Tractable Boolean and Arithmetic Circuits [article]

Adnan Darwiche
2022 arXiv   pre-print
Tractable Boolean and arithmetic circuits have been studied extensively in AI for over two decades now.  ...  These circuits were initially proposed as "compiled objects," meant to facilitate logical and probabilistic reasoning, as they permit various types of inference to be performed in linear-time and a feed-forward  ...  We saw in the previous section how counting the models of a tractable Boolean circuit is done through the application of arithmetic operations at Boolean gates: additions at or-gates and multiplications  ...

Neural Semirings

Pedro Zuidberg Dos Martires
2021 International Workshop on Neural-Symbolic Learning and Reasoning  
Usually, the reasoning task, e.g. probabilistic reasoning or fuzzy reasoning, is fixed upfront as part of the problem specification.  ...  From an abstract algebra perspective, reasoning tasks in symbolic artificial intelligence can be formulated in terms of commutative semiring operations.  ...  In the case of the Boolean literals representing probabilistic Boolean variables, the probability semiring allows for the computation of the probability of a Boolean function being satisfied: 𝑝( ⋁ 𝐼  ...

Comparing Boolean and probabilistic information retrieval systems across queries and disciplines

Robert M. Losee
1997 Journal of the American Society for Information Science  
The performance of models failing to meet statistical and other assumptions is examined.  ...  Using these performance predicting techniques, sample performance figures are provided for queries using the Boolean and and or, as well as for probabilistic systems assuming statistical term independence  ...  Statements composed of a single Boolean operator can be modeled probabilistically and compound Boolean statements can be treated as nested simpler Boolean expressions placed into CNF.  ...

On Tractable Representations of Binary Neural Networks [article]

Weijia Shi and Andy Shih and Adnan Darwiche and Arthur Choi
2020 arXiv   pre-print
We consider the compilation of a binary neural network's decision function into tractable representations such as Ordered Binary Decision Diagrams (OBDDs) and Sentential Decision Diagrams (SDDs).  ...  First, we consider the task of verifying the robustness of a neural network, and show how we can compute the expected robustness of a neural network, given an OBDD/SDD representation of it.  ...  In general, determining whether an input of a Boolean function is unate/monotone or unused are computationally hard problems.  ...
