A note on submodular function minimization by Chubanov’s LP algorithm [PDF]
Recently Dadush et al. (2017) have devised a polynomial submodular function minimization (SFM) algorithm based on their LP algorithm. In the present note we also show a weakly polynomial algorithm for SFM based on the recently developed linear ...

On the Non-Submodularity of the Problem of Adding Links to Minimize the Effective Graph Resistance
We consider the optimisation problem of adding $k$ links to a given network, such that the resulting effective graph resistance is as small as possible.

Dynamic Stepsize Techniques in DR-Submodular Maximization
The Diminishing-Return (DR)-submodular function maximization problem has garnered significant attention across various domains in recent years. Classic methods often employ continuous greedy or Frank–Wolfe approaches to tackle this problem; however, high

Multimodal Hierarchical Dirichlet Process-Based Active Perception by a Robot
In this paper, we propose an active perception method for recognizing object categories based on the multimodal hierarchical Dirichlet process (MHDP). The MHDP enables a robot to form object categories using multimodal information, e.g., visual, auditory,

A capacity scaling algorithm for convex cost submodular flows
This paper presents a scaling scheme for submodular functions. A small but strictly submodular function is added before scaling so that the resulting functions should be submodular.

Robust team assignment and scheduling for scalable digital art collaboration [PDF]
Collaborative digital content creation in multi-stage artistic workflows requires effective coordination among heterogeneous creators and shared computational resources. However, many existing approaches overlook key constraints, such as cross-stage team

Submodular Optimization with Submodular Cover and Submodular Knapsack Constraints
We investigate two new optimization problems — minimizing a submodular function subject to a submodular lower bound constraint (submodular cover) and maximizing a submodular function subject to a submodular upper bound constraint (submodular knapsack ...

Extended Deep Submodular Functions
We introduce a novel category of set functions called Extended Deep Submodular functions (EDSFs), which are neural network-representable. EDSFs serve as an extension of Deep Submodular Functions (DSFs), inheriting crucial properties from DSFs while addressing innate limitations.
