基于深度学习算法的脉冲类调制信号智能识别方案设计

脉冲类调制在空间光领域得到了广泛应用,但深度学习算法用于脉冲类调制信号的智能识别却鲜有报道。针对传统识别算法的场景局限性和特征提取的人工分析依赖性,文章利用深度学习网络构建了一种通信信号特征自主学习算法,并通过拟合短时傅里叶变换的两种计算机制分别构建了基于CRBM和RBM的通信信号特征学习网络。相比基于CRBM的网络,基于RBM的网络的计算速度较快,且有效降低了深度学习网络对高性能硬件的要求。

学习党史担负未来

In order to celebrate the 100th anniversary of the Communist Party of China,Shenzhen LuoHu Middle School organized different kinds of events.The purpose of the activities is to guide the majority of young people to deepen the love for CPC, the country and the society so that the red gene and revolutionary fire will be passed on from generation to generation. We have carried out a series of online and offline activities on“tracing the history of Luohu Bridge”. We first collected some information on the Internet, and then went to Liantang Port and Luohu Railway Bridge to visit Luohu Bridge at a close distance. We knew the history of Luohu Bridge. Liu Guoan,the captain of the army, showed us some history of Luohu Bridge.

基于“乐享平台”的名师工作室混合式跨校教研模式探究

疫情时期,针对当前教研的困局——教研活动停滞、组织规模较小、专业引领不够等,本研究提出基于教育信息化、旨在优势互补的线上线下混合式教研,通过系统化设计赋能名师工作室学科教研,即对教研活动的主题、内容、形式、评价进行整体设计,建立长程化的教研模式,关注个性化需求,促进线上线下教研的深度融合。同时,建立跨校教研的命运共同体,以合理的组织架构、明确的组织目标、有力的组织制度、清晰的运作程序,激发教师主体更积极主动的参与和交互,最终实现教师的共同成长。
