dollo_7··on TinyLoRA – Learning to Reason in 13 Parameters
Not sure if I buy it. First, SVD decomposition to obtain U, Σ, V is computationally expensive, so it would work only if we are not finetuning very big models.

But my real concern comes at the results. The "13 parameters" looks like bait, because it is one result of finetuning a model on a very simple math benchmark, grade-school-math (GSM8K), an already very saturated benchmark on every model. Besides, it seems to happen only for the qwen family model... It looks like GSM8K was part of the training set of the qwen model, and this tinylora finetuning did the last adjustments to perfectly reflect that overtraining.

dollo_7··on SensorLM: Learning the Language of Wearable Sensors
Very interesting. We will see soon a rise of training assistants reading through our wearable sensors.

Sadly, it seems these foundation models are still not open to the public. I can't find any links within the research page or the paper to tinker a little bit...

dollo_7··on The danger of the mediocre success when testing startup hypotheses (2023)
It is also about trying to get the most of that hypothesis testing, defining success and failure the best you can.

I have encountered this "mediocre success" many times in AI solutions due to lack of problem definition. For instance, now with LLMs is very easy to write a prompt that gives you the output you want in 5 or 6 examples you have in mind. The problem is to build up your testing scenario from there, and gather as much data as possible until you make it representative of your use cases.

That is the only way to actually test your prompts, RAG strategies, and so on, instead of buying the last CoT-like prompt trend.

I'm not sure if that is a metric you can rely on. LLMs are very sensitive to the position of your item lists along the context, paying extra attention at the beginning and the end of those list.

See the listwise approach at "Large Language Models are Effective Text Rankers with Pairwise Ranking Prompting", https://arxiv.org/abs/2306.17563

dollo_7··on Building reliable systems out of unreliable agents
I hoped it was too good to be just a joke. Still, I will try it on my eval set…

dollo_7··on Ask HN: What happened to fuzzy logic?
Academic silo with little to no real transfer to business. ML eventually enabled building better continuous and discrete models for inference, control, and prediction.
dollo_7··on Thinking hard makes the brain tired
I have sometimes found myself into that situation. I have to be careful not to overthink where to put my "brain room" for that day, otherwise I carry this overhead burden that rumbles all day long, questioning if I should be putting that effort elsewhere.

Definitely, brains are fun. They can be your best ally and worst enemy.

dollo_7··on Every modeler is supposed to be a great Python programmer
I totally agree. I work on the private sector, coming from a research position too. I was also focused on the "interesting" side of the problem: the modeling, integrating domain knowledge into the analysis, drawing all sorts of plots... But there were other unavoidable and "uninteresting" needs for the research project, like building a data gathering system with its API and everything. This required my best software engineering abilities. Needless to say my best weren't precisely THE best, so as the project got bigger, the not-so temporary fixes increased, as well as poor design choices (if any). This finally led to a complete reestructure and almost fresh start.

I feel some of it could be avoided, so I learned the hard way that the whole modelling + software engineering process is a subtle craft. It is important to take care on the implications of your code and, specially, on how its done, since it may fall back onto you eventually. This reconciled me with the more technical stuff (my tools) to eventually put up a good work in a more satisfying way.

dollo_7··on Power struggles among nice people
I believe the article is oriented to those who feel like the "nice guy" the author is describing, which is my case, and expects you to act on how you feel to his words. I feel myself very reflected on the profile seeking for high affiliation, low power, and high emotional control; however, I am not sure to what extent should it only focus to a work environment.

Over the time, I have found myself more willing to fight over my "slice" of power in the workplace, making my demands assertively and showing that I know my value without traces of regret or false humility. That is something I have had to work on a lot, it makes me uncomfortable; but I understand that I "deserve" some power. If I am doing things right I cam claim my state for influence and being heard. I think this aligns with your point on being responsible with yourself and not just being a bystander.

On the other hand, there are other spheres in which I do not expect such power beforehand, so I'm not usually ready to draw my weapons. This may be a social encounter with barely-known people, friends, or even family. There are power fights there too, but somehow they feel different. Maybe I'm not as convinced of how I deserved such power, or maybe I'm not willing to do the effort anymore and I just want to fulfill my affiliation urge.

dollo_7··on Nicheless: a micro-blogging platform
While you have a point, this process may make it harder to be a troll. Nowadays you can be a troll anywhere and anytime you want, specially online. I'm curious how this approach may benefit those who share their plain thoughts without the fear of being automatically targeted by trolls looking for triggered responses and tribal support.
dollo_7··on Don't ignore the janitor
The author's point of view seems to me quite condescending. Like being the janitor is considered less (and that, inevitably, everybody sees the janitor that way), so the author is trying to flip that view around (because he can, he is "not less").

Needless to say that being polite is out of the question here, and that I am sure that the author's intentions are not what I just commented, but I can't help to read it that way.

I would agree that "please" and "thank you" can take you far, however you don't just have to address them to the janitor, it's for everybody.

dollo_7··on Don’t think to write, write to think
I also found writing useful to stop my head from circling around problems repetitively. Writing serves me not only to think, but to actually see the structure of that thinking process (a beginning and an end, argumentation), hence seeing the whole picture and how I am are not deliberately missing something.

This eventually frees me to focus in other things, feeling that I did as much as I could with the thinking at that moment. New ideas may come eventually, but for the moment that thinking "batch" is ok.

dollo_7··on The silent majority in software
I may belong to that silent majority. I have learnt a lot from the discussions here in HN and other sites, but I rarely participate on them. This post made me think about being a little more active because, sincerely, most of the times it is just laziness what prevents me from commenting anything.

In fact, this is my first comment here in HN. Little by little.
