. A seed is a tuple ( s = (v, w) ), where ( v \in \mathbbR^d ) is a visual prototype and ( w \in \mathbbR^d ) is a textual prototype, such that for any example ( (x, y) ) from a past task, ( |f_I(x) - v| ) and ( |f_T(y) - w| ) are small, and ( \textsim(v, w) ) is high.

Auto-Seed VL2 maintains a set of auto-generated seeds ( \mathcalS ) that grows slowly over tasks. Auto-Seed VL2 operates in three phases per task: (1) Seed replay, (2) Online adaptation, (3) Seed update. 4.1 Overall Architecture | Configuration | Avg Acc | Drop |

During continual learning, the model is trained sequentially on each task. After learning ( \mathcalT t ), the model should perform well on all seen tasks ( \mathcalT 1:t ) without access to previous data. We allow a small episodic memory ( M ) (size ( K )) that stores generated seeds , not real examples. (2023)

The consistency loss and gradient-conditioned generation are crucial. Seed pruning is memory-efficient without hurting accuracy. We measure FWT: performance on task ( t ) after training on tasks ( 1..t-1 ). Auto-Seed VL2 achieves positive forward transfer (FWT = +4.1%) on VL-CL, meaning seeds from earlier tasks help learn new tasks. ER-VLM shows near-zero FWT; generative replay shows negative transfer due to noisy synthetic images. 7. Analysis and Discussion What do generated seeds encode? We project seeds into CLIP space and compare to real class means. The cosine similarity is 0.89 ± 0.05, indicating faithful representation. However, seeds are more “regularized” – they have lower variance along task-irrelevant directions.
