## Zugzwang Meetings ### 2023-02-28 | 15:00 | Looking for Application Examples > What **applications** are we looking for? > - (Stochastic) Plan Generation > - Yale-Shooting Problem > - (Stochastic) Situation Calculus > - Frame Problem > - Given a **Bayesian Network** (or a **Markov Networks**): > - Represent it. > - Solve the common probability tasks: marginals, conditionals, parameter learning, inferring unobserved variables, sample generation, _etc._ > - Given a _solved_ ASP specification: > - What is the marginal probability of the atom `a`? > - What other probability queries are important to consider? > - Given an _unsolved_ ASP specification: > - What is the probability (distribution?) of the probabilistic fact `a`? > - What other questions are relevant? E.g. the distribution family of a fact? > - Given a _solved_ ASP specification and a set of _samples_: > - How do the probabilities inferred from the specification match the ones from the empiric distribution? > - Given two _solved_ ASP specification and a set of _samples_: > - Which specification best describes the empiric distribution? > > What should be the **task for the scholarship student**? _Use the `Python` API of `clingo`._ > 1. Read a string and extract probability annotations; Associate those annotations with the respective atoms. > 2. Call `clingo` to get stable models. > 3. Support **computation of the equivalence classes**: _Which functions and relations?_ > 4. Compute event probability using _weighted model counting_ on the equivalence classes. > 5. Read a Bayesian Network from a file (`BIF`, `DSC`, `NET`, `RDA`, `RDS`, ...) and generate an annotated "ASP" specification. > > 2022 | AAAI | Inference and Learning with Model Uncertainty in Probabilistic Logic Programs > - Is **"Epistemic Uncertainty (EU)"** the right framework for Zugzwang? How relevant are the epistemic questions in this paper to our work? > - EU can be represented by _Credal Sets, Subjective Logic_ and _Beta Distributions_? > - **Experiments** made with BNs from [(Kaplan and Ivanovska 2018)](https://www.sciencedirect.com/science/article/pii/S0888613X17302384) and larger networks from the [BNLearn repository](https://www.bnlearn.com/bnrepository). > - **Are networks, Bayesian Networks in particular, a "good enough" pool of "example applications" to us, for now?** ### 2023-01-10 | 15:00 - Paper - Project - Latent Facts ### 2022-12-12 - Is the project proposal ok? How long/detailed should it be? - Initial exploratory code `event_lattice.py` and `EventLattice.ipynb` done. - Start writing paper: Introduction, state of the art, motivation - Identify key problems - Target Conferences - KR; - [ICLP](https://waset.org/language-planning-conference-in-april-2023-in-lisbon); - [ECAI](https://ecai2023.eu/) - Next task for prototype: - Get stable models from potassco/s(casp) - other? ### 2022-12-05 - Created shared folder (gdrive:zugzwang) - Refine project tasks, for Bachelor, M.Sc., Ph.D. students and for researchers.
