materials engineering with active learning</i></span></p>
<p><span style="font-size: 10pt"><span style="font-size: 11pt">Data-driven materials
science based on artificial intelligence (AI) algorithms has
facilitated breakthroughs in materials optimization and
design. Of particular interest are active learning algorithms,
where datasets are collected by sampling on-the-fly in the
search for optimal solutions. We encoded such a probabilistic
algorithm into the Bayesian Optimization Structure Search
(BOSS) Python tool for materials research. We utilized this
versatile tool to study functional materials, like molecular
surface adsorbates, thin films, solid-solid interfaces,
molecular conformers, and even to optimise experimental
outcomes. Agreement between optimal solutions and experimental
measurements suggests that active learning is capable of good
accuracy at computational costs up to 10 times smaller than
other approaches. New algorithms combining batch and gradient
acquisitions with multi-fidelity schemes will allow us to
harness the power of exascale computing platforms for
next-generation materials engineering. <br>

<p>Welcome!<br>
</p>
<p> Coffee will be served in the lobby. You can also join via Zoom
(with your own coffee). We will do our best to make sure that
everyone is capable of listening to the talk and asking questions.
However, we ask for some patience in case of small technical
glitches. <br>
</p>
<p>The confirmed near-future colloquium talks are<br>
<br>
2.12. Ferrucio Renzoni (UCL) <i>Atomic magnetometry</i><br>
</p>
<p> Do you wish to suggest further topics for the colloquium? You
can do so <a href="https://jyu.sharepoint.com/:w:/r/sites/CafJYFLDepartmentofPhysics/Jaetut%20asiakirjat/General/Physics%20colloquium%20ideas.docx?d=w888a107ea28543c7a9bc331f12a99995&csf=1&web=1&e=r5iubT">at
Café JYFL</a>. There are still a couple of open slots (and
budget) for the fall, and much more so for the spring, so
suggestions are welcome.</p>
