Sub‐Grid Representation of Vegetation Cover in Land Surface Schemes Improves the Modeling of How Climate Responds to Deforestation

open access: yesGeophysical Research Letters, Volume 50, Issue 15, 16 August 2023., 2023
Abstract Understanding the regional climate response to land cover change requires a realistic sub‐grid representation of vegetation cover in the land surface scheme (LSS) of climate models. The Community Land Model (CLM) is considered one of the most advanced LSSs; however, when coupled with the Weather Research and Forecasting (WRF) model, the tiling

A high speed reconfigurable architecture for softmax and GELU in vision transformer

open access: yesElectronics Letters, Volume 59, Issue 5, March 2023., 2023
This work proposes a high speed reconfigurable accelerator, which can support both softmax and GELU functions in ViT by reconfiguring the data path. Experimental results show that the design can achieve a very small accuracy loss in ViT's inference. Compared with the existing designs, this design has higher throughput and area efficiency and is more ...
