2 . Welcome

This course explores the concepts and algorithms (算法) at the foundation of modern artificial intelligence, diving into the ideas that give rise to technologies like game-playing engines, handwriting recognition, and machine translation. Through hands-on projects, students gain exposure to the theory behind graph search algorithms, classification, and other topics in artificial intelligence and machine learning as they incorporate them into their own Python programs. By course’s end, students emerge with experience in libraries for machine learning as well as knowledge of artificial intelligence principles that enable them to design intelligent systems of their own.

Requirement

CS50x or at least one year of experience with Python.

3 . AP at a Glance

The Advanced Placement ® Program (AP) enables willing and academically-prepared students to pursue college-level studies while they are still in high school. The program develops college-level courses that high schools can choose to offer and corresponding AP exams that are administered once a year.

·AP courses are available in seven subject categories.

·Each AP course is modeled on a comparable introductory college course in the subject.

·Each course comes to an end in a standardized college-level assessment or an AP exam.

·AP exams are given in May each year at testing locations all over the world.

·Schools must be authorized by the AP Course Audit to offer approved AP courses and use the “AP” designation (名称).

Taking AP courses and exams can help students:

·Stand out on college applications. AP courses on a student’s transcript (学生成绩报告单) show that they’ve challenged themselves with the strictest courses available to them. And success on an AP exam shows that they’re ready for college-level coursework.

·Earn college credits and skip introductory courses in college. Most four-year colleges and universities in the United States, as well as many institutions in more than 100 other countries, grant students’ credit, placement, or both for qualifying AP exam scores.
