The project Adventure is a simple text-based adventure game. The game, as given, involves the hero trying to find his way from a deep dark forest to home and his true love. There s very little else the player can do apart from moving from place to place. It s not really very interesting.

书籍 Guide to Convolutional Neural Networks
General paradigm in solving a computer vision problem is to represent a raw image
using a more informative vector called feature vector and train a classifier on top of
feature vectors collected from training set. From classification perspective, there are
several off-the-shelf methods such as gradi ...
数据库系统 问题重述：有一个内含有大约40万条常用词汇的词库。现给定一篇文章
问题重述：有一个内含有大约40万条常用词汇的词库。现给定一篇文章，使用这个词库分析出常用词汇的出现次数，并按出现次数由高到低排序这些词语。
改进算法的思路：
1. 通常一篇文章所包含的词语远少于词库中40万的数量；
2. 数据库建立索引之后，可采用“二分法”对词语进行快速定位；
3. 逐字缩小查询范围，如果查询到某 ...
测试测量 ACPSO-SVR结合的非线性建模预测算法
提出一种基于自适应混沌粒子群优化和支持向量机结合的非线性预测建模算法（ACPSO-SVR），引入ACPSO启发式寻优机制对SVR模型的超参数进行自动选取，在超参数取值范围变化较大的情况下，效果明显优于网格式搜索算法。选取UCI机器学习数据库中的Forest fires标准数据集进行测试，实验结果表明该方法具有较高的精度和良好的泛化 ...
