The invention discloses a
time sequence sparse and dynamic feedback multi-
modal large model reasoning method, which improves model analysis precision and
processing efficiency through a sparse sampling strategy and a dynamic feedback reasoning mechanism, and effectively solves key challenges in
deep sea geology video analysis. The method comprises the following steps: constructing a structured image-text
data set by integrating multi-source ocean data, and constructing a three-level labeling
system; the method comprises the following steps: based on a multi-
modal large model architecture, performing parameter optimization on a Transform core module by adopting an LoRA technology; a
time sequence sparse sampling and dynamic feedback reasoning mechanism is designed, context frame management is realized through a sliding window and a bidirectional
queue, the calculation complexity is reduced in combination with a sparse sampling strategy, and the
time sequence reasoning consistency is enhanced by using a historical prediction result. Through collaborative innovation of multi-
modal data processing, efficient model optimization and an intelligent reasoning mechanism, synchronous improvement of
deep sea geology analysis precision and efficiency is realized, and a reliable intelligent scheme is provided for marine geology research.
