Understanding the Role of Momentum in Stochastic Gradient Methods

Neural Information Processing Systems

Different variants ofmomentum, including heavyball momentum, Nesterov's accelerated gradient (NAG), and quasi-hyperbolic momentum (QHM), havedemonstrated success onvarious tasks. Our results are most closely related to the work of Mandt et al.[19]who use stationaryanalysis of SGD with momentum to perform approximateBayesianinference.

Neural Information Processing Systems

We perform finetuning with image-textcontrastiveand image-textmatching losses. During inference, VLMO is first used as a dual encoder to obtain top-k candidates, then the model is used as a fusionencoder torerankthecandidates. For the text-only pre-training data, we use English Wikipedia and BookCorpus [5]. Table 1: Ablation study of the shared self-attention module used in Multiway Transformer.
