A machine-learning expert and a psychology researcher/clinician may seem an unlikely duo. But MITs Rosalind Picard and Massachusetts General Hospitals Paola Pedrelli are united by the belief that artificial intelligence may be able to help make mental health care more accessible to patients.

In her 15 years as a clinician and researcher in psychology, Pedrelli says it's been very, very clear that there are a number of barriers for patients with mental health disorders to accessing and receiving adequate care. Those barriers may include figuring out when and where to seek help, finding a nearby provider who is taking patients, and obtaining financial resources and transportation to attend appointments.

Pedrelli is an assistant professor in psychology at the Harvard Medical School and the associate director of the Depression Clinical and Research Program at Massachusetts General Hospital (MGH). For more than five years, she has been collaborating with Picard, an MIT professor of media arts and sciences and a principal investigator at MITs Abdul Latif Jameel Clinic for Machine Learning in Health (Jameel Clinic) on a project to develop machine-learning algorithms to help diagnose and monitor symptom changes among patients with major depressive disorder.

Machine learning is a type of AI technology where, when the machine is given lots of data and examples of good behavior (i.e., what output to produce when it sees a particular input), it can get quite good at autonomously performing a task. It can also help identify patterns that are meaningful, which humans may not have been able to find as quickly without the machine's help. Using wearable devices and smartphones of study participants, Picard and Pedrelli can gather detailed data on participants skin conductance and temperature, heart rate, activity levels, socialization, personal assessment of depression, sleep patterns, and more. Their goal is to develop machine learning algorithms that can intake this tremendous amount of data, and make it meaningful identifying when an individual may be struggling and what might be helpful to them. They hope that their algorithms will eventually equip physicians and patients with useful information about individual disease trajectory and effective treatment.

We're trying to build sophisticated models that have the ability to not only learn what's common across people, but to learn categories of what's changing in an individuals life, Picard says. We want to provide those individuals who want it with the opportunity to have access to information that is evidence-based and personalized, and makes a difference for their health.

Machine learning and mental health

Picard joined the MIT Media Lab in 1991. Three years later, she published a book, Affective Computing, which spurred the development of a field with that name. Affective computing is now a robust area of research concerned with developing technologies that can measure, sense, and model data related to peoples emotions.

While early research focused on determining if machine learning could use data to identify a participants current emotion, Picard and Pedrellis current work at MITs Jameel Clinic goes several steps further. They want to know if machine learning can estimate disorder trajectory, identify changes in an individuals behavior, and provide data that informs personalized medical care.

Picard and Szymon Fedor, a research scientist in Picards affective computing lab, began collaborating with Pedrelli in 2016. After running a small pilot study, they are now in the fourth year of their National Institutes of Health-funded, five-year study.

To conduct the study, the researchers recruited MGH participants with major depression disorder who have recently changed their treatment. So far, 48 participants have enrolled in the study. For 22 hours per day, every day for 12 weeks, participants wear Empatica E4 wristbands. These wearable wristbands, designed by one of the companies Picard founded, can pick up information on biometric data, like electrodermal (skin) activity. Participants also download apps on their phone which collect data on texts and phone calls, location, and app usage, and also prompt them to complete a biweekly depression survey.

Every week, patients check in with a clinician who evaluates their depressive symptoms.

We put all of that data we collected from the wearable and smartphone into our machine-learning algorithm, and we try to see how well the machine learning predicts the labels given by the doctors, Picard says. Right now, we are quite good at predicting those labels.

Empowering users

While developing effective machine-learning algorithms is one challenge researchers face, designing a tool that will empower and uplift its users is another. Picard says, The question were really focusing on now is, once you have the machine-learning algorithms, how is that going to help people?

Picard and her team are thinking critically about how the machine-learning algorithms may present their findings to users: through a new device, a smartphone app, or even a method of notifying a predetermined doctor or family member of how best to support the user.

For example, imagine a technology that records that a person has recently been sleeping less, staying inside their home more, and has a faster-than-usual heart rate. These changes may be so subtle that the individual and their loved ones have not yet noticed them. Machine-learning algorithms may be able to make sense of these data, mapping them onto the individuals past experiences and the experiences of other users. The technology may then be able to encourage the individual to engage in certain behaviors that have improved their well-being in the past, or to reach out to their physician.

If implemented incorrectly, its possible that this type of technology could have adverse effects. If an app alerts someone that theyre headed toward a deep depression, that could be discouraging information that leads to further negative emotions.Pedrelli and Picard are involving real users in the design process to create a tool thats helpful, not harmful.

What could be effective is a tool that could tell an individual The reason youre feeling down might be the data related to your sleep has changed, and the data relate to your social activity, and you haven't had any time with your friends, your physical activity has been cut down. The recommendation is that you find a way to increase those things, Picard says. The team is also prioritizing data privacy and informed consent.

Artificial intelligence and machine-learning algorithms can make connections and identify patterns in large datasets that humans arent as good at noticing, Picard says. I think there's a real compelling case to be made for technology helping people be smarter about people.

There is an uncanniness in listening to a musical instrument you have never heard being played for the first time. As your brain makes sense of a new sound, it tries to frame it within the realm of familiarity, producing a tussle between the known and unknown.

The second album from Mexican-American producer Delia Beatriz, AKA Debit, embraces this dissonance. Taking the flutes of the ancient Mayan courts as her raw material and inspiration, Beatriz used archival recordings from the Mayan Studies Institute at the Universidad Nacional Autnoma de Mxico to create a digital library of their sounds. She then processed these ancient samples through a machine-learning program to create woozy, ambient soundscapes.

Since no written music has survived from the Mayan civilisation, Beatriz crafts a new language for these ancient wind instruments, straddling the electronic world of her 2017 debut Animus and the dilatory experimentalism of ambient music. The resulting 10 tracks make for a deliciously strange listening experience.

Opener 1st Day establishes the undulating tones that unify the record. They flutter like contemplative humming and veer from acoustic warmth to metallic note-bending. Each track is given a numbered day and time, as if documenting the passage of a ritual, and echoes resonate down the record: whistles appear like sirens during the moans of 1st Night and 3rd Night; snatches of birdsong are tucked between the reverb of 2nd Day and 5th Day.

The Long Count of the records title seems to express the linear passage of time itself, one replicated in the eternal, fluid flute tones. We hear in them the warmth of the human breath that first produced their sound, as well as Beatrizs electronic filtering that extends their notes until they imperceptibly bleed into one another and fuzz like keys on a synth. It is a startlingly original and enveloping sound that leaves us with that ineffable feeling: the past unearthed and made new once more.

Korean composer Park Jiha releases her third album, The Gleam (tak:til), a solo work featuring uniquely sparse compositions of saenghwang mouth organ, piri oboe and yanggeum dulcimer. British-Ghanaian rapper KOG brings his debut LP, Zone 6, Agege (Heavenly Sweetness), a deeply propulsive mix of English, Pidgin and Ga lyrics set to Afrobeat fanfares. Cellist and composer Ana Carla Maza releases her latest album, Baha (Persona Editorial), an affecting combination of Cuban son, bossa and chanson in homage to the music of her birthplace of Havana.

While AI-enabled decision-making seems to take out the subjective human areas of bias and prejudice, many observers worry that machine analytics have the same or different biases embedded in the systems.

As with many advances in technology, the legal issues can be unsettled until a body of case law has been established. This is likely to be the case with artificial intelligence or AI. While legal scholars have already begun discussing the ramifications of this advance, the number of court cases, though growing, has been relatively meager up to this point.

Rapid Advances in AI

New and more powerful chips have the potential to accelerate many applications that rely on AI. This solves some of the impediments that have made advances in AI slower than some observers have anticipated. This speeds up the time it takes to train new machines and new models from months to just a few hours or even minutes. With better and faster chips for machine learning, the AI revolution can begin to reach its potential.

This potent advance will bring an array of important legal questions. This capability will usher in new ideas and techniques that will impact product development, analytics and more.

Important Impacts on Intellectual Property

While AI will impact many areas of the law, a fair share of its influence will be on areas of intellectual property. Certainly, areas of negligence, unfairness, bias, cyber security and other matters will be important, but some might wonder who owns the fruits of innovations that come from AI. In general, the patentability of computer-generated works has not been established, and the default is that the owner of the AI design is the owner of the new material. Since a computer cannot own personal property, at present, the right to intellectual property also does not exist.

More study and discussion will no doubt go into this area of law. This will become more pressing as technological advances will make it more difficult to identify the creator of certain products or innovations.

Increasing Applications in Medical Fields

The healthcare industry is also very much involved in harnessing the power associated with AI. Many of these applications involve routine tasks that are not likely to present overly complex legal concerns, although they could result in the displacement of workers. While the processing of paperwork and billing is already underway, the use of AI for imaging, diagnosis and data analysis is likely to increase in the coming years.

This could have legal implications when regarding cases that deal with medical malpractice. For example, could the creator of a system that is relied upon for an accurate diagnosis be sued if something goes wrong. While the potential is enormous, the possibility of error raises complicated questions when AI systems play a primary role.

Crucial Issues With Algorithmic Decision-Making

While AI-enabled decision-making seems to take out the subjective human areas of bias and prejudice, many observers worry that machine analytics have the same or different biases embedded in the systems. In many ways, these systems could discriminate against certain segments of society when it comes to housing or employment opportunities. These entail ethical questions that at some point will be challenged in a court of law.

The ultimate question is whether or not smart machines can outthink humans, or if they just contain the blind spots of the programmers. In a worst-case scenario, these embedded prejudices would be hard to combat, as they would come with the imprint of scientific progress. In other words, the biases would claim objectivity.

Some observers, though, believe that business practices have always been the arena for discrimination against certain workers. With AI, thoughtfully engaged and carefully calibrated, these practices could be minimized. It could offer more opportunities for a wider pool of individuals while minimizing the influence of favoritism.

The Legal Future of AI

As with other areas of the courts, AI issues will have to be slowly adjudicated in the court system. Certain decisions will establish court precedents that will gain a level of authority. Technological advances will continue to shape society and the international legal system.

Research Engineer, Machine Learning job with NATIONAL UNIVERSITY OF SINGAPORE | 279415 - Times Higher Education (THE)

Since 2019, experts at the University of North Carolina at Chapel Hills University Libraries have investigated the use of machine learning to identify racist laws from North Carolinas past. Now a grant of $400,000 from The Andrew W. Mellon Foundation will allow them to extend that work to two more states. The grant will also fund research and teaching fellowships for scholars interested in using the projects outputs and techniques.

On the Books: Jim Crow and Algorithms of Resistance began with a question from a North Carolina social studies teacher: Was there a comprehensive list of all the Jim Crow laws that had ever been passed in the state?

Finding little beyond scholar and activist Pauli Murrays 1951 book States laws on race and color, a team of librarians, technologists and data experts set out to fill the gap. The group created machine-readable versions of all North Carolina statutes from 1866 to 1967. Then, with subject expertise from scholarly partners, they trained an algorithm to identify racist language in the laws.

We identified so many laws, said Amanda Henley, principal investigator for On the Books and head of digital research services at the University Libraries. There are laws that initiated segregation, which led to the creation of additional laws to maintain and administer the segregation. Many of the laws were about school segregation. Other topics included indigenous populations, taxes, health care and elections, Henley said. The model eventually uncovered nearly 2,000 North Carolina laws that could be classified as Jim Crow.

Henley said that On the Books is an example of collections as datadigitized library collections formatted specifically for computational research. In this way, they serve as rich sources of data for innovative research.

The next phase of On the Books will leverage the teams learnings through two activities:

Weve gained a tremendous amount of knowledge through this project everything from how to prepare data sets for this kind of analysis, to training computers to distinguish between Jim Crow and not Jim Crow, to creating educational modules so others can use these findings. Were eager to share what weve learned and help others build upon it, said Henley.

On the Books began in 2019 as part of the national Collections as Data: Part to Whole project, funded by The Andrew W. Mellon Foundation. Subsequent funding from the ARL Venture Fund and from the University Libraries internal IDEA Action grants allowed the work to continue. The newest grant from The Mellon Foundation will conclude at the end of 2023.
