Introduction to SynthGPT
SynthGPT is a specialized AI tool designed to generate synthetic time series data with configurable parameters. Its primary purpose is to assist in creating time series data for testing, modeling, and analysis, offering users full control over characteristics like trend, seasonality, noise, autocorrelation, and Concept Drift. SynthGPT is built to handle both univariate and multivariate time series, making it highly flexible for diverse data modeling needs. By adjusting parameters, users can simulate complex real-world phenomena in a controlled environment. For example, it can be used to simulate stock prices over time with fluctuating trends and varying market volatility, or it can mimic seasonal sales data with periodic spikes and random noise.
Main Functions of SynthGPT
Synthetic Time Series Generation
ExampleA data scientist can generate a time series that simulates daily temperature readings over a year, incorporating seasonal patterns (with peaks in summer and troughs in winter), noise, and gradual warming trends.
ScenarioThis function is useful when testing forecasting models or validating algorithms before deploying them on real-world climate data.
Custom Parameter Configuration
ExampleA user could specify a multivariate time series with three variables, such as sales, marketing spend, and customer engagement over time, each with its own autocorrelation, trend, and noise factors. One variable could exhibit Concept Drift, representing a sudden market shift.
ScenarioThis feature allows businesses to simulate how various factors (e.g., marketing strategies) impact sales over time, enabling them to better anticipate changes in customer behavior.
Concept Drift Simulation
ExampleA machine learning engineer can generate a time series representing an IoT sensor, where the data suddenly shifts in pattern due to device recalibration (Concept Drift). The parameters for trend, noise, and autocorrelation before and after the shift can be finely tuned.
ScenarioThis is ideal for stress-testing anomaly detection algorithms or adaptive systems that need to respond to unexpected data changes in environments like industrial IoT.
Ideal Users of SynthGPT
Data Scientists and Machine Learning Engineers
These users benefit from SynthGPT when testing models, as they require well-defined, customizable time series data to validate machine learning algorithms under various conditions like seasonality, noise, and Concept Drift. This allows for improved model robustness before deployment in real-world applications.
Quantitative Analysts and Financial Engineers
Quantitative analysts can simulate stock prices, economic indicators, or portfolio performance with custom trends, volatility, and autocorrelation factors. The ability to simulate shocks or market shifts through Concept Drift is especially valuable in risk modeling and financial forecasting.

Q&A About SynthGPT
What kind of time series data can SynthGPT generate?
SynthGPT generates synthetic time series data with customizable features like multivariate dimensions, trends, seasonality, noise, and Concept Drift. Users can specify parameters such as sampling frequency and the number of timesteps to suit their use case.
How does SynthGPT handle Concept Drift?
Concept Drift is integrated by allowing abrupt or gradual changes in time series parameters over time. You can specify which variables experience Concept Drift and whether the change is sudden or progressive.
Can I generate both univariate and multivariate time series?
Yes, SynthGPT supports the generation of both univariate and multivariate time series. You can define the number of variables and their relationships, including autocorrelations and inter-variable correlations.
What are the common applications for using synthetic time series data from SynthGPT?
SynthGPT is often used for testing algorithms, simulating scenarios for predictive analytics, benchmarking time series forecasting models, and academic research where real-world data is either unavailable or incomplete.
What output formats does SynthGPT provide?
The generated synthetic time series data can be visualized as graphs and exported as CSV files, making it easy to integrate the data into analytical or machine learning workflows.
