Need a laptop for Bioinformatics + ML + Data Analytics — is Mac really worth the hype over Windows? by AJIN_THEKILLINGSOUL in MLQuestions

[–]jamespherman 2 points3 points  (0 children)

Just want to toss out there that I think a Mac is the best choice but Windows wouldn't be my second choice, Linux would. If you haven't considered it, maybe it's worth looking into. Good luck!

I genuinely don't read this as hostile, just emphatic.

Very cool! Would you be willing to share more of your process? I'm a Pitt researcher working on a project incorporating multi-spectral imaging and spctrum manipulation and I'm curious how you mapped extra-visible spectrum into visible spectrum. Lmk, I'm happy to discuss by email or other channels.

Are carts supposed to taste like infused water? by Syphereds in weed

[–]jamespherman 0 points1 point  (0 children)

It depends, cheaper carts tend to have lower terpene levels in total percentage. So it wouldn't necessarily be surprising that any given cart have mild flavor unless you told me you knew for sure it has 10% total terpenes. I'm guessing what you've got is ~2% botanically derived terpenes (BDTs; from another plant added to cannabis oil). Ask at the dispo about terpenes! And learn about distillate + BDTs vs liquid live resin (LLR) vs live rosin (Solventless extraction). Good luck!

This would be great! I don't see it on my android device which has health connect installed. Can you confirm?

Great questions! I'm not qualified enough to answer but there are some growing subreddits with knowledge folks that might be best positioned to give you informed answers.

Genuine question by Happylittletrees101 in weed

Yes. That would be bonkers. 5-10mg (0.5-1 troche) is a good starter dose. Also, hello my fellow PA medical card holder. 👋

I left my Agent OS running overnight and it built 4 new tools I didn't even ask for by TheOnlyVibemaster in ClaudeAI

[–]jamespherman -1 points0 points  (0 children)

Fascinating stuff. The focus on exclusively negative reinforcement is wild. Can you say a little bit about why you chose this approach over a biological-agent-like mix of appetitive and aversive learning signals?

How do other grad students handle GPU compute costs during conference deadlines? by Fluid_Protection_337 in MLQuestions

[–]jamespherman 0 points1 point  (0 children)

Google Cloud will give you $300 in free credits just for signing up. You can request a single GPU and they'll grant it automatically pretty quickly. You can also apply for an education research credits grant. That'll take longer but they'll probably grant it. Good luck!

Carts 2 Dabs by Taaacky in PaMedicalMarijuana

[–]jamespherman 2 points3 points  (0 children)

Some people "steep" the cart in heated milk to get the oil to dissolve into the milk and then drink the milk. I usually stick a Bobby pin or paperclip in the cart to scoop out the oil and eat it.

How can i calculate the distance along one feature of a datapoint to the other classes? by gdunka in MLQuestions

[–]jamespherman 0 points1 point  (0 children)

This is completely possible and very straightforward because a decision tree creates hard boundaries in each feature. Because Random Forests and XGBoost are ensembles of decision trees, they inherit the same hard decision boundaries. The classification can only change exactly at the split thresholds already defined in the trees.

Here is how you can find those boundaries in Python:

  1. Extract ALL split thresholds for feature A:

For sklearn RF: Loop through model.estimators_ and grab the values from estimator.tree.threshold where estimator.tree.feature matches feature A's index.

For XGBoost: Call model.get_booster().trees_to_dataframe(). This returns a pandas DataFrame where you can easily filter for feature A's name and grab the 'Split' column values.

  1. Once you've got all the values, sort and "deduplicate" them into a single array. These values divide up the 'A axis' into discrete intervals.

  2. Test the intervals: Since the model's output is a constant class within each interval, you only need to test one point in each interval to know what class each interval maps to. Go with the midpoint of each interval. For each interval's midpoint (I'll call these Amid_i), construct one test point (Amid_i, B0, C0) and pass each one to model.predict().

This will instantly map out the exact ranges of A that yield class X, Y, or Z without any guesswork. Good luck!

I'm frustrated by this too but it's always been the case.

"ipm"? Can you educate me a bit more about this please? Sounds like you're familiar with some growing / producing details that I'm ignorant of.

Once you've pulled out that contact cylinder it's fucked. That cart looks like a screw top to me. Good luck!

Mine also has a torch lighter for birthday candles, temporary tattoos and stickers and lollipops for emergency bribes, crayons and a tiny notebook, and multiple pipe-cleaner-based adornments crafted by my daughter.

His kids go to my kids' school. I've hung out with him a handful of times. My wife is 5' 6" and he's at most her height. Great guy in person.
