Description

Introduction

Natural Language Processing (NLP) is crucial for extracting insights from text data. With Vertex AI and AutoML Natural Language, Google Cloud enables users to build, train, and deploy custom NLP models for classification, sentiment analysis, and entity extraction—using minimal code or fully customizable workflows.

Prerequisites

• Familiarity with basic machine learning concepts

• Experience with Python (optional but helpful)

• A labeled text dataset (CSV or JSONL format)

• Google Cloud project with Vertex AI and AutoML API enabled

• IAM roles: Vertex AI Admin, Storage Admin
