In modern times, information in the form of data, is a critical asset. Data helps in improving, enhancing, developing, and strengthening of multiple industries worldwide.
What is Real Data
The actual and authentic observation of relevance is commonly called “real data’. This data is gathered by closely observing, analyzing, and documenting interactions, events, and behaviors that occur in the real world to carry out research and develop various industries, notably technology, healthcare, finance, and retail. Real data is composed of detailed information from financial transaction logs, medical records of patients, purchase histories of real-time customers, interactions of social media users, sensor readings from IoT devices, etc.
Challenges in using real data
While ‘real data’ is invaluable for its authenticity and relevance, it is not always the best option for training machines (an AI model) to learn.
Sharing actual data is subjected to ethical and legal limitations for organizations, as it contains personal information that makes it susceptible to data breaches. Organizations must follow the regulations in procuring data, as legislation such as the CCPA, GDPR, and HIPAA puts strict rules on the use and sharing of personal data, which makes real data collection costly and time-consuming.
What is ‘Synthetic Data’?
Synthetic data is derived from real data by carefully removing personal annotations and information such as name, personal IDs, and contact information (email, phone number, and address) using algorithms and datasets.
How does ‘Synthetic Data’ generated?
Organizations use advanced generation techniques such as GANs and VAEs to produce high-quality synthetic datasets, which ensures the building of resilient and effective AI systems.
Generative Adversarial Networks (GANs)
The generator and discriminator neural networks, together form the components of a GAN. The synthetic data is produced by the generator, and its accuracy is assessed by the discriminator.
Gradually learning from the discriminator’s feedback, the generator ultimately becomes more and more efficient in generating high-quality synthetic data that is virtually different from real data.
VAEs (Variational Auto Encoders)
VAEs encode real data into a latent space, which is subsequently decoded back into synthetic data, making them appropriate for training AI models by maintaining the statistical properties of the original dataset.
Rule-based Systems
For creating data from a specific framework like user interaction or money transactions, Rule-based systems work best. It’s a useful system for generating synthetic data as it is a pre-defined set of patterns and rules.
How Synthetic Data is processed to train AI models?
Synthetic data has become a critical component in training AI models; let’s find out how.
Preparation of Data
Synthetic data is pre-processed to satisfy the requirements of the training model. This entails separating the data into training and testing sets, cleaning it, and normalizing the values.
Model Training
The artificial intelligence model is trained with synthetic data. With the help of the artificial dataset, the model learns to identify patterns, make predictions, suggest actions, and carry out tasks.
Validation and testing
This step is a litmus test for an AI model’s accurate assessment and performance on hypothetical data. Only after crucial validations and performance checks for determining and distinguishing between synthetic and real data is the model said to be trained to go through.
The Obstacles in Processing Synthetic Data
Quality of Synthetic Data
The effectiveness of training AI models depends on the quality of the synthetic data. Poorly generated data can lead to biased or inaccurate models. Ensuring high-quality synthetic data requires sophisticated generation techniques and validation processes.
Computational Capabilities
To produce high-quality synthetic data, a lot of computing power may be needed, especially when using complex methods like GANs. For enterprises to develop and use synthetic data appropriately, they need a sufficient quantity of computational resources.
Validation through real data
Even though synthetic data is useful for training, AI models require real-world data validation to function successfully in real-world applications.
This step helps identify any discrepancies or issues that might arise from using only synthetic data.
The Future of Synthetic Data
In comparison with real-world data, synthetic data is smarter and extremely scalable. However, producing the correct synthetic data is a task in itself. A trained AI tool produces precise feedback if fed precise synthetic data.
It is well known that synthetic data aims at facilitating data scientists in accomplishing new and innovative things that will be tougher to achieve with real-world data, so you can surely assume that synthetic data is the future for sure.
Wrapping Up
In the end, the synthetic data is a useful resource for training AI models. It addresses a broad spectrum of peculiar and underrepresented circumstances.
Numerous advantages, such as improved privacy, affordability, scalability for extensive scenario coverage, and bias mitigation, increase the resilience and adaptability of AI models.
