To evaluate deep learning's classification capabilities on extensive datasets and its noise tolerance , a chaotic two-dimensional (2D) image classification algorithm using a convolutional neural network is introduced. 1D time series from circuit and laser chaotic systems are transformed into 128 × 128 grayscale images to create a diverse dataset. A four-layer convolutional neural network (CNN) then classifies seven types of chaos, then results show that the system achieves an accurate chaos classification rate of up to 99.56 %. This paper also examines the impact of network depth, noise intensity, and image pixel size on performance. With a four-layer network, the system shows higher accuracy and lower performance loss. Adding Gaussian noise with a variance of 0.1 still maintains accuracy above 98.5 %. Increasing image resolution to 128 × 128 pixels results in a stable accuracy of 99.3 %. Overall, the system demonstrates strong robustness and generalization ability.
