关于人工神经网络的一点心得
2015-10-25 18:39
几年前我在这里写过一篇 博客 ,讲的是如何从比赛结果倒推比赛规则。这是一个典型的从数据当中揭示规律的问题。现在学了一些新的东西,对之前这个问题又有了新的认识。 主要是学到了“人工神经网络(artificial neural network)” 这个东西,了解到它可以“重现”大多数的函数。当然,多数是连续函数。那么它对不连续 ...

Disputation on evol-cancer research 02
2012-11-19 23:58
A common issue that many evol-cancer researchers are focusing on is the effect of micro-environment on cells when talking about competition among somatic cells and their strategies, but I don't think it's the most essential one to be emphasized. An intuitive argument is, if a bunch/lineage of soma ...

2012-11-14 11:18
本来不准备在这个博客上谈学术以外的事情,不过发现上面的“记录”所能记录的东西实在太少。 有些人有本事,有见地,有他自己的成功之道,并且过着世人皆醉我独醒的日子。但是他们不懂得体谅别人的难处,不懂得并不是所有人都像他们自己一样。 一个人可以清高,但不能要求别人都跟他一样清高。 大家都还是要挣钱,吃饭, ...

My current knowledge/ideas in evolutionary cancer research
