The registrar's own records: 165 grades over 2 terms, Fall 2021 to Fall 2025. Every instructor is pooled here.

What is inside that record

No summer session is in that record.

The table below splits them, and term averages across those 2 terms ran 3.65 to 3.92.

Historical grades for GU, QUANQUAN, across recorded terms. The course summary above includes all professors.

  • B+ 16 · 9.7%
  • B 8 · 4.8%
  • B- 7 · 4.2%
  • C+ 1 · 0.6%

Percentages are of the 165 letter grades. Grey bars are non-letter outcomes.

How the non-letter outcomes are counted

They are excluded from the GPA entirely rather than scored, because counting a P as a 4.0 would be a fabrication.

Why Predicted is not the Raw average

“Predicted” is shrunk toward the course average, which is itself shrunk toward the department, so an instructor with a handful of students sits near the course mean rather than topping the list.

Workload and assignments

Work types reported in BruinWalk reviews of this course, across recorded instructors and terms. They may differ from this term's syllabus.

dibs has not read this course’s reviews, so it cannot say what kind of work it sets. That is dibs not having looked. It is not a course without papers or exams, and the reviews linked below are the answer until dibs catches up.

In Falls

Ran in 2 of the last 5 Falls, so it turns up in Fall sometimes rather than dependably. dibs has no record of it in any quarter since Fall 2022.

From the terms dibs holds, which start in Fall 2021 and exclude summer. A department can run a course in a quarter it never has before.

From the registrar's catalog

Lecture, four hours; discussion, two hours; outside study, six hours. Recommended requisite: course 180. Problems of identifying patterns in data. Machine learning allows computers to learn potentially complex patterns from data and to make decisions based on these patterns. Introduction to fundamentals of this discipline to provide both conceptual grounding and practical experience with several learning algorithms. Techniques and examples used in areas such as healthcare, financial systems, commerce, and social networking. Letter grading.

Sections in Fall 2026

You enroll in the discussion, not the lecture, so a discussion's status is the one that decides whether you get in. A lecture can read open while every discussion under it is full.

Seat counts as of : the oldest of these 6 readings. Seat readings are snapshots, not live availability. Their timestamps show when dibs last checked.

Final enrollment, averaged across each term's sections: between 76 and 89 a term over 2 terms, summer excluded, most recently 89 in Fall 2022. That is the shape across years, not this term, which is above.

Seats over time in Fall 2026

How each lecture has filled since dibs first saw it. This course runs 2 lectures; the legend under the chart picks one.

A dot is a reading where something moved: the seat count, the status, or the waitlist.

What a flat run means, and where a line starts

Flat between dots means it did not drift, it held and then jumped, and a line starts when dibs first saw that lecture rather than reaching back before it existed. A lecture that has never moved draws a flat line across the whole window, and one with two or three readings draws a line joining them, which is too few to read a trend from.

Lec 1 · Gu, Q. · 120 of 120 enrolled

Nothing read since 24 Aug, about 1 month ago. Over the 7 days before that, same seat count, but the waitlist went 26 of 30 to 29 of 30.

120 of 120 · no seats left in its discussions

173 hours plotted. dibs took 7 readings inside them and kept no hourly record of the hours between.120 of 120 enrolled at the newest reading, about 1 month ago, and no seats left in its discussions. Seats from 17 Aug 15:07 to 24 Aug 19:40, 120 to 120. The line is flat across the whole window: recorded enrollment counts match. Changes between reads may be missed. dibs holds no hourly read record inside this window at all, so nothing drawn here says the count was checked between the readings. No hour here has a read either way, because dibs holds no read log for this section at all. Where the drawing is faint or broken, that never means the readings are doubtful. It means the stretch between them is unaccounted for.

How readings and alerts work

A reading and an hourly record are different things, and most charts here hold more of the second missing than present. dibs has taken readings of a section since long before it began keeping an hour-by-hour log of when it looked, so the empty stretches are dibs saying it was not keeping that log yet, not that it looked and found nothing. That is the age of the record and not a fault.

Seat counts show the last successful read, not live availability. Refreshes can be delayed by request limits or upstream interruptions. Watched sections receive priority, but an hourly update for every section is not guaranteed.

The registrar can change a seat count between our checks. Alerts depend on dibs detecting an opening and completing delivery; a quiet watch does not prove that no seat opened. Check the registrar before enrolling.
