Which is Research?
IPHONE VISTA SIDEBAR
What is Research?
Research (in Computer Science)• Novel concrete or abstract
CS-related artifact?• Argument made why
significant and interesting– Paper– Talk
• It is the argument that must be new, not necessarily the artifact– New artifact does help
increase significance• Research done in the
process of arguing it!• Most things we learn
should apply to any engineering field– Maybe not science

Collaboration Toolkit
GPU-based Algorithm

Asynchronous- Logic Chip
Measurement of Network Traffic

Measurement
iPhone as Research
• Research implies a an analysis of previous work (survey/related work discussion)
• Will focus on surveys– Hardest part of
paper/talk
Paper/Talk• Paper: document
created• Talk
– Slides and/or Delivery
– Some talks do not have slides!
– Talk = Recording
Crafting• In the small
– Grammar, PPT Animations– Style, PPT Color Choices– Analogous to defining an object
• In the large– Composition of prose and slide
items– Analogous to design principles
and patterns
• Assume proficiency in design in the small
The passive voice should not be used!
Use light text on dark background !
Have an abstract, introduction, body , conclusions and future work
Have a title, outline, body, conclusions , and future work
Software Design Pattern
• Arguably good composition techniques
• Situational• Examples!• Practice
Write Metho
d
Notification
Read Metho
d
Model
Controller(Performs Input)
View(Performs Output)
Design pattern found in many applications
State of the art in Software engineering
• Arguably good composition techniques
• Situational• Examples!• Practice

State of the art in Papers/Talks
• Arguably good composition techniques
• Situational• Examples!• Practice
State of the art in Papers/Talks
• Arguably good composition techniques
• Situational• Examples!• Practice
No one seems to have addressed !
Such Principles/Patterns Exist
Each student seems to make the same kinds of mistakes!Have compiled mistakes made by students of last class
Even if you disagree with class patterns/principles
• Practice• Practice• Practice• Most of talk practice done
offline using recordings• Office 2007• LiveMeeting
• Good also for audience– Viewing a good talk can
inspire and teach– Easier to see others’ mistakes
Why Integration of Talk/Paper• Research done in the process
of arguing it!• At an abstract level,
argument in talk and paper not that different
• Abstract argument is most important
• Concrete recommendations may also be very similar
Have an abstract, introduction, body, conclusions and future work
Have a title, outline, body, conclusions , and future work
Difference?• Paper usually has more details
– More true for journal paper– Which details to omit an important
issue in giving talks• Talk an advertisement for paper• Talk is less formal
• Can afford to make grammar mistakes
• Easy to lose concentration in a talk– Can re-read paper– Papers usually do not have as good
a flow• In this course, paper is almost a talk
transcript
Which comes first: Paper?• Usually conference
paper before talk• Get the details before
abstracting (bottom-up approach)
• Can answer detailed questions in talk
Which comes first: Talk?• Interview talk before thesis written• Get the abstraction/outline first
– Top-down approach– Paper is an expanded version of
the talk• Easier to get reviewer of talk than
paper– Quality of main argument better
evaluated• When integrating papers, details
already there, so no advantage in going to paper first
• Can use figures of talk in paper• Maybe easier to go from informal
(conversational) to formal.– Often people end up reading
paper in talk.
Which is harder: Paper?• More details
– More things to go wrong
– Wrong proofs common in papers
Which is harder: Talk?• Abstraction is harder
– “I am sorry I did not have time for a shorter letter”
– “Length is used to compensate for lack of depth”
• Once talk is made, paper is easy• Will spend much more time on
talks– More of an in-class activity
Series of Talk-Paper Pairs
• First give a talk on some topic.
• Then write a paper that has the same content and flow (it may even be a transcript of the talk)

Lots of work!
Student Level
• 2nd year student– Ph.D. qualifying talk and paper
• 1st year RA– Allows you to abstract out and understand what you are doing
• 1st year TA– Allows you to explore an area
• Student writing thesis/proposal– Hardest part of your career
• Master’s student– Integrative comprehensive paper
Previous Skills Matter?
• No matter how good you are, much scope for improvement– How many talks do you listen to with rapt attention and
understand?– How many papers have you enjoyed reading?
• Students expected to start with varying skills and background
• Graded mostly on how much improvement you show
