Glacial Lake Mapping Using Remote Sensing Geo-Foundation Model
--
doi.org/10.1016/j.jag.2025.104 <-- shared paper
--
HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

Evaluating generated code isn't just about checking if it executes correctly; it's about measuring its quality and usability against expert standards. Through rigorous testing, user feedback, and advanced metrics, the efficiency of our AI Copilot was benchmarked for real-world application. Let's explore the methodologies that made this possible! #UserFeedback #Metrics

@mike I think a lot of #metrics re #software and espechally #FLOSS are bs.

  • #LinesOfCode incentivize #messy and convoluted source.

  • #PullRequests incentivize a shitload of micro-corrections and "code cleanups" that aren't productive.

  • #Stars incentivize #StarFarming.

  • #Pulls incentivize #Botting.

  • #Sponsors incentivize #Smurfing & #Sockpuppeting. with alt accounts

  • same with #Contributor Numbers and Number of Contributions.

  • Frequency of Commits and changes incentivize constantly pushing empty commits as a sort-of-heartbeat.

  • #Forks doesn't say jack shite (in fact I know companies that do run a git mirror that regularly pulls repos from some public projects of mine.

  • #Donations and #Funding - if any exists at all - only supports massive projects and orgs and not necessarily key components that they too rely upon!

I have no idea suddenly why I decided to write a blog post on help desks, automated ticketing systems and chat bots, but the frustration must have built up for months :D

Want to read about it and see how much this matches your own experience?

And in #Germany it took a Natural Disaster with a triple digit bodycount for #CellBroadcast to be reactivated per legal mandate and #2G to remain online...

The fact that Telstra was unable to say how many devices roamed their Network should be seen as criminal incompetence cuz asking something like: "How many foreign devices are #roaming in your network?" is a standard #FAQ I'd expect them to put into their public financial reports - even as a #footnote re: #revenue [i.e. total devices, total revenue, average Calls / SMS / data per roaming device] cuz that's standard #metrics every #Telco & #ISP does create anyway...

Update. These researchers built an #AI system to predict #REF #assessment scores from a range of data points, inc #citation rates. For individual works, the system was not very accurate. But for total institutional scores, it was 99.8%. "Despite this, we are not recommending this solution because in our judgement, its benefits are marginally outweighed by the perverse incentive it would generate for institutions to overvalue journal impact factors."

So, an #introduction, eh?

I'm a recovering #engineer, former CTO, security researcher, and ex-regulator for #ICSsecurity. I'm now the Director of Cyber Risk at Dragos and I teach (and write) for #SANS.

I've had a lucky career-- I've testified before the US Congress and several federal agencies (as well as a few other countries abroad) and have helped hundreds of industrial organizations improve their #OT security. I've helped write a handful of international standards and I have some strong opinions on what "good" looks like for ICS/OT.

I'll usually write/present on:
#cyberrisk #metrics #technical #standards #engineering #safety #auditing #industrial #ICS #IIoT #governance
...and whatever strikes my fancy. My focus over the past 5-10 years has been more board-level, but I spent a large part of my career in a hard hat trying to fix (and break) industrial systems.

That said, if anyone asks me "what do you do for a living?" I usually avoid talking about myself and instead deviate to more important things... like living a healthy, happy life and helping others where I can.

Oh, and memes. I shitpost memes about how absurd our small community can be some times.
