         x (Tensor): A `5D` tensor with shape :math:`(N, C, D, H, W)`, where `N` is the batch size, `C` is the number
             of channels, `D` is the feature depth, `H` is the feature height, and `W` is the feature width.
             The data type must be int8, int16, int32, int64, float16, float32 or float64.
-        p (float): The keeping probability of a channel, between 0 and 1, e.g. `p` = 0.8,
+        p (float): The dropping probability of a channel, between 0 and 1, e.g. `p` = 0.8,
             which means dropping out 80% of channels. Default: 0.5.
 
     Returns:
-        output (Tensor): With the same shape and data type as `x`.
-        mask (Tensor): With the same shape as `x` and the data type is bool.
+        Tensor, output, with the same shape and data type as `x`.\n
+        Tensor, mask, with the same shape as `x` and the data type is bool.
 
     Raises:
         TypeError: If `x` is not a Tensor.
