Top 14 Synthetic Data Generation Tools in 2024

PR Newswire reports 79% of global executives and 75% of business users to face data quality issues based on a survey of 1000+ executives and managers. Further, 69% of executives believe that data regulations hinder decision-making and call for better data management tools.

Organizations can solve such issues through Synthetic Data. Indeed, Gartner predicts that by 2024, 60% of data used in Artificial Intelligence (AI) and analytics will be synthetic.

But what exactly is synthetic data? And what tools can organizations use to generate it? This article answers such questions and discusses some other aspects of synthetic data.

What is Synthetic Data?

Synthetic data is artificially generated that follows real-world patterns. Analysts can train AI and Machine Learning (ML) algorithms on real-world data and then use them to create synthetic or fake data. Synthetic data helps users build robust applications where real data is lacking. 

In today’s digital age, companies must shift to synthetic data to assure customers that their information is in safe hands.

Benefits of Synthetic Data

Synthetic data has several benefits over actual data. 

Data Quality

Actual data can come in with several inaccuracies and errors that bog down the performance of data-driven applications. For example, real data may have a systematic bias, such as a dataset having an underrepresentation of a certain ethnic group. 

However, once analysts have a synthetic data model, they can generate a clean and new dataset without such issues.

Scalability

Analysts can use a synthetic data tool to generate as many data points as they want. 

Often, companies cannot scale up ML applications due to the low availability of quality data for training and testing purposes. Synthetic data can help as it is a viable substitute for real data, and there is no limit to its volume.

Security

Companies cannot collect or store sensitive data due to strict privacy laws. But they can overcome the difficulty by generating fake data resembling the actual one.

For example, organizations can generate fake customer data with all the necessary details like income, preferences, credit card history, etc. Since all of it is fake, there's no danger of breaching any law or cybercrime threats, such as data theft.

Cost-Effective

Since all a company needs is some actual data and a data generation tool, synthetic data is cost-effective for collecting data. It requires no extra devices, focus groups, surveys, questionnaires, or purchase of expensive data from third-party sellers. 

More Controllable

Analysts have more control over synthetic data. They can change their data-generating models to suit new circumstances and get more relevant data that reflect the latest conditions.

Synthetic Data Generation Methods

Analysts can generate synthetic data using some state-of-the-art methods involving neural networks. Data scientists can create and train models based on the neural network architecture that can effectively learn non-linear distributional patterns of real data.

Generative Adversarial Networks (GAN)

GANs have become a famous unsupervised learning method for generating fake data and also for reinforcement and semi-supervised learning tasks. The algorithm architecture consists of two neural networks. One is called the generator, and the other is called the discriminator. 

The generator generates fake data, and the discriminator tells if the simulated data differs from the real one. With several thousand iterations, the discriminator cannot tell the difference as the generator produces very realistic synthetic data. 

GANs are useful when analysts want to generate fake image data. But they can use it to generate numerical data also.

Variational Autoencoders (VAE)

VAEs are unsupervised algorithms that learn patterns from the original data's distribution and "encode" the information in a latent distribution. The algorithm then maps or "decodes" it onto the original space and computes a "reconstruction error." 

The objective is to minimize reconstruction error. The method is suitable for continuous data that have well-defined distributions.

Neural Radiance Field (NeRF) 

NeRF takes a partially known 3-dimensional (3D) scene and generates new views. The neural network uses static images from the scene and then adds new view angles of the same scene. However, the algorithm is slow and may produce low-quality images.

Challenges of Synthetic Data

Despite its benefits, generating synthetic data takes longer than it seems. There are several challenges that analysts face when working with synthetic data models.

Costly Models

Synthetic data generation requires complex models and expensive hardware that are costly to build and maintain.

Such costs are a hindrance for smaller organizations that don’t have the budget to invest in the required technology.

Accuracy vs. Realism

Data scientists can test the accuracy of synthetic data by comparing it with real data. However, if the real data itself has flaws, then no matter how great the accuracy is, synthetic data will be low-quality. 

Privacy vs. Relevance

Finally, Personally Identifiable Information (PII) can be relevant for several analyses. Synthetic data generators remove PII to maintain privacy, which can be a problem for users who want to work with such information.

How to choose Synthetic Data Tools

Synthetic data tools can help solve some of the challenges mentioned earlier. But with so many tools available in the market, it often becomes overwhelming. Technical details make it even more challenging to understand how a particular tool processes synthetic data behind the scenes. So to make things easier, below is a list of some factors that you can consider before making a purchase.

Business Requirement: Businesses must clearly define the reason for which they require synthetic data. It largely depends on the industry in which the business operates. For example, a retailer may have a different requirement for synthetic data than a healthcare professional. 

A retailer may want a generator that can replicate transactional data, while a healthcare provider may want a tool that is good at understanding clinical data for patients.

Types of Synthetic Data: Synthetic data can be categorical, like gender data, numerical, like age data, or an image. Users need specialized tools to generate each type of data. There isn't a single tool that can do it all.

Cost: A company has three options for generating synthetic data. It can either create a generation algorithm in-house, get an open-source solution, or buy from a vendor. Building in-house solutions can be not only time-consuming but resource-intensive as well if it requires a business to hire experts. Open-source tools are easy to customize but challenging to implement and can trigger privacy issues. An out-of-the-box tool is easy to implement and learn due to vendor support but offers less customization. 

A business must therefore weigh the pros and cons of each option carefully. The following section lists the top 15 third-party synthetic data tools companies can consider if they want to buy from a vendor.

From Synthetic Data to Production

Synthetic data provides input for several applications, including ML products and services. However, synthetic data is just one component in the ML production lifecycle. After data scientists build and test a model, it goes into the hands of ML engineers, who deploy the model in the actual customer's environment. 

The deployment process can be long and frustrating. KDNuggets’ poll suggests that data scientists fail to deploy more than 80% of ML models. Challenges may include incompatible production environments, latency, disconnect between the engineering and data science teams, use of different tools to create and deploy models, etc.

Several tools are available to automate and streamline deployment to overcome such difficulties. Qwak is one tool that simplifies the process of bringing ML models to production at scale. 

Qwak simplifies the productionization of machine learning models at scale. Qwak’s Feature Store and ML Platform empower data science and ML engineering teams to Build, Train and Deploy ML models to production continuously.
