通过近似最近邻索引（已在向量搜索抢先体验计划中实现）加快向量搜索速度

#Natural Language Processing #Vector Search #Graph #Performance #Early Access Program (EAP) #Testing #Indexing #InterSystems IRIS #InterSystems IRIS for Health #InterSystems Official

我们最近在向量搜索抢险体验计划中提供了新版的 InterSystems IRIS，新版本采用了新的基于分层可导航小世界 (HNSW) 索引算法的近似最近邻索引。 这一新增功能可对大型向量数据集进行高效的近似最近邻搜索，从而显著提高查询性能和可扩缩性。

HNSW 算法旨在通过构建基于图形的结构来优化高维数据的向量搜索，从而更快地在大型向量集合中找到近似邻。 无论您使用的是推荐系统、自然语言处理，还是其他机器学习应用，HNSW 都能显著缩短搜索时间，同时允许您调整准确度水平，但准确度提高的代价是查询时间变慢。

HNSW 的主要优点包括：

第四十一章 创建安全对话 - 使用 SecurityContextToken

第四十一章 创建安全对话 - 使用

在 Web 服务使用 <SecurityContextToken>, 做出响应后，客户端实例和服务实例可以访问相同的对称密钥。有关此密钥的信息包含在两个实例的 SecurityContextToken 属性中。建议的程序如下：

  1. 在客户端中，将 SecurityOut 属性设置为 null，以删除请求消息中使用的安全标头。

在 Web 服务中不需要这样做，因为 Web 服务会在每次调用后自动清除安全标头。

VS Code release September 2024 (version 1.94)

#Development Environment #George James Software #ObjectScript #Python #Studio #VSCode #Other

Visual Studio Code releases new updates every month with new features and bug fixes, and the September 2024 release is now available. 

Version 1.94 now includes: 

  • Find in Explorer - Quickly find files in the Explorer view with the improved Find control. As a consequence of this, the Explorer's Find widget on server-side folders requires v2.12.9-beta.4 or later with Proposed APIs enabled. Read more in this Developer Community post. 
  • Source Control Graph - More filtering options and interactivity in the Source Control Graph.
  • Python test coverage - Run Python tests with coverage and get rich results in the editor.
  • ESM - Faster VS Code startup thanks to the migration to ESM.
  • Account preference - Specify which account to use for an extension.
  • Copilot in Native REPL - Get code completions and Inline Chat in the Native REPL.
  • Improved chat context - Drag & drop files or use IntelliSense for more relevant chat context.
  • Test environment setup - Get help with setting up a test framework for your workspace.

 

The release also includes contributions from our very own @John Murray through pull requests that address open issues. 

Find out more about these features in the release notes here > https://code.visualstudio.com/updates/v1_94

For those with VS Code, your environment should auto-update. You can manually check for updates by running Help > Check for Updates on Linux and Windows or running Code > Check for Updates on macOS.

If you're thinking about migrating from Studio to VS Code but need some help, take a look at the training courses George James Software offers > georgejames.com/vscode-training/
