  • The model achieved improved accuracy after completing ten epochs of training.
  • epoch file

But one epoch is the number of steps that matches the size of the training data.

Examples

  • For all the models, we used 35 epochs and 64 trajectories as the batch size.

  • And you can see that they're doing much, much better after many fewer epochs of training in doing this.

  • Spectral averaging was performed on the artifact-free epochs.

    Academic text (2006)
  • The heart rate monitors had a 15-s epoch length, yielding 120 data points per participant during each 30-min period.

    Academic text (2015)
  • Activity during each 30-second epoch was categorized as MVPA if total activity counts for the epoch were >1148, based on Evenson's cutpoints.

    Academic text (2012)
  • PA was assessed with accelerometers (Actigraph model GT1M, Pensacola, FL) using 30-s epoch recording intervals.

    Academic text (2014)
  • During each epoch, the network weights were adjusted based on the training data.

  • To optimize performance, we conducted multiple epochs over the entire dataset.

Etymology

The word epoch comes from the Greek epokhē, meaning 'a pause' or 'a fixed point'. In machine learning, an epoch is one full pass through the training data — one complete stage or cycle in the learning process.
