Lots of headlines claim graduates are more likely to be unemployed than non-graduates. Graduate unemployment panic makes good headlines, but the data says otherwise. Great analysis by @jburnmurdoch.ft.com. www.ft.com/content/ea9e...

What the graduate unemployment story gets wrong

People with a degree are faring better, not worse than their non-graduate counterparts

New preprint: “Complexity-Driven Policy Optimization”. The paper discusses a novel complexity-driven policy optimisation solution for efficient and robust approximation in Reinforcement Learning. Essentially, entropy alone is not sufficient, we also need "structure".

📢 New Paper!

We replace the entropy bonus in PPO with a *complexity* bonus, encouraging structured and stochastic policies that are robust to different scaling factors and can work in environments with variable exploration needs.

Complexity-Driven Policy Optimization

Policy gradient methods often balance exploitation and exploration via entropy maximization. However, maximizing entropy pushes the policy towards a uniform random distribution, which represents an un...

Received a copy of “The Library of Lost Maps” by my colleague James Cheshire at @uclgeography.bsky.social in the internal mail. Really beautiful (and very interesting) book. Thanks a lot James!

For the geeks among you: just discovered the Apple Calculator app has a "Programmer" mode, complete with binary, hex, and related operations.

The problem is still relevant - we now have Amazon delivery vans instead to play with. 2/2

I was thinking about this some weeks ago. The Travelling Salesman Problem (finding the shortest path through a list of cities, visiting each only once), a classic in Computer Science/Maths, is becoming something of the past without actual salesmen on the roads. 1/2

In the 1980s and 1990s salesmen slogged up and down Britain’s motorways. Today that “road-warrior” lifestyle has disappeared. There are several reasons why

British men are driving less, and a culture is vanishing

Farewell to the road warriors

Wonders of the natural world. I inherited an office cactus from a colleague who left. In a matter of days, out of nothing the cactus has developed a very long stem (with flowers).
