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.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

1. Resistors & Colour Coding
Objectives:
• What is a Resistor ?
• Types of Resistor
• Parameters affecting resistance value
• Determine the resistance of a resistor using
the color code.
• Discuss how exceeding its power rating can
cause damage to a resistor.
• Discuss the use of a variable resistor as a
potentiometer.
2. What is Resistance ???
• the action of opposing something that you disapprove or
disagree with; "he encountered a general feeling of resistance
from many citizens"; "despite opposition from the
newspapers he went ahead"
• any mechanical force that tends to retard or oppose motion
• electric resistance: a material's opposition to the flow of
electric current; measured in ohms
• the military action of resisting the enemy's advance; "the
enemy offered little resistance"
• immunity: (medicine) the condition in which an organism can
resist disease
3. Types of Resistors
Resistors are made in many forms but all
belong in either of two groups:
Fixed resistors – are made of metal films, high-
resistance wire or carbon composition
Variable resistors – have a terminal resistance
that can be varied by turning a dial, knob, screw, or
anything else appropriate for the application
4. Resistors
• Fixed resistors have only one ohmic value, which cannot
be changed or adjusted. One type of fixed resistor is the
composition carbon resistor.
5. Resistors
• Metal film resistors are another type of fixed resistor.
These resistors are superior to carbon resistors because
their ohmic value does not change with age and they
have improved tolerance.
6. Resistors
• Carbon resistors are very popular for most applications
because they are inexpensive and readily available in
standard sizes and wattages.
½ Watt 1 Watt 2 Watt
7. Resistors
• Wire-wound resistors are fixed resistors that are made
by winding a piece of resistive wire around a ceramic
core. These are used when a high power rating is
required.
9. Types of Resistors
Variable resistors can have two or three
terminals. Most have three.
Variable resistors are classified as a rheostat
or a potentiometer, depending upon the
application.
Rheostat: Two- or three-terminal device used as
a variable resistor
Potentiometer: Three-terminal device used for
controlling potential levels
10. Resistors
• Variable resistors can change their value over a specific
range. A potentiometer is a variable resistor with three
terminals. A rheostat has only two terminals.
11. Types of Resistors
Most potentiometers have
three terminals as shown.
The knob, dial or screw in the
center of the housing controls
the motion of a contact that
can move along the resistive
element connected between
the outer terminals.
The contact is connected to
the center terminal,
establishing a resistance from a
movable contact to each outer
terminal.
12. Types of Resistors
The resistance between the
outside terminals a and c is always
fixed at the full rated value of the
potentiometer, regardless of the
position of the wiper arm (b).
The resistance between the wiper
arm and either outside terminal
can be varied from a minimum of
0 to a maximum value equal to
the full rated value of the
potentiometer.
The sum of the resistances
between the wiper arm and each
outside terminal will equal the full
rated resistance of the
potentiometer
13. Factors affecting Resistance
The resistance of any material with a uniform
cross-sectional area is determined by the
following factors:
Material
Length
Cross-sectional Area
Temperature
14. Resistance: Circular Wires
The higher the resistivity of a conductor, the
higher its resistance.
The longer the length of a conductor, the
higher its resistance.
The lower the cross-sectional area of a
conductor, the higher its resistance.
The higher the temperature of a conductor,
the higher its resistance
15. Resistors
• The resistor color code can be used to determine the
resistor’s ohmic value and tolerance.
18. Resistors
• Review:
1. Resistors are used in two main applications: as
voltage dividers and to limit the flow of current
in a circuit.
2. The value of fixed resistors cannot be changed.
3. There are several types of fixed resistors such
as composition carbon, metal film, and wire-
wound.
19. Resistors
• Review:
1. Carbon resistors change their resistance with age
or if overheated.
2. Metal film resistors never change their value, but
are more expensive than carbon resistors.
3. The advantage of wire-wound resistors is their
high power ratings.
20. Resistors
• Review:
1. Resistors often have bands of color to indicate
their resistance value and tolerance.
2. Resistors are produced in standard values. The
number of values between 0 and 100 Ω is
determined by the tolerance.
21. Resistors
• Review:
1. Variable resistors can change their value
within the limit of their full value.
10. A potentiometer is a variable resistor used as
a voltage divider.
22. Resistors
• Resistors are commonly used to perform two functions
in a circuit.
• The first use is to limit the flow of current in a circuit.
I = E / R
I = 15 V / 30 Ω
I = 0.5 A
23. Resistors
• Resistors are commonly used to perform two functions in
a circuit.
• The second use is to produce a voltage divider.
A to B = 1.5 V
A to C = 7.5 V
A to D = 17.5 V
B to C = 6 V
B to D = 16 V
C to D = 10 V
