Your Prezies

Deliverable 1

• during the whole seminar, in particular the discussion of

fellow students’ presentations you

• are present
• participate actively


Make sure you’ve signed the attendance sheet During your presentations, we will all give feedback 
 (directly verbally & via those Feedback Notes)

Deliverable 2 - new

• attend all presentations of the Research Symposium
• we will identify ~40 new presentations from video lectures

– email me your suggestions, I will add them to our list – suggest those that you’d like to see

• you

– pick 5 presentations from these ~40 – for each of these, you

• give a 2-3 sentence summary of its contents and
• write a critique: what was good, what could have been better
• taking into account all 3 aspects of a presentation

– storyline – slides – presenter

• submit all your summaries and critiques via easychair

Deliverable 2 - new

• attend all presentations of the Research Symposium
• we will identify 30-50 new presentations from video lectures

– email me your suggestions, I will add them to our list – suggest those that you’d like to see

• you

– pick 10 presentations from these 30-50 – for each of these, you

• give a 2-3 sentence summary of its contents and
• write a critique: what was good, what could have been better
• taking into account all 3 aspects of a presentation

– storyline – slides – presenter

• submit these, then can see/compare with those from others

We will clarify this later. For now:

• no research symposium
• submit some presentation


via email to me

Deliverable 3

• you will give a 15 minute presentation
• about your research (PhD, previous, Tichy study)
• to a small group of ~13 fellow participants
• we discuss what
• worked well
• can be improved
• Later, we
• organise you into groups
• start scheduling your presentations
• First presentations:
• Thursday, April 20th

Voice coaching

• Who has attended the December session?

– what did you think?

• Who would like to attend a 


2 hour Voice Coaching Session?

– when would be a good time?

The Three Aspects

The speaker

• body language

– focus

• preparedness
• voice

– volume – speed – clarity

• nerves
• ...

The story

• story line
• clarity
• level
• timing
• use of terminology
• ...

The slides

• bullet lists
• graphics
• fonts
• highlights
• ...

Effects on you/audience by choices to these?
 What was helpful to get message across?

Coursework for Today

Make a

• 1. outline of your presentation

– following our skeleton above – with title slides and – core concepts/slogans per slide

• 2. list of your terminology

– specialist terms that you need in 
 your presentation

• 3. suitable running example
• Roughly 1 page

Discussion:

• Pair up
• Discuss for ~5min:
• storyline
• list of terms
• running example
• Then swap
• Is something

? missing ? too long ? too short

• Is example

? big enough ? small enough

• Setting the scene:

– what kind of problem is addressed? – why is that interesting/relevant?

• Focus:

– your Research Hypothesis/Question?

• Methodology/approach/work done:

– what have you done/are you doing?

• Context:

– how does this relate to other people’s work?

• Contributions made:

– what is the outcome of the work done? – what are the new insights gained? – how do these answer research hypothesis/question?

• Outlook/next steps/open questions?

Aspect 3: Slides for a good presentation

Yes, we’ll discuss Aspect 3 before Aspect 2

Slides for Good Presentations are

• pretty

– by being clutter free

• clear

– suitable layout & grouping mechanisms – no superfluous ink

• support the story

– helpful graphics – main points & keywords

• don’t distract

– no complete sentences

Ontology Diffing

pretty - aesthetically pleasing:

• helps understanding
• attracts interest
• raises expectations
• makes audience keen to listen

Slides for Good Presentations are

are clear:

• serve as handrail for presenter & audience

– contain well-designed graphics to illustrate certain points

• should not:

– distract from presenter – confuse

• ... we need to avoid

– visual noise – background graphics – un-necessary ink

Slides for Good Presentations

???

Graphics

“a picture can say more than 1,000 words”:

• enhances re-call

– amplified under short exposure

…but they need to be done properly:

• think of the purpose, message of picture
• make sure that this message becomes clear
• again, use as little ink as possible

19

Graphics and Tables

• require a lot of thought & care for choosing

– what to display – format (see last slides) – colour - use wisely! – captions, axis titles, etc

• can reader understand what is being shown?

– can they read numbers: is 72348765 < 87623458? – how much eye movement & comparison is required?

Good graphics help us remember

• Use good graphics
• Repeat them (shrunk) to enhance recall!

Results

• Performance of FFNNs on Task 1

Results

• Performance of RNNs on Task 1

Grouping

Grouping can be done by

• proximity
• color
• region
• connectors

but you should only use 1 of these methods!

Text and Grouping

Bullet lists:

• the grouping method for text
• make sure grouping

– is logical

• items on same level are of the same kind
• sub-items related to super item

– is not too deep – has no “lonely” items: these are rarely logical

• (again) minimize ink: avoid duplicating words
• no complete sentences/telegram style:

avoid multi-line items like the plague

Ontology

• represents

– agreement, – terminology, or – nomenclature

• contains

– extensive domain knowledge and/or – known facts/assertions

• enables

– semantic metadata extraction from data – resolution of semantic heterogeneity – semantic integration – semantic correlation of objects and documents un- or semi- structured

Which slide looks clearer?

Fonts

• Choose 1 font for all slides
• Careful: projector’s resolution is often poor

– un-serifed (sans serif): serifs are no good on screen – readable: cornet vs comet — dark vs clark vs dork – Arial, Computer Modern Sans, Helvetica, etc.

• Large enough letters

Fonts and Emphasis

• Choose 1 pattern for emphasis and stick to it:

– for emphasis: bold or color ...careful: might do the converse! – for new terms/quotes/names: italic – no underlining! – NO CAPITALIZING!

• .... and really stick to it

Animation?

• can be great to

– illustrate an algorithm running – show behaviour of example – build up complex picture – ...

• otherwise it creates

– useless noise – distraction from speaker

Discuss: making bullet points appearing 


• ne-by-one is great!

Which tool to use for your slides?

• Beamer (with Latex)
• Latex other
• Keynote
• Powerpoint
• Prezzie
• HTML other
• something else

My view: 
 Each of these can be used well/badly Discuss briefly!

Summary: your slides should…

• be clear & pretty

– not distracting – not puzzling – not confusing – not making viewers eyes move too much

• contain illustrations to

– support your points/findings – help audience understand & remember

Preview of Aspect 2: Some considerations regarding 
 the presenter

Some considerations

• What to wear?
• How to stand?

– where are your hands?

• Where to look?
• How to avoid nerves?

– what happens if you are nervous? – how do you deal with this?

• How to speak?

Making your voice heard

Breath. Talk

• at the right speed (requires practice & preparation)
• with breaks so that

– you can breathe – the audience can think

• in an audible way

– loud/at the right volume – clear/no mumbling

• following your well thought through narrative

– structured in a suitable way – with suitable transitions

• (again) to the audience!

To do for Wednesday

Coursework for Wednesday

• 1. Email me your favourite video lectures

to be included in our “critiques” exercise

• 2. Prepare and bring
• an improved story line, example, terminology

– taking into account feedback from today

• 3 good slides you want to use for your presentation

– not the title slide – some with graphics – some with texts – on your laptop or as print-out or on a memory stick.

• We will discuss these on Wednesday
