I asked it about nukes.

"Today, nuclear weapons are among the most powerful weapons in the world and have been used in multiple conflicts, including the Cold War and the wars in Afghanistan and Iraq. The development and use of nuclear weapons has had a profound impact on the world and continues to be a major concern for governments around the world."

Someone suggested active learning, but it may be more suitable to look into the subfield of data valuation.

Data valuation broadly aims to assign values to data points that represent their contribution to a model’s overall performance. Many methods are based on game theoretic solution concepts such as the Shapley value and are therefore very expensive to compute. In practical settings, I would suggest the Shapley over kNN surrogate by Jia et al. (2019) or LAVA by Just et al. (2023).

You can find more papers at the GitHub repo awesome-data-valuation.

Hope that helps!

Unfortunately, most code out there is using calls to cuda explicitly rather then checking the GPU type you have and using that. You can fix this yourself, (I use an m1 macbook pro for ML and it is quite powerful) but you need to know what you're doing and it's just more work. You might also run into situations where things are not fully implemented in Metal Performance Shaders (the mac equivalent to cuda), but Apple does put a lot of resources into making this better

Not entirely the same thing. VAEs offer approximate likelihood estimation, but not exact. The difference here is key - VAEs do not optimize the log-likelihood directly but they do so through the evidence lower bound, an approximation. Flow based methods are exact methods - we go from an easy tractable distribution to a more complex one, guaranteeing at each level that the learned distribution is actually a legit distribution through the change of variables theorem.

Of course, the both (try) to learn some probability distribution of the training data, and that is how they would differ from GAN approaches that do not directly learn a probability distribution.

ResNets do not tackle the vanishing gradient problem. The authors specifically mention that the issue of vanishing gradients was already fixed because of BatchNorm in particular. So removing BatchNorm from the equation will most likely lead to vanishing gradients.

I am assuming you are doing a WGAN approach since that would explain the gradient penalty violation. In this case, use LayerNorm as indicated here: https://github.com/LynnHo/DCGAN-LSGAN-WGAN-GP-DRAGAN-Tensorflow-2/issues/3

If I search on Google: "how to do cardiac bypass surgery", it will give me any number of results about cardiac bypass. That doesn't mean Google is a medical aid or a reliable surgery assistant. It's a search engine, it's used to find stuff.

Reply to comment by Nikelui in [P] TherapistGPT by SmackMyPitchHup

I just wrote to ChatGPT "I'm feeling a bit depressed, can you help me?"

Here is the reply:

"I'm sorry to hear that you're feeling depressed. While I am just a language model and cannot provide medical advice or treatment, I am here to offer support and guidance.
It's important to remember that depression is a medical condition and it's not something that you can just snap out of or will away. However, there are things you can do to help manage your symptoms and start feeling better.
Here are a few suggestions:
Talk to someone: Talking to a trusted friend or family member can help you feel less alone and provide emotional support.
Seek professional help: Consider speaking with a therapist or a mental health professional who can provide you with the appropriate diagnosis and treatment.
Get active: Regular exercise can help alleviate depression symptoms by releasing endorphins, which can improve your mood.
Practice self-care: Make sure to take time for yourself and engage in activities that bring you joy and relaxation.
Challenge negative thoughts: Try to identify negative thoughts that may be contributing to your depression and challenge them with positive affirmations or alternative perspectives.
Remember, it's important to be patient with yourself and seek help when you need it. Don't hesitate to reach out to a medical professional or a crisis helpline if you're feeling overwhelmed or in crisis."

Sounds like a mental aid to me for some queries, so not totally outside the scope of ChatGPT.
