    Hyper Parameters and Setting for LinearChainCrf training

    Hyper Parameters and Setting for LinearChainCrf training


    \- Minimum number of epochs to train


    \- Maximum number of epochs to train


    \- l2 regularization coefficient


    \- Initial number of steps in decay strategy


    \- If loss after a SGD epochs haven't improved (absolutely) more than lossEps, then training is stopped


    \- Seed for random


    \- Level of verbosity during training procedure
