Interpretable Math Word Problem Solution Generation Via Step-by-step Planning

no code implementations1 Jun 2023 Mengxue Zhang, Zichao Wang, Zhichao Yang, Weiqi Feng, Andrew Lan

We propose a step-by-step planning approach for intermediate solution generation, which strategically plans the generation of the next solution step based on the MWP and the previous solution steps.

Attention-Based Second-Order Pooling Network for Hyperspectral Image Classification

1 code implementation IEEE Transactions on Geoscience and Remote Sensing 2021 Zhaohui Xue, Mengxue Zhang, Yifeng Liu, Peijun Du

On the other hand, the optimization of complex hyperparameters (e. g., the layer number and convolutional kernel size) is time-consuming and a very tough task, making the designed DL framework unexplainable.
