Web2 days ago · Intuitively, the class label itself has the intrinsic ability to perform hard positive/negative mining, which is crucial for CL. Motivated by this, we propose a novel … WebIn this work, we propose a novel multi-modal SLU method, named CMCL, which utilizes cross-modal contrastive learning to learn better multi-modal representation. In particular, a two-stream multi-modal framework is designed, and a contrastive learning task is performed across speech and text representations.

Web3 May 2024 · Brief introduction. Contrastive learning is a machine learning technique used to learn the general features of a dataset without labels by teaching the model which data points are similar or different.. The idea is intuitive, given 3 pictures above; 2 cats and 1 dog. The goal of contrastive learning is to discriminate the cats from the dog by comparing the … WebTo learn more discriminative feature representations, we further propose a novel neighbor-guided category-level contrastive learning term to minimize the intra-class distance and enlarge the inter-class distance. We conduct extensive experiments on four datasets to validate the effectiveness. Compared with the state-of-the-art methods, our ...
