Difference: 1. Open source means that the internal code of the system is completely open, and users can change or add corresponding functions according to their needs; non-open source means that the copyright belongs to the developer, and users do not know the source code content and cannot modify the source code. . 2. Those who are open source belong to the active side, and those who do not have open source belong to the passive side.
The operating environment of this tutorial: Windows 10 system, Dell G3 computer.
The difference between open source and non-open source
1. Different open permissions:
Open source means that the internal code of the system is completely open, and developers can set their own requirements version, which means that customers can extend the program according to their own needs and change or add corresponding functions according to their own ideas and needs. For example, if you perform secondary development on the source code, modify it, fix bugs, etc., the copyright can be marked as self-developed.
Not open source is the opposite. If you don’t know the source code content, you cannot modify the source code, etc. The copyright belongs to the developer.
2. Active and passive:
Open source belongs to the active party;
Unopen source belongs to the passive party.
For example: Linux is currently a completely open source operating system, which results in many Linux versions; while Windows is the opposite.
Open source, (Open Source) stands for open source code. Open source requires users to use the source code to modify and learn based on it, but open source systems also have copyrights and are also protected by law. There are endless open source software on the market. Many people may think that the most obvious feature of open source software is that it is free, but in fact this is not the case. The biggest feature of open source software should be openness, that is, anyone can obtain the source code of the software and modify it. Studying, or even redistributing, is of course within the limits of copyright.
Extended information:
Open source code is also called source code disclosure, which refers to a software release model. General software can only obtain compiled binary executable files, and usually only the author or copyright owner of the software owns the source code of the program.
The authors of some software will make the source code public, which is called "source code disclosure", but this does not necessarily meet the definition and conditions of "open source code" because the author may set the source code to be public. Conditional restrictions on the code, such as limiting the objects that can read the source code, limiting derivatives, etc.
Open source advantages:
The main advantages are reflected in long-term reliability, parallel debugging, parallel research and development, perfect application program interface, version release speed, etc. As far as long-term trustworthiness is concerned, as long as the enterprise will not be excluded from the competitive market in the short term, it can be called long-term trustworthiness. Since under the open source software development model, source code can be easily obtained from many places, and you can use and modify the source code yourself, you can further utilize the source code even if the software is no longer developed.
In addition, through the development of Internet technology, the open source software open model can adopt parallel debugging and parallel R&D practices, allowing potentially unlimited developers on the Internet to use them for free and at the same time. , not limited by time or geography, in the end you just need to choose a suitable solution, so as long as there are enough people participating, the source code release rate is usually faster;
As far as the perfect application program interface is concerned , the open source software development model will be based on the openness of the source code, allowing users to verify through the source code, unlike traditional closed source computer software that can only build its confidence on the image of the software company. The biggest advantage of the open source software development model is that it can be supported by a large number of open source communities, just like having a large number of free software developers and testers.
In this way, we can employ outstanding talents from all over the world without paying high salaries. This is something that cannot be obtained by the traditional closed source software development model.

作为一个技术博主,了不起比较喜欢各种折腾,之前给大家介绍过ChatGPT接入微信,钉钉和知识星球(如果没看过的可以翻翻前面的文章),最近再看开源项目的时候,发现了一个ChatGPTWebUI项目。想着刚好之前没有将ChatGPT接入过WebUI,有了这个开源项目可以拿来使用,真是不错,下面是实操的安装步骤,分享给大家。安装官方在Github的项目文档上提供了很多中的安装方式,包括手动安装,docker部署,以及远程部署等方法,了不起在选择部署方式的时候,一开始为了简单想着

5月2日消息,目前大多数AI聊天机器人都需要连接到云端进行处理,即使可以本地运行的也配置要求极高。那么是否有轻量化的、无需联网的聊天机器人呢?一个名为MLCLLM的全新开源项目已在GitHub上线,完全本地运行无需联网,甚至集显老电脑、苹果iPhone手机都能运行。MLCLLM项目介绍称:“MLCLLM是一种通用解决方案,它允许将任何语言模型本地部署在一组不同的硬件后端和本地应用程序上,此外还有一个高效的框架,供每个人进一步优化自己用例的模型性能。一切都在本地运行,无需服务器支持,并通过手机和笔

深度推荐模型(DLRMs)已经成为深度学习在互联网公司应用的最重要技术场景,如视频推荐、购物搜索、广告推送等流量变现业务,极大改善了用户体验和业务商业价值。但海量的用户和业务数据,频繁地迭代更新需求,以及高昂的训练成本,都对 DLRM 训练提出了严峻挑战。在 DLRM 中,需要先在嵌入表(EmbeddingBags)中进行查表(lookup),再完成下游计算。嵌入表常常贡献 DLRM 中 99% 以上的内存需求,却只贡献 1% 的计算量。借助于 GPU 片上高速内存(High Bandwidth

在人类的感官中,一张图片可以将很多体验融合到一起,比如一张海滩图片可以让我们想起海浪的声音、沙子的质地、拂面而来的微风,甚至可以激发创作一首诗的灵感。图像的这种「绑定」(binding)属性通过与自身相关的任何感官体验对齐,为学习视觉特征提供了大量监督来源。理想情况下,对于单个联合嵌入空间,视觉特征应该通过对齐所有感官来学习。然而这需要通过同一组图像来获取所有感官类型和组合的配对数据,显然不可行。最近,很多方法学习与文本、音频等对齐的图像特征。这些方法使用单对模态或者最多几种视觉模态。最终嵌入仅

刚刚,哥伦比亚大学系统生物学助理教授 Mohammed AlQuraishi 在推特上宣布,他们从头训练了一个名为 OpenFold 的模型,该模型是 AlphaFold2 的可训练 PyTorch 复现版本。Mohammed AlQuraishi 还表示,这是第一个大众可用的 AlphaFold2 复现。AlphaFold2 可以周期性地以原子精度预测蛋白质结构,在技术上利用多序列对齐和深度学习算法设计,并结合关于蛋白质结构的物理和生物学知识提升了预测效果。它实现了 2/3 蛋白质结构预测的卓

自从Midjourney发布v5之后,在生成图像的人物真实程度、手指细节等方面都有了显著改善,并且在prompt理解的准确性、审美多样性和语言理解方面也都取得了进步。相比之下,StableDiffusion虽然免费、开源,但每次都要写一大长串的prompt,想生成高质量的图像全靠多次抽卡。最近StabilityAI的官宣,正在研发的StableDiffusionXL开始面向公众测试,目前可以在Clipdrop平台免费试用。试用链接:https://clipdrop.co/stable-diff

在自动驾驶技术不断迭代的当下,车辆的行为和轨迹预测对高效、安全驾驶有着极为重要的意义。动力学模型推演、可达性分析等传统的轨迹预测的方法虽然有着形式明晰、可解释性强的优点,但在复杂的交通环境中,其对于环境和物体交互的建模能力较为有限。因此,近年来大量研究和应用都基于各种深度学习方法(例如 LSTM、CNN、Transformer、GNN 等),各类数据集例如 BDD100K、nuScenes、Stanford Drone、ETH/UCY、INTERACTION、ApolloScape 等也纷纷涌现
