Researchers have introduced AlphaWiSE, a novel method for continual multimodal representation learning. This post-hoc weight-space interpolation technique combines two frozen source checkpoints by fitting a single scalar interpolation coefficient for each aligned parameter tensor. AlphaWiSE materializes an interpolated checkpoint using this coefficient, which is fitted on a small exemplar memory. The resulting model maintains the same architecture and parameter count as the original checkpoints, requiring no additional inference time and demonstrating consistent improvements over existing continual-learning baselines in audio-image-text retrieval tasks.
