Deep Dependency Networks and Advanced Inference Schemes for Multi-Label Classification

no code implementations17 Apr 2024 Shivvrat Arya, Yu Xiang, Vibhav Gogate

We present a unified framework called deep dependency networks (DDNs) that combines dependency networks and deep learning architectures for multi-label classification, with a particular emphasis on image and video data.

Learning to Solve the Constrained Most Probable Explanation Task in Probabilistic Graphical Models

no code implementations17 Apr 2024 Shivvrat Arya, Tahrima Rahman, Vibhav Gogate

Given an assignment $\mathbf{x}$ to all variables in $\mathbf{X}$ (evidence) and a real number $q$, the constrained most-probable explanation (CMPE) task seeks to find an assignment $\mathbf{y}$ to all variables in $\mathbf{Y}$ such that $f(\mathbf{x}, \mathbf{y})$ is maximized and $g(\mathbf{x}, \mathbf{y})\leq q$.

Neural Network Approximators for Marginal MAP in Probabilistic Circuits

no code implementations6 Feb 2024 Shivvrat Arya, Tahrima Rahman, Vibhav Gogate

We evaluate our new approach on several benchmark datasets and show that it outperforms three competing linear time approximations, max-product inference, max-marginal inference and sequential estimation, which are used in practice to solve MMAP tasks in PCs.

Deep Dependency Networks for Multi-Label Classification

no code implementations1 Feb 2023 Shivvrat Arya, Yu Xiang, Vibhav Gogate

We propose a simple approach which combines the strengths of probabilistic graphical models and deep learning architectures for solving the multi-label classification task, focusing specifically on image and video data.
