This document contains a vocabulary quiz with 3 sections - a biography, animals, and phobias. In the biography section, learners are to choose the correct word to complete sentences about a woman's life from childhood to death. The animals section tests knowledge of different animal names. The phobias section focuses on vocabulary related to fears and phobias.
The document is a vocabulary test with 20 multiple choice questions about prepositions. The questions test knowledge of common prepositions like "across", "through", "into", "up", "down", "onto", "out of", "past", "towards", "forward", "up", "down", "on", "over", "out", "up", "after", "for", "like", "both", "as", and "similar" in the context of different sentences. The test-taker must choose the correct preposition from the options given to complete each sentence.
The document is a vocabulary test with fill-in-the-blank questions to complete verb phrases and sentences. It tests knowledge of common English verbs and verb tenses, including past participles. There are three sections - the first asks to complete phrases using verbs like "belong to" and "get on". The second focuses on verbs like "said" used in sentences. The third uses past participles to complete sentences such as "had written" and "had flown".
The document provides examples of grammar exercises involving the present simple, present continuous, past simple, past continuous, and present perfect verb tenses. The exercises include completing sentences with the correct verbs, writing questions, and choosing the appropriate verb form for given sentences. The document tests a learner's understanding of basic English verb conjugations and usage.
This document summarizes the results of testing three chatbots: Eliza, Alice, and Captain Kirk. It finds that Eliza only responds to keywords with questions, while Alice answers most questions properly and interacts by asking follow-ups. Captain Kirk's answers are sometimes the same as Alice's, but sometimes don't make sense. Overall, Alice is deemed the most intelligent and convincing as a human.
This document provides a summary of a 30-minute presentation on feature selection in Python. The presentation covered several common feature selection techniques in Python like LASSO, random forests, and PCA. Code examples were provided to demonstrate how to perform feature selection on the Iris dataset using these techniques in scikit-learn. Dimensionality reduction with PCA and word embeddings with Gensim were also briefly discussed. The presentation aimed to provide practical code examples to do feature selection without explanations of underlying mathematics or theory.

25. 人工智能标记语言 AIML ALICE 采用 AIML(Artificial Intelligence Markup Language) 作为它的知识描述语言 AIML 是利用 XML 标准定义的一种服务于人工智能领域需要的特定语言 , 设计 AIML 的最初意图就是为了能够用最简单的方式来创建人工智能聊天机器人
26. AIML 语法构成要素 The most important units of AIML are: <aiml>: the tag that begins and ends an AIML document <category>: the tag that marks a "unit of knowledge" in an Alicebot's knowledge base <pattern>: used to contain a simple pattern that matches what a user may say or type to an bot <template>: contains the response to a user input
