TinyMem: Condensing Multimodal Memory for Long-Form Video Action Detection
Summary
TinyMem introduces compact multimodal memory for long-form video action detection. This approach significantly improves performance by condensing video content, outperforming state-of-the-art models with fewer memory tokens.
Area of Science:
- Computer Science
- Artificial Intelligence
- Machine Learning
Background:
- Deep neural networks advance video understanding but struggle with long videos.
- Current methods use dense visual embeddings in memory caches for spatio-temporal dependencies.
- Existing approaches with extensive memory tokens show limited performance gains.
Purpose of the Study:
- To improve long-form video action detection using compact memory representations.
- To introduce TinyMem, a novel model leveraging compact multimodal memory.
- To explore the effectiveness of condensed yet informative memory for video analysis.
Main Methods:
- Developed TinyMem, a model utilizing compact multimodal memory.
- Condensed redundant video content into succinct descriptions for textual semantics.
- Integrated region-condensed visual embeddings with text embeddings.
Main Results:
- TinyMem significantly outperforms state-of-the-art models on benchmark datasets (AVA v2.2, Epic-Kitchens-100, Breakfast).
- Achieved 37.4 mAP on AVA v2.2 using TinyMem-24-12 with highly condensed memory.
- Utilized 5 times fewer memory tokens compared to baselines with dense visual embeddings.
Conclusions:
- Compact multimodal memory representations are effective for long-form video action detection.
- TinyMem offers a more efficient approach to modeling long-range spatio-temporal dependencies.
- The findings suggest a promising direction for enhancing video understanding models.

01:06Fixed Action Patterns
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
01:18Long-Term Memory
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

01:22Chunking and Rehearsal in Sensory Memory
Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of information more...
