pytorch中的grid_sample是一种特殊的采样算法。 调用接口为: torch.nn.functional.grid_sample(input,grid,mode='bilinear',padding_mode='zeros',align_corners=None)。 input参数是输入特征图tensor,也就是特征图,可以是四维或者五维张量,以四维形式为例(N,C,Hin,Win),N可以理解为Batch_size,C可以理解为通道数...

1. grid_sample函数的接口声明 torch.nn.functional.grid_sample(input, grid, mode='bilinear', padding_mode='zeros', align_corners=None) 在官方文档里面关于该函数的作用是这样描述的: Given an input and a flow-field grid, computes the output using input values and pixel locations from grid. ...
每一个分类器都需要一个scoring参数,或者score方法:如estimator = RandomForestClassifier(min_sample_split=100,min_samples_leaf = 20,max_depth = 8,max_features = 'sqrt' , random_state =10), 2)param_grid:需要最优化的参数的取值,值为字典或者列表,例如:param_grid = param_test1,param_test1 = {...
For values outside the input range, sample_mode is used to determine the value to use for the interpolation.Attributes sample_mode Controls how out-of-bound grid locations are evaluated: FILL Out-of-bound grid locations are assigned to 0. CLAMP Out-of-bound grid locations are assigned the ...
