Protecting your #DeepLearning model will be the key area to focus on from cyber attacks to your models and algorithms.

Placing these is public cloud environments may severely affect your ability to protect these models and algorithms.

You need to prepare to defend these.

What are these adversarial attacks?

1. l2-norm attacks: in these attacks the attacker aims to minimize squared error between the adversarial and original image. These typically result in a very small amount of noise added to the image.
2. l∞-norm attacks: this is perhaps the simplest class of attacks which aim to limit or minimize the amount that any pixel is perturbed in order to achieve an adversary’s goal.
3. l0-norm attacks: these attacks minimize the number of modified pixels in the image.

Below is an example of an l2-norm attack where the left is classified as jeep but the right as a minivan.

Not everyone knows but my #book has its Github repository where all #Python code used to build illustrations is gathered.

So, while reading the book, you can actually run the described #algorithms, play with hyperparameters and #datasets, and generate your versions of illustrations.

George Box's observation that "Essentially, all models are wrong, but some are useful" is one of the most quoted of all statistical proverbs.

However, we need to ask "Useful for what?"

There are many #machinelearning #algorithms and statistical models that are difficult to interpret but useful in predictive analytics. Sometimes all we need are predictions and classifications that are sufficiently accurate for decision purposes.

Often in the business world there is little or no theory to guide statisticians and data scientists. Moreover, we may not have the data necessary for a good understanding of why some customers are heavier purchasers of our product than others, for instance.

That said, predictions and classifications that are "accurate enough" often aren't good enough. We may need a reasonable - if imperfect - understanding of the Why for these predictions and classifications to be useful.

This is obvious in "hard" scientific research but just as true in the behavioral and social sciences, marketing included.

Being able to design primary studies and having a good grasp of causal analysis, IMO, is necessary to be a full stack analytics professional, as opposed to being a full stack programmer or IT professional. These are different occupations.
