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.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

6. Stack is a special region of computer's memory that stores temporary
variables created by each function (including the main() function).The stack is a
"FILO" (first in, last out) data structure, that is managed and optimized by the
CPU quite closely. Every time a function declares a new variable, it is "pushed"
onto the stack.Then every time a function exits, all of the variables pushed
onto the stack by that function, are freed (that is to say, they are deleted).
Once a stack variable is freed, that region of memory becomes available for
other stack variables.
7. the stack grows and shrinks as functions push and pop local
variables
there is no need to manage the memory yourself, variables
are allocated and freed automatically
the stack has size limits
stack variables only exist while the function that created
them, is running
8. main()
{
Int a=10,b=20,c;
c=sum(a , b);
}
int sum(int a , int b)
{
int c;
c=a+b;
return c;
}
STACK
Main()
a=10
b=20
c ;
sum()
a =10
b=20
C=30
9. The heap is a region of computer's memory that is not
managed automatically , and is not as tightly managed by
the CPU. It is a more region of memory .
To allocate memory on the heap, you must
use malloc() or calloc(), which are built-in C functions.
Once you have allocated memory on the heap, you are
responsible for using free() to deallocate that memory
once you don't need it any more. If you fail to do this, your
program will have what is known as a memory leak.That
is, memory on the heap will still be set aside (and won't be
available to other processes).
10. malloc() Allocates requested size of bytes and
returns a pointer first byte of allocated space
calloc() Allocates space for an array
elements, initializes to zero and then returns a
pointer to memory
free() deallocate the previously allocated
space
realloc() Change the size of previously
allocated space
11. malloc()
Syntax
malloc(size in bytes);
This function allocates ‘size’ byte of memory and returns a pointer to
the first byte or NULL if there is some kind of error
But we need a pointer to point to the allocated space in heap
int *p; p=malloc(2);
12. int *p;
p=malloc(2); //allocates 2 bytes of memory
p=malloc(sizeof(int)); //sizeof() returns size of any data type
so here it will be malloc(2)
p=(int *)malloc(2); //malloc always return void * pointer .
So you may type cast it into
any data type.
but it is unnecessary as the compiler
does it
for us
p=(int *)malloc (sizeof(int)); //allocates 2 bytes of memory
13. Calloc() stands for "contiguous allocation”
Allocates multiple blocks of memory each of same size and sets all
bytes to zero
Syntax
calloc(number of elements , size in bytes);
we need a pointer to point to the allocated space in heap
14. int *p;
p=calloc(2,2); //allocates 2 block of 2 bytes memory
p=calloc(3,sizeof(int)); //sizeof() returns size of any data type
so here it will be calloc(3,2)
p=(int *)calloc(2,10); //calloc always return void * pointer .
So you may type cast it into any data type.
but it is unnecessary as the compiler does it
for us
p=(int *)calloc (3,sizeof(int)); //allocates 3 block of 2 bytes

15. MALLOC()
• Allocates "size" bytes of memory.
• The contents of
allocated memory are not
changed. i.e., the memory may
contains garbage values.
• returns void pointer (void *). If
the allocation succeeds, a pointer
to the block of memory is returned
CALLOC()
• Allocates
a region of memory large
enough to hold "n elements" of
"size" bytes each.
• The allocated region is
initialized to zero.
• returns void pointer (void *). If
the allocation succeeds, a
pointer to the block of
memory is returned.
16. realloc( pointer name , new size );
It will realloc the size of memory
free( pointer name );
De allocate the memory
