TorchMetrics documentation. TorchMetrics is a collection of Machine learning metrics for distributed, scalable PyTorch models and an easy-to-use API to create custom metrics. It offers the following benefits: Optimized for distributed-training. A standardized interface to increase reproducibility. Reduces Boilerplate.
sklearn.metrics.auc(x, y) [source] ¶. Compute Area Under the Curve (AUC) using the trapezoidal rule. This is a general function, given points on a curve. For computing the area under the ROC-curve, see roc_auc_score. For an alternative way to summarize a precision-recall curve, see average_precision_score. Parameters.
auc [func]¶ torchmetrics.functional. auc (x, y, reorder = False) [source] Computes Area Under the Curve (AUC) using the trapezoidal rule. Parameters. x¶ (Tensor) – x-coordinates, must be either increasing or decreasing. y¶ (Tensor) – y-coordinates. reorder¶ (bool) – if True, will reorder the arrays to make it either increasing or ...

sklearn.metrics.auc(x, y)[source]¶. Compute Area Under the Curve (AUC) using the trapezoidal rule. This is a general function, given points on a curve.
Tensor containing AUC score (float) Raises: ValueError: If both ``x`` and ``y`` tensors are not ``1d``. ValueError: If both ``x`` and ``y`` don't have the same numnber of elements. ValueError: If ``x`` tesnsor is neither increasing or decreasing. Example: >>> from torchmetrics.functional import auc >>> x = torch.tensor([0, 1, 2, 3])
... Operating Characteristic Curve (ROC AUC) accumulating predictions and the ground-truth during an epoch and applying sklearn.metrics.roc_auc_score .
If the mode of data (binary, multi-label, multi-class) changes between batches. "Metric `AUROC` will save all targets and predictions in buffer." " For large datasets this may lead to large memory footprint." """Update state with predictions and targets.
class torchmetrics. AUC (reorder = False, compute_on_step = True, dist_sync_on_step = False, process_group = None, dist_sync_fn = None) [source] Computes Area Under the Curve (AUC) using the trapezoidal rule. Forward accepts two input tensors that should be 1D and have the same number of elements. Parameters
Specify the process group on which synchronization is called. default: None (which selects the entire world) Callback that performs the ``allgather`` operation on the metric state. When ``None``, DDP. will be used to perform the ``allgather``. "Metric `AUC` …

when pytorch<1.8.0, numpy will be used to calculate this metric, which causes sdr to be ... Computes AUC based on inputs passed in to update previously.
AUC¶ class torchmetrics. AUC (reorder = False, compute_on_step = True, dist_sync_on_step = False, process_group = None, dist_sync_fn = None) [source] Computes Area Under the Curve (AUC) using the trapezoidal rule. Forward accepts two input tensors that should be 1D and have the same number of elements. Parameters
ROC_AUC. Computes Area Under the Receiver Operating Characteristic Curve (ROC AUC) accumulating predictions and the ground-truth during an epoch and applying sklearn.metrics.roc_auc_score . output_transform ( Callable) – a callable that is used to transform the Engine ’s process_function ’s output into the form expected by the metric.
30.03.2020 · Actually there is. Using the sklearn function involves the necessity to convert from torch.Tensor to numpy.ndarray before converting. While this is totally fine on cpu (no memory copy made here), this really causes a slow-down for gpu tensors, since it involves a GPU-sync.
