中文简介:
如果语言学家和计算科学家能够找到有意义的共同点,那么这个小组的结尾是不确定的。正如会议组织者迈克尔科恩最初所说,“我们讨论的问题与红袜队一样对人们来说是宗教性的。”这两个学科以独特的方式看待他们共同的领域,在这个小组和随后的讨论中,导致了一些摩擦。主持人Charles Yang总结了之前的会谈,描述了主持人如何探讨诸如统计模型是否能够充分捕捉心理和语言复杂性以及学习模型是否符合发展数据等问题。他引用了持续的难题,例如“孩子如何做一些显然与数据中的内容相矛盾的事情”,他希望在语法统计学习的讨论中看到这一点.Robert Friedin评论道,“我注意到了什么在建模者的演示中,提出的句法表示不是我接受的句法表征。在语言学中有一种假设,语言具有特定的句法结构,而不是另一种。 如果你有一套语法理论可以为你提供正确的句法表示,你可能想说,让我们接受它,现在让我们看看我们需要添加什么来解释外围的其他事情。“Jean Roger Vergnaud为了推断语法,一些看待数据分布的模型的“方法”感到“困惑”。他说,“我认为标准治疗方法存在一个问题,即只是从检查字符串中得出短语结构或一致结构。”Norbert Hornstein说,“我觉得这里的刺激贫困被认为是一个问题,我感到很有趣。”这次会议认为这是一个需要解决的问题,并且“在我这个世界上,它是一个非常有效的工具,而不是给定的问题,我们知道它存在。”他说计算主义者“似乎认为我们是人谁生成短语结构语法。 ......坦率地说,这些是外围问题。“他指出,许多语法学家对语言能力的初始状态的性质感兴趣,并建议询问当前的统计技术如何研究这个问题可能是有用的。威廉·萨卡斯重复了他的“关于如何将统计模型缩小到可行地体现在孩子身上的讨论”的要求.Anna Maria Di Sciullo说,“概率模型被认为是语言习得的模型。如果我们看一下人类拥有和获得语言,无论是文字,句子还是文本,人类往往会对不同种类的结构产生不同的行为。“此外,儿童不会立即获得语言,而是通过一套错误。她似乎怀疑基于概率的模型能够解释人类语言习得中发现的各种细微模式。问答时期包括小组成员和会议参与者之间的一些精力充沛的交流,包括Josh Tenenbaum,Lila Gleitman,Chris Manning ,Amy Perfors和Partha Niyogi。
课程简介: It was uncertain by the end of this panel if linguists and computational scientists could find meaningful common ground. As conference organizer Michael Coen initially stated, “The issues we’re discussing are as religious to people as the Red Sox.” The two disciplines view their shared territory in distinctive ways, leading, in this panel and subsequent discussion, to some friction. Moderator Charles Yang sums up the preceding talks, describing how presenters explored such issues as whether statistical models could adequately capture psychological and linguistic complexity, and whether the learning models fit the developmental data. He cites continued conundrums, such as “How does a child do something that is so apparently in contradiction with what’s in the data,” which he would like to see addressed in discussions of statistical learning of syntax. Robert Friedin comments, “What I noticed in the presentations of modelers was that syntactic representations put forward were not syntactic representations that I would accept. There is an assumption in linguistics that language has a particular …syntactic structure and not another. … If you have a theory of grammar that gives you the right set of syntactic representations, you might want to say, let’s take that and now let’s see what else do we need to add to explain other things on the periphery.” Jean-Roger Vergnaud is “puzzled by the approach” of some models that look at the distribution of data for the purpose of inferring grammar. He says, “I think there is a problem with standard treatments that purport to derive phrase structure or consistent structure just from examining strings.” Norbert Hornstein says, “I was amused that poverty of stimulus here was considered a problem.” Many people in this conference looked at it as a thing to solve, and “in my part of the world, it’s an extremely effective tool, not a problem -- a given, we know it exists.” He said that computationalists “seem to think we’re people who generate phrase structure grammars. …Frankly these are peripheral issues.” He notes that many syntacticians are interested in the nature of the initial state of the language faculty, and suggests it might be useful to ask how current statistical techniques could study this question. William Sakas repeats his request for “discussion about how statistical models might be scaled down to feasibly be embodied in a child.” Anna Maria Di Sciullo says, “Probabilistic models have been said to be the models of language acquisition. If we look at human possession and acquisition of language, whether words, sentences or text, a human tends to have different behavior with respect to different sorts of structures.” Also, children don’t acquire language instantaneously, and instead go through a set of errors. She seems dubious that a model based on probability would be able to account for the kinds of nuanced patterns found in human language acquisition. The question and answer period includes some energetic exchanges among panelists and conference participants, including Josh Tenenbaum, Lila Gleitman, Chris Manning, Amy Perfors, and Partha Niyogi.
