Analytical – problem solvingCreative – ability to adapt to new situationsPractical – every day tasks

Defining creativity
Creativity is the ability to create ideasNew (to whom?)ValuableNovel
Evaluating Innovation
Relevance/effectiveness – does it solve the problemNovelty – is the idea unique, original, surprisingElegance – does the idea look finishedGenesis – does this idea inspire new ideas

How computers are creative
Blackboard systems – a group of experts (KS), in various disciplines are in a room with one blackboard.A problem is written on the blackboardEach experts writes parts of a solution on the board (KSI) using what previous experts have written.
Knowledge source
Depth first search – search along one path choosing the next node based on a heuristic function.Breadth first search – useful for gathering many alternative solutionsIncremental search – there is some prior knowledge of the search space, therefore the search space can be expanded as neededDifferential diagnostic search – directed differentiation among alternatives, process by elimination
algorithm for poetry generation
1. User inputs the text and constraints.2. Repeat Steps 3-6 until the termination condition is fulfilled.3. Blackboard monitor monitors the blackboard to see when something has changed or if one of the following termination criteria is satisfied:(a) The target number of poetry lines has been produced.(b) There are no pending KSIs in the agenda. If either of these conditions is satisfied, the generation process is stopped.

4. As a new event occurs on an abstraction level A, experts interested in this level are triggered by the monitor.(a) Each triggered expert provides the monitor with its list of preconditions.(b) The monitor checks if the preconditions are satisfied.(c) If the expert’s preconditions are satisfied, a knowledge source instance (KSI) is produced, containing expert’s name and the part of blackboard to which it will contribute (for example: “Collocation Expert: epithet” ).(d) KSI is added to the agenda.5. Control component schedules the KSIs on the agenda according to the following rules:(a) KSIs contributing to lower levels of abstraction are executed first.(b) For levels 1-6: KSIs working on one level are scheduled according to the size of the subareas they want to contribute to (KSIs pending to contribute to “emptier” subareas will be executed first)(c) For level 7: Control-level experts are scheduled according to a predefined order.

6. KSIs on the agenda are executed sequentially according to their order.7. If a new KSI is produced, all KSIs on the agenda are rescheduled.

Can computers be creative
Can computational creativity help us understand human creativity?Could computers (now or in the future) ever do things that appear to be creative?Could a computer appear to recognize creativity?Could computers themselves ever really be creative?
