Research at Microsoft 2021: Collaborating for real-world change
Over the past 30 years, Microsoft Research has undergone a shift in how it approaches innovation, broadening its mission to include not only advancing the state of computing but also using technology to tackle some of the world’s most pressing challenges. That evolution has never been more prominent than it was during this past year.
Recent events underscore the urgent need to address planet-scale problems. Fundamental advancements in science and technology have a crucial role to play in addressing ongoing societal challenges such as climate change, healthcare equity and access, supply chain logistics, sustainability, security and privacy, and the digital divide. Microsoft Research is increasing focus on these areas and others to help accelerate transformational change and build trust in technology as it evolves. However, these challenges are too large for any single organization to meet alone. They require broader and more diverse coalitions across the global science and technology community, including businesses, scholars, governments, nongovernmental organizations, and local communities.
This year, Microsoft Research hosted the first-ever Microsoft Research Summit, a virtual event that embodied our aspiration to catalyze collaboration and innovation across traditional boundaries. The summit brought together experts from around the world—a mix of speakers from Microsoft and external organizations—to critically examine the way technology can increase understanding and further drive advancement; support creativity and achievement; build a resilient, sustainable society; and open healthcare advances to all while maintaining ethical practices that put people first.
This post explores just some of the work that’s been done this year by Microsoft Research, alongside its partners and collaborators, to drive real-world impact in critical areas, and our aspirations for further impact in the years to come.
Leading the way for real-world impact
Advancing human knowledge and foundational technologies
Fundamental insights into technology and computing can inspire breakthroughs and new computing paradigms while helping to drive scientific discovery forward. In his plenary talk at Research Summit, Peter Lee, Corporate Vice President, Microsoft Research & Incubations, cited “The Usefulness of Useless Knowledge,” an essay published in Harper’s Magazine in 1939 by pioneering educator Abraham Flexner. Among other things, the essay stresses the role that curiosity and exploration play in game-changing technological leaps. It’s at this root of invention and innovation, Flexner argues, where patience and belief in shared knowledge is key.
LAMBDA, one of this year’s first big announcements, shows how the Microsoft research community can make significant contributions to products and customers when given the time and freedom to follow their curiosities. In this case, the product was Microsoft Excel—a program that has benefitted from the efforts of research teams over time. The feature, which resulted from collaboration between members of the Calc Intelligence and Excel teams, gives users the ability to define custom worksheet functions in Excel’s formula language, making the program Turing-complete, that is, allowing any computation to be written in the Excel formula language.
To make networks in data centers more scalable to future needs, researchers in Optics for the Cloud explored how optical circuit switches could replace resource-heavy electrical switches at a network’s core. They demonstrated the system’s potential to switch between wavelengths at nanosecond speeds—a necessity for supporting low-latency networks at the scale required—using a microcomb and semiconductor optical amplifiers.
A research team moved the bar forward for DNA storage, introducing a proof-of-concept molecular controller in the form of a tiny DNA storage writing mechanism on a chip. The chip demonstrated the ability to pack DNA-synthesis spots three orders of magnitude more tightly than before and results in much higher DNA writing throughput than current systems.
AI at Scale continued to gain momentum in 2021. With exponential growth this year, large artificial intelligence (AI) models trained using deep learning are one example of fundamental science where applications in the real world are becoming more ubiquitous. Microsoft Research teams were recognized for advancing the state of the art and developing new multilingual capabilities to build more inclusive language technologies using AI as well as pushing the boundaries of natural language processing (NLP) and computer vision.
In June 2021, Microsoft Research’s LReasoner system set a new standard for logical reasoning ability among pretrained language models. It reached the top of the official leaderboard for ReCLor, a dataset built using questions from the LSAT and GMAT, two standardized admissions tests.
Microsoft Turing’s T-ULRv5 achieved breakthrough performance on the XTREME leaderboard in September. A few weeks later, Microsoft Turing’s model T-NLRv5 reached the top of the SuperGLUE and GLUE leaderboards. Ultimately, these benchmarks and respective leaderboards help to measure progress toward creating AI that better understands language and better converses with people within and across language boundaries. To understand how quickly these advances are happening, one need only look to Megatron-Turing NLG, the language generation model with 530 billion parameters trained to convergence—a collaboration between Microsoft and NVIDIA.
To train the Megatron-Turing model, DeepSpeed and NVIDIA Megatron-LM paired up to create an efficient and scalable 3D-parallel system harnessing data parallelism, pipeline parallelism, and tensor slicing–based parallelism. Beyond this achievement, the DeepSpeed optimization library added a number of features and tools this year, including DeepSpeed Inference, its first foray into improving inference latency and cost using multiple graphic processing units (GPUs). The team also introduced DeepSpeed MoE, supporting five types of parallelism and training 8x larger models when compared with existing systems. Zero-Infinity allowed for scaling of large model training from one to thousands of GPUs, furthering its effort to democratize model training for everyone.
These large AI models are impressive in their own right, but it’s what they’re able to do to support people and democratize innovation that makes them especially valuable. Advances in language technologies resulted in the expansion of Microsoft translation and spelling-correction technologies into over 100 languages, breaking down language barriers in products like Microsoft Bing and Microsoft Translator. The Microsoft Turing Team also introduced Turing Bletchley, a 2.5 billion-parameter Universal Image Language Representation model (T-UILR) that can perform image-language tasks in 94 languages.
Meanwhile, researchers from Microsoft Research Asia worked on bridging the gap between computer-language and computer-vision modeling. In October, members of the Visual Computing group won the Conference on Computer Vision (ICCV) 2021 award for their paper on the Swin Transformer. This vision transformer surpasses the state of the art with its high performance, flexibility, and linear complexity, making it compatible with a broad range of vision tasks. With this work, the research team hopes to inspire additional research in this area that will ultimately enable joint modeling between the computer vision and language domains. Research teams in the same lab examined the potential for transformers to find success beyond language and vision, demonstrating the neural network architecture can be applied to graph representation learning. With their standard transformer architecture Graphormer, the researchers achieved state-of-the-art performance in the KDD Cup 2021 graph-level prediction track and topped popular graph-level prediction leaderboards.
Amplifying human creativity and achievement
People are multidimensional, pursuing goals and tasks across different areas of their lives, under a variety of circumstances. Microsoft researchers are dedicated to not only helping individuals accomplish more in their personal, professional, and creative lives, but also to helping them feel more confident doing so.
Over the past year and a half, researchers and product teams throughout Microsoft have responded swiftly to workplace challenges and opportunities arising from the pandemic. Supporting organizations in executing hybrid work models, they explored technology as an intermediary between people who are physically in the room and those who are not, with some researchers presenting their findings in a hybrid meeting prototype during Research Summit. Researchers investigated remote and hybrid work from a variety of angles—from longitudinal studies on multitasking behavior to workplace communication insights gleaned using network machine learning—to understand where technology needs to grow to help people thrive under these fluid working conditions. Previous and ongoing work in this area is captured by the New Future of Work Initiative and the annual Work Trend Index.
As ML techniques and approaches advance, so does the potential for applications to empower individuals in the workplace and beyond does, too. Research teams are leveraging few-shot learning to help support AI that is truly more customizable to the individual with the ORBIT dataset and benchmark. The dataset and benchmark are inspired by a real-world application for people who are blind or have low vision called teachable object recognizers. The dataset strives to reflect the variance within object types and input quality that recognition systems will encounter in the day-to-day, while the benchmark challenges models to identify objects for single users from a few, high-variation examples.
Earlier in the year, at the CHI 2021 Conference on Human Factors in Computing Systems, researchers presented tools and learnings guided by a changing definition of accessibility, one that focuses on helping individuals rise above limitations imposed by a world built to accommodate the majority to realize their full capabilities. Also, members of the Enable Group explored the continuing evolution of Soundscape, an app that uses 3D spatial audio to elevate users’ perception of an environment they’re navigating.
Environmental sustainability is a key focus area for Microsoft Research. We support our customers’ efforts to reduce carbon emissions, including our work with Project Zerix, which combines biotechnology, chemistry, and materials science with computer science and engineering to develop more environmentally sustainable materials for the IT industry.
Project Eclipse is an example of local collaboration toward building sustainable and resilient cities. It’s the largest real-time, hyperlocal air-quality sensing network in a North American city. The Urban Innovation team worked with local partners in Chicago to deploy over 100 low-cost air pollution sensors across the city. The team provided several updates this year, including a new video showing how the system works, plus a demo and related presentation at Research Summit.
Supporting a healthy global society
Technology is driving amazing progress in human health, exemplified by the unprecedented development of testing, vaccines, and treatments for COVID-19. It’s important to make those treatments and therapies available as broadly as possible. Microsoft Research supports inclusive and equitable technologies and studies that improve scientific discovery, along with better, more equitable delivery of health care of people everywhere.
In 2021, as the pandemic raged, it hit some populations harder than others, including people with limited access to or experience with technology. To lower barriers to health information, Microsoft Research developed the Covid-19 Vaccine Eligibility Bot to help people understand their eligibility to receive COVID vaccinations. The bot is accessible across a range of communication channels and in local languages to serve non-English speakers. Separately, a new partnership including Broad Institute of MIT and Harvard, Verily, and Microsoft will provide cloud, data and AI technology, and access to its global network of more than 168,000 health and life science partners, to help researchers interpret an unprecedented amount of biomedical data to advance the treatment of human diseases through the open-source platform Terra.
As with any health-related technology, it’s important that new medical AI applications adhere to privacy regulations that safeguard sensitive data. Microsoft Research India developed a framework for secure, privacy-preserving, and AI-enabled medical imaging inference using CrypTFlow2, a state-of-the-art end-to-end compiler allowing cryptographically secure two-party computation (2PC) protocols. CrypTFlow2 may allow developers without cryptography experience to build efficient and scalable multi-party computation (MPC) protocols for inference tasks, dramatically improving health providers’ ability to process and analyze sensitive data while respecting privacy.
Deep learning and open-source strategies can improve cancer radiotherapy workflows and care. But the learning models are not easily accessible to researchers and care providers. This webinar provides an update on Project InnerEye, which aims to democratize AI for medical image analysis and empower health professionals to build medical imaging AI models.
Microsoft Research continued to research and develop new technologies to improve healthcare and access for all. Two examples from 2021 include:
Ensuring that technology is trustworthy and beneficial to everyone
Fully realizing the value of technology requires the trust of those it’s intended to help. And trust is earned, which is why developing AI responsibly is a key tenet of the Microsoft mission. Researchers at the company are guided by the principles of fairness, reliability and safety, inclusiveness, and transparency, among others, in their pursuit of advancement, and they build and share resources and tools to incorporate those principles into research and development. Those tools include the Responsible AI (RAI) Toolbox and the Human AI eXperience (HAX) Toolkit. Combining error analysis, model interpretability, fairness, counterfactual example analysis, and causal analysis tools, the RAI Toolbox provides practitioners with the means to understand model behavior, identify and address issues, and support real-world decision-making, while HAX provides actionable resources for prioritizing the safety and needs of people throughout the development of human-AI experiences.
Understanding the benefits and harms of language models has been of particular interest to the broader research community. In discussing the topic at Research Summit, researchers explored limitations of current task framing in building tech that meets real needs and called for interdisciplinary methods to more effectively study real-world impact. Microsoft researchers also covered a variety of other topics related to cultivating trust in AI systems, including executing responsible AI and identifying, assessing, and mitigating harms in AI systems, as part of the Microsoft Research Webinar series. Microsoft Research also launched a monthly lecture series examining the relationship between technology and the perception of race and its ramifications (for more information, see the section below).
New complexity in AI systems and an increased reliance on using data to develop and train those systems brings with it increased requirements for keeping those systems secure. This year, researchers at Microsoft started the Privacy Preserving Machine Learning (PPML) initiative to address the need for preserving individual data privacy throughout the ML pipeline. Differential privacy (DP) is one technique that plays an important role in this initiative. Microsoft Research is pushing the boundaries in DP research with the overarching goal of providing Microsoft customers with the best possible productivity experiences through improved ML models for NLP while providing highly robust privacy protections.
Cryptography and privacy researchers are committed to protecting the confidentiality of people’s data, and in January, they collaborated with the Microsoft Edge product team to introduce Password Monitor for Microsoft Edge, a security feature that notifies users if any of their saved passwords has been found in a third-party breach. The underlying technology uses homomorphic encryption, a technique pioneered at Microsoft Research, which ensures the privacy and security of users’ passwords.
Watch For, a technology incubated in Microsoft Research, has been helping to create safe and inclusive digital spaces for Xbox and other platforms. The real-time media content analytics platform traces its beginnings back to the 2017 internal hackathon hosted by Microsoft and has garnered attention as the engine behind HypeZone, gaming’s version of NFL RedZone. Watch For is now officially a part of Xbox Family, Trust, and Safety and will continue to help support content moderation and online safety throughout Microsoft.
Engaging with the broader research community and looking to the future
Microsoft Research values its ties to the academic community, and it continued to support research and learning through its fellowship and grant opportunities in 2021.
To confront challenges through research and technology, we’re sometimes required to engage in new ways. This year, Microsoft Research started the Race and Technology lecture series, a virtual speaker series designed to foster understanding of, and inspire continued research into, how the perception of race influences technology and vice versa through the work of distinguished academics and domain experts. This series continues through June 2022.
