dropout¶

dragon.nn.dropout(
  inputs,
  ratio=0.5,
  inplace=False,
  **kwargs
)[source]¶

Set the elements of input to zero randomly. [Srivastava et.al, 2014].

The Dropout function is defined as:

\[\text{Dropout}(x) = x * (r \sim \mathcal{B}(1, 1 - \text{ratio})) \]

Examples:

x = dragon.ones((2, 3), 'float32')
print(dragon.nn.dropout(x, ratio=0.5))

Parameters:

• inputs (dragon.Tensor) – The input tensor.
• ratio (Union[float, dragon.Tensor], optional, default=0.5) – The probability to zero an element.
• inplace (bool, optional, default=False) – Call in-place or return a new tensor.

Returns:

dragon.Tensor – The output tensor.
