Building real-world conversational AI applications requires resource-efficient models that can learn in low-data regimes with only a handful of annotated examples. Fully fine-tuning large pretrained language models is expensive and computationally intractable for these applications, where fast-paced development cycles are necessary. This talk presents ConveRT and ConVEx; effective, affordable, quick-to-train, and quick-to-fine-tune sentence encoders that work well in such few-shot low-data scenarios. These encoders achieve state-of-the-art performance across a wide range of conversational tasks such as response selection, intent classification and value extraction, offering quick and effective adaptation to new tasks, domains, and languages.
