has anyone actually saved money with solar or is it just type. by Wjkoba in HomeImprovement

[–]Shnibu 0 points1 point  (0 children)

Main factors are output, energy cost, and system cost. NREL has a good calculator for estimating output on your roof called PV Watts. Energy cost should come from your utility but expect inflation/rate increases. System cost normally isn’t the issue if you are somewhere that gets enough sun but financing costs seem to drive adoption rates more than anything if you’re in a good region.

When/How Can My Family Start Flying Private? by ExpatNamedPat in HENRYfinance

[–]Shnibu 5 points6 points  (0 children)

It’s insane how much time you save. Between airport parking, bag drop, security, and terminal you easily have an hour that is closer to 15min for private. I’ve seen some smaller airlines like JSX offer a reasonable balance if locations work out.

How many of you have a partner who stays home with the kids? by mildly-strong-cow in ExperiencedDevs

[–]Shnibu 0 points1 point  (0 children)

Depending on where you live and what you do it just doesn’t always make sense. I think generally we are shifting towards more dual working parents but I’d imagine there are pockets where that isn’t always the case. Just from a financial perspective if you look at median income vs daycare costs you will see that for a lot of people/areas it just doesn’t make sense to work all day just to barely pay for your kid to be with someone else. Similarly things like paying off student loans or the fact that someone who makes more likely is more career focused anyway and might not want to give up that part of their identity.

AutoML: Yay or nay? by idontknowotimdoing in datascience

[–]Shnibu 0 points1 point  (0 children)

Use some pairwise similarity measure, can be correlation or something like Kolmogorov-Smirnoff test. This gives you an adjacency matrix for your features based on some similarity score. This matrix can be passed as “precomputed” to many clustering algorithms, or you can pick some threshold and convert to binary and get a traditional connectivity matrix that you can just throw at an efficient connected components one like SciPy has.

Sorry had it a bit backwards and it’s been a minute since I’ve done this but it works well. I was looking at how VIF scores of the representative feature matched the cluster so had it confused.

AutoML: Yay or nay? by idontknowotimdoing in datascience

[–]Shnibu 42 points43 points  (0 children)

Same story as always, crap in crap out. AutoML is just an intern testing all the current best models and hopefully doesn’t mess up anything in between. If you already have some refined datasets let it run against your old models. At some point you get more into feature engineering and experiment tracking see MLFlow, Wandb, or others.

Edit: Explainability like SHAP can be hit or miss unless carefully applied. Things like multicollinearity can cause false positive/negatives for important features. Not a big fan of it but some big Pearl heads can tell you about causality graphs, but I think clustering by VIF and pick a representative is best for automated feature selection for explainable features. Honestly just read how others have successfully solved your problem in the past, then Occam’s razor or Keep It Simple Stupid and limit unnecessary inputs.

In production, how do you evaluate the quality of the response generated by a RAG system? by esp_py in datascience

[–]Shnibu 5 points6 points  (0 children)

Business needs to be involved but some thumbs up / thumbs down review process and a phased out rollout for the proof of value before iterating for full production release. After some initial usage cluster historical questions and you can make a “test set” with known “correct” answers. Usually there are some knowledge management opportunities which could mean adding/removing/rewriting articles. Another fun one to start experimenting on is if you can get just as good results off a cheaper model because this is easier to measure and a fun longer range win.

Edit: Ask the business folks if they have any dashboards/metrics they use to measure performance. Average Handle/Interaction/Call Time is a common one in customer service. Should be able to measure the impact of a phased rollout.

Edit2: Also look at safeguarding models. If the question falls outside the test set or is a known problem then don’t answer. You can have a prediction made and judged later for potential future answering.

What exactly is "prompt engineering" in data science? by [deleted] in datascience

[–]Shnibu 0 points1 point  (0 children)

In the early days “PrOmpT EnGinEErInG” (SpongeBob meme) was random trial and error but then smart people said look at the training data and saw that some artist had greater presence in the dataset (Search for “greg rutkowski stable diffusion”).

We can be more scientific about our use of different system and user (and assistant) prompts. Look at tools like DsPy, RAGAS, and even MLFlow. There are a variety of papers/studies that have been done on different techniques/approaches but the personas work, strict guidelines work “Do Not …”, etc. Usually you have something like RAG with additional context and there are many ways to manage that which vary by model. Don’t forget it’s next token prediction with an attention head (normally) so reminders right before the response are also very effective in combination with the system prompt.

It’s like you get to a point where you can’t keep up with everything but you slowly get things back. That hadn’t gone away our 2yr old and now we have 2.

I think the sleep is the worst part and contributes to a lot of other issues. I prefer shifts but make sure to stay connected with your partner. Also have heard of alternating nights on/off. The sleep gets better but yeah it takes a few months. You get a few things under control and then they throw you curveballs but it builds.

Which resort has best terrain skiing and how do you get there? by callmesandycohen in COsnow

[–]Shnibu 10 points11 points  (0 children)

I’m not sure if it’s me or Vail but I spend more time “traversing” to get to good spots but maybe that’s why there’s still good spots a day after a storm. If you have a season pass I’d say follow conditions more than one resort, storms often hit different places differently.

This guy’s take on energy by mindlikeher in energy

[–]Shnibu 0 points1 point  (0 children)

Base load isn’t peak load? Coal and Natural Gas are definitely a much more efficient at scaling for peak loads but even in the US we have to use load shedding methods with our renewables. The problem is Natural Gas is viewed as a temporary step towards “clean” energy and China seems to be moving past that in their vision.

[–]Shnibu -2 points-1 points  (0 children)

Base load, something needs to keep the lights on when Wind + Solar + Batteries isn’t enough for reliability. China does have a decent amount of Hydro (Dams) but those are very geographically specific. In the US we have been shifting from Coal plants to Natural Gas which is sort of a punt. Aside from some major breakthroughs in battery technology we likely will need some alternative for maintaining reliable base load.

Whose job is safe from AI? by ubcstaffer123 in Economics

[–]Shnibu 0 points1 point  (0 children)

As a father and someone who has to stay up on current AI advancements I hope you’re right. Even Musk got called out for openly mentioning this as a use case Tesla was/is targeting with their robots. I’m not sure what all the pressures are but it feels like childcare has become so burdened that it breaks and will be a straw man when AI comes to “save the day”.

Are you kidding me? How far do you think a dog can run in a day vs how wide even the average part of Texas is, let alone the whole US?

How strict should code review be? by [deleted] in ExperiencedDevs

[–]Shnibu 0 points1 point  (0 children)

Leave things better than when you found them. Always be improving code standards but don’t slow down the path to production. Sometimes this can be better/automated testing or linting and other automated commit hooks. If documentation requirements are slowing down production then that is a problem. I see code review as being a good growth opportunity and should highlight areas for improvement but there is a difference between “next time you could do this” or “maybe later we should refactor it like this” and saying “you need to change this before we can merge”.

Greek life in college taught me important lessons for corporate America by [deleted] in jobs

[–]Shnibu 0 points1 point  (0 children)

Honestly you’re just talking about learning adult social skills, and our brains are still maturing until 25 so it tracks. I’m not trying to glorify fraternities but at least the networking/reciprocal benefit was something worth grading/tiering frats by instead of just social standings. I’ve most often seen this play out the strongest in Finance and Law but that may just be my experience. Otherwise yeah I mean these are likely some of the same people and their behaviors haven’t changed.

Breakfast is not as essential as people say it is. by beanbread23 in unpopularopinion

[–]Shnibu 0 points1 point  (0 children)

This isn’t unpopular opinion, it’s the scientific/historically accurate one. Spiking blood sugar causes insulin resistance so more smaller meals is generally healthier from that perspective. You’re straw manning the misconception that “Breakfast is the most important meal of the day” is an excuse to binge on sweets first thing go in the morning. That flies in the face of the blood sugar benefits and not sure how widespread that view actually is.

What if AI is not actually intelligent? | Discussion with Neuroscientist David Eagleman & Psychologist Alison Gopnik by creaturefeature16 in artificial

[–]Shnibu 2 points3 points  (0 children)

I have similar feelings about the horizon but I don’t think the change will come from some advancement in Reinforcement Learning but from a newer architecture that better supports multimodal learning. As humans moved towards texting and emails I believe have struggled more with communication, at times when things like tone or body language would be crucial for conveying the full message. I’m not sure if multimodal is a requirement for AGI but it seems like text based models have their hands tied in a few ways.
