前言

如今，只要随便进入一个网吧，都会发现玩《英雄联盟》的人是最多的，可以这么说，《英雄联盟》已经是当之无愧的端游一哥。而在拥有如此基数玩家的《英雄联盟》，已经不仅仅是一个电竞游戏这么简单了，它还带给了我们无数的欢乐。

问君能有几多愁，辅助闪现抢人头；问君能有几多愁，卡牌千里送人头。问君能有几多愁，皇子开大关队友；清明时节雨纷纷,各种队友各种坑。别人笑我不买眼,我笑别人浪费钱；孤帆远影碧空尽,草丛惊现蛮易信。相见时难别亦难，碰见赵信菊花残；我自横刀向天笑,剁人只需用三刀。苦练盲僧千百次, 盲目对战 N 多次；战输不下五十次, 砸得鼠标要出事；举杯邀明月,草丛遇盖伦。

前几天写了一篇关于吃鸡游戏的分析用 Python 分析了 1w 场吃鸡数据，原来吃鸡要这么玩！帮助小胖提升了吃鸡率。鉴于“二百斤灵魂”小胖舍友不仅痴迷于吃鸡类游戏，还非常喜欢 LOL，所以为了帮助他每天尽快拿到首胜，爬取并分析了 1982 余场 LOL 数据。非常神奇的是，在开局之前能够高概率的预测本局的胜负！让你提前做好心理准备。

分析和训练数据

利用神经网络（neural_network）、随机森林（random_forest）和支持向量机（support_vector）等若干智能算法进行训练和回归，最终进行比较效果。
