Synthetic data generation is a powerful tool that uses deep learning algorithms to create fake data that closely mirrors the patterns and distributions of real data. This approach is especially useful when real data is inaccessible due to compliance and privacy requirements.

You can generate synthetic data to replace real data, and it's often used in enterprises where the real data can't be changed or accessed. Synthetic data aims to replicate authentic data by reconstructing its statistical characteristics.

Synthetic data generators can produce any amount of data that closely mirrors the patterns, distributions, and interconnections observed in the real dataset. This is made possible by training the generator on genuine data.

Synthetic data not only allows the generation of analogous data but also enables the imposing of specific constraints on the data as necessary.

When generating synthetic data, it's essential to understand the types of synthetic data available to address a business issue.

There are two primary types of synthetic data: fully synthetic and partially synthetic.

Fully synthetic data is unrelated to actual or real-world data, making it unidentifiable.

Partially synthetic data retains all the original data except for sensitive information, which is removed to ensure confidentiality.

Synthetic data is revolutionizing industries with its numerous benefits. It's customizable to meet a business's unique requirements.

In the automotive industry, synthetic data can be produced to satisfy specific needs, such as creating datasets for vehicle collision analysis. This is more cost-effective than collecting actual data, which can be expensive and time-consuming.

A unique perspective: Use Cases of Generative Ai

Synthetic data generation with generative AI is a powerful tool that can create realistic data from scratch. It uses various techniques such as Generative Pre-trained Transformer (GPT) methodology, Generative Adversarial Networks (GANs), and Variational Auto-Encoders (VAEs) to generate synthetic data.

These models work by understanding and replicating patterns from the training data, making them valuable for augmenting tabular datasets and creating realistic tabular data for machine learning tasks. GANs, for instance, function on the interplay between "generator" and "discriminator" neural networks, where the generator produces synthetic data that mimics reality, while the discriminator distinguishes real data from synthetic data.

Here are the three main models used for synthetic data generation:

Synthetic data can be generated from scratch or built from an existing dataset, and it can be used for various purposes such as data augmentation and training machine learning models.

Generative AI creates synthetic data using deep machine learning (ML) generative models such as Generative Pre-trained Transformer (GPT), Generative Adversarial Networks (GANs), and Variational Auto-Encoders (VAEs).

These models can generate synthetic data that mimics real-world data, making them valuable for augmenting tabular datasets. GPT-based synthetic data generation tools can replicate patterns from the training data, creating realistic tabular data for ML tasks.

GANs, on the other hand, function on the interplay between a "generator" and a "discriminator" neural network. The generator produces synthetic data that attempts to deceive the discriminator, resulting in a high-quality synthetic dataset.

VAEs employ an "encoder" and a "decoder" to summarize patterns and characteristics present in real-world data and transform that summary into a lifelike synthetic dataset.

Synthetic data can be generated using computer simulations or algorithms, and it can be built from an existing dataset. The newly created data and the original data are almost exactly the same, making it possible to produce synthetic data of any size at any time and anywhere.

Generative AI can also create synthetic text by training a model on a large volume of text data. This technique is known as large language models, and it has become increasingly effective in generating realistic-looking synthetic writing.

One type of neural network used for synthetic text generation is the GPT-3 technique, which was trained on an enormous volume of text data. This technique has been used to create extraordinarily effective natural language generation systems.

Measuring the quality of synthetic data is crucial for its effectiveness in model training. It's often done through quantitative metrics, which provide a numerical score to evaluate the data.

There are three main perspectives to measure data quality: diversity, correctness, and naturalness. Diversity measures the difference between chunks of text in the generated instances, while correctness measures whether the data instance is related to the given label.

Automatic evaluation methods can be used to measure correctness, where a model is trained on the oracle training dataset and then applied to calculate the percentage of correctly predicted samples on the synthetic dataset.

Human evaluation is also used to measure naturalness, where human evaluators assess whether the generated text is fluent and similar to human-written texts by selecting a score from a given range.

A quality estimation module can be incorporated into the data generation pipeline to obtain high-quality synthetic data. This involves evaluating the first generated synthetic data using a task-specific model trained on oracle data, and then selecting the most influential samples as in-context examples to prompt GPT2-XL to generate new data.

Here are some key metrics to evaluate data quality:

Using high-quality synthetic data can improve the accuracy of machine-learning models by 10-15%, as found in a Stanford University study.
