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.

• A set of activities whose goal is the development or
evolution of software.
• Generic activities in all software processes are:
• Specification - what the system should do and its
development constraints
• Development - production of the software system
• Validation - checking that the software is what the customer
wants
• Evolution - changing the software in response to changing
demands.
13. What is a software process
model?
• A simplified representation of a software process, presented
from a specific perspective.
• Examples of process perspectives are
• Workflow perspective - sequence of activities;

• Tools to support later activities such as programming, debugging and
testing.
19. What are the attributes of good software?
• The software should deliver the required functionality and
performance to the user and should be maintainable, dependable and
acceptable.
• Maintainability
• Software must evolve to meet changing needs;
• Dependability
• Software must be trustworthy;
• Efficiency
• Software should not make wasteful use of system resources;
• Acceptability
• Software must accepted by the users for which it was designed. This means it
must be understandable, usable and compatible with other systems.
20. What are the key challenges facing software
engineering?
• Heterogeneity, delivery and trust.
• Heterogeneity
• Developing techniques for building software that can cope with
heterogeneous platforms and execution environments;
• Delivery
• Developing techniques that lead to faster delivery of software;
• Trust
• Developing techniques that demonstrate that software can be trusted by
its users.
21. Professional and ethical
responsibility
• Software engineering involves wider responsibilities
than simply the application of technical skills.
• Software engineers must behave in an honest and
ethically responsible way if they are to be respected as
professionals.
• Ethical behaviour is more than simply upholding the
law.
22. Issues of professional
responsibility
• Confidentiality
• Engineers should normally respect the confidentiality of their
employers or clients irrespective of whether or not a formal
confidentiality agreement has been signed.
• Competence
• Engineers should not misrepresent their level of competence.
They should not knowingly accept work which is outwith their
competence.
23. Issues of professional
responsibility
• Intellectual property rights
• Engineers should be aware of local laws governing the use of intellectual
property such as patents, copyright, etc. They should be careful to ensure
that the intellectual property of employers and clients is protected.
• Computer misuse
• Software engineers should not use their technical skills to misuse other
people’s computers. Computer misuse ranges from relatively trivial (game
playing on an employer’s machine, say) to extremely serious
(dissemination of viruses).
24. ACM/IEEE Code of Ethics
• The professional societies in the US have cooperated to
produce a code of ethical practice.
• Members of these organisations sign up to the code of
practice when they join.
• The Code contains eight Principles related to the
behaviour of and decisions made by professional
software engineers, including practitioners, educators,
managers, supervisors and policy makers, as well as
trainees and students of the profession.
25. Code of ethics - preamble
• Preamble
• The short version of the code summarizes aspirations at a high level of
the abstraction; the clauses that are included in the full version give
examples and details of how these aspirations change the way we act as
software engineering professionals. Without the aspirations, the details
can become legalistic and tedious; without the details, the aspirations can
become high sounding but empty; together, the aspirations and the
details form a cohesive code.
• Software engineers shall commit themselves to making the analysis,
specification, design, development, testing and maintenance of software
a beneficial and respected profession. In accordance with their
commitment to the health, safety and welfare of the public, software
engineers shall adhere to the following Eight Principles:
26. Code of ethics - principles
