Predictions of Neural Network for $\beta$-decay half-lives

# The predictions of $\beta$-decay half-lives by neural network# Meanings of headers: #   Z: proton number; #   N: neutron number; #   log_T: the logarithm of beta-decay half-life predictions in the unit of second; #   log_T_err: the logarithm error bars of the beta-decay half-life predictions in the unit of second;
