Introduction to Java
Why Java? Java is popular There are reportedly 9 million Java developers in the world (in 2014), 930 million Java Runtime Environment downloads each year and 3 billion mobile phones run Java. Java is modern A high level programming language that is based on the object-oriented paradigm. Java is convenient Automatic memory management Java is portable: Java programs run similarly on any hardware/OS platforms. Java is powerful The Java standard library offers a wealth of tools for different functions.

托福听力slides 1.内容主旨题

Listen to a conversation between a student and his sociology professor.P: Well, I’m glad you redid your outline. I fed a few comments, but nothing you have to act on. It’s in good enough shape for you to start writing your paper.S: Thanks! At first I was afraid all that prep work would be a waste of time.P: Well, especially with a challenging topic like yours: factors leading to the emergence of sociology as an academic discipline. There’s just so much history to consider; you could get lost without a solid outline. So did you have a question? S: Yeah, it’s about…you mentioned needing volunteers for a research study?P: Yep, it’s not my study. It’s my colleague’s in the marketing department. She needs people to watch various new TV programs that haven’t been broadcast yet, then indicate on a survey whether they liked it, why, if they’d watch another episode. It’d be kind of fun plus participants get a $50 gift certificate.The topic of the research paper Some current research projects in sociologysociologyparticipation research projectD.The man’s possible participation in a research project例题 2. What is the lecture mainly about?A. Different kinds of color vision in sea animals.B. Differences in appearance between various species of octopus.C. Ways that octopuses attract their prey.D. Ways that octopuses protect themselves from predators.Narrator：Listen to part of a lecture in a biology class. Professor：Ok, now I want to talk about an animal that has a fascinating set of defense mechanisms. And that’s the octopus, one of the unusual creatures that live in the sea. The octopus is prey to many species, including humans, so how does it escape its predators?例题 2. What is the lecture mainly about?A. Different kinds of color vision in sea animals.B.

Texts
Required:
• “Introduction to Machine Learning” • Ethem Alpaydin, MIT Press, 2004
Various other good, but optional, texts:
• “Pattern Classification”, Duda, Hart, Stork, Wiley, 2001 • “Elements of Statistical Learning”, Hastie, Tibshirani, Fredman, 2001 • “Pattern Recognition and Machine Learning”, C.M. Bishop, Springer, 2007.

f (· )
ˆ = f ( x) ≈ y y
This is called training or learning. Two major types of learning:
• • Unsupervised: only X is known, usually referred to as clustering. Supervised : both X and target value Y are known during training, only X is known at test time. Usually referred to as classification or regression.
