Summary

1 / 6

Past student reviews · John Gillett

The workload was described as manageable compared to programming courses, though exam problems required careful review and some critical thinking.

What you’ll be able to do

  • Understand the different subfields of machine learning, such as supervised and unsupervised learning and being familiar with essential algorithms from each subfield.

  • Identify whether machine learning is appropriate for solving a given problem task and which class of algorithms is best suited for real-world problem solving.

  • Use statistical learning theory to combine multiple machine learning models via ensemble methods.

  • Apply best-practices for statistical model evaluation, model selection and algorithm comparisons including suitable statistical hypothesis tests.

  • Use contemporary programming languages and machine learning libraries for implementing machine learning algorithms such that they can be readily applied for practical problem solving.

  • Connect concepts from probability theory with supervised learning by implementing models based on Bayes' theorem.

About this estimate

The course’s semester-average GPA, not an individual student’s grade. The center uses 5 same-season terms, weighted toward recent results.

The range uses the finite-sample 80th-percentile rank of absolute errors from earlier same-season forecasts. Each forecast uses only records from earlier terms. At least four forecasts are required; bounds are rounded outward and limited to 0–4. This is an empirical estimate: changing instructors or grading policies can reduce its coverage.

About this comparison

1280 courses over the same term, each with at least 30 recorded letter grades. Cross-listed courses count once. GPA is not a measure of difficulty or teaching quality. The typical course is the median by recorded grade count; tied values are not counted as lower. Grade counts describe course scale, not unique students or typical section size.

Descriptions compare GPA with this group’s average: at least 0.20 higher or lower; otherwise close to average. Section size uses median recorded enrollment: small up to 30, mid-sized 31–99, large 100+. Lectures and discussion/lab sections are described separately.
