擴充 AI 和 Python 應用程式:Ray 是開放原始碼架構,可擴充 AI 和 Python 應用程式。Ray 提供基礎架構,可為機器學習 (ML) 工作流程執行分散式運算和平行處理。
Vertex AI 中的 Ray 經過精心設計,可讓您使用相同的開放原始碼 Ray 程式碼編寫程式,並在 Vertex AI 上開發應用程式,只需進行極少的變更。然後,您可以使用 Vertex AI 與其他 Google Cloud 服務的整合功能 (例如 Vertex AI Inference 和 BigQuery),做為機器學習 (ML) 工作流程的一部分。

MLOps is a set of practices\nthat improves the stability and reliability of your ML systems.\n\nVertex AI MLOps tools help you collaborate across AI teams and improve your\nmodels through predictive model monitoring, alerting, diagnosis, and actionable\nexplanations. All the tools are modular, so you can integrate them into your\nexisting systems as needed.\n\nFor more information about MLOps, see [Continuous delivery and automation\npipelines in machine learning](/architecture/mlops-continuous-delivery-and-automation-pipelines-in-machine-learning) and the [Practitioners Guide to MLOps](https://services.google.com/fh/files/misc/practitioners_guide_to_mlops_whitepaper.pdf).\n\n- **Orchestrate workflows**: Manually training and serving your models\n can be time-consuming and error-prone, especially if you need to repeat the\n processes many times.\n\n - [Vertex AI Pipelines](/vertex-ai/docs/pipelines/introduction) helps you automate, monitor, and govern your ML workflows.\n- **Track the metadata used in your ML system**: In data science, it's\n important to track the parameters, artifacts, and metrics used in your ML\n workflow, especially when you repeat the workflow multiple times.\n\n - [Vertex ML Metadata](/vertex-ai/docs/ml-metadata/introduction) lets you record the metadata, parameters, and artifacts that are used in your ML system. You can then query that metadata to help analyze, debug, and audit the performance of your ML system or the artifacts that it produces.\n- **Identify the best model for a use case**: When you try new training algorithms,\n you need to know which trained model performs the best.\n\n - [Vertex AI Experiments](/vertex-ai/docs/experiments/intro-vertex-ai-experiments) lets you track and analyze\n different model architectures, hyper-parameters, and training environments\n to identify the best model for your use case.\n\n - [Vertex AI TensorBoard](/vertex-ai/docs/experiments/tensorboard-introduction) helps you track, visualize, and\n compare ML experiments to measure how well your models perform.\n\n- **Manage model versions**: Adding models to a central repository helps you\n keep track of model versions.\n\n - [Vertex AI Model Registry](/vertex-ai/docs/model-registry/introduction) provides an overview of your models so you can better organize, track, and train new versions. From Model Registry, you can evaluate models, deploy models to an endpoint, create batch inferences, and view details about specific models and model versions.\n- **Manage features**: When you re-use ML features across multiple teams, you\n need a quick and efficient way to share and serve the features.\n\n - [Vertex AI Feature Store](/vertex-ai/docs/featurestore/latest/overview) provides a centralized repository for organizing, storing, and serving ML features. Using a central featurestore enables an organization to re-use ML features at scale and increase the velocity of developing and deploying new ML applications.\n- **Monitor model quality**: A model deployed in production performs best on\n inference input data that is similar to the training data. When the input\n data deviates from the data used to train the model, the model's performance\n can deteriorate, even if the model itself hasn't changed.\n\n - [Vertex AI Model Monitoring](/vertex-ai/docs/model-monitoring/overview) monitors models for training-serving skew and inference drift and sends you alerts when the incoming inference data skews too far from the training baseline. You can use the alerts and feature distributions to evaluate whether you need to retrain your model.\n- **Scale AI and Python applications** : [Ray](https://docs.ray.io/en/latest/ray-overview/index.html) is an open-source framework for scaling AI and Python applications. Ray provides the infrastructure to perform distributed computing and parallel processing for your machine learning (ML) workflow.\n\n - [Ray on Vertex AI](/vertex-ai/docs/open-source/ray-on-vertex-ai/overview) is designed so you can use the same open source Ray code to write programs and develop applications on Vertex AI with minimal changes. You can then use Vertex AI's integrations with other Google Cloud services such as [Vertex AI Inference](/vertex-ai/pricing#prediction-prices) and [BigQuery](/bigquery/docs/introduction) as part of your machine learning (ML) workflow.\n\nWhat's next\n-----------\n\n- [Vertex AI interfaces](/vertex-ai/docs/start/introduction-interfaces)"]]
