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.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Methodology and Design
• Definition of key terms
• The structure of knowledge
• Essential attributes of research
4. Antonio Gramsci
• An Italian political scientist (Marxist), most well
known for his theories on civil society vs. political
society.
– he said “the point of modernity is to live a life without
illusions while not becoming disillusioned”.
– modernity is a rejection of the traditional in favour of
the principles of the Enlightenment (reason and
analysis)
– why is this relevant to research methodology?
• what is research?
• what is (scientific) knowledge?
• what is reality?

6. Key Definitions
• What is RESEARCH?
– An activity whose purpose is the generation of new
knowledge by means of scientific method(s)
• In more detail …
– Frascati Manual (OECD); research and experimental
development comprises creative work undertaken on a
systematic basis in order to increase the stock of
knowledge, including knowledge of man (sic), culture
and society, and the use of this stock of knowledge to
devise new applications

Questions
8. Theory and Practice
• Theory is when you know everything but nothing
works
• Practice is when everything works but no one knows
why
• In our lab, theory and practice are combined.
Nothing works and no one knows why.
8
9. Induction vs. Deduction
• Induction is the development of argument from the
specific to the general (or theoretical)
• Deduction is the development of argument from the
general to the specific
9
10. Key Definitions 2
• What is RESEARCH METHODOLOGY?
– body of knowledge which attempts to explain/understand
(and hence develop structure for) ‘how research is done’
– the various steps that are generally adopted by a
researcher in studying his research problem (method)
together with the associated logic (what and why)
• What is RESEARCH METHOD?
– the specific process or steps followed by researchers in
undertaking research (experimental design, data collection,
etc)
• What is RESEARCH DESIGN?
– the overview or plan of the actual steps (c.f. the architect’s
drawings of a house vs. the builders steps)
10
11. Key Definitions 3
• What is ONTOLOGY?
– the (philosophical) study of the categories of being (reality)
and the relationships between them (ontology of NSI or
knowledge)
• What is EPISTEMOLOGY?
– the philosophical study of the nature and scope of
knowledge (e.g. traditional vs. scientific)
• What is TELEOLOGY?
– the notion of root cause or objectives; it is an account of a
given activity’s or object’s purpose OR a definition of an
object or activity based on its purpose (e.g. a car is a form
of transport)
11
13. Ontologies
• The dominant ontological claims:
– positivism; that there exists are single reality which is
constant in time and independent of human experience or
the observer
– constructivism; that there exist multiple realities
dependant on the observer (in the extreme form there is
no such notion as an objective reality)
– critical realism; that there multiple versions of the
‘knowledge of reality’ but only a single reality
13
14. Philosophical Origins of the
Bifurcation
• Ludwig Wittgenstein (1889-1951); “scientific
evidence”
– all knowledge claims must be verifiable in experience
independent of the observer
– founder of logical positivism
• Martin Heidegger (1889-1976); “being in the world”
– research cannot be conducted independent of the
observer
– founder of constructivism
14
15. Assumptions of the Experimental
Scientific Method (Positivist)
• A belief that there is some kind of ORDER which will
be revealed (come to understand) through research
• External reality exists which is a shared or public
reality
• Human perception and intellect is reliable (our
senses can record and measure)
• Parsimony or simplicity is the ultimate aim
• Generality is possible; we can generalise from the
particular to the world at large
15
Cohen and Manion 2000
16. A Comparison of Epistemological
Paradigms
Positivist Constructivist
Reality is single, objective and
apart from the observer
Reality is subjective and multiple
Quantitative data derived from
experiment
Qualitative data derived from
observation
Reliability is most important
(repeatable results)
Validity is important (improved by
triangulation)
Deductive Inductive
Location is artificial; all variables
held constant except the
independent variable
Location is natural; not possible
to control any variables
Mainly experimental, preferably
with control
Type of research includes
ethnographic, participant
observation, case studies
16
17. The Praying Mantis
• Observation: in certain conditions (laboratory), the
female mantis will eat her mate
• Interpretation:
– male researchers: the praying mantis, with its forelegs
folded as if in prayer, may look pious, but its mating ritual
is truly a macabre affair. Once the smaller male is attached
to the female's body, she decapitates him, but he
continues the act of conjugation for several more days
before he dies and is eaten by his voracious mate.
17
18. Female Researchers
• Yes, the female praying mantis does sometimes eat her mate.
In fact, male mantises will often offer themselves up as food to
the female during the mating process, and from a biological
standpoint this action makes sense. There's no point to mating
with a female who might die from a lack of food before she can
lay her eggs and pass the father's genes onto the next
generation.
• In some instances, she'll even behead the poor chap before
they've consummated their relationship. As it turns out, a male
mantid is an even better lover when his brain, which controls
inhibition, is detached from his abdominal ganglion, which
controls the actual act of copulation. But most instances of
sexual suicide in mantids occur in the confines of a laboratory
setting. In the wild, scientists believe the male partner gets
eaten less than 30% of the time.
18
19. Several Types of Research Design
• Qualitative vs quantitative vs mixed methods (see
Lecture 2)
• Types of designs
– Experimental
– Surveys
– Case studies
– Ethnographic studies
– Evaluation research
– Participatory action research (actually a separate
paradigm)
19
20. Essential Attributes in Research
• Marais defines three necessary dimensions of
research:
– Teleological (describe, explore, explain/understand)
– Constituent (conceptualisation, hypothesis, observation
and communication)
– Epistemic (internal and external validity, reliability,
‘replicability’, objectivity)
• Most research can be judged on the extent to which
the three dimensions have been satisfied (was the
objective clear; has the due process been follow; is
the knowledge of a suitable quality?)

Studies. The Electronic Journal of Business Research
Methods, 10(2), pp 64-76.
21
22. Epistemic Attributes (Positivist)
• Internal Validity: the degree to which the changes in
the dependent variable are indeed due to the
independent variable (is the relationship causal?)
• External Validity: the extent to which the results are
generally applicable (outside the sample population)
• Reliability: the extent to which the research finding
can be repeated by the same researcher/experiment
• Replicability: the extent to which the findings can be
repeated by another researcher (also objectivity)

23. Attributes (Modern)
Traditional construct Underlying issue Replace with
Internal validity Truth value Credibility
External validity Applicability Transferability
Reliability Consistency Dependability
Objectivity Neutrality Confirmability

24. Academic Research vs. Management
Study
Aspect Academic Research Management Study
External
validity
The results can be applied more
widely than the unit of research
(company or individuals)
The results are only valid to the
specific company or individual
Theory Builds new theory or tests existing
theory
Applies theory but at a
simplistic level
Source of
background
knowledge
Mostly recent peer-reviewed
literature
Mostly trade articles and other
management studies
Teleology Seeks causative relationship Focussed on improvements and
results
Methodology Seeks novelty (insights) Replication of proven formulas
for success

25. Class Work
• Fill in three dimensions of the line below
25
Scientific
Knowledge
Faith
Evidence is important
Sentiment (how it makes you
feel) is important
Objectivity is important
26. Test Yourself
• There appear to be two opposing epistemological positions on the
relationship or interdependence between science, society and the
individual:
– relativism which situates science as merely one socially constructed way
of knowing among others of equal validity
– realism, which accords science a greater status as a universally true body
of knowledge.
• Realism has been cast as ignoring the influence of social factors on
science. Relativism has been pronounced to be impractical and
ignorant of the existence of many fundamental laws which are
observable independent of the observer.
• Explain the debate between the two epistemological viewpoints, why
relativism is considered impractical and suggest how a compromise
may be possible.
