accuracy¶

dragon.metrics.accuracy(
  inputs,
  axis=- 1,
  top_k=1,
  ignore_index=None,
  **kwargs
)[source]¶

Compute the top-k accuracy.

Parameters:

• inputs (Sequence[dragon.Tensor]) – The tensor logit and label.
• axis (int, optional, default=-1) – The axis to reduce, can be negative.
• top_k (int, optional, default=1) – The top-k accuracy to compute.
• ignore_index (int, optional) – The ignored value of target.

Returns:

dragon.Tensor – The output tensor.
