Manipulated Data and How We are Affected

What I think was the main ethical issue with the discussion on Monday was how individuals and society can be influenced by the manipulated data. There was a consensus on the most important and urgent ethical issue, which was privacy regarding personal information. This is because some people use personal information for commercial or political purposes. Moreover, there was a discussion about Deepfake videos, which are fake videos that people cannot really distinguish from the real videos with naked eyes. This artificial intelligence and deep learning technique have been already used for making pornographic against celebrities and politicians.

Examples above are both about how manipulated data deeply impact how we see understand and absorb fake things on the world. Based on our personal information, companies make different advertisement tailored to each personality, and politicians give different types of messages. This can be dangerous because it can be a new phase that polarizes our society, divided by those who have big data and those who don’t have access to big data.

Deepfake videos are also huge problems as well. We all know the famous fake video of Obama giving a speech but he did not actually. Even though deepfake vidoes are yet used politically as much as they are for making pornographic, as the deep learning and artificial intelligence get better every time, it is a matter of time that we might see fake videos that instigate, reproduce and spread out hatred and disinformation.

Nevertheless, there is not a substantial solution to these problems since they are uncontrollable and inevitable unless every person quit using the internet. Thus, each individual, especially those people who manage websites and portals, need to be more responsible.

Determining Authenticity of Video Evidence in the Age of Artificial Intelligence and in the wake of Deepfake videos

Deepfake videos utilize artificial intelligence and machine learning algorithms to superimpose the faces of famous people, or even ordinary folks, onto the bodies of other people in different videos. Deepfake videos appear very realistic because machine learning allows the algorithm to continuously improve the image. This technology is often used in a sinister way to incriminate people in pornographic videos or to generate visual ‘evidence’ of events that never actually happened. The open-source artificial intelligence tool, TenserFlow, has been misused as a tool for creating Deepfake videos as the program relies on machine learning and image processing.

“Deepfake technology does its own google image search and scours through social media and can, by itself, replace faces in videos.  The program improves itself independently through machine learning.  Using this tech, anyone can create fake videos including pornographic videos of just about anyone.  Also, Deepfakes can be spread rapidly considering how quickly media is consumed and reproduced online. There is another technology that lies in this same vein, such as tech that can automatically alter images, and tech that can recreate voices.  The implications of this are that we may be looking at a future where people can create photos, videos, and audio of someone doing things they never did and saying things they never said.”

Development of crafty fake videos techniques influences jurisdictive decisions in courts as well. Videos and images have been strong evidence to prove eyewitnesses, but now it came to the situation that the validity of videos and images may be skeptical. Rather, videos might need to be proved by eyewitnesses. Another problem is that, yet, there are not many experts who know well about artificial intelligence and are capable of distinguishing fake videos from the real videos.

While it is only a matter of time before fake videos keep improving their performance, research in this field is sparse and so too are the necessary tools that could help stop the perpetuation of deep fake videos. Researchers have begun to make algorithms that can make these deep fake videos more easily identified but this same technology can also further advance the creation of these videos.

Overlooked weaknesses of the Internet and SNS

Social network services (SNS) such as Facebook and Twitter have a huge impact on society. SNS influenced politics, economics and our daily lives in every world. There are some countries in Europe that succeeded democratizing and SNS helped the processes. In Moldova, it cannot be denied that SNS helped to gather the crowd and fueled the flames of protests. More than 900,000 people gathered through a Twitter hashtag, but as soon as the government blocked the internet, they lost what to do and the will to fight. Two issues arose in my after reading the article.

First, should the government censure any stuff in SNS? I think there need to be some regulations to prevent sexual abuse, violence and any inhumane discriminations. However, the problem is that once the public gives the government a power to control the internet and SNS, they can do something other than what they were supposed to do in specific occasions like political protests.

Secondly, I realized that people have been overlooked the blind spot of the internet and SNS. What happens if we don’t have access to them and if this is intentional by some parties? This sounds unlikely, but it is a point to think about. People hugely rely on computers, internets and SNS, and they are definitely helpful. But at the same time, we need to know that they also have some limits. They are not something operated automatically, but instead, they are controlled and managed by someone with intentions. In the article we read, Moldovans did not know how to keep protests when the internet was blocked.

Data search: linear and binary search

During the last week, our class discussed more foundational and abstract algorithms in the perspective of the computer. First, we talked about two different means of searching, linear search, and binary search. They were different in the way of searching the target data and this led to higher or lower efficiency in certain situations. The linear search conducted a sequential search starting from the first data of the range. This mean of searching was very straightforward and take more time than other methods but it was advantageous when the data were not sorted. In contrast, the binary search had a specific algorithm which allowed shorter trials until reaching to the target data. The only shortcoming of it was that it cannot be conducted if the user doesn’t know how the data is sorted.

I could better understand the application of these methods after the Huffman encoding tree. It was interesting to see during the lab that the most frequent letter appears near the top of the tree where the depth is not large. This allowed the data to be compressed as much as possible.

Overall, these discussions and materials were about a very small segment of data search, which includes farther accuracy, memory, and re-usability, other than just efficiency. This approach was coherent to what one of the readings said in the class. In order to develop a human familiar software and applications, understanding the foundational algorithm of how the computer inherently works should be prioritized.

Coding Education is Necessary, but How?

The importance of coding education has been mentioned in the last decades. I heard that learning at least one computer language is helpful no matter what major I am in college. I also read an article that the future industry will be divided into those who have A.I., and those who don’t have A.I.

Two articles about coding education in public schools well reflected these social atmospheres. Coding education led by major companies like Facebook and Google is fostered in primary and secondary education. Parents already know that learning computer programming is the key to the future, and their children should learn it to prevent from falling behind.

I believe these trends are meaningful in that coding education allows computer and programming to be the shared legacy of all people. However, as discussed in the class, the distinction between coding and programming is definite and educators are necessary to more focus on programming. Coding is more close to mechanical technique, and programming is an understanding of how coding computer language works. Richtel wrote in the New York Times that “it is not clear that teaching basic computer science in grade school will (…) foster broader creativity and logical thinking.” To promote more constructive coding education, students need to be exposed to the fundamental mechanism of coding lied upon software and applications. This is similar to the emphasis on critical thinking and debating than just mechanically solving many numbers of problems in mathematics.

Coding Education

<Reading, Writing, Arithmetic, and Lately, Coding>

Coding education became nationally prevalent in public schools and the grade to learn coding gets lower as times goes. Most of the parents wanted their children to be prepared for the future, and do not fall back. Some schools were teaching coding as after-school programs, some other schools were taking coding as regulatory courses and it was a major requirement for graduation. While some experts expected a positive effect of being exposed to computer science from early ages, some educators concerned that few big companies were taking too much role in coding education.
In the course of action over the years that computers have evolved in use and influence, so has their role for within society. In the time, as with its main method of use, coding. In the time of computers becoming a part of everyday lives, children are more often than not influence to learn more about them through the education system, so as to follow through with early development. However, with all other things, there is a debate on just how much influence should activities that involve a computer should be within their growing lives, without being unhealthy. Opinions vary on such, but in the end, the influence computers will have on people’s lives will not stop.

 

The second reading we did was the transcript of a speech given by President Obama in a weekly address. He framed coding as a skill that was necessary for the future, one that should be taught in every school. He announced pushes by his administration to fund computer science programs in elementary and high schools. The funding would go towards resources for the actual classes along with teacher training. He promoted state and local initiatives that would accompany federal promotion of computer science. President Obama presented coding as a fundamental skill for a changing economy.
Obama’s Computer Science for All initiative acknowledges that learning how to write code is necessary for the digital economy, and seeks to make it accessible to students of all ages. It builds a national coalition in an attempt to rectify disparities. By using Queens and New Orleans as examples, Obama’s choice of words indicates a desire to make these skills attainable for minority communities which have been traditionally left behind, shooting for an equal playing field.

Wampum as Hypertext: An American Indian Intellectual Tradition of Multimedia Theory and Practice

The reading of Wampum as Hypertext describes the origins of the ideas behind Hypertext, which actually began with the ideas from the Native American’s wampum belt, in which textile showed specific patterns and links are used in order to represent and read as memory and information. While initially appearing complicated, a person who understands the pattern work would have access to such information through the lines of the wampum and would know the finer details. This idea proved to be a rather profound idea that would arrive to use in the modern era with the creation of hypertext, also in which a person would have access to numerous amounts of related information, created through the patterns of code and programming, similar to wampum textile. These ideas proved to be revolutionary to the internet, and the access of it allowed for easy access to information and quicker development of the computing system

Both wampum and Western hypertexts show digital and visual rhetoric. Wampum communicates through combinations of dark purple and the white beads, just like computers use zero and one. They also share nonlinear networks which contain layered information and narratives, sharing more than one story within each of their respective sections. As well, both act as supplemental memory. Hypertext contains troves of data readily available for research, while each bead within a wampum belt is a node representing information. Moreover, the very nature of wampum is interactive; nodes create association between symbolic representation and the spoken word, with connecting material linking to related information, and the belt as a whole represents the relationship between the “giver” and “presenter” of the belt. All of this lends itself to the power of wampum as a hypertext of community knowledge. Thus, unlike to Western hypertext, people should belong to the community in order to interpret, present, and recreate wampum communications.

Understanding the connections between wampum and hypertext credits American Indians as understanding and developing technologies in their own right. It also poses the question, “whose definition of technologically advanced are you using when evaluating your technological proficiency?” (Haas 94). Haas argues that the west does not get to decide unilaterally what constitutes advanced technology.  She does not believe that western hypertext in its digitized format was originally conceived of by American Indians. Instead, she highlights the fact that American Indians, too, developed a concept of an interconnected web of information, and that their version of this web is a different version of technology yet equally valid.

Depression Quest

I think everyone including myself had some moments in their life when they felt depressed without many reasons and act pessimistic. On this Depression Quest, I kept choosing the options that I have done when I felt depressed before. It could have been boring since it was a pretty long story, and the repertoire was repeating a lot. But at the same time, I was pulled into it, because it was me who was actually making choices, not just reading what the character was doing. I had more opportunities to think more about the situation and how would the character feels like. This was similar to an interactive film Black Mirror: Bandersnatch that came out in 2018.

Moreover, some words were highlighted in the passages and I could find more details about them before I read any further. For example, when Alex was first introduced, I clicked it and I could see what personality characteristics she has, what kind of job she is working on, and how she met the main character. This format of reading allowed me to concentrate on the things that I want to know about and did not interrupt the flow of reading by not giving redundant information in the main passages.

As the story continued, it was interesting that some of the choices that I could make were blocked. Maybe it is because the decisions I made earlier affected the later choices. However, sometimes I wanted to choose the choice that was blocked, but I couldn’t, so I had to choose the alternative among the rest of the possible choices. Particularly in the story that deals about human emotion, it varies a lot as time goes, depending on the different situation, so it might have been better if I was allowed for all the options.
