Morphable Diffusion: 3D-Consistent Diffusion for Single-image Avatar Creation
To the best of our knowledge, our proposed framework is the first diffusion model to enable the creation of fully 3D-consistent, animatable, and photorealistic human avatars from a single image of an unseen subject; extensive quantitative and qualitative evaluations demonstrate the advantages of our approach over existing state-of-the-art avatar creation models on both novel view and novel expression synthesis tasks.
3DGS-Avatar: Animatable Avatars via Deformable 3D Gaussian Splatting
In this paper, we use 3D Gaussian Splatting and learn a non-rigid deformation network to reconstruct animatable clothed human avatars that can be trained within 30 minutes and rendered at real-time frame rates (50+ FPS).
IntrinsicAvatar: Physically Based Inverse Rendering of Dynamic Humans from Monocular Videos via Explicit Ray Tracing
We present IntrinsicAvatar, a novel approach to recovering the intrinsic properties of clothed human avatars including geometry, albedo, material, and environment lighting from only monocular videos.
Large Language Models in Finance: A Survey
In this paper, we provide a practical survey focused on two key aspects of utilizing LLMs for financial tasks: existing solutions and guidance for adoption.
Synthesizing Diverse Human Motions in 3D Indoor Scenes
We present a novel method for populating 3D indoor scenes with virtual humans that can navigate in the environment and interact with objects in a realistic manner.
Self-Supervised Image Representation Learning: Transcending Masking with Paired Image Overlay
Self-supervised learning has become a popular approach in recent years for its ability to learn meaningful representations without the need for data annotation.
ARAH: Animatable Volume Rendering of Articulated Human SDFs
We demonstrate that our proposed pipeline can generate clothed avatars with high-quality pose-dependent geometry and appearance from a sparse set of multi-view RGB videos.
Compositional Human-Scene Interaction Synthesis with Semantic Control
Furthermore, inspired by the compositional nature of interactions that humans can simultaneously interact with multiple objects, we define interaction semantics as the composition of varying numbers of atomic action-object pairs.
Investor Behavior Modeling by Analyzing Financial Advisor Notes: A Machine Learning Perspective
With the help of natural language processing (NLP) we analyze an unstructured (textual) dataset of financial advisors' summary notes, taken after every investor conversation, to gain first ever insights into advisor-investor interactions.
MetaAvatar: Learning Animatable Clothed Human Models from Few Depth Images
In contrast, we propose an approach that can quickly generate realistic clothed human avatars, represented as controllable neural SDFs, given only monocular depth images.
Locally Aware Piecewise Transformation Fields for 3D Human Mesh Registration
We combine PTF with multi-class occupancy networks, obtaining a novel learning-based framework that learns to simultaneously predict shape and per-point correspondences between the posed space and the canonical space for clothed human.

This paper introduces a new set of video analytics plugins developed for the FFmpeg framework.
End-to-end Training of CNN-CRF via Differentiable Dual-Decomposition
These algorithms can efficiently and exactly solve sub-problems and directly optimize a convex upper bound of the real problem, providing optimality certificates on the way.
Accelerating Column Generation via Flexible Dual Optimal Inequalities with Application to Entity Resolution
We tackle optimization of weighted set packing by relaxing integrality in our ILP formulation.

To circumvent the difficulty of enumerating the vector product of state spaces of hyper-variables we introduce a novel Benders decomposition approach.
Efficient Multi-Person Pose Estimation with Provable Guarantees
We test our approach on the MPII-Multiperson dataset, showing that our approach obtains comparable results with the state-of-the-art algorithm for joint node labeling and grouping problems, and that NBD achieves considerable speed-ups relative to a naive dynamic programming approach.

To solve this integer program, we propose a column generation formulation where the pricing program is solved via exact optimization of very small scale integer programs.
Multi-Person Pose Estimation via Column Generation
We give a novel integer program formulation of the multi-person pose estimation problem, in which variables correspond to assignments of parts in the image to poses in a two-tier, hierarchical way.
