    The best of AI at Scale: Semantic search capabilities available to Azure customers in preview

    Microsoft Bing partnered with Azure Cognitive Search to make state-of-the-art search AI available to Azure customers through semantic search. Semantic search enables modern search experiences such as semantic ranking, extractive summarization, and machine reading comprehension. These features were built through the application of Microsoft Research technology and advancements—including UniLM, Multi-Task Deep Neural Networks, MiniLM, and utilizing graph attention networks for machine reading comprehension—to search scenarios. Deep neural network transfer learning allows the models to run well in Azure. An online A/B experiment in which semantic search was enabled for Microsoft Docs produced a significant 4.5 percent clickthrough rate increase on challenging queries (three or more words)—the largest relevance improvement the Microsoft Docs team has seen.

    Spell correction at scale

    Customers around the world use Microsoft products in over 100 languages, yet most do not come with high-quality spell correction. This prevents customers from maximizing their ability to search for information on the web and enterprise—and even to author content. With AI at Scale, we used deep learning along with language families to solve this problem for customers by building what we believe is the most comprehensive and accurate spelling correction system ever in terms of language coverage and accuracy.

    DeBERTa: Decoding enhanced BERT with disentangled attention

    Microsoft researchers created DeBERTa (Decoding enhanced BERT with disentangled attention), a Transformer-based neural language model that makes two changes to BERT. It uses disentangled attention for self-attention, with each word represented by two vectors that encode content and position. The attention weights for these words are then computed using their contents and relative positions. DeBERTa also enhances the output layer of BERT for pretraining, by replacing the output softmax layer in BERT with an enhanced masked decoder (EMD) to predict the masked tokens during pretraining.

  18. DeepSpeed team announce ZeRO-2 and optimizations that set the fastest BERT training record at the time

    Figure 2: ZeRO-2 scales to 170 billion parameters, has up to 10x higher throughput, obtains superlinear speedup, and improves usability by avoiding the need for code refactoring for models up to 13 billion parameters.

    Improvements to the DeepSpeed library allow Microsoft researchers to set the fastest BERT training record at the time: 44 minutes on 1,024 NVIDIA GPUs. To do this, they used new technology that used kernel optimizations to boost single GPU performance of models like BERT by more than 30%. These optimizations also allowed for better scaling of large models. In ZeRO-2, memory footprints were reduced in gradients, activation memory, and fragmented memory to improve the scale and speed of deep learning training with DeepSpeed by an order of magnitude.

    Microsoft researchers introduce Oscar for vision and language pretraining

    Oscar object semantics graphic

    Oscar (Object-Semantics Aligned Pretraining) (opens in new tab) arose from the observation that objects can be used as anchor points to make learning semantic alignments between images and texts easier. By coupling images with language in a shared space, Oscar allows objects to act as anchor points in aligning the semantics between images and words. The vision and language pretraining (VLP) framework set state-of-the-art performance on six well-established vision-and-language tasks.

  20. SMART: Using principled regularized optimization for pre-trained natural language model fine-tuning

    In transfer learning, fine-tuning pretrained natural language processing (NLP) models can cause the model to overfit training data of downstream tasks and fail to generalize unseen data. The SMART framework uses smoothness-inducing regularization, in order to manage the complexity of the model, and Bregman proximal point optimization, which can prevent aggressive updating.

  21. Adversarial training for large neural language models

    This work shared a comprehensive study of adversarial training in all stages of training for large neural language models: pretraining from scratch, continual pretraining on a well-trained model, and fine-tuning for specific tasks. The researchers also created a general algorithm to maximize adversarial loss, called ALUM, which obtained substantial gains over BERT on many NLP tasks.

  22. Effects of the adaptive learning rate on stochastic gradient-based optimization

    Microsoft researchers and collaborators looked more closely at how warmup should be conducted in stochastic gradient-based optimization. More specifically, they zeroed in on the variance issue in adaptive learning rate and observe its root cause: limited amount of training samples used cause undesirably large variance in early stages of training. They also presented a new variant of Adam, called RAdam, to correct this problem of variance, and compares well with heuristic warmup.
