Learning and Optimization with 3D Orientations

There exist numerous ways of representing 3D orientations. Each representation has both limitations and unique features. Choosing the best representation for one task is often a difficult chore, and there exist conflicting opinions on which representation is better suited for a set of family of tasks. Even worse, when dealing with scenarios where we need to learn or optimize functions with orientations as inputs and/or outputs, the set of possibilities (representations, loss functions, etc.) is even larger and it is not easy to decide what is best for each scenario. In this paper, we attempt to a) present clearly, concisely and with unified notation all available representations, and "tricks" related to 3D orientations (including Lie Group algebra), and b) benchmark them in representative scenarios. The first part feels like it is missing from the robotics literature as one has to read many different textbooks and papers in order have a concise and clear understanding of all possibilities, while the benchmark is necessary in order to come up with recommendations based on empirical evidence. More precisely, we experiment with the following settings that attempt to cover most widely used scenarios in robotics: 1) direct optimization, 2) imitation/supervised learning with a neural network controller, 3) reinforcement learning, and 4) trajectory optimization using differential dynamic programming. We finally provide guidelines depending on the scenario, and make available a reference implementation of all the orientation math described.


Modeling and Control Framework for Autonomous Space Manipulator Handover Operations

Quevedo, Diego, Hudson, Sarah, Kim, Donghoon

arXiv.org Artificial Intelligence

Autonomous space robotics is poised to play a vital role in future space missions, particularly for In-space Servicing, Assembly, and Manufacturing (ISAM). A key capability in such missions is the Robot-to-Robot (R2R) handover of mission-critical objects. This work presents a dynamic model of a dual-arm space manipulator system and compares various tracking control laws. The key contributions of this work are the development of a cooperative manipulator dynamic model and the comparative analysis of control laws to support autonomous R2R handovers in ISAM scenarios. INTRODUCTION The global space industry has grown significantly over the past decade and is expected to continue expanding. In-space Servicing, Assembly, and Manufacturing (ISAM) is emerging as a transfor-mative approach to space operations.

Why Diffusion Models Don't Memorize: The Role of Implicit Dynamical Regularization in Training

Bonnaire, Tony, Urfin, Raphaël, Biroli, Giulio, Mézard, Marc

arXiv.org Machine Learning

Diffusion models have achieved remarkable success across a wide range of generative tasks. A key challenge is understanding the mechanisms that prevent their memorization of training data and allow generalization. In this work, we investigate the role of the training dynamics in the transition from generalization to memorization. Through extensive experiments and theoretical analysis, we identify two distinct timescales: an early time $τ_\mathrm{gen}$ at which models begin to generate high-quality samples, and a later time $τ_\mathrm{mem}$ beyond which memorization emerges. Crucially, we find that $τ_\mathrm{mem}$ increases linearly with the training set size $n$, while $τ_\mathrm{gen}$ remains constant. This creates a growing window of training times with $n$ where models generalize effectively, despite showing strong memorization if training continues beyond it. It is only when $n$ becomes larger than a model-dependent threshold that overfitting disappears at infinite training times. These findings reveal a form of implicit dynamical regularization in the training dynamics, which allow to avoid memorization even in highly overparameterized settings. Our results are supported by numerical experiments with standard U-Net architectures on realistic and synthetic datasets, and by a theoretical analysis using a tractable random features model studied in the high-dimensional limit.


General Transform: A Unified Framework for Adaptive Transform to Enhance Representations

Budiutama, Gekko, Daimon, Shunsuke, Nishi, Hirofumi, Matsushita, Yu-ichiro

Discrete transforms, such as the discrete Fourier transform, a re widely used in machine learning to improve model performance by extracting mea ningful features. However, with numerous transforms available, selectin g an appropriate one often depends on understanding the dataset's proper ties, making the approach less effective when such knowledge is unavailable. In th is work, we propose General Transform (GT), an adaptive transform-ba sed representation designed for machine learning applications. Unlike convent ional transforms, GT learns data-driven mapping tailored to the datase t and task of interest. Here, we demonstrate that models incorporating GT o utperform conventional transform-based approaches across computer v ision and natural language processing tasks, highlighting its effectiveness in diverse learning scenarios.
