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.

floating barge, fitted with long support legs that can be
raised or lowered independently of each other.
The rig is towed onto location by a supply vessel with
its legs elevated and the barge section floating on the
water.
9. SEMI SUBMERSIBLE
Semi-submersible rigs is a floating vessel that is
supported primarily on large pontoon structures
submerged below the sea surface. The operating
decks
are typically elevated 100 feet above the pontoons
on
large steel columns.
10. DRILL SHIPS
It is a maritime vessel that has been
fitted with drilling apparatus. In order to drill, a Marine
Riser is lowered to the seabed with a Blow Out Preventer
(BOP) at the bottom.
• Applicable depths: Normally able to drill up to 5000m.
Recent, modern ones can up to 7000m.
• The function of DSs can also be performed by Semi-
submersibles, jackup barges, barges, or platform rigs.
RECENT EXAMPLES: 210m IODP vessel D/V Chiyu,
Japan, that can drill 7000m below the sea bed.
11. TENSION LEG PLATFORM(TLP)
• Brief description: TLPs consist of floating rigs tethered
to the seabed in a manner that eliminates most vertical
movement of the structure.
• Applicable depths: Used in water depths up to about
2,000m.
• Types: Conventional TLP - 4-column design which looks
similar to a semi-submersible. They are relatively low cost,
used in water depths between 200 and 1,100 m.
• Additional use: Mini TLPs can also be used as utility,
satellite or early production platforms for larger deepwater
discoveries.
