英文摘要：
In Chinese societies, superstition is of paramount importance, and vehicle license plates with desirable numbers can fetch very high prices in auctions. Unlike other valuable items, license plates are not allocated an estimated price before auction. I propose that the task of predicting plate prices can be viewed as a natural language processing (NLP) task, as the value depends on the meaning of each individual character on the plate and its semantics. I construct a deep recurrent neural network (RNN) to predict the prices of vehicle license plates in Hong Kong, based on the characters on a plate. I demonstrate the importance of having a deep network and of retraining. Evaluated on 13 years of historical auction prices, the deep RNN\'s predictions can explain over 80 percent of price variations, outperforming previous models by a significant margin. I also demonstrate how the model can be extended to become a search engine for plates and to provide estimates of the expected price distribution.

中文摘要：
在中国社会，迷信是最重要的，数字合适的车牌在拍卖中可以卖到很高的价格。与其他贵重物品不同的是，车牌在拍卖前不分配估计价格。我认为预测车牌价格的任务可以看作是一项自然语言处理（NLP）任务，因为其值取决于车牌上每个字符的含义及其语义。我构建了一个深度递归神经网络（RNN）来预测香港车牌的价格，基于车牌上的字符。我证明了拥有深厚的人际网络和再培训的重要性。根据13年的历史拍卖价格进行评估，deep RNN的预测可以解释80%以上的价格变化，大大优于以前的模型。我还演示了如何将该模型扩展为车牌搜索引擎，并提供预期价格分布的估计。

分类信息：

一级分类：Computer Science 计算机科学
二级分类：Computation and Language 计算与语言
分类描述：Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.
涵盖自然语言处理。大致包括ACM科目I.2.7类的材料。请注意，人工语言（编程语言、逻辑学、形式系统）的工作，如果没有明确地解决广义的自然语言问题（自然语言处理、计算语言学、语音、文本检索等），就不适合这个领域。
