Doing machine learning the right way – MIT News

The work of MIT computer scientist Aleksander Madry is fueled by one core mission: doing machine learning the right way.

Madrys research centers largely on making machine learning a type of artificial intelligence more accurate, efficient, and robust against errors. In his classroom and beyond, he also worries about questions of ethical computing, as we approach an age where artificial intelligence will have great impact on many sectors of society.

I want society to truly embrace machine learning, says Madry, a recently tenured professor in the Department of Electrical Engineering and Computer Science. To do that, we need to figure out how to train models that people can use safely, reliably, and in a way that they understand.

Interestingly, his work with machine learning dates back only a couple of years, to shortly after he joined MIT in 2015. In that time, his research group has published several critical papers demonstrating that certain models can be easily tricked to produce inaccurate results and showing how to make them more robust.

In the end, he aims to make each models decisions more interpretable by humans, so researchers can peer inside to see where things went awry. At the same time, he wants to enable nonexperts to deploy the improved models in the real world for, say, helping diagnose disease or control driverless cars.

Its not just about trying to crack open the machine-learning black box. I want to open it up, see how it works, and pack it back up, so people can use it without needing to understand whats going on inside, he says.

For the love of algorithms

Madry was born in Wroclaw, Poland, where he attended the University of Wroclaw as an undergraduate in the mid-2000s. While he harbored interest in computer science and physics, I actually never thought Id become a scientist, he says.

An avid video gamer, Madry initially enrolled in the computer science program with intentions of programming his own games. But in joining friends in a few classes in theoretical computer science and, in particular, theory of algorithms, he fell in love with the material. Algorithm theory aims to find efficient optimization procedures for solving computational problems, which requires tackling difficult mathematical questions. I realized I enjoy thinking deeply about something and trying to figure it out, says Madry, who wound up double-majoring in physics and computer science.

When it came to delving deeper into algorithms in graduate school, he went to his first choice: MIT. Here, he worked under both Michel X. Goemans, who was a major figure in applied math and algorithm optimization, and Jonathan A. Kelner, who had just arrived to MIT as a junior faculty working in that field. For his PhD dissertation, Madry developed algorithms that solved a number of longstanding problems in graph algorithms, earning the 2011 George M. Sprowls Doctoral Dissertation Award for the best MIT doctoral thesis in computer science.

After his PhD, Madry spent a year as a postdoc at Microsoft Research New England, before teaching for three years at the Swiss Federal Institute of Technology Lausanne which Madry calls the Swiss version of MIT. But his alma mater kept calling him back: MIT has the thrilling energy I was missing. Its in my DNA.

Getting adversarial

Shortly after joining MIT, Madry found himself swept up in a novel science: machine learning. In particular, he focused on understanding the re-emerging paradigm of deep learning. Thats an artificial-intelligence application that uses multiple computing layers to extract high-level features from raw input such as using pixel-level data to classify images. MITs campus was, at the time, buzzing with new innovations in the domain.

But that begged the question: Was machine learning all hype or solid science? It seemed to work, but no one actually understood how and why, Madry says.

Answering that question set his group on a long journey, running experiment after experiment on deep-learning models to understand the underlying principles. A major milestone in this journey was an influential paper they published in 2018, developing a methodology for making machine-learning models more resistant to adversarial examples. Adversarial examples are slight perturbations to input data that are imperceptible to humans such as changing the color of one pixel in an image but cause a model to make inaccurate predictions. They illuminate a major shortcoming of existing machine-learning tools.

Continuing this line of work, Madrys group showed that the existence of these mysterious adversarial examples may contribute to how machine-learning models make decisions. In particular, models designed to differentiate images of, say, cats and dogs, make decisions based on features that do not align with how humans make classifications. Simply changing these features can make the model consistently misclassify cats as dogs, without changing anything in the image thats really meaningful to humans.

Results indicated some models which may be used to, say, identify abnormalities in medical images or help autonomous cars identify objects in the road arent exactly up to snuff. People often think these models are superhuman, but they didnt actually solve the classification problem we intend them to solve, Madry says. And their complete vulnerability to adversarial examples was a manifestation of that fact. That was an eye-opening finding.

Thats why Madry seeks to make machine-learning models more interpretable to humans. New models hes developed show how much certain pixels in images the system is trained on can influence the systems predictions. Researchers can then tweak the models to focus on pixels clusters more closely correlated with identifiable features such as detecting an animals snout, ears, and tail. In the end, that will help make the models more humanlike or superhumanlike in their decisions. To further this work, Madry and his colleagues recently founded the MIT Center for Deployable Machine Learning, a collaborative research effort within the MIT Quest for Intelligence that is working toward building machine-learning tools ready for real-world deployment.

We want machine learning not just as a toy, but as something you can use in, say, an autonomous car, or health care. Right now, we dont understand enough to have sufficient confidence in it for those critical applications, Madry says.

Shaping education and policy

Madry views artificial intelligence and decision making (AI+D is one of the three new academic units in the Department of Electrical Engineering and Computer Science) as the interface of computing thats going to have the biggest impact on society.

In that regard, he makes sure to expose his students to the human aspect of computing. In part, that means considering consequences of what theyre building. Often, he says, students will be overly ambitious in creating new technologies, but they havent thought through potential ramifications on individuals and society. Building something cool isnt a good enough reason to build something, Madry says. Its about thinking about not if we can build something, but if we should build something.

Madry has also been engaging in conversations about laws and policies to help regulate machine learning. A point of these discussions, he says, is to better understand the costs and benefits of unleashing machine-learning technologies on society.

Sometimes we overestimate the power of machine learning, thinking it will be our salvation. Sometimes we underestimate the cost it may have on society, Madry says. To do machine learning right, theres still a lot still left to figure out.

AI and machine learning is not the future, it’s the present – Eyes on APAC – ComputerWeekly.com

This is a guest post by Raju Vegesna, chief evangelist at Zoho

For many, artificial intelligence (AI) is a distant and incomprehensible concept associated only with science fiction movies or high-tech laboratories.

In reality, however, AI and machine learning is already changing the world we know. From TVs and toothbrushes to real-time digital avatars that interact with humans, the recent CES show demonstrated how widespread AI is becoming in everyday life.

The same can be said of the business community, with the latest Gartner research revealing that 37% of organisations had implemented some form of AI or machine learning.

So far, these technologies have largely been adopted and implemented more by larger organisations with the resources and expertise to seamlessly integrate them into their business. But technology has evolved significantly in recent years, and SaaS (software as a service) providers now offer integrated technology and AI that meets the needs and budgets of small and medium businesses too.

Here are a few evolving trends in AI and machine learning that businesses of all sizes could capitalise on in 2020 and beyond.

The enterprise software marketplace is expanding rapidly. More vendors are entering the market, often with a growing range of solutions, which creates confusion for early adopters of the technology. Integrating new technologies from a range of different vendors can be challenging, even for large enterprise organisations.

So, in 2020 and beyond, the businesses that will make the most of AI and machine learning are the ones implementing single-vendor technology platforms. Its a challenge to work with data that is scattered across different applications using different data models, but organisations that consolidate all its data in one integrated platform will find it much easier to feed it into a machine learning algorithm.

After all, the more data thats available, the more powerful your AI and machine learning models will be. By capitalising on the wealth of data supplied by integrated software platforms, advanced business applications will be able to answer our questions or help us navigate interfaces. If youre a business owner, planning to utilise AI and machine learning for your business in 2020, then the single-vendor strategy is the way to go.

Technology has advanced at such a rate that businesses no longer need to compromise to fit the technology. This type of hyper-personalisation increases productivity for business software users and will continue to be a prime focus for businesses in 2020.

Take, for example, the rise of algorithmic social media timelines we have seen in the last few years. For marketers, AI and machine learning mean personalisation is becoming more and more sophisticated, allowing businesses to supercharge and sharpen their focus on their customers. Companies which capture insights to create personalised customer experiences and accelerate sales will likely win in 2020.

With AI and machine learning, vast amounts of data is processed every second of the day. In 2020, one of the significant challenges faced by companies implementing AI and machine learning is data cleansing the process of detecting, correcting or removing corrupt or inaccurate records from a data set.

Smaller organisations can begin to expect AI functionality in everyday software like spreadsheets, where theyll be able to parse information out of addresses or clean up inconsistencies. Larger organisations, meanwhile, will benefit from AI that ensures their data is more consumable for analytics or prepares it for migration from one application to another.

Businesses can thrive with the right content and strategic, innovative marketing. Consider auto-tagging, which could soon become the norm. Smartphones can recognise and tag objects in your photos, making your photo library much more searchable. Well start to see business applications auto-tag information to make it much more accessible.

Thanks to AI, customer relationship management (CRM) systems will continue to be a fantastic and always-advancing channel through which businesses can market to their customers. Today, businesses can find its top customers in a CRM system by running a report and sorting by revenue or sales. In the coming years, businesses will be able to search top customers, and its CRM system will know what theyre looking for.

With changing industry trends and demands, its important for all businesses to use the latest technology to create a positive impact on its operations. In 2020 and beyond, AI and machine learning will support businesses by helping them reduce manual labour and enhance productivity.

While some businesses, particularly small businesses, might be apprehensive about AI, it is a transformation that is bound to bring along a paradigm shift for those that are ready to take a big step towards a technology-driven future.

Navigating the New Landscape of AI Platforms – Harvard Business Review

Executive Summary

What only insiders generally know is that data scientists, once hired, spend more time building and maintaining the tooling for AI systems than they do building the AI systems themselves. Now, though, new tools are emerging to ease the entry into this era of technological innovation. Unified platforms that bring the work of collecting, labelling, and feeding data into supervised learning models, or that help build the models themselves, promise to standardize workflows in the way that Salesforce and Hubspot have for managing customer relationships. Some of these platforms automate complex tasks using integrated machine-learning algorithms, making the work easier still. This frees up data scientists to spend time building the actual structures they were hired to create, and puts AI within reach of even small- and medium-sized companies.

Nearly two years ago, Seattle Sport Sciences, a company that provides data to soccer club executives, coaches, trainers and players to improve training, made a hard turn into AI. It began developing a system that tracks ball physics and player movements from video feeds. To build it, the company needed to label millions of video frames to teach computer algorithms what to look for. It started out by hiring a small team to sit in front of computer screens, identifying players and balls on each frame. But it quickly realized that it needed a software platform in order to scale. Soon, its expensive data science team was spending most of its time building a platform to handle massive amounts of data.

These are heady days when every CEO can see or at least sense opportunities for machine-learning systems to transform their business. Nearly every company has processes suited for machine learning, which is really just a way of teaching computers to recognize patterns and make decisions based on those patterns, often faster and more accurately than humans. Is that a dog on the road in front of me? Apply the brakes. Is that a tumor on that X-ray? Alert the doctor. Is that a weed in the field? Spray it with herbicide.

What only insiders generally know is that data scientists, once hired, spend more time building and maintaining the tools for AI systems than they do building the systems themselves. A recent survey of 500 companies by the firm Algorithmia found that expensive teams spend less than a quarter of their time training and iterating machine-learning models, which is their primary job function.

Now, though, new tools are emerging to ease the entry into this era of technological innovation. Unified platforms that bring the work of collecting, labelling and feeding data into supervised learning models, or that help build the models themselves, promise to standardize workflows in the way that Salesforce and Hubspot have for managing customer relationships. Some of these platforms automate complex tasks using integrated machine-learning algorithms, making the work easier still. This frees up data scientists to spend time building the actual structures they were hired to create, and puts AI within reach of even small- and medium-sized companies, like Seattle Sports Science.

Frustrated that its data science team was spinning its wheels, Seattle Sports Sciences AI architect John Milton finally found a commercial solution that did the job. I wish I had realized that we needed those tools, said Milton. He hadnt factored the infrastructure into their original budget and having to go back to senior management and ask for it wasnt a pleasant experience for anyone.

The AI giants, Google, Amazon, Microsoft and Apple, among others, have steadily released tools to the public, many of them free, including vast libraries of code that engineers can compile into deep-learning models. Facebooks powerful object-recognition tool, Detectron, has become one of the most widely adopted open-source projects since its release in 2018. But using those tools can still be a challenge, because they dont necessarily work together. This means data science teams have to build connections between each tool to get them to do the job a company needs.

The newest leap on the horizon addresses this pain point. New platforms are now allowing engineers to plug in components without worrying about the connections.

For example, Determined AI and Paperspace sell platforms for managing the machine-learning workflow. Determined AIs platform includes automated elements to help data scientists find the best architecture for neural networks, while Paperspace comes with access to dedicated GPUs in the cloud.

If companies dont have access to a unified platform, theyre saying, Heres this open source thing that does hyperparameter tuning. Heres this other thing that does distributed training, and they are literally gluing them all together, said Evan Sparks, cofounder of Determined AI. The way theyre doing it is really with duct tape.

Labelbox is a training data platform, or TDP, for managing the labeling of data so that data science teams can work efficiently with annotation teams across the globe. (The author of this article is the companys co-founder.) It gives companies the ability to track their data, spot, and fix bias in the data and optimize the quality of their training data before feeding it into their machine-learning models.

Its the solution that Seattle Sports Sciences uses. John Deere uses the platform to label images of individual plants, so that smart tractors can spot weeds and deliver pesticide precisely, saving money and sparing the environment unnecessary chemicals.

Meanwhile, companies no longer need to hire experienced researchers to write machine-learning algorithms, the steam engines of today. They can find them for free or license them from companies who have solved similar problems before.

Algorithmia, which helps companies deploy, serve and scale their machine-learning models, operates an algorithm marketplace so data science teams dont duplicate other peoples effort by building their own. Users can search through the 7,000 different algorithms on the companys platform and license one or upload their own.

Companies can even buy complete off-the-shelf deep learning models ready for implementation.

Fritz.ai, for example, offers a number of pre-trained models that can detect objects in videos or transfer artwork styles from one image to another all of which run locally on mobile devices. The companys premium services include creating custom models and more automation features for managing and tweaking models.

And while companies can use a TDP to label training data, they can also find pre-labeled datasets, many for free, that are general enough to solve many problems.

Soon, companies will even offer machine-learning as a service: Customers will simply upload data and an objective and be able to access a trained model through an API.

In the late 18th century, Maudslays lathe led to standardized screw threads and, in turn, to interchangeable parts, which spread the industrial revolution far and wide. Machine-learning tools will do the same for AI, and, as a result of these advances, companies are able to implement machine-learning with fewer data scientists and less senior data science teams. Thats important given the looming machine-learning, human resources crunch: According to a 2019 Dun & Bradstreet report, 40 percent of respondents from Forbes Global 2000 organizations say they are adding more AI-related jobs. And the number of AI-related job listings on the recruitment portal Indeed.com jumped 29 percent from May 2018 to May 2019. Most of that demand is for supervised-learning engineers.

But C-suite executives need to understand the need for those tools and budget accordingly. Just as Seattle Sports Sciences learned, its better to familiarize yourself with the full machine-learning workflow and identify necessary tooling before embarking on a project.

That tooling can be expensive, whether the decision is to build or to buy. As is often the case with key business infrastructure, there are hidden costs to building. Buying a solution might look more expensive up front, but it is often cheaper in the long run.

Once youve identified the necessary infrastructure, survey the market to see what solutions are out there and build the cost of that infrastructure into your budget. Dont fall for a hard sell. The industry is young, both in terms of the time that its been around and the age of its entrepreneurs. The ones who are in it out of passion are idealistic and mission driven. They believe they are democratizing an incredibly powerful new technology.

The AI tooling industry is facing more than enough demand. If you sense someone is chasing dollars, be wary. The serious players are eager to share their knowledge and help guide business leaders toward success. Successes benefit everyone.
