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.

HISTORY OF COMPUTER
The computer as we know it today had its beginning
with a 19th century English mathematics professor
name Charles Babbage.
He designed the Analytical
Engine and this was the
Design that is the basic
framework of the computer.
Each generation lasted for a
certain period of time, and
each gave us either a new
and improved computer or
an improvement to the existing computer.
First Generation (1940-1956) Vacuum
Tubes:
The first computers used vacuum tubes for
circuitry and magnetic drums for memory, and
were often enormous, taking up entire rooms.
3. Computerprogramming1st

3
They were very expensive to operate and in
addition to using a great
Deal of electricity, the first
computers generated a lot
of heat, which was often
the cause of malfunctions
EXAMPLE
The UNIVAC and ENIAC
computers are examples of
first-generation computing
devices.
Second Generation (1956-1963)
Transistors:
Transistors replace vacuum tubes and ushered in
the second generation of computers. The
transistor was invented in 1947 but did not see
widespread use in computers until the late 1950s.
The transistor was far superior to the vacuum
tube, allowing computers to become smaller,
faster, cheaper, more energy-efficient and more
4. Computerprogramming1st

4
reliable than their first-generation computers.
Second-generation
computers still relied
on punched cards
for input and
printouts for output.
Second-generation
computers moved from
cryptic binary machine
language to symbolic, or
assembly.
EXAMPLES:
In the early 1960s,
the IBM 1401 and
Honeywell 400 were
examples
Third Generation(1964 -1971) Integrated
Circuits:
The development of the integrated circuit was the
hallmark of the third generation of computers.
5. Computerprogramming1st
assignment
5
Transistors were miniaturized and placed on silicon
chips, called semiconductors, which drastically
increased the speed
and efficiency of
computers.
Instead of punched
cards and printouts,
users interacted with
third generation
computers through
keyboards and
monitors and interfaced with an operating system.
Computers for the first time became accessible to a
mass audience because they were smaller and
cheaper than their predecessors.
EXAMPLE:
The LILLIAC IV is an example of a third generation
computer.
6. Computerprogramming1st

Fourth Generation (1971-Present)
Microprocessors:
The microprocessor brought the fourth
generation of computers, as thousands of
integrated circuits were built onto a single silicon
chip. What in the first generation filled an entire
room could now fit in the palm of the hand. The
Intel 4004 chip, developed in 1971, located all the
components of the computer—from the central
processing unit and memory to input/output
controls—on a single chip.
Microprocessors also moved out of the realm of
desktop computers and into many areas of life as
more and more everyday products began to use
microprocessors.
7. Computerprogramming1st

As these small computers became more powerful,
they could be linked together to form networks.
EXAPLES:
This has resulted in new classes of machines
such as personal computers
Fifth Generation (Present and Beyond)
Artificial Intelligence:
Fifth generation computing devices, based on
artificial intelligence, are still in development,
though there are some applications, such as voice
recognition, that are being used today. The use of
parallel processing
and superconductors is
helping to make
artificial intelligence a
reality. Quantum
computation and
molecular and
8. Computerprogramming1st

nanotechnology will radically change the face of
computers in years to come. The goal of fifth-
generation computing is to develop devices that
respond to natural language input and are
capable of learning and self-organization.
TYPES OF COMPUTER
Computers can be broadly classified by their speed
and computing power.
The main four types are:
I. Supercomputer
II. Mainframe Computer
III. Minicomputer
IV. Microcomputer

Minicomputer:
Minicomputers are used by small businesses &
firms. Minicomputers are also called as “Midrange
Computers”. These are small machines and can be
accommodated on a disk with not as processing and
data storage capabilities as super-computers &
Mainframes. These computers are not designed for
a single user. Individual departments of a large
company or organizations use
Minicomputers for specific purposes.
