What is Adaptation and Personalization?

Slide 1
Adaptation
• Change a system’s look• Change a system’s behaviour
• Based on contextual factors
Slide 2
Personalization

Personalisation
• Change a system’s look• Change a system’s behaviour
• Based on the personal profile of a system user– Preferences– User-behaviour
Slide 4
Personalisation is a special form of
Adaptation
Slide 5
Automatic Adaptive
Automatic non-adaptive systems
• Independent of environmental factors
• Fixed rules• Not aware of history
Adaptive systems
• Influenced by environmental factors
• learning application• History aware
Slide 6
Both types of systems can “feel” personalized
Controlling the Adaptation
All adaptive systems are based on two control mechanisms
• Adaptive Rules
• Adaptation strategy
Slide 7
Definition: Adaptation Rule
• Defines the conditions when the adaptation has to take place
• Defines what kind of adaptation will happen
Slide 8
Definition: Adaptation Strategy
A collection of adaptation rules that defines
• When and how a system reacts on environmental factors
• When and how a system takes the history into account
• Relation between the adaptation rules

Self-organizing system
• Detects appropriate adaptation rules
• Develops adaptation strategies dynamically
• Based on empirical analysis and pattern detection of input information
Slide 11
Pre-designed system
• Based on designed adaptation rules
• Based on designed adaptation strategies
• No automatic improvement of rules and strategies
Slide 12
User configured system
• User configurations influence the behavior of the system
• User can influence actively the adaptation process
Slide 13Training and formative evaluation sessions 2010
User customized system
• User can change some parameters of a system (e.g. background color)
• System logic is not influenced by the user

Levels of Adaptation
• First-order adaptation: adaptation strategy defines how a system has to adapt
• Second-order adaptation: the adaptive strategy itself is adaptive
Slide 17
GRAPPLE Scope
First-order user-adaptive systems
• Environmental factors are focused towards the person who uses the system
• History reflects how the system has been used by a person
