pygtrie is a Python library implementing a trie data structure. Trie data structure, also known as radix or prefix tree, is a tree associating keys to values where all the descendants of a node have a common prefix (associated with that node). The trie module contains Trie, CharTrie and...
PyBrain 是 Python-Based Reinforcement Learning, Artificial Intelligence and Neural Network Library 的缩写。我们将利用一个简单的例子来展示 PyBrain 的用法,构建一个多层感知器 (Multi Layer Perceptron, MLP)。首先,我们创建一个新的前馈网络对象: frompybrain.structureimp...
Another core library for scientific computing is SciPy. It is based on NumPy and therefore extends its capabilities. SciPy main data structure is again a multidimensional array, implemented by Numpy. The package contains tools that help with solving linear algebra, probability theory, integral calculus...
