class_docstr: Compute `Accuracy`_ for binary tasks.
  
  .. math::
      \text{Accuracy} = \frac{1}{N}\sum_i^N 1(y_i = \hat{y}_i)
  
  Where :math:`y` is a tensor of target values, and :math:`\hat{y}` is a tensor of predictions.
  
  As input to ``forward`` and ``update`` the metric accepts the following input:
  
      - ``preds`` (:class:`~torch.Tensor`): An int or float tensor of shape ``(N, ...)``. If preds is a floating
        point tensor with values outside [0,1] range we consider the input to be logits and will auto apply sigmoid
        per element. Additionally, we convert to int tensor with thresholding using the value in ``threshold``.
      - ``target`` (:class:`~torch.Tensor`): An int tensor of shape ``(N, ...)``
  
  As output to ``forward`` and ``compute`` the metric returns the following output:
  
      - ``acc`` (:class:`~torch.Tensor`): If ``multidim_average`` is set to ``global``, metric returns a scalar value.
        If ``multidim_average`` is set to ``samplewise``, the metric returns ``(N,)`` vector consisting of a scalar
        value per sample.
  
  If ``multidim_average`` is set to ``samplewise`` we expect at least one additional dimension ``...`` to be present,
  which the reduction will then be applied over instead of the sample dimension ``N``.
  
  Args:
      threshold: Threshold for transforming probability to binary {0,1} predictions
      multidim_average:
          Defines how additionally dimensions ``...`` should be handled. Should be one of the following:
  
          - ``global``: Additional dimensions are flatted along the batch dimension
          - ``samplewise``: Statistic will be calculated independently for each sample on the ``N`` axis.
            The statistics in this case are calculated over the additional dimensions.
  
      ignore_index:
          Specifies a target value that is ignored and does not contribute to the metric calculation
      validate_args: bool indicating if input arguments and tensors should be validated for correctness.
          Set to ``False`` for faster computations.
  
  Example (preds is int tensor):
      >>> from torch import tensor
      >>> from torchmetrics.classification import BinaryAccuracy
      >>> target = tensor([0, 1, 0, 1, 0, 1])
      >>> preds = tensor([0, 0, 1, 1, 0, 1])
      >>> metric = BinaryAccuracy()
      >>> metric(preds, target)
      tensor(0.6667)
  
  Example (preds is float tensor):
      >>> from torchmetrics.classification import BinaryAccuracy
      >>> target = tensor([0, 1, 0, 1, 0, 1])
      >>> preds = tensor([0.11, 0.22, 0.84, 0.73, 0.33, 0.92])
      >>> metric = BinaryAccuracy()
      >>> metric(preds, target)
      tensor(0.6667)
  
  Example (multidim tensors):
      >>> from torchmetrics.classification import BinaryAccuracy
      >>> target = tensor([[[0, 1], [1, 0], [0, 1]], [[1, 1], [0, 0], [1, 0]]])
      >>> preds = tensor([[[0.59, 0.91], [0.91, 0.99], [0.63, 0.04]],
      ...                 [[0.38, 0.04], [0.86, 0.780], [0.45, 0.37]]])
      >>> metric = BinaryAccuracy(multidim_average='samplewise')
      >>> metric(preds, target)
      tensor([0.3333, 0.1667])
