This practical guide reviews the 'why' and 'how' of multi-objective reinforcement learning.

In mid-2025 I reported fake references in a 2023 paper to NeurIPS Ethics and Grievances Committee. They said they had contacted the authors, who apologized & sent a corrected version. This story prompted me to check the NeurIPS proceedings, and it's still the original, uncorrected pdf.

If I were a foreign power doing "foreign interference" on a tiny fraction of Australian research projects, I wouldn't believe my luck that Australia's response was to extend grant time-scales to 16 months while failing to reverse its systematic decline in research funding.
Talk about bang-for-buck!

If the government wants research to work more with industry, they need to sort this out. It's impossible to plan anything with industry partners when you have to tell them its over a year to know whether a grant is successful or not.
⁉️The ARC has delayed outcomes of ALL grants 1–4 months & increased scheduled outcome windows from 2 weeks to 3 months!
This reverses 4 years of progress in providing greater certainty & ability to plan for researchers, their families & unis.
Their excuse? Security checks under new ARC legislation👇

I was standing on a chair to get wrapping paper down from a top shelf. Stepped off the chair directly onto a cast iron doorstop with a scalloped upper edge, in my bare feet. It looked like I'd attacked my sole with an ice-cream scoop. Result: multiple stitches & 2 months on crutches.
What's the most ridiculous way you ever hurt yourself? I got out of the tub, skidded in water and tripped over the toilet. Ankle sprain.

It's a new year, and that means it's time for my annual quantitative review of multi-objective reinforcement learning research. Yet again this year saw a substantial increase in the number of papers mentioning MORL, exceeding 2000 for the first time ever. 1/3

Datacenters in space are a terrible, horrible, no good idea.
There is a rush for AI companies to team up with space launch/satellite companies to build datacenters in space. TL;DR: It's not going to work.

We’ve all seen the evidence that ARC are already stretched. They already outsource so much admin to university research offices – duplication across all unis – & have zero capacity to inform the public about what tax-payer money is funding.
Their response? Reduce capacity further!
Utter nonsense!

ARC are considering a restructure in which jobs there will be lost, a source tells me.
This seems ridiculous when they're about to completely overhaul the entire grants system – they've never undertaken anything so large before!
I've long said ARC needs MANY MORE staff, & should do more, not less.
