What are the major stages of an end-to-end workflow to build an NLP project with Vertex AI?

The major stages of an end-to-end workflow to build an NLP project with Vertex AI typically include Data Preparation, Model Training, and Model Serving.

Data Preparation is crucial as it involves gathering and pre-processing the text data that will be used to train the language model. This stage ensures that the data is in the right format and cleaned of any inconsistencies or noise that could negatively affect model performance. It might also include tasks like tokenization, stemming, and converting text into numerical formats suitable for model training.

Following data preparation, Model Training encompasses the process of selecting and training an algorithm on the prepared data. This stage is essential because it establishes the model's capability to make predictions or generate text based on the input it receives. It involves tuning hyperparameters, selecting the right architecture, and using techniques such as cross-validation to ensure that the model generalizes well to unseen data.

Model Serving is the final stage, where the trained model is deployed to a production environment. This step is critical as it looks at how the model will be accessed, including considerations for scalability, monitoring, and ongoing maintenance. In NLP applications, it may also involve setting up APIs to allow other applications to interact with the model for inference in real time.
