Answer:
First-order method: Gradient Descent
Gradient descent is a first-order optimization algorithm that iteratively updates the parameters of a model by moving in the direction of the negative gradient of the loss function.
The algorithm starts with an initial set of parameters and then at each iteration, it computes the gradient of the loss function with respect to the parameters and updates the parameters by taking a step in the opposite direction of the gradient. This process is repeated until the parameters converge to a minimum or maximum of the loss function.
Accelerated first-order method: Nesterov Accelerated Gradient Descent (NAG)
Nesterov Accelerated Gradient Descent (NAG) is an accelerated first-order optimization algorithm that improves upon the vanilla gradient descent by adding a momentum term.
The algorithm starts with an initial set of parameters and at each iteration, it computes the gradient of the loss function and updates the parameters by taking a step in the direction of the negative gradient with a momentum term.
The momentum term helps to smooth out the oscillations that can occur in the gradient descent algorithm and allows the algorithm to converge faster to a minimum or maximum of the loss function.
Second-order method: Newton-Raphson method
Newton-Raphson method is a second-order optimization algorithm that improves upon the first-order methods by taking into account the curvature of the loss function.
The algorithm starts with an initial set of parameters and at each iteration, it computes the gradient of the loss function as well as the Hessian matrix (the matrix of second-order partial derivatives of the loss function with respect to the parameters) and updates the parameters by taking a step in the direction of the negative of the inverse of the Hessian multiplied by the gradient.
explain the difference between external, internal, and conceptual schemas. how are these different schema layers related to the concepts of logical and physical data independence?
Data abstraction typically occurs at three schema levels: Internal Level: Actual PHYSICAL access routes and storage architecture. Conceptual or Logical Level: Database limitations and structure as a whole external or viewpoint level.
How do these many layers of the schema relate to the idea of logical and physical data independence?All of the schemas are logical, and the actual data is kept on the disk in bit format. Changes to the physical data can be made without having an effect on the schema or logical data if you have physical data independence.

what is the default access specifier for data members or member functions declared within a class without any specifier, in c ?
Answer:
nothing
Explanation:
C is a programming language that was developed in the early 1970s, it doesn't have built-in support for object-oriented programming concepts like classes, inheritance, and access specifiers. Struct and union are used for grouping data and doesn't have the same functionality as classes in C++. It doesn't have access specifiers such as public and private. The code written in C is still widely used today, but if you want to use object-oriented programming and access specifiers, you will need to use a language like C++ or Java.
Go to the Grid Columns Style section. Create a style rule to float every div element whose class name begins with column on the left. Create style rules for div elements belonging to the following classes:. Column100,. Column50,. Column33,. Column67,. Column25,. Column75,. Column20,. Column40,. Column60, and. Column80 so that the width of each column is a percent equal to the size value. For example, div elements belonging to the. Column100 class should have widths of 100%,. Column50 should have widths of 50%, and so forth. Note: Use 33. 33% for. Column33 and 66. 67% for. Column67
A grid column is a vertical track and the area between two vertical grid lines in a CSS Grid Layout. The grid-template-columns property, as well as the abbreviated grid and grid-template properties, define it.
In CSS grid, how can I create three columns?Through the use of grid-template-columns: If you type repeat(3, 1fr) on a grid container, you will get a layout with 3 columns that are all the same width. Grid layout will automatically make all the objects in each row the same height. The solution is worth saving.
I need to set the grid's columns and rows.To begin, you must establish a container element, set the column and row sizes using grid-template-columns and grid-template-rows, and then add its child elements to the grid with grid-column and grid-row.

This code is very concise and efficient in swapping the initial values of the three variables.
Write a piece of code that writes the initial value of p in q, the initial value of q in r, and the initial value of r in p?The following code can be used to write the initial value of p in q, the initial value of q in r, and the initial value of r in p:p, q, r = Person(), Person(), Person()
p.__dict__, q.__dict__, r.__dict__ = q.__dict__, r.__dict__, p.__dict__
This code takes advantage of the fact that the Person class has a __dict__ attribute, which is a dictionary that contains all the instance variables of the object.The code simply swaps the values of the __dict__ attributes of the three Person objects, which allows us to write the initial value of p in q, the initial value of q in r, and the initial value of r in p.This code is quite compact and is easy to read and understand, making it an ideal choice for solving this problem.p.name = q.name;
q.name = r.name;
r.name = p.name;
The code first stores the initial value of p in q, then the initial value of q in r, and finally the initial value of r in p. This effectively swaps the initial values of the three variables and ensures that each variable contains the initial value of the other two.This code also takes advantage of the fact that the variables are of type person, as it uses the name property of the person objects to swap values.

It is designed to provide connection-oriented communication between two devices, with data being sent in a reliable and orderly fashion. To ensure reliability, TCP uses a checksum algorithm to detect data corruption, and provides flow control to prevent data packets from being lost. It also provides congestion control, which helps the network avoid packet loss due to network congestion. In addition, it allows applications to request data in small chunks, providing better overall performance when data must be sent over multiple connections. TCP is an important protocol used in many applications, including web browsing, file transfer, and email.

(c) Clock B: When clock A reads 380 s, clock B will read about 285.3 s. In the earliest occasion, clock B reads 25s and clock A reads 38s. This gives us a ratio of 25:38. We can use this ratio to calculate the time on clock B when clock A reads 380s. 380s × (25/38) = 285.3 s.
(d) Clock B: When clock C reads 11s, clock B will read about 8.5s. In the earliest occasion, clock B reads 25s and clock C reads 92s. This gives us a ratio of 25:92. We can use this ratio to calculate the time on clock B when clock C reads 11s. 11s × (25/92) = 8.5s.

When the PT-109 American patrol boat, under the command of Lieutenant John F. Kennedy, was sunk by a Japanese destroyer, a message was received at an Australian wireless station in Playfair code: KXJEY UREBE ZWEHE WRYTU HEYFS KREHE GOYFI WTTTU OLKSY CAJPO BOTEI ZONTX BYBNT GONEY CUZWR GDSON SXBOU YWRHE BAAHY USEDQ The key was royal new zealand navy. Decrypt the message. Translate TT into tt
Key = ROYALNEWZEALANDNAVY. Initially we represent the given key in a 5x5 matrix form without repetition of letters. After that, we fill the matrix with remaining left over letters in A-Z in alphabetical order. Remember that I/J has to repsented in the same box.The matrix looks like:
Now we take two letters at a time and follow the below rules to decrpyt the given message:
1) If the same letter appears twice, represent the letter one time as it is. For example, TT will be decrypted as T.
2) If two letters appear on the same row, replace each letter by the letter which is immediately to the left of it.
3) If two letters appear on the same column, replace each letter by the letter which is immediately to the above of it.
4) Otherwise, form a rectangle for which the two letters are at two opposite corners. Then replace each letter with the letter that forms other corner of the rectangle in the same row.

Take two letters at a time and decrypt using the above rules.Take KX and check them in the matrix. We can see that they form a rectangle. So replace K and X with the letters that form the corners of the rectangle i.e P and T.
Now take J and E. We can see that J and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace J with B and E with O.
Take Y and U. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace Y with A and U with T.
Take R and E. We can see that they are forming a rectangle. So replace them with letters that form other corners of the rectangle. Replace R with O and E with N.
Take B and E. We can see that B and E are located on the same column. So replace each letter with the letter that is immediately above it. Replace B with E and E with O.
Take Z and W. We can see that Z and W are located on the same row. So replace each letter with the letter that is immediately to the left of it. Replace Z with W and W with E.
Repeat the above process until all the letters are decrypted. Then form a meaningful sentence out of it. Therefore, the given message after decryption is:
