Introduction

In this article, we will explore how to utilize Gretel's new synthetic text data quality report. If You have ever used a GPT model, you may wonder how to assess the quality or utility of the natural language synthetic data it outputs. We have created a report with metrics and scores to help you understand the data's quality, and in this article, we will guide you through the process.

Understanding Gretel's Synthetic Text Data Quality Report

Before we dive into the details, let's understand what Gretel's synthetic text data quality report is all about. The report provides an easy-to-digest overview of the synthetic data's quality and includes various metrics to measure its similarity to the training data. It combines the text semantic similarity and text structure similarity scores to give you a comprehensive understanding of the synthetic data's quality.

Generating Natural Language Text using GPT

To get started with Gretel's synthetic text data quality report, you will need to generate natural language text using the GPT model. The process is simple and can be done through the Gretel dashboard at console.gretel.ai. By selecting the "generate natural language text using GPT" option, you can start generating synthetic data.

Uploading a Data Source

If you have a specific data source you want to use, you can upload it to the Gretel dashboard. However, if you don't have a data source readily available, Gretel also provides a sample dataset that you can use to get started. For example, you can upload a dataset of Amazon dress reviews to train the GPT model.

Model Configuration

Once you have selected or uploaded a dataset, it's time to configure the GPT model. In most cases, the default configuration works well, so you don't need to make any changes. The pre-trained Gradow AI MTV 7 billion parameter model is commonly used and serves as an excellent starting point for generating synthetic text.

Training the GPT Model

With the dataset and model configuration set, you can begin training the GPT model. The model starts training Based on the dataset you provided, and you can monitor the progress and check the logs on the Gretel dashboard. The training process may take some time, so be patient.

Checking Training Progress and Logs

During the model training, it's essential to keep an eye on the training progress and logs. The Gretel dashboard provides updates on the progress and any messages related to the training and generation process. By regularly checking the logs, you can ensure everything is running smoothly.

Downloading the Model and Previewing the Report

Once the training is complete, you can download the model and preview the synthetic data quality report. The report gives you a quick overview of the overall score, semantic similarity scores, and structure score. Additionally, you can download a preview of the synthetic data itself to get a visual representation.

Analyzing the Synthetic Text Quality Report

Now let's Delve deeper into the synthetic text quality report and understand the metrics it provides. The report includes the overall score, which combines semantic similarity and text structure similarity. We will explore the meaning behind the score, how semantic similarity is calculated, and how the synthetic and training data compare using principal component analysis.

Additionally, the report presents the distribution of the text structure, including sentence count, words per sentence, and characters per word. These distributions help you understand how closely the synthetic data aligns with the training data.

Conclusion

In this article, we have explored Gretel's synthetic text data quality report and its usefulness in assessing the quality and utility of synthetic data generated by GPT models. By understanding the metrics and scores provided in the report, you can confidently use synthetic data for your machine learning models. Generate synthetic data, analyze the report, and make informed decisions about the quality of your data.
