Training AI Safely with Synthetic Data
Training artificial intelligence (AI) models requires vast amounts of data to achieve accurate results. However, using real data poses significant risks to privacy and regulatory compliance. To address these challenges, synthetic data has emerged as a viable alternative.
These are artificially generated datasets that mimic the statistical characteristics of real data, allowing organizations to train their AI models without compromising individual privacy or violating regulations.
Regulatory Compliance, Privacy, and Data Scarcity
Regulations around the use of personal data have become increasingly strict, with laws such as the General Data Protection Regulation (GDPR) in Europe and the California Consumer Privacy Act (CCPA) in the United States.
This approach to data provides a solution for training AI models without putting personal information at risk, as it does not contain identifiable data, yet remains representative enough to ensure accurate outcomes.
Use Cases for Synthetic Data
The impact of this technology extends across multiple industries where privacy protection and a lack of real-world data present common challenges. Here’s how this technology is transforming key sectors:
Financial
In the financial sector, the ability to generate artificial datasets allows institutions to improve fraud detection and combat illicit activities. By generating fictitious transactions that mirror real ones, AI models can be trained to identify suspicious patterns without sharing sensitive customer data, ensuring compliance with strict privacy regulations.
For instance, JPMorgan Chase employs synthetic data to bypass internal data-sharing restrictions. This enables the bank to train AI models more efficiently while maintaining customer privacy and complying with financial regulations.
Healthcare
In the healthcare sector, this approach is crucial for medical research and the training of predictive models. By generating simulated patient data, researchers can develop algorithms to predict diagnoses or treatments without compromising individuals’ privacy. Synthetic data replicates the necessary characteristics for medical analyses without the risk of privacy breaches.
For instance, tools like Synthea have generated realistic synthetic clinical data, such as SyntheticMass, which contains information on one million fictional residents of Massachusetts, replicating real disease rates and medical visits.
Automotive
Synthetic data is playing a crucial role in the development of autonomous vehicles by creating virtual driving environments. These datasets allow AI models to be trained in scenarios that would be difficult or dangerous to replicate in the real world, such as extreme weather conditions or unexpected pedestrian behavior.
A leading example is Waymo, which uses this method to simulate complex traffic scenarios. This allows them to test and train their autonomous systems safely and efficiently, reducing the need for costly and time-consuming physical trials.
Generating and Using Synthetic Data
The generation of synthetic data relies on advanced techniques such as generative adversarial networks (GANs), machine learning algorithms, and computer simulations. These methods allow organizations to create datasets that mirror real-world scenarios while preserving privacy and reducing the dependence on sensitive or scarce data sources.
Synthetic data can also be scaled efficiently to meet the needs of large AI models, enabling quick and cost-effective data generation for diverse use cases.
For example, platforms like NVIDIA DRIVE Sim utilize these techniques to create detailed virtual environments for autonomous vehicle training. By simulating everything from adverse weather conditions to complex urban traffic scenarios, NVIDIA enables the development and optimization of AI technologies without relying on costly physical testing.
Challenges and Limitations of Synthetic Data
One of the main challenges is ensuring that synthetic data accurately represents the characteristics of real-world data. If the data is not sufficiently representative, the trained models may fail when applied to real-world scenarios. Moreover, biases present in the original data can be replicated in synthetic data, affecting the accuracy of automated decisions.
Constant monitoring is required to detect and correct these biases. While useful in controlled environments, synthetic data may not always capture the full complexity of the real world, limiting its effectiveness in dynamic or complex situations.
For organizations in these sectors, partnering with a specialized technology partner may be key to finding effective, tailored solutions.
The Growing Role of Synthetic Data
Synthetic data is just one of the tools available to protect privacy while training AI. Other approaches include data anonymization techniques, where personal details are removed without losing relevant information for analysis. Federated learning, which enables AI models to be trained using decentralized data without moving it to a central location, is also gaining traction.
The potential for synthetic data extends beyond training models. These data can be used to enhance software validation and testing, simulate markets and user behavior, or even develop explainable AI applications, where models can justify their decisions based on artificially generated scenarios.
As techniques for generating and managing synthetic data continue to evolve, this data will play an even more crucial role in the development of safer and more effective AI solutions.
The ability to train models without compromising privacy, along with new applications that leverage artificially generated data, will allow businesses to explore new opportunities without the risks associated with real-world data.

Do you Know the Difference Between Data Engineering vs Data Science?
Belonging to the world of technology involves hearing many concepts that may sound similar to each other. And one of them may be data engineering vs. data science. Although they share some similarities, the reality is that there are many important differences between them.
For this reason, the purpose of this article is to inform you and let you know what each concept means. Read on and find out more about the difference between data engineering vs data science!
Data engineering vs Data Science: what are the similarities and differences between the two terms?
Well, to learn more about data engineering vs. data science, it is necessary to know that in the world of technology and data there are many professions and roles. Precisely, this is the main shared characteristic between both concepts: both the engineer and the data scientist are constantly working with large volumes of Big Data.
However, the difference is in the purpose. Engineers are in charge of extracting large volumes of information and organizing databases. On the other hand, data scientists perform visualization tasks, diagramming learning tasks, and patterns on the data previously extracted by engineers.
For this reason, the tools used by each tend to vary. In the case of data scientists, they usually use resources such as Deep Learning, Machine Learning, data processors (such as Spark), or programming tools such as R or Python. In this way, engineers use databases such as SQL and NoSQL, the Hadoop ecosystem, and tools such as Apache Airflow or Dagster.
It should be made clear that both are indispensable professions for any company that wants to take advantage of technology. However, this serves only as an introduction to the subject. For this reason, we recommend that you read on to find out more about each of these fields of work.
What does data engineering consist of?
Let’s specify a little bit the roles that are practiced in data engineering. According to Coursera, it is the practice of designing and building systems that collect and store large volumes of data. Therefore, the engineer is the person who is responsible for building and maintaining data structures for use in multiple applications.
The ultimate goal of the data engineer is to make all this data accessible for the organization to consider in decision-making. In other words, the idea is that this data is transformed into useful information that executives can use to maximize profits and see growth in the company.
It is for this reason that a data engineer must have advanced knowledge of databases. Likewise, as there is a trend towards cloud programming, he or she needs to know all these systems. This professional must also be able to work in conjunction with different departments, to understand the organization’s objectives.
So, it is key to understand that data engineers will not only need to be passionate about programming. They will also need to have communication skills, as they will be working in conjunction with other departments and professionals, as is the case with data scientists.
And what specifically is Data Science?
Now, you may want to know more details about data scientists, which is another of the most sought-after professions by companies in recent years. IBM considers that data science combines knowledge in mathematics, statistics, programming, and artificial intelligence, to make efficient decisions and improve the company’s strategic planning.
It should be noted that Data Science is not synonymous with Artificial Intelligence. In reality, a data scientist uses Artificial Intelligence to extract useful information from unstructured data. AI is a series of algorithms that mimic human intelligence to read and understand data, but it is the scientist who makes the final decision.
This situation means that the data scientist has to be a person with a strong sense of logic. Not only will they have to work by studying the behavior of the data, but they will have to understand what the company wants. For this reason, they must not only master statistical software and programming but also have a strong interest in market and company situations.
Similarly, it should be considered that the data scientist will not only obtain data from a single source, as a traditional data analyst would do. Here they will seek to have a global perspective of the problem. Although they will bring their subjectivity to include their point of view in the decision-making process, the objective data will reinforce their arguments.
In short, you have seen that understanding the difference between data engineering vs data science is not complicated at all. Both professions are essential to working with Big Data since taking advantage of large volumes of information is key to achieving great results in a company. We hope this article has cleared up your doubts!

Data is a vital resource for any organization. Managing business data requires a careful and standardized process. We have already discussed in previous articles the life cycle of data and how it can help your company in making business decisions. This is why today we propose to take another step into the world of data and understand what types of data companies like yours work with.
Database management problems are often related to tight behaviors in the organization. That is to say, inconveniences with the treatment of the data that arise from the use of outdated, inefficient technologies that consume many organizational resources. This translates into a high dependency between the programs used and the data, little flexibility in administration, difficulty in sharing data between applications or users, data redundancy, and poor information security.
But even in advanced technology companies, it is common to find the same limitation: staff does not understand the types of data they are working with and have difficulty transforming the data into key knowledge relevant for decision making. And with the advancement of Big Data in companies, these problems represent a loss of value for customers, employees, and stakeholders.
Data in companies: different structures.
Everyday companies collect (and generate) a lot of data and information. With the advancement of technology, data that lacks a defined structure became accessible and of great use for making business decisions; years ago, it was almost impossible to analyze these data in a standardized and quantitative way. Let’s see what the alternatives we face are:
- Structured data. They are traditional data, capable of being stored in tables made up of rows and columns. They are located in a fixed field of a specific record or file. The most common examples are spreadsheets and traditional databases (for example, databases of students, employees, customers, financial, logistics…).
- Semi-structured data. These do not follow a fixed and explicit scheme. They are not limited to certain fields, but they do maintain markers to separate items. Tags and other markers are used to identify some of its elements, but they do not have a rigid structure. We can mention XML and HTML documents, and data obtained from sensors as examples. Some other not-so-traditional examples that we could mention are the author of a Facebook post, the length of a song, the recipient of an email, and so on.
- Unstructured data. They are presented in formats that cannot be easily manipulated by relational databases. These are usually stored in data lakes, given their characteristics. Any type of unstructured text content represents a classic example (Word, PowerPoint, PDF files, etc.). Most multimedia documents (audio, voice, video, photographs) and the content of social media posts, emails, and so forth, also fall into this category.
How do I structure my data?
Beyond the level of structure discussed above, it is essential to your organization’s data management process that you can standardize its treatment and storage. For that, a fundamental concept is that of metadata: data about data. It sounds like a play on words, but we mean information about where data is used and stored, the data sources, what changes are made to the data, and how one piece of data refers to other information. To structure a database we have to consider four essential components: the character, the field, the record, and the file. So we can understand how our data is configured …
- A character is the most basic element of logical data. These are alphabetic, numeric, or other-type symbols that make up our data. For example, the name PAUL consists of four characters: P, A, U, L.
- The field is the grouping of characters that represents an attribute of some entity (for example, data obtained from a survey, from a customer data management system, or an ERP). Continuing with the previous example, the name PAUL would represent a complete field.
- The record is a grouping of fields. Represents a set of attributes that describe an entity. For example, in a survey, all responses from Paul (a participant) represent one record (also known in some cases as a “row”).
- Last but not least, a file is a group of related records. If we continue with Paul’s example, we could say that the survey data matrix is an example file (whether it is encoded in Excel, SQL, CSV, or whatever format it is). Files can be classified based on certain considerations. Let’s see some of them:
The application for which they are used (payroll, customer bases, inventories …). |
The type of data they include (documents, images, multimedia …). |
Its permanence (monthly files, annual sets …). |
Its possibility of modification (updateable files –dynamic, modifiable-, historical –means of consultation, not modifiable). |
As you have seen, the world of data is exciting and you can always continue learning concepts and strategies to take advantage of its value in your organization. To close this article and as a conclusion and example of the value of data for companies, we want to invite you to learn about a project in which we work for one of our clients. The General Service Survey that we develop for Aeropuertos Argentinos is an application of the entire life cycle of data (from its creation to its use) and is fed with data of different levels of structure. It is about the development of a platform to carry out surveys to visitors and employees, together with the analysis and preparation of automated reports. Don’t miss this case study!
