What is Synthetic Data?
Synthetic data refers to artificially generated datasets that closely resemble real-world datasets in terms of their statistical properties and distributions. It is created by applying mathematical models and algorithms to existing datasets or by generating entirely new datasets based on predefined rules.
There are different types of synthetic data generation techniques available:
1) Rule-based synthesis: This technique involves defining rules or constraints based on which the synthetic dataset is generated. For example, if we want to create a dataset representing customer transactions, we can define rules such as transaction amount should follow a normal distribution with specific mean and standard deviation.
2) Model-based synthesis: In this approach, statistical models are used to generate synthetic datasets that mimic the patterns observed in real-world datasets. These models can range from simple regression models to complex deep learning architectures.
3) Hybrid synthesis: This technique combines both rule-based and model-based approaches for generating synthetic datasets. It allows for more flexibility in capturing complex relationships present in the original dataset while still adhering to predefined rules.
How Synthetic Data is Generated
There are several techniques available for generating synthetic data:
1) Generative Adversarial Networks (GANs): GANs are a popular technique for generating synthetic data. They consist of two neural networks - a generator network and a discriminator network. The generator network generates synthetic data, while the discriminator network tries to distinguish between real and synthetic data. Through an iterative process, both networks improve their performance, resulting in high-quality synthetic data.
2) Variational Autoencoders (VAEs): VAEs are another type of neural network-based approach for generating synthetic data. They consist of an encoder network that maps real-world data into a lower-dimensional latent space and a decoder network that reconstructs the original data from the latent space. By sampling from the latent space, VAEs can generate new instances of realistic-looking synthetic data.
3) Data augmentation: Data augmentation involves applying various transformations or modifications to existing real-world datasets to create new instances of synthetic data. This technique is commonly used in computer vision tasks where images are flipped, rotated, or distorted to increase the diversity and size of the dataset.
When comparing these techniques for generating synthetic data, each has its advantages and limitations. GANs and VAEs offer more flexibility in capturing complex relationships present in the original dataset but require significant computational resources and expertise to train effectively. On the other hand, rule-based synthesis techniques are simpler but may not capture all nuances present in real-world datasets.
