自己动手打造AI Agent:基于DeepSeek-R1+websearch从零构建自己的Manus深度探索智能体AI-Research
第一章:AI Agent基础与DeepSeek-R1架构解析(1/10) 1.1 AI Agent技术演进与核心价值 人工智能代理(AI Agent)经历了从规则驱动到数据驱动的范式转移。早期基于专家系统的符号主义方法(如MYCIN医疗诊断系统)受限于知识库规模,而现代深度强化学习框架(如AlphaGo)通过环境交互实现了突破性进展。当前AI Agent的核心能力体现在: 认知架构:Transformer驱动的多模态理解 决策机制:基于PPO算法的动态策略优化 环境交互:API调用与物理设备控制接口 持续学习:Online Learning与Experience Replay技术 1.2 DeepSeek-R1模型架构深度剖析 DeepSeek-R1作为国产开源大模型代表,其混合架构融合了MoE(Mixture of Experts)与Transformer-XL的优势: class DeepSeekBlock(nn.Module): def __init__(self, dim, num_experts=8): super().__init__() self.attn =...
An Introduction to Ray: The Swiss Army Knife of Distributed Computing
Need a simple way to scale Python applications? Ray makes distributed computing easy for tasks like machine learning and data processing. Today, applications handle large datasets and complex tasks. To meet these demands, many frameworks for distributed computing have been developed to speed up processes and reduce delays. One such popular framework is Ray. Ray is a flexible tool designed for cloud-based distributed computing and for building scalable machine learning systems.
Linux Environments For Ai Training
Explore optimal Linux environments tailored for AI training, enhancing performance and efficiency for developers using AI tools. The framework for autonomous intelligence To effectively optimize Linux environments for AI training using DeepSpeed, it is crucial to focus on several key aspects that enhance performance and resource utilization.
In the early days of computing, applications handled tasks sequentially. As the scale grew with millions of users, this approach became impractical. Asynchronous processing allowed handling multiple tasks concurrently, but managing threads/processes on a single machine led to resource constraints and complexity. This is where distributed parallel processing comes in.

Dataframes With Big Data in Couchbase
If you have followed any tutorial on data science in Python, chances are that you have heard about a library known as Pandas. Pandas provides a dataframe interface for your data, which is a two-dimensional tabular data structure that "shares many properties with matrices" (in the words of `R`'s definition of dataframes). Dataframes have grown over the years to be an essential component of the modern data scientist’s toolkit.
大模型训练部署利器--开源分布式计算框架Ray原理介绍_ray serve.deployment-CSDN博客
目录 集群 remote方法 worker进程 参考 本文首先介绍Ray分布式的原理,对原理有了一定认识后,具体到使用就相对简单了,因此本文只会对使用做简要介绍,最后再说一下Ray的不足。文章的目的是让大家对Ray能有基本的了解,供大家判断Ray是否适合用于解决手头的问题。 Ray是什么? Ray是一个开源统一框架,为机器学习和大数据处理相关程序提供了用于并行处理的计算层,降低了大规模端到端机器学习工作流的开发难度。 Ray提供了在数据预处理、分布式训练、超参数调优、模型服务和强化学习几个方面的并行方法,分别对应上图的Data、Train、Tune、Serve和RLib模块,用户只需要在原有代码中新增几行代码,即可实现方法的并行操作。 同时,通过KubeRay可以将Ray程序很容易的移植到Kubernetes集群中,利用云原生生态中的基础能力对Ray任务进行更精细的管理。 如何做到分布式? Ray通常是以集群的方式部署在多台服务器上。Head node是主节点,Worker node是工作节点,上图展示了由1个Head node和2个Worker node组成的Ray集群。...
Is Python Ray the Fast Lane to Distributed Computing?
Python Ray is a dynamic framework revolutionizing distributed computing. Developed by UC Berkeley’s RISELab, it simplifies parallel and distributed Python applications. Ray streamlines complex tasks for ML engineers, data scientists, and developers. Its versatility spans data processing, model training, hyperparameter tuning, deployment, and reinforcement learning.
Empowering Distributed Compute in Cloudera Machine Learning with Ray
Chris Van Dyke☁️ Chris Van Dyke☁️ Published Feb 21, 2023 Lost in the talk about OpenAI is the tremendous amount of compute needed to train ChatGPT and GPT. Each iteration requires more compute and the limitation imposed by Moore's Law moves that task from single compute instances to distributed compute. To accomplish this, OpenAI has employed Ray to power the distributed compute platform to train ChatGPT and GPT.
Ray AI Runtime (AIR)
ML Compute, Simplified¶ Ray AIR aims to simplify the ecosystem of machine learning frameworks, platforms, and tools. It does this by leveraging Ray to provide a seamless, unified, and open experience for scalable ML: : AIR reduces friction going from development to production. With Ray and AIR, the same Python code scales seamlessly from a laptop to a large cluster.
