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.

14. Forced draft (FD) fan
FD fan takes the air present in the outside environment and directs it into the furnace/boiler. As a result a positive p
Created and that contributes to smooth completion of combustion process.
FD fans are fixed and close to the furnace.
The FD fan ensures that the volume of air that is in the system are consistently balanced. This balance is mandatory
balanced combustion.
15. Induced draft(ID) fan
The ID fans are usually curved in the backward direction . This particular design is necessary for fans that have to han
Levels of pressure.
There is an accumulation of hot flue gases in furnace and boilers . The ID fan operate in such a way that these gases g
Out from the system to the atmosphere.
These fans achieve that by generating negative pressure with in the system.
The boiler system’s outlet is the precise point where id fan present.
16. Primary air (PA) fan
The major objective of the PA fan is to ensure that the coal that has been pulverized is properly transported into
the furnace .
The PA fans operate to generate extreme pressure, which is needed to thrust the coal particles and air towards the f
These fans assist in separating the particles of fuel from one another and thus making sure that combustion gets co
devoid of any hindrances.
17. Secondaryair (SA)fan
The chief function of the SA fan is to support the PA fan.
Whenever the situation arises ,the secondary air fans bring about a rise in amount of air flow. Both prevents fuel wa
and enhance the overall efficiency of the combustion process.
Presence of SA fan makes certain that added air is promptly supplied to the system. With that ,there will not be any
