Data mining is a system that brings up the light to hidden and valuable information from the data and the facts revealed by data mining which were previously not known, theoretically useful, and of high quality. Data mining offers a means by which we can explores the knowledge in database. Data stream mining and finding outliers are dynamic research areas of data mining. Outlier detection is a division of data mining and has many applications in data stream analysis. This requires consideration from researchers. It is thought that ‘data stream mining and outlier detection’ research has drastically expanded the range of data analysis and will have profound impact on data mining methodologies and applications in the long run. However, there are …show more content…
a normal or Poisson distribution. In case of data streams unconventional knowledge about the data distribution may not be known. Cluster based approaches, such as DBSCAN, CLARANS [14], etc. have been used for outlier detection in different variety of datasets. During identification of clusters, outlier finding is treated as a byproduct. The problem with this approach is that it is mixing of two problems instead of solving each problem individually. Density-Based Approaches adopt a Local Outlier Factor (LOF) for outlier detection [15]. Outlier detection (exception mining, deviation detection, novelty detection, etc.) is a critical issue that has attracted wide interest and different solutions by researchers. There are many outlier detection methods in the literature and in practical use. If data for analysis is given with domain expert-provided labels that can be used to build outlier detection model. This method can be divided into: Supervised, Semi-supervised, and Unsupervised methods, whereas based on assumption, categorization of outlier detection methods are: Statistical methods, Proximity-based methods, and clustering-based methods …show more content…
Disadvantage Model-based approach needs the building of a model, which is often an expensive and difficult task requiring the expertise of a domain expert.
4.2 Connectedness [17]
In application domains where objects are linked (social networks, biological networks), objects with lesser links are considered potential anomalies.
Disadvantage
Connectedness approaches are only defined for datasets with linkage information
4.3 Density-Based [18] Objects in low-density regions of space are marked and treated as
Detection phase After obtaining the parameters, HsMM could be used to check whether the given observation sequences of SNMP-MIB variables correspond to normal profile or bot profile by calculating their average log likelihoods. The forward-backward algorithm is used to calculate a sequence’s likelihood against a given model. ALL values of training sequences for the normal and botnet systems are computed. If the observation sequence’s ALL value lies in a particular confidence interval, then it will be considered as normal profile. Similarly confidence interval for botnets is identified.

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.
When thinking about success, people automatically think about how hard people have worked to be successful. In the book Outliers, Malcolm Gladwell argues that we should look at the world that surrounds successful people such as, their culture, family, experiences, and their upbringing. Gladwell has made an interesting argument about how people become successful. Gladwell wants to convince readers that different kinds of explanations of success do not work.
Malcolm Gladwell states in Outliers that 10,000 hours of practice in a sport or hobby or career, will propel one person over another. He tries to convince us with his argument by bringing up people like Bill Gates and the Beatles, stating that they spent more than 10,000 hours perfecting their craft. At first his argument seems pretty legit and holds merit, but then you begin to question. What if someone practices for 10,000 hours, but doesn 't put in much work? What if someone, who has spent few hours than 10,000 is excelling?
In Outliers by Malcolm Gladwell, he proves there are numerous factors that which influences the success of failure. To support his idea, he uses examples to demonstrate there are no outliers when it comes to personal success stories. First example is the cut-off date of the Canadian Hockey League, how Bill Gates and the Beatles spent at least 10,000 hours practicing or working on their expertise. In addition, he uses the stories of Chris Langan, and Robert Oppenheimer to compare how one can succeed and how we can fail whether we have extremely high IQs or not. Furthermore, Gladwell utilizes the story of Joseph Flom to show how he was able to build a successful law firms because he wasn’t able to get hired because of racial discrimination.
Not everyone is fortunate enough to be granted with opportunities-- a chance at success. Even then, not everyone is able to utilize them to the fullest -- if the person even takes advantage of it at all. Granted, if the opportunity was even realized in the first place. Malcolm Gladwell, author of Outliers, essentially defines an outlier as a person that takes advantage of a set of opportunities presented to them. These sets of opportunities are not available to everyone and Wes Moore, the author of The Other Wes Moore, happens to be one of the few were fortunate enough to have a set of opportunities prepare him for success.
My younger brother (Ken) and his son (Ty) are two examples of “Outliers” in my family. Although the product of a broken home, with a father both alcoholic and abusive, Ken married his high school sweetheart (Cheri) shortly after graduation. Their marriage though not perfect, soon was blessed with a son making for a happy family and strengthening Ken’s resolve to do better than he had been taught. Life
As Gladwell explains what an outlier is, he explains an outlier to be a person who is out of the ordinary. 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.
