RADAR提出了一种高效的以能力为中心的评估框架,用于揭示多模态大语言模型预训练中感知和推理能力的非对称发展。

摘要:

预训练的多模态大语言模型(MLLMs)通过利用其固有的感知和推理能力,为后续训练提供知识丰富的基础,以解决复杂任务。然而,缺乏高效的评估框架阻碍了对其性能瓶颈的诊断。当前的评估主要依赖于监督微调后的测试,这引入了繁琐的额外训练和自回归解码成本。同时,常见的预训练指标无法量化模型的感知和推理能力。此外,现有的评估基准通常在规模上有限或与预训练目标不一致。因此,我们提出了RADAR,一种高效的以能力为中心的评估框架,用于揭示多模态大语言模型预训练中能力的非对称发展。RADAR包含两个关键组件:(1)软辨别分数,一种新的度量标准,用于在不微调的情况下稳健地跟踪能力发展,基于量化模型对正确答案与干扰项之间细微差异的偏好程度;(2)多模态混合基准,一个包含15000多个样本的新基准,用于在零样本情况下全面评估预训练的MLLMs的感知和推理能力,在此我们统一了权威基准数据集并精心收集了新的数据集,扩展了评估范围并解决了当前基准中的关键缺口。通过RADAR,我们全面揭示了预训练的MLLMs在数据量、模型大小和预训练策略等不同因素下的感知和推理能力的非对称发展。我们的RADAR强调了对预训练能力瓶颈的分解视角的重要性,为高效推进MLLMs提供了有针对性的干预。我们的代码已公开在https://github.com/Nieysh/RADAR。

英文摘要:

Pre-trained Multi-modal Large Language Models (MLLMs) provide a knowledge-rich foundation for post-training by leveraging their inherent perception and reasoning capabilities to solve complex tasks. However, the lack of an efficient evaluation framework impedes the diagnosis of their performance bottlenecks. Current evaluation primarily relies on testing after supervised fine-tuning, which introduces laborious additional training and autoregressive decoding costs. Meanwhile, common pre-training metrics cannot quantify a model's perception and reasoning abilities in a disentangled manner. Furthermore, existing evaluation benchmarks are typically limited in scale or misaligned with pre-training objectives. Thus, we propose RADAR, an efficient ability-centric evaluation framework for Revealing Asymmetric Development of Abilities in MLLM pRe-training. RADAR involves two key components: (1) Soft Discrimination Score, a novel metric for robustly tracking ability development without fine-tuning, based on quantifying nuanced gradations of the model preference for the correct answer over distractors; and (2) Multi-Modal Mixture Benchmark, a new 15K+ sample benchmark for comprehensively evaluating pre-trained MLLMs' perception and reasoning abilities in a 0-shot manner, where we unify authoritative benchmark datasets and carefully collect new datasets, extending the evaluation scope and addressing the critical gaps in current benchmarks. With RADAR, we comprehensively reveal the asymmetric development of perceptual and reasoning capabilities in pretrained MLLMs across diverse factors, including data volume, model size, and pretraining strategy. Our RADAR underscores the need for a decomposed perspective on pre-training ability bottlenecks, informing targeted interventions to advance MLLMs efficiently. Our code is publicly available at https://github.com/Nieysh/RADAR.
