Discrete Optimization: beyond REINFORCE by Kevin Shen

WebIn fact, the Gumbel-Softmax trick naturally translates to structured variables when argmax operator is applied over a structured domain rather than component-wise [34]. In contrast, score function estimators are now less common in structured domain, with a few exceptions such as [50, 14]. The WebWargames are essential simulators for various war scenarios. However, the increasing pace of warfare has rendered traditional wargame decision-making methods inadequate. To address this challenge, wargame-assisted decision-making methods that leverage artificial intelligence techniques, notably reinforcement learning, have emerged as a promising … change windows picture user

Loss function for Gumble Softmax - PyTorch Forums

WebUnfortunately, sampling generated points z from the softmax distribution given by the LSTM, eq. (1), is not differentiable with respect to the hidden states h (and thus ). However, the Gumbel-softmax distribution, eq. (4) is. Equipped with this trick we can take any differentiable loss function and optimize and using gradient-based techniques. We 3 WebThe inverse cumulative density function (ICDF; also called quantile function) is given by F 1(u) = log( logu)+ : (6) From Eq. (6) it can be seen that the Gumbel distribution is closed under scaling and addition, i.e. any Gumbel variable can be generated by scaling and shifting a standard Gumbel. Equation (6) is used in inverse transform ... WebFirst, we adopt the Gumbel- softmax [11] trick to make the retrieval process differentiable, thus enable op- timizing the embedding through the end-to-end training.
