Overall course focus: (hmm…)

  1. Reinforcement learning.
  2. Concept formation and program synthesis.
  3. Adaptive and probabilistic logics.
  4. Mental development theory.

Notes:

  1. Universal Artificial Intelligence: universal induction, exhaustive program search and reinforcement learning algorithms Δ (TeXmacs source Δ)
  2. Techniques of Reinforcement Learning Δ (TeXmacs source Δ)
    1. RL_Ch6_Evolutionary_modular.pdf Δ
    2. RL_Ch7_Hierarchical_RL.pdf Δ
  3. General Game Playing Δ (TeXmacs source Δ)
  4. Knowledge Representation and Language Δ (TeXmacs source Δ)
  5. Adaptive and Probabilistic Logics for Reasoning Systems
    1. Adaptive (or Defeasible) Logics and OSCAR Δ (TODO: complete the notes about OSCAR)
    2. Frequency and/or Uncertainty Logics: Non Axiomatic Logic, Markov Logic Networks Δ, Probabilistic Logic Networks (to come)
    • I’ve presented OSCAR and comments on John Pollock’s theory supported by his slides and article figures, I also introduced “propositional” NARS
  6. Estimation of Distribution Algorithms and Genetic Programming Δ (TeXmacs source Δ)
  7. Inductive (Logic) Programming
  8. Spreading Activation: memory retrieval, distributed reasoning, action selection, probabilities Δ (work in progress) approaches based on spreading activation mechanism or strong biological inspirations
  9. The Representation and Acquisition of Concepts Δ (to come later)
  10. Cognitive Architectures

I’ve moved KR before logics to introduce representation means of representation-specific reasoning systems (NARS and PLN) there.

Considered:

  1. Values and Others: Grounding Agents in Game Semantics Δ (to come)
    • We build semantics in both representational and logic aspects based on the notion of agent specific rewards/motivations.
