What can be certified compactly? [article]

Nicolas Bousquet and Laurent Feuilloley and Théo Pierron
2022 arXiv   pre-print
These problems are typically those that can be expressed in some logic, and the graph structures are whose with bounded width or depth parameters.  ...  In the analogue setting of polynomial-time centralized algorithms, a very fruitful approach has been to prove that restricted types of problems can be solved in polynomial time in graphs with restricted  ...  One can locally encode and certify a spanning tree with (log ) bits. The number of vertices in the graph can also be certified with (log ) bits.  ...

What Can Be Certified Compactly? Compact local certification of MSO properties in tree-like graphs

Laurent Feuilloley, Nicolas Bousquet, Théo Pierron
2022 Proceedings of the 2022 ACM Symposium on Principles of Distributed Computing  
On trees, we prove that MSO properties can be certified with labels of constant size, whereas the typical non-MSO property of isomorphism requires Ω(𝑛) size certificates (where Ω hides polylogarithmic  ...  These problems are typically those that can be expressed in some logic, and the graph structures are those with bounded width or depth parameters.  ...  FO sentences with quantifier depth at most 2 can be certified with 𝑂 (log 𝑛) bits.  ...

Compactly Restrictable Metric Policy Optimization Problems [article]

Victor D. Dorobantu, Kamyar Azizzadenesheli, Yisong Yue
2022 arXiv   pre-print
We further show that our theoretical results on CR-MPOPs can be used to characterize feedback linearizable control affine systems.  ...  To do so, we define a special class of MPOPs called Compactly Restrictable MPOPs (CR-MPOPs), which are flexible enough to capture the complex behavior of robotic systems but specific enough to admit solutions  ...  We leverage recent results [7] , [8] to certify the existence of a compact subset of the state space that can be rendered forward-invariant through control.  ...

On the Separability of Unitarily Invariant Random Quantum States: The Unbalanced Regime

In the large matrix size limit, the distribution of these random quantum states is characterized by their limiting spectrum, a compactly supported probability distribution.  ...  With the help of free cumulants, we can introduce the free additive convolution of compactly supported probability measures, a notion which will play a key role in what follows.  ...  Assume ≥ 2 and let be a compactly supported probability measure such that Γ = .

Certifying Robustness to Programmable Data Bias in Decision Trees [article]

Anna P. Meyer and Aws Albarghouthi and Loris D'Antoni
2021 arXiv   pre-print
Datasets can be biased due to societal inequities, human biases, under-representation of minorities, etc.  ...  To certify robustness, we use a novel symbolic technique to evaluate a decision-tree learner on a large, or infinite, number of datasets, certifying that each and every dataset produces the same prediction  ...  If (4), then -since neither g 1 nor g 2 conditions on the label nor specifies what the new label can be -we can still flip the label twice and end up with the same configuration.  ...
