Abstract- Outlier detection is an active area for research in data set mining community. Finding outliers from a collection of patterns is a very well-known problem in data mining. Outlier Detection as a branch of data mining has many applications in data stream analysis and requires more attention. An outlier is a pattern which is dissimilar with respect to the rest of the patterns in the data set. Detecting outliers and analyzing large data sets can lead to discovery of unexpected knowledge in area such as fraud detection, telecommunication, web logs, and web document, etc. This paper focuses to clarify the problem with detecting outlier over data stream and specific techniques used for detecting outlier over streaming data in data mining. …show more content…
INTRODUCTION Data mining extracts hidden and useful information from the data. Valid, previously unknown, useful and high quality knowledge is discovered by data mining. Outlier detection is an important task in data mining. Outlier detection has many important applications and deserves more attention from data mining community. Outlier detection is an important branch in data pre-processing and data mining, as this stage is required in elaboration and mining of data coming from many application fields such as industrial processes, transportation, ecology, public safety, climatology. Outliers are data which can be considered anomalous due to several causes. Outlier detection techniques are used, for instance, to minimize the influence of outliers in the final model to develop, or as a preliminary pre-processing stage before the information conveyed by a signal is elaborated. On the other hand in …show more content…
Statistical Outlier Detection Statistical outlier detection uses certain kind of statistical distribution and computes the parameters by assuming all data points have been generated by statistical distribution. In this approach outliers are points that have a low probability to be generated by the overall distribution Statistical outlier detection technique is also known as parametric approach. This technique is formulated by using the distribution of data point available for processing. Detection model is formulated to fit the data with reference to distribution of data. A Gaussian mixture model was proposed by Yamanishi et. al.[1]. Where each data point is given a formulated score and data point which have a high score declared as outlier. Detecting outlier based on the general pattern within data points was proposed by [2] where it combines a Gaussian mixture model and supervised method Depth based outlier detection [3] is one of the variant of statistical outlier detection. Depth based outlier detection search outliers at the border of the data space bur independent of statistical distributions. These techniques are generally suited quantitative real-valued data sets or quantitative ordinal data distributions. In this approach each data object of dataset represented by an n-D space having a assigned depth. These data points are organized into convex hull layers according to assigned depth and outlier is formulated on the basis of shallow depth values. Outliers are
Malcom Gladwell, the author of The Outliers, analyzes the factors to success based on real-life example. Through statistical facts and logical reasoning, he attempts to prove how success is more than just hard work and being intelligent. He supports his arguments with accurately calculated statistical facts to gain the trust of his audience and to work towards 2proving his points. Gladwell determines the reasons of success by comparing well-known successful people and finding commonalities between those people. Gladwell does not believe anyone can be a self-made man.
What is meant by ‘statistical infrequency’ as a definition of abnormality? [2 marks] Gavin describes his daily life. ‘I sometimes get gripped with the thought that my family is in danger. In particular, I worry about them being trapped in a house fire. I now find that I can only calm myself if I check that every plug socket is switched off so an electrical fire couldn’t start.
I read the book's Outlier, it is really interesting because there had a lot of numbers as the table format. The psychologist from Canadian was Roger Barnsley made relative age, he was looking at birth and height. For example, hockey team had relative age like date of their birth. I seem there had a lot of common like how the player had good strength and all players are taller about 5’8 to 6’5 height. And also, Roger Barnsley believe players who boring on January and March are best players.
The definition of an outlier is someone who stands apart from others of his or her group, as by differing behavior, beliefs, or religious practices. Gladwell’s novel revolves around the idea that being an outlier can be beneficial to one’s potential prosperity. Gladwell’s theory checked out when a Canadian psychologist named Roger Barnsley discovered relative age when he and his wife attended a Medicine Hat Tigers hockey game. While looking at the roster, they realized that a majority of the player’s birthdays were in January, February, and March. They then researched other hockey teams and found the same pattern, even for teams with young children.

Outliers “The Story of Success” has opened my mind to certain things that were still unclear in my head. Like how just acting different in a similar situation can prevent a tragedy or stuff from happening. What we as human beings are capable of doing with so little effort and what we can do with so much more. The book inspired me.

The legacies people inherit from their families act as personal psychics that influence their futures and explain the reasoning behind the choices they make. Malcolm Gladwell, author of nonfiction book Outliers: The Story of Success supports this concept of how legacies influence people and the choices they make. He coins this concept as “cultural legacies” and defines it as: “powerful forces that play such a role in directing attitudes and behavior that we cannot make sense of our world without them,” (175). Gladwell explains the cruciality of the cultural legacies in people’s success, decisions, and how these legacies influence how people function.

According to Gladwell, successful women and men alike gain specialization, partnership, time, locations, and culture (Locklear, 2016). An outlier’s method for success is not personal beliefs but the synthesis of opportunity and time on task (Locklear, 2016). The book “Outliers: The Story of Success,”
Argumentative Essay What if the phrase “practice makes perfect” wasn’t actually true? Malcolm Gladwell claims that it takes 10,000 hours of practice to perfect a skill, however, some people are starting to believe that may not be the case. “Your Genes Don’t Fit. Why 10,000 Hours of Practice, Won’t Make You an Expert”, argues that mastering a skill requires innate abilities along with practice.
Outliers by Malcolm Gladwell teaches you the understanding of success. Malcolm Gladwell in the book Outliers uses logos, pathos, and ethos to get his argument across. Outliers was written for the purpose to show the audience that success isn’t all on how hard you work, raw talent, intelligence or personality traits. Success comes from your culture, who your parents are, when you were born and the opportunities you have been given. The argument by logic, emotion and character are all put into Outliers to convince the readers that success is what you make of it.
Gladwell’s Formula for Success Malcolm Gladwell’s book, Outliers: The Story of Success delves into the different aspects and situations that allow for individuals to become immensely successful. In doing so, he has come up with an enticing formula that suggests that success is the result of fortunate circumstances more so than just hard work and innate talent. He attempts to make the reader view success differently than is traditionally accepted. His formulaic approach has resulted in much support as well as severe criticisms such as Michiko Kakutani’s remark that he “tries to extrapolate [his] observations into broader hypotheses about success…

Intrinsic factors critically considered when people think about the main components of success. However, Malcolm Gladwell, a famous writer, contradicts this tendency through the book, Outliers. The book, Outliers insists that extrinsic factors define success rather than the intrinsic ones. Nonetheless, Gladwell himself goes against the topic of Outliers in his assertion: “if you work hard enough and assert yourself, and use your mind and imagination, you can shape the world to your desires (Gladwell, 2008).” The assertion implies that individuals could achieve success only with those intrinsic factors.
