基于单星观测的双损失函数弹道估计方法
Science Technology and Engineering（2013）
Northwestern Polytechnical University
Abstract
针对没有标准弹道模板先验信息支持的情况下,单星观测弹道估计问题中观测信息不全,无法直接进行弹道估计,并且在使用残差大小作为优化标准,收敛不确定问题,提出了采用双损失函数的确定性弹道估计方法。利用基于观测量的损失函数和基于高度偏差的损失函数联合搜索确定弹道中两点高度,从而确定弹道平面方向,保证系统确定地收敛到最优解。通过数值仿真验证了算法的有效性。

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
