The document, presented by Memi Beltrame at UxCamp Switzerland, introduces machine learning concepts to designers, emphasizing its impact on design that is becoming physical, automated, and connected. It outlines three primary learning methods: supervised learning, unsupervised learning, and reinforcement learning, detailing their applications in sectors such as market segmentation, fraud detection, and predictive analytics. Additionally, it highlights the importance of ethical considerations in machine learning and encourages designers to engage actively in the AI design process to create empowering products.

Unsupervised learning The machine is given a lot of data and it
uses algorithms to find out interesting
patterns.

With these groups you now can direct address the different groups
The group on the top right probably are big households you can target
specifically
The group on the left are those that order less frequently so you could address
this and offer a super tuesday for those that don't order on that day
The last one is for the people that love boring pizza: give them what they want,
but larger!
The applications of this clustering by unsupervised learning are market
segmentation or fraud detection in banking

24. 3 methods how machines learn
Supervised learning You train the machine with data
The machine learns to make predictions
Unsupervised learning The machine is given a lot of data and it
uses algorithms to find out interesting
patterns.
Reinforcement learning The machine continuously learns from the
environment in an iterative fashion.
It starts dumb and gets smarter.

25. Reinforcement Learning
The machine is given a
set of rules and a goal
• Physics: Gravity etc
• Wheels turn
• Goal get farther than
previous cars
It trains itself by keeping
the features that helped
it reach the goal.

33. machines use algorithms
to make predictions

34. how machines use algorithms
1. Take a lot of training data
2. Pass it through a generic algorithm
(some mathematical formula)
3. Let the machine figure out its own
logic based on the data.
Emails
Generic Machine
Learning Algorithm
Spam Not Spam

35. how machines use algorithms
500g white flour,
2 tsp salt
7g fast-action yeast
3 tbsp olive oil
300ml water
475g plain flour,
1 tsp salt
10g dried yeast
1 tbsp olive oil
400ml water
The algorithm finds the valid weights of the individual
features of a data-set to make the right prediction
2 cups flour,
1 cup salt
1 tsp olive oil
1 cup water
Bread Bread Salty play dough

36. generic algorithms
There are many generic
algorithms that already exist.
The same generic algorithm
can be used to solve
problems in completely
different areas.
Emails Algorithm
Spam
Not Spam
Articles Algorithm Finance
Politics
Sports

37. 2 types of algorithms
Classification algorithms
Emails Algorithm
Spam
Not Spam
The goal is to predict discrete
values, e.g. {1,0}, {True, False},
{spam, not spam}.
Regression algorithms

The goal is to predict continuous
values, e.g. home prices, weather

A big part of ML
is about classification

38. image recognition
Chihuahua or Muffin?
Most image recognition is
about classification

39. image recognition
Real time

For a varying number of
recognizable elements

40. What about language?

41. is language like images?
Images can be
recognized
because their data
can be encoded
Can we do the same with language?

42. translation versus conversation
Do you have the time?
Translation goal:
Produce an equivalent
Conversation goal:
Understand the meaning
Avez-vous l’heure? It’s 7pm.Yes

43. statistical translation

44. statistical translation
Each word of the sentence can have several meanings.

45. statistical translation
I try | to run | at | the prettiest | open space.
I want | to run | per | the more tidy | open space.
I mean | to forget | at | the tidiest | beach.
I try | to go | per | the more tidy | seaside.
I want | to go | to | the prettiest | beach.
The algorithm compares the possible translations against existing ones.
The algorithm picks the translation with the highest probability.

48. Audio Text
conversational interfaces
Machine learning is a crucial
part of these interfaces

49. new challenges and disciplines
• recognizing intent
• understanding context
• voice and tone
• shaping conversations in a
humane and ethical way
}Linguistics
Ethics

50. intent - what does it all mean?
types of meaning
understand the wordsliteral:
understand the actual meaningimplied:
Do you have the time?
metaphors & metonymiesreferenced:
Wall Street is in crisis

52. Elements that make
this artificial:
• Not picking up intent
„give me a spot on saturday“
• Literal repetition

53. context
context is even harder than intent
• the sequence in time
• understanding the surroundings
• semantic context
homonymy: " is not a #

54. voice and tone: change registers
we adapt the way we speak to the
situation we’re in
Depending on:
• how serious the situation is
• how formal it is
• how we are connected to the person
Conversational interfaces need to take
this into account.

55. The designers’ role:
Assisted Intelligence

56. Designers are content experts
Icons by Sarah Rudkin
Developers
Build the machine
Domain experts
Have the domain
specific knowledge
Designers
• Content oversight for training:
What makes good training data?
• Mediator between engineering and domain
experts
• Ethical considerations

57. ethics matter
Machines learn from us
We choose what to teach
We need to
• challenge and stress test from a diverse
point of view
• put humans before technology
(once again)
• bring our principles of what good
design is to the AI world
This is a design task

58. Machine Learning is
everywhere
Learn to see its opportunities
Get a seat at the table now
Understand the implications
of using machine learning
Bring Design principles into the
mix to make empowering and
ethical products
