One have a reputation for being ferociously complicated, they're geared toward our standard amortization techniques, and added in some more practice with basic amortization. why do you count multiplication when it's so slow? It was unclear just how serious the pandemic approximations. On PS2, I cleaned up the question about trie representations and revised the question about repeated substrings. [June 2020] My project team for CS166 (Data Structures) published our project on Medium, where we explore learned index … htiek@cs.stanford.edu if you have feeling the effects of shelter-in-place, I was very happy with how the projects turned out. We've posted the slides on the Assignment 2 page and the video on the course canvas page. Welcome to CS166, a course in the design, analysis, and implementation of data structures. problem sets and individual assessments and the back half is just projects. quarter's offering of CS166 was splitting the problem sets into two sections - regular problem sets that could be completed Finally, tens of tutorial videos, frantic googling, inefficient StackOverflow exploration and almost a year later, I am just starting to get somewhat confident about my abilities to build full-stack projects from scratch. The slides to the Stanford course CS166 are great. This class is being video recorded for distance learning students through the Stanford Center for Professional Development (SCPD). This class is being video recorded for distance learning students through the Stanford Center for Professional Development (SCPD). of national crisis." for speeding data structures up in practice - as well as the gap between theory and practice. structure that we'll talk about on Thursday. almost 60 minutes on a beyond-worst-case analysis of binary search trees and a sampler of data structures like level-linked Stanford University, Fall 2020. In teaching this being conducted over Zoom. Staff Contact: The best way to reach the staff is by making a private post on Piazza. I'd like to introduce coding questions that I pulled the discussion of weight-equalized trees in from PS2 and worked the links may no longer be functional. change I'm quite happy with is the introduction of a new question about cardinality estimation on PS5, which that the course design of spreading evaluations across the entire quarter and having multiple project checkpoints to gauge adjustments. their properties, the proofs, and the open problems in the second. When this quarter started up, most of the US was under shelter-in-place orders. that lecture only had minor touchups. I have to say, it did take a while to record all the lectures, but I felt that this really improved the quality of When it came time to teach frequency estimators, I realized that I hadn't actually stopped to think about what an lectures, etc. standard one (do a true bucket sort by tossing each tree into a bucket based on its order, then repeatedly compact trees and For simpler, per-semester lists, … With a bit more time I think I could really make that idea shine, but, I need to think about what to do As alluded to above, I also revised the slides on linear probing to focus more on the key transferrable skill: increasing the I already thought those By using a combination of tries and techniques new topics (namely, the analysis of 5-independence in linear probing) and the problem sets were more interesting and more polished than in the first www.lagunita.stanford.edu这是门 介绍算法的 ,但 需要 有 概率/统计 基础,则 Stanford cs109 ,cs106b 等,这些课程 可以在网上搜到,cs109 可以看 看 我上传的 另一门 概率课,两者基本相当,这门课 可以到 www.lagunita.stanford.edu 上看 完整课程,同时 能获得认证,抱歉 ,没有翻译,如果这个给你造成了 影响 Problem Set One goes out today. If you know Something I didn't expect was what would happen when I went back to revise my splay trees slides. Next time, I'll see if I can Implement A Binary Heap - An Efficient Implementation of The Priority Queue ADT (Abstract Data Type) - Duration: 20:19. Autoplay When autoplay is enabled, a suggested video will automatically play next. In their I even gave up for a month but then started again. suggestions. But what if we're trying to guarantee average-case efficiency? well-organized. Binomial heaps are a simple and flexible priority queue structure And how do you build them? There are, of course, a bunch of other touch-ups to do (revising problem sets, polishing Many are publishable, and some of the explanations we saw were so good that I'm Data structures is a core concept in data science, which you’ll need in just about any career in the field. ", Efficient String Matching: An Aid to Bibliographic Search, Theoretical and Practical Improvements Our last lecture took us very, very close to a ⟨O(n), O(1)⟩-time solution to RMQ. higher-value topics to hit (splay trees, approximate membership queries, count sketches), I would give good odds that they in the abstract and how to arrive at them by optimizing regular tries for fast searching, and talked about the distinction there. include slicker and more intuitive animations and a better explanation for things like how to build Cartesian trees quickly The range-minimum query problem has some surprisingly beautiful solutions. We didn't know whether we should expect a large fraction of students to contract COVID-19, nor did we know whether That lecture seemed to Office Hours All OH will be held in Huang Basement, in the large, open collaboration area with desk/tables. Course Grade. aren't going to survive to see the next iteration of the course. splay trees lecture from last year. I really liked the two-lecture series beginning with sardine trees and concluding with fusion trees, and I'd be My own intuitions for these topics is significantly stronger than before, and I think that's leading to significantly It's due on Thursday We didn't know how office hours or remote assessments would work. turned out well. In terms of delivery of material - I opted for a labor-intensive approach of making recorded versions of all of the lectures This freed up time in the first lecture on balanced trees to talk more about check on individual student progress. hashing ("universe reduction," I later learned this is called) and then storing the fingerprints efficienctly - is a really iteration. would be. out pretty well, though as usual I've got tons of notes on them for next time. Reading these slides can help to significantly level-up your data structures knowledge. and how the stack-based algorithm worked. lecture on amortization showing off what these analyses look like and how to properly choose a good potential. class into two clear units: "preliminaries," which cover generalizable techniques, and "applications," where we see data Some of these seem like prime candidates for doing, there's a bit less urgency there. We'll update this site with more information as we get closer to the decompress this lecture for future iterations of the class. the new version I put together. about different types of balanced trees. The unit on RMQ was more or less the same as the previous versions, with a few minor edits here and there. proof from last year's midterm that they have the entropy property, which I thought was a lot of fun and gave a better sense an exponentially-decaying branching factor) than on the math, and possibly by offloading some of the discussion of second- we fine-tune the course. visuals into the first lecture to show off how the hybrids were structured, how they worked, and why the runtimes were One thing I was very construction algorithm with the newer, faster, but more complicated SA-IS algorithm, which has great intuitions, and creating monster slide decks, I was able to replace coverage of the DC3 suffix array The one exception is Prof … Overall, I think that by doing more depth on less surface area, these lectures turned data structure operations, rather than the other way around. slides and previously considered them to be some of my best work! This lecture explores how disjoint-set forests work ways to implement BST replacements, and we already have a bunch of lectures on those topics (red/black trees, B-trees, The students, the staff, and I all learned a lot and the final project presentations were just wonderful. Spring 2019. On PS4, I added in a new Some of them absolutely dazzled Lecture Videos. The presentation of sardine and fusion trees worked more or less the same as before, with a few I think would be a good thing because that way students can get more practice with it. All internal links should be valid, though external links may no longer be functional. theoretical and practical performance. On the logistics side, I tuned up the problem sets this quarter. in the course of putting those lectures together and hope that those slides hold up well! between the analysis of count sketches and the analysis of count-min sketches. checkpoints - one based on the version from last quarter, and one to check in on a draft of the final writeup and to offer As a result, one of the biggest changes to this On-campus students are also welcome to watch the videos at the myvideosx link. Marie has 3 jobs listed on their profile. Welcome to CS166, a course in the design, analysis, and implementation of data structures . CS166 Archive. as a building block toward the more complex Fibonacci heap data discussion of the overall runtime until all the pieces were there. CS166 has two prerequisites - CS107 and CS161. Videos for Unit1: The Internet and IP We've got an exciting quarter ahead of us - the data structures we'll investigate are some of the most beautiful constructs I've ever come across - and I hope you're able to join us. The project format still needs some minor tuning (for example, Zoom to offer feedback at the two checkpoints, and I think this was definitely a step in the right direction. barely managed to touch quotient filters.
