Description: Chua Oscillator varying alpha, beta, gamma of canonical dimensionless equations (see for example, Ch 3 of Bilotta, E., & Pantano, P. (2008). A Gallery Of Chua Attractors, World Scientific. - This dataset is derived from the DE64 example in that book). This set could be challenging to model because of the nonlinear relationship between parameters and audio. Although the parameters are grid sampled, the audio data characteristics are not balanced. The parameters explore the space between pitched and noisy sounds. A few sounds are not strictly textures because they are bistable and make a single switch from one from one to the other attractor. If you look at DSChua.py, you'll see a datastructure with 150 parameter sets for different Chua attractors. You can generate datasets for them by editing the config_file.

Parameters:

• alpha : 9 values mapped to n in [6.2, 7], where n -> coefficient
• beta : 9 values mapped to n in [10.25, 11], where n -> coefficient
• gamma : 9 values mapped to n in [-0.2, -0.045], where n -> coefficient
