Discussion Schedule
Please note the important information below the table. The set of ASEs assisting with a given discussion (if any) is given by the bulleted list.

Note: Monday and Wednesday discussion sections cover different material, and you are very strongly encouraged to go to a discussion both days. Scroll horizontally to view entire table, and see below for critical information on how to read the table.
To account for different learning styles, there will be 3 different styles of discussion sections.
 The first set of sections are “Group Sections" (blue) . These discussion sections will be staffed with a TA and many ASEs, and students will be given a chance to work with each other in breakout rooms.
 The second type of sections are "Individual Worktime" (green) , which are more oriented toward individual work and are intended for students who prefer working solo and not in groups. Here, the TA will give you time to work on the problem on your own and then discuss the answer.
 The last type of section (similar to the second type) is "Lecture Style" (purple) . There may be slightly less time for individual work on the problems in the Lecture Style sessions, but TAs will be there to answer questions in all sessions.
Furthermore note the following; despite the bold labels in some sections, all sections are open to all. However, to facilitate similar groups of students getting to know each other, we have designated sections according to categories. Freshman section or Freshman/Sophomore sections are intended for these specific years of students. Transfer sections are intended for Transfer students. The Linear Algebra experience section is intended for upper division students who might have some prior linear algebra experience. Again, all sections are open to all.

Textbook: Condensed Note Content Summaries and Practice Problem Solutions
This book consists of condensed sets of notes that summarize the important material from the course notes, as well as detailed solutions for the online Practice Problems! Here's the entire book and the Table of Contents. Individual chapters of the book (notes and solutions by practice set) can be found here (the links aren't perfect, you may need to scroll a tiny bit down for some chapters). A couple brief comments on using this resource:
 I recommend skimming the Introductory Chapter and the Conventions Chapter. These will provide some useful tips to keep in mind.
 Each chapter has a Relevant Information section and a Problems section. The first contains a (generally complete) summary of the corresponding content from the notes. The second contains the detailed solutions mentioned above.
 This is a new resource, and may well have errors or areas to improve in; if you spot something wrong and would like to mention it, or have feedback of any kind, please submit a feedback ticket.

Please add berkeley.edu to the end of all emails!Instructor
I'm a professor in Electrical Engineering and Computer Sciences, and I work on research on Computational Microscopy, in which we design imaging systems that use physics/optics hardware and computational software together to do things that neither could do alone. Your cell phone camera probably has a lot of great examples of computational imaging, like portrait mode, HDR, and image bursts, and we'll learn a bit about imaging in this course! I look forward to working with you all this spring, even if only via Zoom.

I'm a thirdyear EECS major currently conducting research in power electronics. My favorite part of 16A is the circuits module: I find the creative aspect of circuit design to be quite rewarding, and the handson lab work is super fun. Outside of academics, I love outdoor adventures (particularly aquatic ones), classical music, and cooking.

Hi! My name is Anika. I am a 3rd year studying Industrial Engineering and Operations Research (IEOR for short) which is all about optimization and efficiency (i.e. making the world as lazy as I am)! This is my fifth semester on course staff for EECS 16A. I love this class because it helps bring fundamental concepts to life through an application focus. Outside of academics, I love to spend time with friends and watch netflix (always looking for good recommendations!) I am also a dancer and enjoy karaokeing disney songs. I look forward to this semester and I hope to help make this class a great experience for each and every one of you. Welcome to EECS 16A!

Hey there! I'm a second year EECS major currently involved in research in computational imaging, and this is my fourth semester on course staff. In my free time I love cooking, knitting, and walking around Berkeley. I loved taking 16A because it teaches how to use the concepts of linear algebra and circuit analysis as tools to apply to real problems, and I hope you enjoy the course as much as I did! I'm excited to get to know you this semester :)

Hi! I'm Raghav, a junior in the EECS major. I am really interested in Computer Architecture, Machine Learning, and Quantum Computing (so far :). 16A is one of the best classes I've taken at Berkeley so far because of the unique perspective it gives one on solving real world problems with the simplicity of linear algebra. I'm very passionate about aviation, technology, soccer and F1. I love traveling, hiking and endurance running and cycling. Oh and I thoroughly enjoy talking to people, so feel free to hit me up!

Hello! I’m a sophomore studying Computer Science as an excuse to start the robot uprising. Currently, I’m researching how to teach robots to walk upright and push blocks on a table with machine learning (read: linear algebra). When I get frustrated with their progress, I watch Korean movies, write about philosophy, appreciate wordplay in books and puzzles, and reminisce about how cool least squares is.

I am a junior, majoring in Physics, Computer Science, and Applied Mathematics. My primary technical interests and areas of research activity are in Condensed Matter Physics and Quantum Information theory. I am particularly interested in the application of Quantum algorithms to Optimization and Machine learning problems. Outside academia, I participate in British parliamentary debate with the Debate Society of Berkeley. My favourite things to do in Berkeley in my spare time are to go on long bike rides and to hike the fire trails. I think that EECS16A is a uniquely foundational class, as it teaches immensely useful fundamental ideas in linear systems theory that are used virtually everywhere in the physical sciences and in engineering, at every level of complexity. I particularly enjoyed that the class exemplifies how a small but powerful set of mathematical tools and hardware abstractions can be used to design notably sophisticated systems.

About
EECS 16AB Course Coverage
EECS16AB was specially designed to ramp students up to prepare for courses in machine learning and design and are important classes to set the stage for the rest of your time in the department. A rough breakdown of the content in the classes is as follows:
16A:
Module 1: Introduction to systems and linear algebra
Module 2: Introduction to design and circuit analysis
Module 3: Introduction to machine learning
16B:
Module 1: Differential equations and advanced circuit design
Module 2: Introduction to robotics and control
Module 3: Introduction to unsupervised machine learning and classification
FAQ
Q1: Should I take EECS16A my first semester at Cal?
A1: If you have taken an AP calculus class, then the answer is yes! EECS16A has no prerequisites other than calculus and is designed with freshmen and incoming transfer students in mind. It is designed to be taken alongside 61A. Furthermore, we reserve seats for freshmen and incoming transfer students in the class, so you are essentially guaranteed a spot in the class your first year. It will be harder to get into the class as an upperclassman.
Q2: Should I take EECS 16A and EECS 16B before or after CS 70?
A2: EECS16A and 16B were specifically designed to help ease the transition to CS70 for incoming students. These classes provide an introduction to proofs and the kind of mathematical thinking that is very useful in a class like CS70. We recommend you take 16AB before taking CS70, this should help you have an easier time in CS 70.
Q3: Should I take MATH 54 before taking EECS16A?
A3: EECS 16A is designed to be taken without any prerequisites, so there is no need to take MATH 54 before EECS 16A. EECS 16AB teaches linear algebra with the intent of preparing you for courses like EECS 127 (Optimization) and EECS 189 (Machine Learning) and provides engineering and machine learning examples and applications for linear algebra. EECS 16AB also uses Jupyter notebooks and python so you can better connect linear algebra and computation.
