and the adaptation of diffusion models in the 3D domain. Despite their progress, these techniques often face limitations due to slow optimization or rendering processes, leading to extensive training and optimization times. In this paper, we introduce a novel approach for single-view reconstruction that efficiently generates a 3D model from a single image via feed-forward inference. Our method utilizes two transformer-based networks, namely a point decoder and a triplane decoder, to reconstruct 3D objects using a hybrid Triplane-Gaussian intermediate representation. This hybrid representation strikes a balance, achieving a faster rendering speed compared to implicit representations while simultaneously delivering superior rendering quality than explicit representations. The point decoder is designed for generating point clouds from single images, offering an explicit representation which is then utilized by the triplane decoder to query Gaussian features for each point. This design choice addresses the challenges associated with directly regressing explicit 3D Gaussian attributes characterized by their non-structural nature. Subsequently, the 3D Gaussians are decoded by an MLP to enable rapid rendering through splatting. Both decoders are built upon a scalable, transformer-based architecture and have been efficiently trained on large-scale 3D datasets. The evaluations conducted on both synthetic datasets and real-world images demonstrate that our method not only achieves higher quality but also ensures a faster runtime in comparison to previous state-of-the-art techniques.

We introduce an approach that creates animatable human avatars from monocular videos using 3D Gaussian Splatting (3DGS). Existing methods based on neural radiance fields (NeRFs) achieve high-quality novel-view/novel-pose image synthesis but often require days of training, and are extremely slow at inference time. Recently, the community has explored fast grid structures for efficient training of clothed avatars. Albeit being extremely fast at training, these methods can barely achieve an interactive rendering frame rate with around 15 FPS. In this paper, we use 3D Gaussian Splatting and learn a non-rigid deformation network to reconstruct animatable clothed human avatars that can be trained within 30 minutes and rendered at real-time frame rates (50+ FPS). Given the explicit nature of our representation, we further introduce as-isometric-as-possible regularizations on both the Gaussian mean vectors and the covariance matrices, enhancing the generalization of our model on highly articulated unseen poses. Experimental results show that our method achieves comparable and even better performance compared to state-of-the-art approaches on animatable avatar creation from a monocular input, while being 400x and 250x faster in training and inference, respectively.
