Which of the following is a disadvantage of using convolutional neural networks for tabular time series data instead of a recurrent neural network? a) CNNs require less computational resources compared to RNNs. b) CNNs can effectively capture local patterns but may struggle with capturing long-term dependencies in the data. c) CNNs have a fixed input size, making them less flexible for handling varying sequence lengths. d) CNNs are more prone to overfitting compared to RNNs.
