يعرض عدم وجود بيانات تدريبية تحديا كبيرا لتحجيم فهم اللغة المنطوقة لغات الموارد المنخفضة.على الرغم من أن نهج تكبير البيانات المختلفة قد اقترحت توليف البيانات التدريبية في لغات مستهدفة منخفضة الموارد، فإن مجموعات البيانات المعززة غالبا ما تكون صاخبة، وبالتالي تعيق أداء نماذج SLU.في هذه الورقة نركز على تخفيف الضوضاء في البيانات المعززة.نقوم بتطوير نهج تدريب Denosising.يتم تدريب نماذج متعددة مع البيانات التي تنتجها الطرق المعززة المختلفة.توفر هذه النماذج إشارات الإشراف لبعضها البعض.تظهر النتائج التجريبية أن أسلوبنا تتفوق على الحالة القائمة من الفن الموجودة بمقدار 3.05 و 4.24 نقطة مئوية عن مجموعات بيانات قياسية على التوالي.سيتم تقديم الرمز مفتوح المصادر على جيثب.
Lack of training data presents a grand challenge to scaling out spoken language understanding (SLU) to low-resource languages. Although various data augmentation approaches have been proposed to synthesize training data in low-resource target languages, the augmented data sets are often noisy, and thus impede the performance of SLU models. In this paper we focus on mitigating noise in augmented data. We develop a denoising training approach. Multiple models are trained with data produced by various augmented methods. Those models provide supervision signals to each other. The experimental results show that our method outperforms the existing state of the art by 3.05 and 4.24 percentage points on two benchmark datasets, respectively. The code will be made open sourced on github.

With counterfactual bandit learning, models can be trained based on positive and negative feedback received for historical predictions, with no labeled data needed. Such feedback is often available in real-world dialog systems, however, the modulariz
Spoken language understanding, usually including intent detection and slot filling, is a core component to build a spoken dialog system. Recent research shows promising results by jointly learning of those two tasks based on the fact that slot fillin
It is now established that modern neural language models can be successfully trained on multiple languages simultaneously without changes to the underlying architecture, providing an easy way to adapt a variety of NLP models to low-resource languages
