What is entropy?

You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and …

So, How Do You Get a Job? | Institute for Mathematics and its Applications

I was late. I only decided to find a job in industry in the 4th year of my graduate study even though I never had a job outside of academia. The one question that I kept asking was: how do you get a job? It was scary because I did't know what to do. But I…

🔸What does it mean to be central in a complex network? Nobody knows, b/c there are many distinct ways of being central. Our recent work, led by our great @GiuliaTtt, attacks the problem from a #stats perspective: the most central node is the median of the network.

Data-driven inference of hidden nodes in networks

Complex systems, for example in biology or social science, can be viewed as networks of interacting nodes whose behavior can only be partially observed. The challenge is to understand the system's dynamics based on this partial information. This paper presents…

⚠ A mathematical model from 103 years ago predicted something that was seen for the first time today: a #black_hole.

#MachineLearning could never do that: it needs observations to model anything. This is a major weak-point of ML. Let's fix it.

A stark contrast between Machine Learning vs other forms of mathematical modeling is that ML models often don't model extreme corner cases very well, because #data in those areas is rare. Gathering data in important areas is as important a skill as building fancy neural networks.

Sadly, too often, using extreme inputs to a model is more useful: e.g. by modeling physics of levers on light objects with short levers, we then built very long levers to lift extremely heavy things. Instead, ML is better suited at modeling everyday phenomena with complex models.
