Lost in Translation: How Stories Created by AI Reflect Cultural Blind Spots

November 30, 2025 by BBG News

Through focus groups and surveys, a taxonomy of cultural misrepresentation was developed, subsequently quantified via large-scale annotation, and then leveraged to construct a dataset-TALES-QA-designed to assess the cultural knowledge embedded within language models.

New research reveals that despite possessing vast knowledge, AI storytellers often perpetuate cultural misrepresentations, particularly when venturing beyond Western narratives.

Tracking Actions in Detail: A New Approach to Video Understanding

November 30, 2025 by BBG News

The Action-Region Tracking (ART) framework addresses limitations in standard action prediction by focusing on evolving, discriminative regions within a scene-represented as $Tr$ features refined from semantic features $X$ extracted by a backbone network-rather than relying on easily distinguishable, yet often static, areas highlighted by the backbone alone, thereby enabling a more nuanced understanding of action dynamics over time.

Researchers have developed a novel framework that focuses on tracking specific regions of interest within videos to achieve more accurate fine-grained action recognition.

Seeing the Unseen: AI Reconstructs Hidden Shapes from Scattered Waves

November 30, 2025 by BBG News

Electromagnetic scattering is demonstrated around a doubly-connected magneto-dielectric cylinder, with three-dimensional modeling and cross-sectional analysis revealing the interaction’s characteristics.

A new deep learning approach leverages convolutional neural networks to accurately determine the geometry and material properties of obscured objects from electromagnetic scattering data.

Beyond Pairwise: Scaling Multimodal Learning with Contrastive Fusion

November 30, 2025 by BBG News

ConFu establishes a framework for multimodal alignment by simultaneously contrasting paired modalities and aligning each to a fused representation of the others, ultimately minimizing a combined loss function - $ \mathcal{L} $ - balanced by a weighting factor $ \lambda $ to govern the influence of pairwise $ \mathcal{L}\_{pair} $ and fused $ \mathcal{L}\_{fused} $ objectives.

A new framework, Contrastive Fusion, leverages both pairwise and higher-order relationships to significantly enhance multimodal representation learning.

Beyond Brute Force: Can Specialized AI Models Combine to See Like a Generalist?

November 30, 2025 by BBG News

The EoS-FM Backbone dynamically adapts inputs through strategic band duplication and selection, extracting a maximum number of feature maps-each encoder producing $n$ maps-before intelligently fusing a chosen subset of $k$ encoders into a consolidated set of $n$ fused feature maps destined for the decoder.

A new approach to remote sensing foundation models demonstrates that an ensemble of focused AI experts can achieve competitive performance with dramatically reduced computational demands.

Adapting Prompts for Smarter Vision AI

November 30, 2025 by BBG News

The training process refines foundational “anchor tokens” through large language model-guided optimization-effectively freezing a knowledge base-before adapting soft prompts and positional encoding for downstream tasks, with ensemble distillation serving as a guiding influence during this refinement stage.

A new framework dynamically adjusts prompt tokens to unlock better performance and generalization in vision-language models.

Beyond the Missing Pieces: Reimagining Image Editing with Generative Models

November 30, 2025 by BBG News

The study contrasts a standard image-mask context-typically employed in diffusion-based inpainting, denoted as $c^{b}\_{I-M}$-with a proposed context for image layer decomposition, represented as $\{c^{f}\_{I-M},c^{b}\_{I-M}\}$, highlighting a shift in how masked image regions are interpreted during the decomposition process.

Researchers are demonstrating that techniques originally developed for image inpainting can be powerfully repurposed for the complex task of decomposing images into their constituent layers.

Beyond the Image: How Comparing AI Generations Reveals Hidden Biases

November 30, 2025 by BBG News

MIRAGE facilitates a comparative analysis of text-to-image models by prompting users to articulate expectations before viewing generated content, initially revealing outputs from a single model, then presenting a full comparative view, and ultimately encouraging detailed evaluation of model performance against initial prompts and previously unnoticed details-a process designed to expose the nuances of generative AI and refine user understanding of model behavior.

A new study demonstrates that directly comparing outputs from text-to-image models fundamentally changes how users evaluate and understand their underlying behaviors.

Teaching AI to Think Like Us: The Promise of Limited Data

November 30, 2025 by BBG News

The divergence in simulated beliefs, as measured by the Jensen-Shannon distance, reveals how varying finetuning strategies impact large language models’ representation of beliefs across different ethnic groups, suggesting that even sophisticated models struggle to replicate nuanced human perspectives without careful calibration.

New research explores whether refining large language models with small amounts of human behavioral data can improve their ability to simulate human reasoning and decision-making.
