DyGRAV: Dynamic Grounding and Relational Reasoning for Vision–Language Navigation

Vision–Language Navigation (VLN) requires embodied agents to interpret natural-language instructions in 3D environments. While significant progress has been made, state-of-the-art agents often struggle with instructions that demand fine-grained visual understanding, correctly grounding specific object attributes, disti...

Gaussian Splatting for real-time scene reconstruction: Methods, systems, and trade-offs

3D Gaussian Splatting (3DGS) allows for high-quality real-time novel-view synthesis. Since its inception in 2023, its explicit and highly configurable scene representation has been extended toward sparse-view generation, dynamic reconstruction, efficiency and compression, streaming, and simultaneous localization and ma...

Smarter Chemical Oxygen Demand (COD) Prediction in Urban Wastewater Treatment Based on Post-Hoc Residual-Correction: A Comparative Machine Learning Analysis

The proposed Post-Hoc Residual Correction (PHRC) framework is presented and its performance against various ML models in predicting the effluent chemical oxygen demand (E-COD) of an urban sewage WWTP is evaluated.

Memory Consolidation Flattens the Temporal Shape of User Facts

Long-term memory systems turn conversations into short stored notes. A note can keep a user fact while losing evidence about whether the fact still holds. For example,"I am driving a Peugeot"can become"The user drives a Peugeot,"which drops the cue that the activity is ongoing. We call this aspectual flattening and mea...
