advantages of Transformers Components Detection

Another crucial advantage is that deteriorations of the insulation level can be detected immediately. In a grounded system, fault currents can be resolved in the single-digit milliamp range by means of sophisticated ground-fault monitoring (RCM) technology – but no further. Even if it were possible to select only the ohmic portion of the residual current, this would imply detection of the deterioration of the

  • Object Detection With Transformers Using Facebook’s DETR

    Jul 16, 2020One of the main advantages of attention-based models is their global computations and perfect memory. Transformers were first used in auto-regressive models, following early sequence-to-sequence models, generating output tokens one by one. However, the prohibitive inference cost leads to the development of parallel sequence generation.
