Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. Intro:
A Brain-Computer Interface (BCI), also known as a Brain-Machine Interface (BMI), is a technology that
establishes a direct communication pathway between the brain and an external device, such as a computer or
machine, allowing for bidirectional information transfer.
BCIs enable individuals to control external devices or receive feedback directly from their brains, often bypassing
traditional means of interaction like using a keyboard or mouse.
These interfaces can be used for various purposes, including assistive technologies for individuals with
disabilities, neuroscientific research, and even entertainment and gaming.
BCIs typically involve the acquisition and decoding of neural signals from the brain, which are then translated into
commands or actions for the connected device.
his futuristic vision is not science fiction but a rapidly advancing reality made possible by Brain-Computer
Interfaces, or BCIs. BCIs have emerged as a groundbreaking field at the intersection of neuroscience and
technology, enabling direct communication between the human brain and computers or machines.
In this presentation, we will embark on a journey into the fascinating world of BCIs, exploring their history,
current capabilities, and the exciting possibilities they hold for reshaping our relationship with technology and the
human experience.
3. Components:
Neural Signal Acquisition:
Electrodes: Sensors or electrodes are used to record electrical signals from the brain. These
electrodes can be invasive (implanted directly into the brain), semi-invasive (placed on the brain's
surface), or non-invasive (placed on the scalp).
Signal Amplifiers: Amplifiers are required to increase the weak electrical signals obtained from the
brain to a level that can be processed and analyzed effectively.
Signal Preprocessing: Raw neural signals often need preprocessing, which may include noise
reduction, filtering, and signal conditioning.
Signal Processing and Feature Extraction:
Signal processing techniques are employed to extract relevant information from the neural signals.
Feature extraction involves identifying specific patterns or characteristics in the signals that are
associated with particular brain activities or intentions.
Decoding Algorithms:
Machine learning algorithms, such as neural networks or support vector machines, are used to decode
the processed neural signals. These algorithms translate the extracted features into meaningful
commands or actions.
4. User Interface:
A user interface is designed to present feedback to the user and receive their input or intentions. This
could be a graphical user interface (GUI) or other means of interaction, depending on the BCI's
application.
