一种基于胶囊网络的图像检索方法
作为一种新兴的网络结构,胶囊网络用向量输出替代标量输出,能够捕捉图像特征之间的空间关系,改善卷积神经网络的局限性。首先对胶囊网络进行训练实现图像分类,得到图像的预测类标签,判定出查询图像的所属类别,然后将网络的数字胶囊层中的特征参数作为图像的特征向量,在查询图像的所属类别集合中利用图像特征向量找到与查询图像相似的图像。分别在FASHION-MNIST和 …

基于Angstrom-Prescott模型和空间插值的山东省月太阳辐射再估算
基于Angstrom-Prescott模型和空间插值法构建了山东省各地的月太阳辐射估算方法,并利用山东省3个国家站(济南、莒县和福山)和菏泽、聊城、淄博及青岛的辐射观测数据验证了估算方法的准确性。首先利用山东省3个国家站1992年—2015年的辐射与日照百分率观测数据,采用最小二乘法拟合得到不同月份Angstrom-Prescott模型系数并以2016年观测 …
