Extracting Multimodal Learngene in CLIP: Unveiling the Multimodal Generalizable Knowledge

AAAI 2026technical

CLIP (Contrastive Language-Image Pre-training) has attracted widespread attention for its multimodal generalizable knowledge, which is significant for downstream tasks. However, the computational overhead of a large number of parameters and large-scale pre-training poses challenges of pre-training a

Unlocking Pre-trained Weights: Parameter Inheritance for Zero-Shot Initialization

CVPR 2026

Appropriate parameter initialization is crucial for reducing the training cost of deep neural networks. Graph HyperNetworks (GHN) have emerged as a promising approach for initializing diverse architectures, with recent methods such as Task-Aware Learngene (TAL) further attempting to leverage pre-tra

When Labelers Stay Silent: The Power of Ties in Cost-Effective Preference Learning

ICML 2026poster

Standard preference alignment relies on a binary forced-choice paradigm, assuming definitive preferences for all pairs. However, we find that indistinguishable pairs are prevalent even in standard benchmarks, where quality differences of two responses often fall below the labeler's discriminative re…

Transformer as Linear Expansion of Learngene

AAAI 2024technical

We propose expanding the shared Transformer module to produce and initialize Transformers of varying depths, enabling adaptation to diverse resource constraints. Drawing an analogy to genetic expansibility, we term such module as learngene. To identify the expansion mechanism, we delve into the rela…

What Makes Partial-Label Learning Algorithms Effective?

NeurIPS 2024poster

A partial label (PL) specifies a set of candidate labels for an instance and partial-label learning (PLL) trains multi-class classifiers with PLs. Recently, many methods that incorporate techniques from other domains have shown strong potential. The expectation that stronger techniques would enhance…

Towards Effective Visual Representations for Partial-Label Learning

CVPR 2023poster

Under partial-label learning (PLL) where, for each training instance, only a set of ambiguous candidate labels containing the unknown true label is accessible, contrastive learning has recently boosted the performance of PLL on vision tasks, attributed to representations learned by contrasting the s…
