Robots That Reason: A New Approach to Following Instructions

December 27, 2025 by BBG News

An agent navigates and interacts with an environment through a cyclical process of planning and perception, beginning with an initial understanding of the surroundings and refining this knowledge through action and visual feedback, ultimately updating a scene memory graph to guide subsequent steps until a designated task is completed.

Researchers have developed a planning method that empowers robots to better understand dynamic environments and execute complex tasks by combining visual and linguistic information.

Smarter RL: Adapting to Complex Actions

December 27, 2025 by BBG News

The agent autonomously constructs state abstractions within a dynamic office environment, learning policies for multi-item delivery through parameterized actions-each defined by a precision-calibrated interval [latex] [a, b) [/latex], where the length [latex] b - a [/latex] directly reflects the granularity of control achieved in navigating the space.

A new reinforcement learning approach learns to simplify complex tasks by dynamically adjusting how it perceives states and actions, boosting performance and sample efficiency.

Motion from Meaning: Aligning Text and Human Movement

December 26, 2025 by BBG News

Complex motion is refined by decomposing it into temporally ordered segments and aligning these within a shared embedding space, ultimately enhancing both the accuracy and realism of generated movements.

Researchers have developed a new method for generating realistic 3D human motion directly from textual descriptions by focusing on precise temporal alignment between words and actions.

Beyond Sight: AI Agents Fill in the Gaps with Semantic Reasoning

December 26, 2025 by BBG News

The proposed framework achieves high-fidelity scene completion through a closed-loop reasoning process, beginning with holistic collaborative parsing of spatial geometry, followed by iterative verification to correct segmentation inaccuracies and address occlusions, and culminating in the generation of diverse, plausible semantic hypotheses before a single-pass synthesis of the completed scene-a process fundamentally grounded in the decoupling of semantic planning and visual synthesis.

A new framework combines the power of large language models and collaborative agents to achieve more human-like amodal completion, enabling AI to ‘understand’ obscured objects.

Decoding Movement: A New Approach to Action Recognition

December 26, 2025 by BBG News

The proposed method processes skeletal and feature data through separate spatial-temporal encoders to create decoupled representations, then employs Unimodal Feature Decomposition to refine comparisons and Multimodal Feature Composition to build late-fused features - a pipeline designed to leverage both individual and combined data streams for enhanced performance, acknowledging the inevitable complexities of multimodal integration.

Researchers have developed a self-supervised learning framework that breaks down and recomposes skeletal data to achieve a more robust understanding of human actions.
