The task of Grammatical Error Correction (GEC) has received remarkable attention with wide applications in Natural Language Processing (NLP) recent years. While one the key principles GEC is to keep correct parts unchanged and avoid over-correction, previous sequence-to-sequence (seq2seq) models generate results from scratch, which are not guaranteed follow original sentence structure may suffe...

Abstract. We present the generation and validation of an updated version TanDEM-X digital elevation model (DEM) Antarctica: PolarDEM 90 m Antarctica. Improvements compared to global DEM comprise filling gaps with newer bistatic synthetic aperture radar (SAR) acquisitions TerraSAR-X satellites, interpolation smaller voids, smoothing noisy areas, replacement frozen or open sea areas geoid undulat...
