Web3) For fits to more complicated models (e.g. a power-law over a cutoff power-law), the BAT team has decided to require a chi-square improvement of more than 6 for each extra dof. 4) For short bursts (T901sec), the specrtum is also fit with Blackbody, OTTB, and Double Blackbody. Time averaged spectrum fit using the pre-slew DRM Power-law model WebExample of splitting the output layers when batch_first=False: output.view(seq_len, batch, num_directions, hidden_size). Note. batch_first argument is ignored for unbatched inputs. Warning. There are known non-determinism issues for RNN functions on some versions of cuDNN and CUDA. You can enforce deterministic behavior by setting the following ...
