“The next AI generation will be the big revolution. We haven’t seen anything yet.”

FCAI Professor Petri Myllymäki gave a talk at a conference on innovation in the EU in Brussels organized by Science|Business.

Even though public bodies and large companies are investing heavily on AI technology and development, Myllymäki noted in the conference, according to a story by Science|Business that the current AIs are stil, in fact, in their infancy. Existing AI methods are good with big data sets that are properly annotated, but they are still “black-boxed”: there is little or no way of knowing how the AI came up with a solution it did, or, what happens between the input and the output.

Myllymäki said that ‘[current AIs] work in some narrow environments remarkably well, if you have a lot of data. They have been productised and there are nice tools you can use, so these are the primary reasons for the current AI revolution.’

‘The next generation will be the big revolution. We haven’t seen anything yet.’

What we haven’t seen is Real AI. Making Real AI a reality is very much at the core of what FCAI strives to do: to create AI tools that are transparent, able to explain themselves to the user, use scarce resources efficiently and take not of user privacy and security in all steps.

New metagenomics tool mSWEEP accurately characterises mixed bacterial colonies

Determining the composition of bacterial communities at strain level resolution is critical for many applications in infectious disease epidemiology and in bacterial ecology.

Using the latest advances in computational inference and sequence analysis, an international team involving close collaboration with leading institutions on bacterial genomics, including the Wellcome Sanger Institute and University of Oxford, led by professors Jukka Corander and Antti Honkela (both in FCAI) has developed a new metagenomics tool called mSWEEP, which goes significantly beyond the state of the art in this field.

The effectiveness of mSWEEP is demonstrated with infection data from major human pathogens and it is expected to pave the way for entirely new approaches to addressing important biological and clinical questions about inter-strain competition, dissemination of resistance and virulence.

Espoo becomes a member of FCAI: researchers to develop artificial intelligence for the services of the city

The City of Espoo has become a member of the Finnish Center for Artificial Intelligence FCAI. FCAI is a research centre launched by Aalto University and University of Helsinki, which gathers together the best artificial intelligence researchers in Finland. FCAI's objective is to make the most advanced methods of artificial intelligence available to enterprises, organisations and society.

The City of Espoo sees that developing artificial intelligence together will be beneficial for the whole innovation community from enterprises to R&D organisations and the inhabitants in Espoo.

“For a researcher, the data in the databases of the city of Espoo and the shared databases of the Helsinki metropolitan area is very interesting. Especially the innovative start-up companies in the area and Espoo's desire to be profiled as a pioneer in the use of intelligent technologies set a good basis for cooperation with researchers developing artificial intelligence. We have all the prerequisites to expand our cooperation to other research centres and other cities as well,” says the Head of FCAI, Academy Professor Samuel Kaski.

“On the one hand, researchers need data for the development of artificial intelligence methods and technology, and public organisations have this data. On the other hand, we as a city get to use the methods, technologies and the latest knowledge of artificial intelligence research in the development of our services,” says Tomas Lehtinen, data analyst consultant for the City of Espoo.

Restoring images without clean data

There are several real-world situations where obtaining clean training data is difficult. For instance, low-light photography – astronomical imaging, for example – physically-based image synhesis and magnetic resonance imaging are such cases.

Aalto University and FCAI professor Jaakko Lehtinen with his team from NVIDIA and MIT postdoctoral researcher Miika Aittala show in their paper accepted to the International Conference on Machine Learning ICML 2018 that it is possible to recover signals under complex corruptions without observing clean signals, at performance levels equal or close to using clean target data.

They have applied basic statistical reasoning to signal reconstruction by machine learning — learning to map corrupted observations to clean signals — with a simple and powerful conclusion: under certain common circumstances, it is possible to learn to restore signals without ever observing clean ones, at performance close or equal to training using clean exemplars.

The team applies their methods to photographic noise removal, denoising of synthetic Monte Carlo images, and reconstruction of MRI scans from under-sampled inputs. All cases are based on only observing corrupted data.

Blurred lines between search and recommendation: interactive data exploration

Recent work by FCAI researchers Tuukka Ruotsalo, Tung Vuong, Khalil Klouche, Salvatore Andolina and Giulio Jacucci investigate the role of interactive machine learning in exploring data. Their particular emphasis is on efficient user input and transparency of recommendation – the ‘how’ and ‘why’ of search queries, respectively.

In one case, users explore points of interests using available social content and review data from Yelp Phoenix, Arizon (11,000 PoI; 225,000 reviews; 42,000 users): personal preferences, tags combined with personal preferences, and tags and social ratings combined with personal preferences. The transparency (provenance) of recommendation was decisive as the combination of social rating information and personal preference information improves search effectiveness and reduce the need to consult external information.

In other research in exploring the entire data set of scientific publications over 50 million papers, the FCAI team have been able to show – using similar graph-based machine learning – how to support efficient user input in exploration by allowing users to easily interact with entities such as people, keywords and documents.

The research is a prime example of interactive AI and has important implications for developing system that aid exploration of products, documents, points of interest or people. The examples showcase how online machine learning can make use of user input for interactive AI.

A new paradigm of ordinary differential equations

Aalto University and FCAI professor Harri Lähdesmäki has with his colleagues introduced a new paradigm of non-parametric ordinary differential equations modeling that can learn the underlying dynamics of arbitrary continuous-time systems without prior knowledge.

For many complex systems it is practically impossible to determine equations or interactions that would govern the underlying dynamics. In these settings, a parametric ODE model cannot be formulated. Lähdesmäki and his team have now overcome this issue. They propose to learn non-linear, unknown differential functions from state observations using Gaussian process vector fields within the exact ODE formalism.

They demonstrate the model’s capabilities to infer dynamics from sparse data and to simulate the system forward into future.

See article by Markus Heinonen, Cagatay Yildiz, Henrik Mannerström, Jukka Intosalmi, Harri Lähdesmäki, ‘Learning unknown ODE models with Gaussian processes’:

The paper has been accepted to the International Conference on Machine Learning ICML 2018.


Making efficient use of sensitive big data and keep it safe and private?

A new method developed by FCAI researchers of University of Helsinki and Aalto University together with Waseda University of Tokyo can use, for example, data distributed on cell phones while guaranteeing data subject privacy.

Modern AI is based on learning from data, and in many applications using data of health and behaviour the data are private and need protection.

Machine learning needs security and privacy: both the data used for learning and the resulting model can leak sensitive information.

Machine learning needs security and privacy: both the data used for learning and the resulting model can leak sensitive information.

Based on the concept of differential privacy, the method guarantees that the published model or result can reveal only limited information on each data subject while avoiding the risks inherent in centralised data.

In the new method, using distributed data avoids the risks of centralized data processing, and the model is learned under strict privacy protection.

In the new method, using distributed data avoids the risks of centralized data processing, and the model is learned under strict privacy protection.

Privacy-aware machine learning is one key in tackling data scarcity and dependability, both identified by FCAI as major bottlenecks for wider adoption of AI. Strong privacy protection encourages people to trust their data with machine learners without having to worry about negative consequences as a result of their participation.

The method was published and presented in December in the annual premiere machine learning conference NIPS: https://papers.nips.cc/paper/6915-differentially-private-bayesian-learning-on-distributed-data.

FCAI researchers involved in the work: Mikko Heikkilä, Eemil Lagerspetz, Sasu Tarkoma, Samuel Kaski, and Antti Honkela.


Yes, but did it work? Evaluating Variational Inference

While it’s always possible to compute a variational approximation to a posterior distribution, it can be difficult to discover problems with this approximation. Aalto University and FCAI professor Aki Vehtari proposes with his colleagues two diagnostic algorithms to alleviate this problem.

The Pareto-smoothed importance sampling (PSIS) diagnostic gives a goodness of fit measurement for joint distributions, while simultaneously improving the error in the estimate. The variational simulation-based calibration (VSBC) assesses the average performance of point estimates.

The paper by Yuling Yao, Aki Vehtari, Daniel Simpson, and Andrew Gelman, ‘Yes, but Did It Work?: Evaluating Variational Inference’ has been accepted to the International Conference on Machine Learning ICML 2018.

AI-created family trees confirm class divisions in Finland in the 18th and 19th century

The genealogy algorithm AncestryAI efficiently combines huge amounts of birth data.
It would take 100 person-years for a genealogist to map and find all the parents for five million people – with a rate of one person per minute. The AncestryAI algorithm can do the same work in an hour using 50 parallel computers and with a success rate of 65 per cent. The algorithm can also measure the level of uncertainty for each connection so that unreliable results can be ignored.

‘The algorithm does not replace the work of genealogists; it is simply a tool for helping them in their work. The genealogy algorithm can suggest connections which are probably correct, but on its own it is not as precise as a careful genealogist. The algorithm can also search for parents from nation-wide data, while a genealogist may need to limit their search to just one parish,’ explains Eric Malmi, doctoral student at Aalto University who currently works for Google in Zürich.

Malmi will defend his doctoral dissertation at Aalto University in June in the supervision of Aalto University professor and FCAI programme leader Aristides Gionis.


AI improves touchscreen interfaces for users with impairments

A new AI method adapts touchscreen interfaces to make more out of the capabilities of aging users and users with disabilities.

Researchers at Aalto University and FCAI, Finland, and Kochi University of Technology, Japan, developed a new algorithmic approach to user interface optimization that takes individual differences into account.

”The majority of available user interfaces are targeted at average users. This “one size fits all” thinking does not consider individual differences in abilities – the ageing and disabled users have a lot of problems with daily technology use, and often these are very specific to their abilities and the circumstances,” says postdoctoral researcher Jussi Jokinen at Aalto University.

”There are ways to automatically optimize the user interface, but this is efficient only if we have a realistic model of the user.  Previously, designers did not have detailed models that are based on psychological research and can be used to predict, how different individuals perform in interactive tasks."

FCAI Society: understanding and communicating AI across scientific divides

Solving the major technical hurdles in artificial intelligence, FCAI has now brought together the top expertise in both Aalto University and University of Helsinki in the technical development of AI.

However, we still need a holistic view and understanding of artificial intelligence across scientific borders in order to also engage the public in the changes AI will bring.

FCAI has sought experts from philosophy, ethics, sociology, legal studies, psychology and art to explore the impact AI will have in all aspects of our lives.

This cross-disciplinary group, FCAI Society, will in interaction with FCAI researchers consider the wide implications of AI research and furthermore the FCAI Society and FCAI researchers will together engage in public dialogue.

FCAI Society has teamed up with the event venue Think Corner at the University of Helsinki to expose AI research to public interest and scrutiny in an ongoing series of themed events: debates, discussions and demos.

FCAI Society will try to meet the pressing need to engage in dialogue and bridge scientific divides. We will deepen understanding on both sides: both of what is technically possible and how AI methods affect societal change and global equality. The lessons we have to teach each other we will take with us to the public domain and engage everyone in improving our common AI literacy. Here Think Corner’s events, which consistently reach hundreds of people in their prime location in the Helsinki city center and many more online, will have a prominent role.

The group will not remain fixed but expand and change according to the goals, research interests and ongoing projects within FCAI. This way we can have insight into the ways AI methods will live on and be taken up different societal settings. FCAI Society will also remain open to future research collaborations.

Pressing a button is more challenging than appears

Pressing a button appears easy, but the brain needs a probabilistic internal model to control a press. The action appears effortless and one easily dismisses how challenging it is. Researchers at Aalto University, Finland, and KAIST, South Korea, created detailed simulations of button-pressing with the goal of producing human-like presses.

The researchers argue that the key capability of the brain is a probabilistic model: the brain learns a model that allows it to predict a suitable motor command for a button. If a press fails, it can pick a very good alternative and try it out.

"This research was triggered by admiration of our remarkable capability to adapt button-pressing", tells professor Antti Oulasvirta of Aalto University. "We push a button on a remote controller differently than a piano key. The press of a skilled user is surprisingly elegant when looked at terms of timing, reliability, and energy use. We successfully press buttons without ever knowing the inner workings of a button. It is essentially a black box to our motor system. On the other hand, we also fail to activate buttons, and some buttons are known to be worse than others."

How creative can algorithms grow? FCAI researchers in Yle News

Professor Jaakko Lehtinen of Aalto University and FCAI talked with the Finnish public broadcaster Yle on the adversarial neural networks developed with his research team at Nvidia. The networks Lehtinen and his colleagues created were able to create – on their own – life-like but artificial human faces by competing against each other at recognising whether a certain image is real or fake. The networks used a sample set of thousands of actual images of celebrity faces and then gradually went on to create convincing artificial faces.
