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.
2. Importance
We read a lot of technical article of research and technology. We
use various electronics gadgets in our daily routine life which are
less with smart hardware and software even a good mechanical
architecture.
As a general gadget user, you do never waste your time to know
its internal working that how does it works? But you know well,
how to use it. Any single malfunction or bug of your gadgets
leads to you in frustration.
To avoid such conditions, manufacturing companies try to make
a best product for their customer. So that frustration level could
not meet to user.
3. Why it is required?
Test and measurement saves from heavy losses like
• Extra cost
• Extra labor
• Good will of industry that is priceless
Test and measurement of design provides
• Confidence
• Design correction
• Value in market
• Reduce risk
4. Reliability and validity
Reliability
• The degree to which at test or measure produce the same
scores or results when applied in the same circumstances
• It refers to how dependably or consistently a test measures a
characteristic.
If a person takes the test again, will he or she get a similar test
score, or a much different score? A test that yields similar scores
for a person who repeats the test is said to measure a
characteristic reliably.
5. Validity
• Validity also describes the degree to which you can
make specific conclusions or predictions about people
based on their test scores. In other words, it indicates
the usefulness of the test.
• Validity refers to what characteristic the test
measures and how well the test measures that
characteristic.
7. How to ensure to meet Reliability and
validity of product
• A product, when it’s designed has been completed and produced
on testing table. An engineer must analyze its performance and
design attributes precisely.
• Don’t hurry while testing and measurement.
• Any malfunction of equipment and human error could lead to
mislead and doubt.
• To ensure recorded date of calibration of equipment
• Product should always be measured or tested more than once.
• Taking multiple step of measurement makes repeatability and
reliability of the product which is major milestone for a company.
• Keep specs tight for pre production so that it could compensate
production.
8. Why testing is required?
Testing is really required
• To point out the defects and errors those were made during
the development phase.
• To ensure how much design is correct
• To make sure reliability of the product
• To know, how much work and effort is required to make
perfect product
• To give feedback to the designer
• To get time estimation to complete the product.
9. What to do?
• Test and measurement is the Basic requirement for
developing a product.
• Industries must invest at the setup of test and measurement
of the product whether it is electronic, software or
mechanical.
• Industry must focus on testing and measurement of the
product rather than its outer finishing.
• Make prototype first and repeat at least three numbers.
• Test the performance of prototype product as per designer
specs
• Tweak and modify for the best result
• Adopt the future need at least 5 year ahead into your product
10. What needs to control?
• Manage and controlling the accuracy of measuring equipment
is an essential component, periodic calibration of measuring
instruments
• Manage revisions of the products
• Don’t change vendors repeatedly unless there is major
reason.
• Control workmanship and quality of the material.
