You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Consider a different scenario: an unknown nonlinear dynamical system is encapsulated into a blackbox and only an ensemble of trajectories (input and output data) are available. Comparing actual trajectories to interpolated trajectories is one way to gauge chaos. A typical method to interpolate from known trajectories is to build a surrogate model with machine learning techniques. A surrogate model needs to be established first, then predictions can be made by evaluating trajectories with given initial conditions. This procedure is known as "supervised learning" [2]. To validate the model, the **data** is often randomly split into two clusters: a large training set and a small testing set. A model is then constructed from the training set. The performance of the model, i.e., the prediction accuracy, is measured by comparing the testing **data** against its prediction. The performance of the model depends on the type and complexity of the model, the volume of training data, the algorithm used for training, etc.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
