I’m Gavin, a PhD candidate in AI at Bristol. 18
I like technical solutions to philosophical problems.
Technically an EA blog, though I don’t consider this a blog. (Blogging is more speech than writing.)
If you want to talk, get in touch by email, or anonymously here, or extremely privately (via PGP) here.
Some things I'm working on:
- Tensors for fast sampling in big latent variable models.
- Emotion-like behaviour in ordinary RL agents.
- Better ways to communicate preferences to RL agents.
- How inductive logic programming measures up in terms of other ML paradigms
Change my mind
- $1 for nitpicks (typos, ambiguities, misreadings, exceptions, technicalities).
- $10 for an error which falsifies a sentence.
- $50 for an error which invalidates an argument or a post.
Factual and logical errors are most likely to resolve cleanly; I probably won't cough up if you just tell me I'm an idiot for believing or not believing in e.g. Meinongianism. That would get a smile.
I'm not sure how to handle claims that have changed truth-value since I made them; half of this blog might be false if you return in 30 years. Leaning towards $1 to $5.
Also, if I make a claim you want to bet against, get in touch for odds.
|About||Was unclear about the required size of error for a bounty, leading to a prima facie contradiction.||Loki Sempere||$10 to EA Funds|
|/psych||Overstated the consensus against Milgram. It's still shaky, and not really about obedience, but it's wrong to say there's no evidence, just that the original experiments were terrible.||Matt Edwards||$5|
|/gists||I said "constant time" instead of "constant time complexity". The function in question takes 3x more time to process 2^64 than it does 2^0, hence the intermediate payout between nitpick and falsehood.||Loki Sempere||$5|
|Jan 2016: Trump finishes term.||CR||1:1. Nice bottle of whisky.||To me.|
|June 2020: Biden wins election.||CR||1:1. Nice restaurant dinner.||To me.|
I am cause-neutral (in the sense that I will support whatever is highest value, to the extent that objective evaluation is possible) and cause-sceptical (in the sense that we don't really know what the best thing to do is).
Most book reviews are vacuous, blocklike expressions of approval or disapproval. There is nothing in them except the reviewer, their squeals. I do some of those, but I try to do some of the other kind too.

It is equally fatal to the spirit to have a system and to not have one.
So you must combine the two. 1
...there is in men and women a motivation stronger even than love or hatred or fear. It is that of being interested — in a body of knowledge, in a problem, in a hobby, in tomorrow’s newspaper.
The title is an Iain Banks allusion: his powerful protagonists tease pompous people by taking names with as little gravitas as possible. To take the arg min of something is to find the thing which results in its lowest value.

It is some career. So far I have worked on a precision methadone pump, a website generator for bed & breakfasts, secure off-site credit card storage, procurement streamlining for e.g. 'aerospace' companies, a metre-precise 3D model of Britain's rivers, a performance dashboard for use by secondary school teachers, medical risk scoring models, countermeasures against machine-learning model extraction...
I have written production code in
- Python (raw, SciPy/Pandas, PySpark): 9
- C# 11
- Typescript 12
- nodeJS 13
- Pig Latin 14
- bash 15
- Oozie XML 16
- PHP 17
- Java : All my Master's degree work: Game of Life, Vigenere cipher, .
- Scala : Just Project Euler so far.
- Rust : Just Project Euler so far.
- Powershell: e.g. a web scraper (before Python was provisioned).
- bash : An archiver for hyperlinks.
- Jekyll : this itself.

Utterly charming. In the nature of such lists, one does not expect to agree with every, single one---of course not. But the lists exhibit a lively and critical mind, unwilling to follow the usual party lines.– Deirdre McCloskey 6
I'm honoured to be on your list [of favourite books].– Robin Hanson 7
Nice image, young man. You may be a writer.– Will Self 8
Also, my mum says I'm cool.
Anyway I'm not as sure as I sound: there's a comment box under every piece, call me out.
Why so many quotations?
I sometimes regret my instinctual distrust of Twitter: a lot of contemporary aphorists must be whiling away the years on there.
over time amateurs blow their lead by focusing less and relying on easier, more direct methods. They rely more on informal conversation as analysis method, they prefer personal connections over open competitions in choosing people, and they rely more on a perceived consensus among a smaller group of fellow enthusiasts. As a result, their contributions just don’t appeal as widely or as long.
What's with all these accordions?
It also sort of simulates a dialogue with the reader: I plant a question, and then they prompt for the response.
Es ist gleich tödlich für den Geist, ein System zu haben, und keins zu haben. Es wird sich also wohl entschließen müssen beides zu verbinden.

If you count SAS. (If you do, I was employed to code before I learned to Code.)
Note that just being 'employed to code' says surprisingly little about your ability. And almost nothing about your possession of the spiritual advantages of technical life.
- Comment on my "vade mecum" book list including Age of Em.
- Here, 21/11/14.
e.g. a computational linguistics wrapper
e.g. a full notebooked ML pipeline, from sparse raw csvs to GBM to policy implications.
- e.g. An ironclad medicine pump controller with WPF.
- e.g. A CRUD procurement app with Angular and .NET.
- e.g. a secure pharmacy record ("Rx") system.
- e.g. Various YARN batch jobs, processing a few TB then emailing out regular tabular summaries.
- e.g. Debugging HDFS schema issues with Avrotools.
- e.g. chaining Shell and Pig scripts to crunch and mail reports.
- e.g. fairly complex websites, Laravel prototyping, a cURL handler for a credit card storage API.
- A conflict of interest: I am (indirectly) funded by UKRI and so really by the British government.
