What is Adversarial?
❖ Adversarial AI is the malicious development.
❖ Adversarial examples are a stark reminders of how different
artificial intelligence and the human mind are.
❖ Adversarial search is a game-playing technique where the
agents are surrounded by a competitive environment.
❖ An adversarial attack is one in which inputs to a deep
learning neural network ultimately result in unexpected
outputs.

What is Robustness?
❖ Robustness is the ability of a computer system to cope with
errors during execution and cope with erroneous input.
❖ Robustness can encompass many areas of computer science.
❖ The robustness is the property that characterizes how effective
your algorithm is.
❖ The robust algorithm is the one, the testing error of which is
close to the training error.

Introduction to Adversarial
Robustness
❖ Adversarial robustness measures a network's resilience against
adversarial inputs.
❖ Adversarial inputs that are produced by taking inputs that are
correctly classified by the DNN.
❖ It is defined as the accuracy of well-trained models on the
adversarial countermeasures of test data generated in white-box
settings.

Adversarial Attacks
5
❖ Adversarial examples are inputs to machine learning models
designed to intentionally fool them.
❖ The main worrying attributes of adversarial attacks are:
-Imperceptibility
-Targeted Manipulation
-Transferability
-Lack of theoretical model

Introduction to Clever Hans
8
❖ A Python library to benchmark machine learning systems'
vulnerability to Adversarial Examples.
❖ This library uses Jax, PyTorch or TensorFlow 2 to accelerate graph
computations performed by many machine learning models.
❖ Once dependencies have been taken care of, you can install
CleverHans using pip or by cloning the official Github repository.
