我最近做了一个艰难的决定: 博客重新开张
从今天起重新开始写博客。以后每天都要更新博客，不在乎文字的多少，也不在乎文笔怎么样。只把这里当做吐槽的地方，当作草稿纸。
Dynamic discrete choice vs. Markov decision process
因为现在做的工作和人的选择行为有关系, 于是先学现卖, 读了一些文献. 如果不考虑动态问题, 那么就是discrete choice model. 如果考虑动态的选择行为, 有好像有两类文章, 一类叫做 markov decision processes (MDP), 另一类叫做 dynamic discrete choice (DDC), 下面是这两方面的综述.
Rust J.的综述Structural estimation of markov decision processes
Eckstein Z.的综述The Specification and Estimation of Dynamic Stochastic Discrete Choice Models: A Survey
MDP的文章多是研究怎么求解最优策略, 如用dynamic programming. 而DDC的文章一般关注模型中参数的估计. 我想要做的是建立模型来求解最优策略, 但是我没有数据来检验模型到底行不行, 所以我怕我建立的模型根本就没法去估计.
Notes on sensitivity analysis and the combined travel demand model
1 Takashi Akamatsu, “Decomposition of Path Choice Entropy in General Transport Networks,” TRANSPORTATION SCIENCE 31 (4), 349-362 (1997). This paper shows that the conventional entropy function defined by path flows can be decomposed into a function consisting only of link flows. The equivalence of the decomposed formulation of the logit-based traffic assignment is proved by using [...]
