In the Gradient Descent algorithm, we are more likely to reach the global minimum, if the learning rate is selected to be a large value.
a. True
b. False
Answer:
false i think.
Explanation:
Gradient Descent is more likely to reach a local minima. because starting at different points and just in general having a different starting point, will lead us to a different local minimum( aka the lowest point closest to the starting point). if alpha(the learning rate) is too large, gradient descent may fail to converge and may even diverge.

5. Write the function that would count the number of
occurrences of 9 in the entire range
(3 marks)
Answer:
I love Microsoft Excel!
Explanation:
2 - The function that would find the average of a particular range is =AVERAGE(). This is used to find the average of something by calculating the arithmetic mean (or just "mean").
3 - The function that would find the total values within a particular range---or in this case, Column J---you would use the =SUM() function. This will add up all of the values in the range you selected. An example could be that Column X has the values of 5, 6, 12, 45, 3. =SUM(X1:X5) = 71.
4 - The function that would count all values is defined as =COUNT(). An example would be =COUNT(A1:A10).
5 - The function that would count the number of occurrences within a particular range is defined as =COUNTIF(). Within the parentheses, you would put the range of data that you are working with. Then, in quotations, you would put the name or value that you are trying to find.
In your case, it would be =COUNTIF(range,"9") ((I put range in there since I do not know what your range is as it is not defined within the context of this question))

Dr. Watson has been kidnaped! Sherlock Holmes was contacted by the kidnapper for ransom. Moments later he received a message from Dr. Watson's phone. The message contained three random strings. Sherlock being Sherlock, was able to deduce immediately that Dr. Watson was trying to give a hint about his location. He figured out that the longest common subsequence between the 3 words is the location. But since it was too easy for him, he got bored and asked you to find out what the actual location is. Your task is to find the longest common subsequence from the 3 given strings before it is too late. A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements. For instance, given a sequence "drew"; "d", "w", "de", "drw", "drew" are all examples of valid subsequences (there are also others), while "er", "wdre" are not. Design a dynamic programming algorithm which takes three input sequences X, Y, and Z, of lengths m, n, and p, respectively, and returns their longest common subsequence. For full marks your algorithm should run in (mnp) time. Note that W is a common subsequence of X, Y, and Z if and only if W is a subsequence of X, W is a subsequence of Y, and W is a subsequence of Z.

Describe the set of subproblems that your dynamic programming algorithm will consider.

which rendering algorithm must be applied if a realistic rendering of the scene is required
Answer:
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term "rendering" is analogous to the concept of an artist's impression of a scene. The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output.

A variety of rendering techniques applied to a single 3D scene

An image created by using POV-Ray 3.6
Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the graphics pipeline, giving models and animation their final appearance. With the increasing sophistication of computer graphics since the 1970s, it has become a more distinct subject.
Rendering has uses in architecture, video games, simulators, movie and TV visual effects, and design visualization, each employing a different balance of features and techniques. A wide variety of renderers are available for use. Some are integrated into larger modeling and animation packages, some are stand-alone, and some are free open-source projects. On the inside, a renderer is a carefully engineered program based on multiple disciplines, including light physics, visual perception, mathematics, and software development.
Though the technical details of rendering methods vary, the general challenges to overcome in producing a 2D image on a screen from a 3D representation stored in a scene file are handled by the graphics pipeline in a rendering device such as a GPU. A GPU is a purpose-built device that assists a CPU in performing complex rendering calculations. If a scene is to look relatively realistic and predictable under virtual lighting, the rendering software must solve the rendering equation. The rendering equation doesn't account for all lighting phenomena, but instead acts as a general lighting model for computer-generated imagery.
In the case of 3D graphics, scenes can be pre-rendered or generated in realtime. Pre-rendering is a slow, computationally intensive process that is typically used for movie creation, where scenes can be generated ahead of time, while real-time rendering is often done for 3D video games and other applications that must dynamically create scenes. 3D hardware accelerators can improve realtime rendering performance.

During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
1. Based on Scenario A, the packets should be encapsulated in multiple frames to minimize the re-transmission overhead.
This is because there will be the need to re-transmit the packets because the network environment is not reliable and accurate. Therefore, a single frame may be too costly when the need for re-transmission arises.
2. Based on Scenario B, the packets should be encapsulated in a single frame because of the high level of network reliability and accuracy.
There will not be further need to re-transmit the packets in a highly reliable and accurate network environment. This environment makes a single frame better.
Encapsulation involves the process of wrapping code and data together within a class so that data is protected and access to code is restricted.
With encapsulation, each layer:
provides a service to the layer above itcommunicates with a corresponding receiving nodeThus, in a reliable and accurate network environment, single frames should be used to enhance transmission and minimize re-transmission overhead.

Alice and Bob are unknown to each other. Alice wants to send an encrypted message to Bob. So it chooses a KDC which is known to both Alice and Bob (protocol in page 338). Alice and KDC have A5 (hexa) as a shared key. Bob and KDC have 4B (hexa) as a shared key. Alice sends a request to KDC to generate a session key so it can communicate with Bob. KDC generates 56(hexa) as a session key. Alice intends to send 13 (hexa) as a message to Bob. For simplicity assume that the encryption and decryption operations are simply XOR operation of the key with the message. Answer the following.
