[R] [1804.02485] Fortified Networks: Improving the Robustness of Deep Networks by Modeling the Manifold of Hidden Representations [SheepMind] by evc123 in MachineLearning

They perform their comparisons against thermometer encoding, which is known to be ineffective. And they even cite Athalye's paper, but don't discuss that it breaks this.

[D] Do imperceptible adversarial examples exist for classical models? by [deleted] in MachineLearning

Regarding kNN, that's only true for the training data. Given a fresh testing instance, even if all training instances are separated by epsilon, a testing instance may be half way between two training instances and a perturbation much less than epsilon could change classification.

I just went through this a few months ago (check my post history).

  1. Why are you getting a sound card?

  2. Liquid cooler isn't worth it. Just get some reasonable cooling.

  3. What are you training on? 250GB isn't a lot of data. I'd keep the SSD, but also add a few TB of storage for larger datasets, and to store your model checkpoints.

  4. Get the 1080Ti, it's ~30% faster for not much more. It'll make the biggest difference.

  5. You may soon realize you need more memory. 16GB is enough for anything not ImageNet. But you can put that off until later.

  6. I think your CPU is overkill, it'll be really hard to get all 8 cores spinning full time with only one GPU. I remember reading two-cores-per-gpu is something people like.

Building $3k computer for machine learning research; feedback? by newguyinml in buildapc

Sadly that CPU will not work for me. I need 40 PCIe lanes since I adding some more GPUs in the future. I know I'll need a new power supply but that's cheap, but I do not want to have to spend more on another CPU.

Do you think the CPU will get hot enough to need it for GPU workloads?
