微博上有朋友让推荐概率与统计课,刚才回得有些简短,这里可以多写一些。

这门课程也是今年春节后跟的,和Codecademy相似,每天我会看一两个视频或做几个练习,这样虽然每天的量很少,但是持续下来这门课也快学完了,目前在Kehan上的积分是接近11万分,不过可汗学院上看一个视频或者做一套练习就可以拿750分,也不算多,但是我相信持续积累的力量。

回到这门课,可汗老师基本上在白板上边写边讲,通俗易懂,另外一个就是它的配套练习系统了,没有一定的正确率是不让你通过的。网易公开课虽然有这门课的视频,但是缺少了练习,好像就丢了魂。虽然以前在学校里学过概率和统计,特别是后者,感觉很多基本概念没有在脑子中留下印记。这门课刚好给我补回了很多基本的概念,有些概念我会再查一下wiki,配合着一些有趣的视频让后在我的英文博客上凑一篇笔记,这样印象就更深刻了。感兴趣的同学可以看这里Kehan Academy Notes
