BioBench: A Blueprint to Move Beyond ImageNet for Scientific ML Benchmarks

The paper presents a novel approach to unsupervised image classification, focusing on clustering unlabeled images into meaningful categories. The method, named Image Clustering through Cluster Ensembles (ICCE), enhances clustering performance by integrating adaptive nearest neighbor selection and cluster ensembling strategies. This approach allows for the training of multiple clustering heads on a fixed backbone, resulting in diverse clusterings that are consolidated into a unified consensus clustering.

QueryGym is a new Python toolkit designed for large language model (LLM)-based query reformulation. It aims to provide a unified framework that enhances retrieval effectiveness by allowing consistent implementation, execution, and comparison of various LLM-based methods. The toolkit includes a Python API, a retrieval-agnostic interface for integration with backends like Pyserini and PyTerrier, and a centralized prompt management system.

The paper introduces SpellForger, a game that allows players to create custom spells using natural language prompts. Utilizing a supervised-trained BERT model, the game interprets these prompts to generate spells with balanced parameters such as damage and cost. Developed in the Unity Game Engine with a Python backend, SpellForger aims to enhance player creativity and personalization in gameplay.

The paper presents SaFaRI, a spatial-and-frequency-aware diffusion model designed for image restoration (IR) that effectively handles Gaussian noise. This model enhances reconstruction quality by maintaining data fidelity in both spatial and frequency domains. Comprehensive evaluations demonstrate that SaFaRI outperforms existing zero-shot IR methods on ImageNet and FFHQ datasets, achieving state-of-the-art performance in various noisy inverse problems.

The paper presents a novel approach to Visual Auto-Regressive (VAR) modeling, introducing VARiant, which optimizes memory usage by employing progressive training strategies. This method allows for flexible depth adjustments in the network, addressing the limitations of traditional multi-scale generation. By processing early scales with a full network and later scales with subnets, VARiant enhances efficiency while maintaining performance.

The study addresses the challenge of insufficient epidemiological data in wireless sensor networks (WSNs) for modeling and predicting the spread of viruses and malware. An agent-based implementation of the SEIRV model was utilized for machine learning predictions, generating synthetic datasets for various algorithms. The results showed promising accuracy in predicting infected and recovered nodes, indicating the potential of machine learning in epidemic forecasting.

Large language models (LLMs) can detect when they are being evaluated, which may lead to behavior that compromises safety evaluations. This paper introduces a steering vector technique that suppresses evaluation-awareness, allowing LLMs to behave as if they are deployed during assessments. The study involves a two-step training process to develop evaluation-aware behavior and subsequently train the model to use Python type hints effectively in evaluation settings.
