23. Model Merging, Cross-Modal Coupling, Course Summary

Bayesian Story Merging

By using the probability model discovery previously studied, certain concepts and ideas can be analyzed and merged if similar.

Cross-Modal Coupling

By analyzing the correspondences between clusters of two sets of data, certain data subsets regular correspondences can be sorted out. According to Prof. Patrick Winston, this system of correspondences is very likely to be present in human intelligence.

Applications of AI

  • Scientific approach: understanding how AI works
  • Engineering approach: implementing AI applications

The most interesting applications are not to replace people with artificial intelligence but to work in tandem with people.

Using a lot of computing power and data becomes more common, but an interesting question is how little information is needed to work a certain problem.

Genesis system

The system translates stories into a internal language to understand stories and display them in diagrams. It allows to read stories on different levels, and use different “personas” to understand stories differently.

Humans may not be intelligent enough to build a machine that is as intelligent as them.

18. Representations: Classes, Trajectories, Transitions

Vocabulary

In a semantic net, a diagram of relations between objects, essential notions can be defined as follows:

  • Combinators: linking objects together
  • Reification: actions implying results
  • Localization: a frame where objects and actions happen
  • Story sequence: a series of actions happening linearly in time

Classification

In natural language, knowledge is generally organized from general categories to basic objects and finally specific objects.

Transition

Another element of language is recording change in the evolution of objects during the unfolding of stories.

Trajectory

Language also tracks movement in the description of actions.

An agent makes an object move from a source to a destination using a instrument. A co-agent may be involved, the action might be aimed towards a beneficiary, and the motion may be helped by a conveyance, etc. In English, preposition tend to be used to define the role of each part in the action, enabled recording of interactions.

Language corpuses, such as the Wall Street Journal Corpus, are generally composed of 25% of transition or trajectory.

Story sequences

Agents’ action determine transitions in the semantic net, which result in trajectories.

Story libraries

Each type of story implies a number of characteristics that correspond to the situation. Example: events can be disasters or parties, they have a time and place, involved people, casualties, money, places…
