1
UCR CS 260 SEMINAR IN COMPUTER SCIENCE 
  • 940 a.m. - 1100 a.m.
  • CHUNG 139
  • Winston Chung Hall (CHUNG)
  • Eamonn KeoghComputer Science Engineering
    Departmenteamonn(AT)cs.ucr.edu

2
Format of the Class
  • Very informal
  • We will take turns to present and discuss papers
  • You will be graded on your presentation, and on
    your participation

3
Presenting a paper
  • You can request the original slides from the
    author (for a conference paper).
  • Write a very polite email to first author, but CC
    all authors.
  • You need to do this well in advance.
  • You need to augment the slides, and make it clear
    what are your words/analysis
  • Plan to speak for 25 min (not counting
    questions/discussion)

4
Prepend anything we need to know before you start
discussing the paper. At a minimum, where/when
the paper was published and its impact Us a
different font color to make it clear these are
your words
Append a discussion of the paper Us a different
font color to make it clear these are your words
5
Your discussion of the paper
  • Is the paper
  • Original? (including original compared to
    authors previous work)
  • Well written?
  • Well motivated?
  • Well illustrated?
  • Are the experiments
  • Forceful
  • Fair to rival methods
  • Reproducible
  • Does the algorithm require many parameters, if so
  • Is it explained how to set them?
  • Are we shown how sensitive the results are to
    them?

6
Your discussion of the paper
  • What are the limitations of the work?
  • Are they clearly stated?
  • What are the assumptions of the work?
  • Are they clearly stated?
  • Is there a good literature review? If not, what
    is missing?
  • Do you think a simpler method might have worked
    as well as the proposed method?

7
Your discussion of the paper
  • Did the paper garner interest?
  • Consider Eamonn J. Keogh, Jessica Lin, Ada
    Wai-Chee Fu HOT SAX Efficiently Finding the
    Most Unusual Time Series Subsequence. ICDM 2005
    226-233

It has 276 citations It was expanded into a
journal paper (which has 54 citations)
8
Your discussion of the paper
  • Did the paper garner interest?

It is the most cited paper, of that conference in
that year
9
You need to understand the paper
  • I know you did not write the paper, and you are
    not responsible for the content.
  • However you cannot simply show someone else
    slides and shrug you shoulders if asked
    questions.
  • You should try to anticipate any questions that
    an audience member might ask, and research an
    answer.
  • So, to present a paper, you might have to read 3
    or 5 other papers. http//videolectures.net/

10
You need to understand the paper
  • Hint many papers have videos of their
    presentation online. Often you can hear the
    audience questions

Lier aide d'interprétation II
Sur cette figure, la couleur des flèches à
l'intérieur de la liaison de poisson pour les
couleurs des flèches de la série chronologique.
Cela nous dit exactement comment nous allons
partir d'une forme à une série de temps
Figure 4 I) A l'intuition visuelle de la
conversion d'une forme bidimensionnelle à une
"série temporelle" unidimensionnelle. Ii) deux
formes qui sont similaires à l espace forme sera
également similaire dans la forme de séries
chronologiques. III) Ici, nouscomparer un poisson
(Priacanthus arenatus) à partir d'un Cubain de 40
ans manuscrit à un poisson connexe (Priacanthus
de hamrur) à partir d'un manuscrit publié en 1899.
Minimalisme aide Dans ce cas, les numéros sur
l'axe X ne veut rien dire, ils sont supprimés
12
Linking helps interpretability II
In this figure, the color of the arrows inside
the fish link to the colors of the arrows on the
time series.
This tells us exactly how we go from a shape to a
time series.
Note that there are other links, for example in
II, you can tell which fish is which based on
color or link thickness linking.
Minimalism helps In this case, numbers on the
X-axis do not mean anything, so they are deleted.
13
Where to find Papers?
  • I have given some suggestions on the next page.
  • You can also find papers by..
  • Looking through the proceeding of major
    conferences, SIGKDD, ICDM, SDM, ICDE, NIPS, VLDB,
    SIGMOD, ICML
  • Topic driven (outside of data mining) If you are
    interested in astronomy or insect (or anything)
    there is probably a data mining paper on it.
  • Data mining Topic driven I would like to learn
    about DM for/with social networks, active
    learning, anytime algorithms, privacy
    preservation, mobile devices, bloom filters,
    personalization, deep learning, the reasonable
    effectiveness of data, fraud detection,
    anti-terrorism, advertising 
  • Person Driven You know of an interesting
    researcher
  • I want to see interesting papers, sometimes bad
    papers can be interesting -)
  • Please run your idea by me first
