Bridging the Activity Gap: Why AI Struggles with Aging

December 13, 2025 by BBG News

Behavioral models trained on data from younger individuals may falter when applied to older adults, as age-related shifts in behavioral distributions introduce unseen patterns and undermine the reliability of inferences made from training data.

New research reveals the challenges of deploying machine learning models for human activity recognition when training data doesn’t reflect the behavioral patterns of older adults.

Unlocking Scientific Knowledge with AI

December 13, 2025 by BBG News

SciEx establishes a structured workflow for extracting and synthesizing information from scientific PDFs, beginning with pre-processing and data segmentation, then employing a retrieval and verification module to respond to researcher queries-explicit or LLM-generated-and culminating in the aggregation of data across multiple documents into a unified, canonicalized JSON output, thereby enabling comprehensive knowledge discovery.

Researchers are harnessing the power of artificial intelligence to automatically extract structured data from the ever-growing body of scientific literature.

Bringing Brains to Bots: A New Framework for Intelligent Robotics

December 12, 2025 by BBG News

RoboNeuron employs a layered cognitive-execution architecture that strictly separates high-level orchestration from the execution environment, bridged by a semantic tool library and message translator which registers type-safe robotic functionalities, and manages execution through bifurcated pathways-a simple path for low-latency commands and a complex path for perception-action loops-before adapting standardized outputs for deployment across diverse platforms.

Researchers have developed a modular system that seamlessly integrates the power of large language models with the widely used Robot Operating System, unlocking new potential for adaptable and efficient robot behavior.

Building with Blocks: How Analogical Reasoning Powers AI Creativity

December 12, 2025 by BBG News

Without accounting for temporal relationships within a prompt, the model struggles to establish connections between described objects, and lacking sparsity regularization allows individual prompts to exert disproportionate influence-illustrated by attention maps that inappropriately highlight irrelevant elements-but the integration of both time-dependence and sparsity regularization enables HierDiff to synthesize images that faithfully reflect complex textual instructions.

New research reveals that the ability to generalize to novel combinations of concepts relies on principles of causal modularity and minimal change, offering a pathway to more robust and creative AI systems.

Brazil’s Bot Wars: How Automation Amplified Voices in the 2018 Election

December 12, 2025 by BBG News

Analysis of social media sentiment surrounding the 2018 Brazilian presidential election reveals distinct trends between accounts classified as likely bots-using BotometerLite thresholds of 0.5, 0.7, and 0.9-and those identified as human-generated, suggesting potential manipulation or amplification of specific viewpoints through automated accounts, as evidenced by differing fourteen-day moving average sentiment scores.

A new study reveals how social bots functioned as echo chambers during Brazil’s 2018 elections, primarily boosting specific candidates and narratives rather than driving independent conversation.

Seeing, Understanding, and Acting: A Leap Forward in Robotic Manipulation

December 12, 2025 by BBG News

The BEHAVIOR Challenge dataset, designed for the NeurIPS 2025 competition, exhibits a distribution of skill occupancy across video frames and reveals that trajectories vary in length and complexity, averaging a specific number of frames and unique skills per instance-characteristics inherent to any system navigating a finite state space before inevitable decay.

Researchers have significantly improved a robot’s ability to perform complex, long-horizon tasks by combining advanced vision-language understanding with a novel reinforcement learning technique.

When AI Values Collide: The Rise of Diverse Collective Intelligence

December 12, 2025 by BBG News

Constitutional rule ideologies diverge between groups, while agent values demonstrably correlate with the types of ideological rule embraced.

New research reveals that intentionally fostering a diversity of values among artificial intelligence agents can lead to more effective collaboration and the emergence of complex, self-governing communities.
