Artificial Intelligence Applied to Big Data: Case Study
One notable case study where Artificial Intelligence (AI) is applied as a solution to a big data problem is the use of AI in predictive analytics for credit risk assessment in the banking industry. This case study is highly relevant to my study program in finance and data analytics. The reference for this case study is as follows:
Reference:
Author(s): Lin, X., & Chen, S.
Title: "Credit risk assessment with an effective hybrid model based on data preprocessing and machine learning algorithms."
Journal: Journal of Ambient Intelligence and Humanized Computing.
Year: 2018.
Volume: 9.
Issue: 6.
Pages: 1985-1995.
DOI: 10.1007/s12652-018-0777-y.
The study conducted by Lin and Chen focuses on credit risk assessment, an essential task in the banking industry. Assessing the creditworthiness of borrowers accurately is crucial to minimize the risks associated with lending. In this case study, the authors propose an effective hybrid model that combines data preprocessing techniques and machine learning algorithms to improve credit risk assessment.
To handle the vast amount of data involved in credit risk assessment, big data techniques are employed. The data preprocessing stage involves cleaning, integrating, and transforming the data to ensure its quality and compatibility for further analysis. This step is crucial as it helps to eliminate noise, inconsistencies, and missing values from the raw data.
After the data preprocessing, the authors utilize machine learning algorithms to train a predictive model for credit risk assessment. The study employs several popular machine learning algorithms, including Support Vector Machines (SVM), Random Forest (RF), and Artificial Neural Networks (ANN). These algorithms are trained using the preprocessed data to learn patterns and relationships between various credit-related factors and the risk of default.
The predictive model developed through the hybrid approach provides accurate and reliable credit risk assessment results. By utilizing AI techniques and analyzing big data, the model can identify patterns and detect potential risks more effectively compared to traditional methods. The authors evaluate the performance of the model using real credit datasets, demonstrating its superiority in predicting credit risk and reducing the occurrence of false positives and false negatives.
This case study highlights the significance of AI and big data analytics in improving credit risk assessment. By leveraging advanced techniques such as data preprocessing and machine learning algorithms, banks and financial institutions can make more informed lending decisions and mitigate the risks associated with credit defaults.
In conclusion, the research conducted by Lin and Chen showcases the application of AI in solving a big data problem related to credit risk assessment. The proposed hybrid model demonstrates the effectiveness of combining data preprocessing and machine learning algorithms to enhance the accuracy of credit risk assessment in the banking industry. This study serves as a valuable reference for understanding the practical implementation of AI in the field of finance and data analytics.

Answers
Answer:
Retirement.
Explanation:
When a laptop gets recycled by an e-waste recycling company once it can't be used anymore. This belongs to the retirement stage of the hardware lifecycle.
Hardware lifecycle can be defined as the management of the total or overall useful life of an equipment or device, so as to maximize or enhance the benefits to be derived from its use.
The retirement stage of a hardware represents the stage where the hardware has reached the end of its life-cycle and as such can not be used to perform the task for which it was designed. It is at the retirement stage, that hardwares are written off as scraps and are to be replaced by another because they can't be used anymore, as well as disposal for recycling purposes.

how to move installed programs to another drive windows 7
Answers
To move installed programs to another drive in Windows 7, you can follow these general steps:
a) Create a backup
b) Change the installation directory
c) Copy program files
d) Test the program
Create a backup: Before making any changes, it's always recommended to create a backup of your important files and data. This will ensure that you have a copy in case anything goes wrong during the process.
Uninstall the program (optional): If the program you want to move has an uninstaller, you can choose to uninstall it first. This will remove the program from your current drive and allow you to reinstall it on the new drive later.
Change the installation directory: During the installation process of the program, you can usually choose the installation directory. Select the new drive as the installation location. If the program is already installed, you may need to reinstall it and specify the new drive as the installation directory.
Copy program files: If the program doesn't have an uninstaller or you want to keep its current configuration, you can manually copy the program files from the current drive to the new drive. Here's how:
a. Go to the current installation directory of the program (typically located in "C:\Program Files" or "C:\Program Files (x86)").
b. Copy the entire program folder and its contents to the desired location on the new drive.
Update shortcuts and registry (optional): If you've copied the program files to the new drive, you may need to update any shortcuts or registry entries that point to the old installation directory. You can edit shortcuts to point to the new location and use tools like "Regedit" to modify registry entries if necessary. Exercise caution when modifying the registry, as incorrect changes can cause system issues.
Test the program: After moving the program, test it to ensure that it works correctly from the new drive. Open the program, perform any necessary configurations, and verify that it functions as expected.

If the primary voltage of a transformer is 230V and the primary coil is 80. Calculate the secondary voltage when the secondary turn is 160. *Ans 460 volts*
Answers
Answer:
\(V_{out} = 460\)
Explanation:
From your question, you already posted the answer
However, I'll give the steps to get the answer
Given
\(Primary\ Voltage = 230V\)
\(Primary\ Coil = 80\)
\(Secondary\ Coil = 160\)
Required
Secondary Voltage
The relationship between the primary voltage, secondary voltage, turns of primary coil and secondary coil is as follows;
\(\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}\)
Where
\(V_{in} = Primary\ Voltage = 230V\)
\(V_{out} = Secondary\ Voltage = ??\)
\(N_{p} = Primary\ Coil = 80\)
\(N_{s} = Secondary\ Coil = 160\)
Substitute these values in the formula above;
\(\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}\)
becomes
\(\frac{V_{out}}{230} = \frac{160}{80}\)
\(\frac{V_{out}}{230} = 2\)
Multiply both sides by 230
\(230 * \frac{V_{out}}{230} = 2 * 230\)
\(V_{out} = 2 * 230\)
\(V_{out} = 460\)
Hence, the secondary voltage is 460 Volts
Answer:
460 volts

Answers
The order of a finite field must be of the form pn where p is a prime and n is a positive integer.
A finite field is defined as a field with finitely many elements. The order of a finite field refers to the number of elements in the field. It can only be of the form pn where p is a prime and n is a positive integer. For example, a finite field of order 7 can be constructed with 7 elements. However, a finite field of order 8 cannot be constructed since 8 is not of the form pn. The theory of finite fields has applications in various fields such as cryptography, coding theory, and computer science. The operations of addition and multiplication are both commutative and associative. Hence, option D) Associative is not related to the order of a finite field.

Why error occurs during transmission? Explain different types of errors with suitable examples. 5 (b) How do you detect error using CRC? Generate the CRC code for the data word 1101011011 The divisor is x4+x+1. 7
Answers
During transmission, errors occur due to a variety of factors such as atmospheric conditions, system malfunction, or network errors.
Different types of errors include Single Bit Error, Burst Error, and Burst Error Correction. Here are the different types of errors with suitable examples: Single Bit Error: It occurs when one bit of data is changed from 1 to 0 or from 0 to 1 in data transfer. This type of error is mainly caused by a small amount of interference or noise in the transmission medium. For instance, a parity bit error.Burst Error: It occurs when two or more bits are incorrect during data transmission. A Burst Error occurs when bits of data are lost or changed in groups, which can affect multiple data bits at once. It can be caused by signal loss or attenuation in fiber-optic cables. Burst Error Correction: To overcome the issue of Burst Error, Burst Error Correction is used. This method divides data into blocks to detect and fix errors. Reed-Solomon coding and Viterbi decoding are two types of burst error correction techniques. There are different techniques for error detection, and the Cyclic Redundancy Check (CRC) is one of them. CRC checks the checksum at the receiver's end to ensure that the data was not corrupted during transmission. To detect errors using CRC, follow these steps: Divide the data word by the generator polynomial. Generator polynomial: x4 + x + 1 Divide 1101011011 by x4 + x + 1 and find the remainder by using the modulo 2 division method.1101011011 10011- 10011000- 10011000- 10010100- 10010100- 10000001- 10000001- 1111100- 1111100- 1001The remainder of the above step is the CRC code of the data word, which is 1001. Therefore, the CRC code for the data word 1101011011 is 1001.

Field data retrieval methods are referred to as Accessors, and field data modification methods are referred to as Mutators.
A mutators method is a technique used in computer science to manage changes to a variable. As setter techniques, they are likewise well-known. A getter, which returns the value of the private member variable, frequently follows a setter and together they are referred to as accessors.
According to the encapsulation concept, the mutator method is most frequently employed in object-oriented programming. In accordance with this principle, member variables of a class are made private to hide and protect them from other code. A public member function (the mutator method) is the only way to change a private member variable; it receives the desired new value as a parameter, validates it, and then modifies the private member variable. Assignment operator overloading and mutator methods are similar.
