Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
Parameterized optimization problems (POPs) belong to a class of NP problems which are hard to be tackled by traditional methods. However, the relationship of the parameters (usually represented as k) makes a POP different from ordinary NP-complete problem in designing algorithms. In this paper, ...
Computing Variance under Interval Uncertainty: An Example of an NP-Hard ProblemFormulation of the problem : reminder . In many practical applications, we need to estimate the sample variance V = \\\(\\\frac{1}{n}\\\) · \\\(\\\sum\\\limits^{n}_{i=1}{(x_{i} - E)}^{2}\\...

It can be hard to stay up-to-date on the published papers in the field of adversarial examples, where we have seen massive growth in the number of papers written each year. I have been somewhat religiously keeping track of these papers for the last few years, and realized it may be ...
maximum(0, np.round(start / step)).astype(int) end = np.minimum(chunk_annotations["end"], chunk.end) - chunk.start - half end_idx = np.round(end / step).astype(int) # get list and number of labels for current scope labels = list(np.unique(chunk_annotations[label_scope_key]))...
Complexity of Equilibria 在zero-sum game中,Nash Equilibria可以在多项式时间内被计算出来,例如可以使用线性规划,甚至是一些简单的迭代模型。 而在其他的non-zero-sum game中,纳什均衡是不存在多项式时间的解法的,但是也并非是NP-hard的问题,而是一个PPAD-hard(Polynomial Parity Arguments on Directed graphs)的问题。
The main structure in Keras is the Model which defines the complete graph of a network. You can add more layers to an existing model to build a custom model that you need for your project. Here’s how to make a Sequential Model and a few commonly used layers in deep learning ...
Travelling Salesman is a classic NP hard problem, which this notebook solves with AWS SageMaker RL. Tic-tac-toe is a simple implementation of a custom Gym environment to train and deploy an RL agent in Coach that then plays tic-tac-toe interactively in a Jupyter Notebook. Scientific Details...
