Count Anything at Any Granularity

Researchers have introduced a new framework for open-world object counting, addressing the brittleness of current vision-language models in accurately identifying and counting objects based on user intent. They propose redefining counting as a multi-grained problem, where both visual examples and detailed text prompts, including negative prompts, specify the target appearance and semantic granularity. To overcome the data limitations for this approach, they developed an automated pipeline using 3D synthesis and VLM filtering to create KubriCount, the largest dataset for counting tasks. Their new model, HieraCount, leverages both text and visual exemplars to significantly improve multi-grained counting accuracy and generalize to real-world scenarios. AI

IMPACT Introduces a more robust method for object counting, potentially improving applications that rely on visual scene understanding and quantification.

Key-Value Means

Researchers have introduced Key-Value Means (KVM), a new attention mechanism for transformers that can handle both fixed-size and growing states. When implemented with a fixed-size cache, KVM functions as an O(N) chunked RNN with minimal parameter additions. A growable KVM cache version demonstrates competitive performance on long-context tasks, offering subquadratic prefill time and sublinear state growth. This approach is compatible with standard operations, supports chunk-wise parallelizable training, and provides a flexible trade-off between prefill time complexity and memory usage. AI

IMPACT Introduces a novel attention mechanism that improves transformer efficiency for long-context tasks.

I fine-tuned a bias judge for $30. The training was the easy part.

A developer fine-tuned Google's Gemma 4 E4B model into a bias judge for approximately $30, a process that took two weeks with most of the effort focused on data pipeline construction rather than GPU time. The resulting model, capable of running locally in 30 seconds, evaluates pairs of responses to identify social bias using the Bias Benchmark for QA (BBQ) dataset. The developer encountered challenges with classification leaks, data ceilings imposed by the BBQ dataset, and disagreements among different LLMs used for labeling, ultimately leading to a refined data construction strategy. AI

IMPACT Demonstrates cost-effective fine-tuning of open-source models for specialized tasks like bias detection, potentially lowering barriers for AI safety research.
