| ### Abstract |
|
|
| As multi-modal models advance towards long-form video understanding, memory emerges as a critical capability. Despite substantial effort in developing video datasets and benchmarks, existing work primarily focuses on perception and reasoning, without systematically evaluating memory: what models retain, how faithfully information is preserved, and how robust memory remains under interference. |
|
|
| To address this gap, we introduce M³Eval, the first comprehensive evaluation framework and benchmark for probing different memory dimensions in multi-modal models. |
|
|
| Grounded in cognitive psychology, our design features carefully constructed tasks isolating key aspects of memory. Leveraging M³Eval, we conduct extensive experiments across representative multi-modal models, revealing consistent weaknesses and distinctive behaviors. |
|
|
| We find that models struggle to maintain disentangled representations when processing parallel video streams, exhibit interference patterns differing substantially from those observed in human memory, ground memory sources more reliably in the spatial domain than the temporal domain, and demonstrate limited symbolic memory. |
|
|
| Collectively, our benchmark provides a valuable resource for future research, whereas our findings highlight memory as a fundamental yet underexplored capability and offer insights for designing more effective memory mechanisms in multi-modal models. |
|
|
| ## Main Results |
|
|
| ### Divided Attention |
|
|
|  |
|
|
| Accuracy (%) on three divided attention metrics under the split-screen setting without swaps and with frequent left/right swaps. |
|
|
| ### Memory Interference |
|
|
|  |
|
|
| Proactive: first video (V1) interferes with recall of the second video (V2); retroactive: second video (V2) interferes with recall of the first video (V1). Delta denotes proactive minus retroactive. |
|
|
| ### Interleaved Events |
|
|
|  |
|
|
| Accuracy (%) on four interleaved reconstruction metrics. |
|
|
| ### N-Back |
|
|
|  |
|
|
| Average accuracy under two symbolic attributes, scene and action, averaged over all K and N configurations. |
|
|
