# Decision Transformer model trained on expert trajectories sampled from the Gym HalfCheetah environment
This is a trained [Decision Transformer](https://arxiv.org/abs/2106.01345) model trained on expert trajectories sampled from the Gym HalfCheetah environment.

The following normlization coeficients are required to use this model:

mean = [ -0.04489148,  0.03232588,  0.06034835, -0.17081226, -0.19480659, -0.05751596,  0.09701628,  0.03239211, 11.047426,   -0.07997331, -0.32363534,  0.36297753,  0.42322603,  0.40836546,  1.1085187,  -0.4874403,  -0.0737481 ] 

std = [0.04002118,  0.4107858, 0.54217845,  0.41522816, 0.23796624, 0.62036866, 0.30100912,  0.21737163, 2.2105937, 0.572586, 1.7255033, 11.844218, 12.06324,     7.0495934,  13.499867, 7.195647, 5.0264325]
