Windowing technique uses the concept of sliding window. This is well liked tactic to hand out with time emerging data. Sliding Window give permission to limiting the samples which is going to learn as well as it flush out the old data and add new data, so the paradigm gain the newest idea. The basic idea behind this windowing algorithm is very clear. In windowing technique each sample update the window rather than updating by classifier. A double window strategy shows in “Ref. ”.
j. Weighted Windows
Weighted window uses decay function. This decay function will helpful for flushing out previous samples which are of no need. Decay function allocates some weight to samples in window. In weighted window previous samples gains little weights and it has less privilege than new sample, that’s why they are less important than classifier. Cohen and Strauss provide use of decay functions for data stream aggregates calculation, given in “Ref. ”.
Zliobaite proposed a technique called FISH algorithm. FISH make a use of time and space uses time and space likenesses between samples for creating window dynamically. The standard hypothesis is given in “Ref. ”. In which the selection of samples is based on distance measure. To properly manage the balance in between time and distance, the distance and time should be normalized. The next part of FISH is FISH2, FISH3. Time/space proportion is takes as parameter in FISH2 algorithm. While in FISH3 for each incoming new instance FISH3 algorithm computes time/space proportion and size of window differently.
So the Family of FISH algorithm is very useful while classification when the dynamic windowing technique is necessary in drift detection.

For solving drift detection problem it required learning algorithm and hoeffding bounds algorithm. When change occurs in data samples drift detection method works. During the classification process the accuracy of the algorithm is improved. Since drift detection and classification algorithm adapted while change occurs in data stream.
This Paper describe about concept drift and its types, it’s requirement and details of changes. There are various techniques DDM, EDDM, DDD, Drift detection through resampling, HDDM, DCDD along with that some windowing techniques, ensemble methods, and statistical method are made known in this paper. DDM is very suitable for sudden concept drift but it lack in detecting the slow change in data stream so the next technique EDDM will help to overcome this drawback. In determining the error generation diversity plays an important role.

- The Johari window is a great communication concept to build trust with others and improve understanding between people. According to (Satterlee, 2013, p. 134), “communication is a process that is vital to transmitting and understanding information”. However, communication is set forth as goal-oriented; the end result for the communicator is to achieve that set goal in order for the message to be considered effective. According to (Darling & Beebe, 2007, p. 76), “communication is the primary way in which any group of individuals, small or large, can become aligned behind the over-arching innovative goals of a creative developing organization”....

- Rear Window is an entertaining movie using voyeurism as a story element. For me it has a double meaning; first like the rear view mirror in a car one is always looking in it to see out of the rear window, at who or what is behind us, looking over our shoulder. The concept of ‘Looking over your shoulder’, brings to mind a paranoia of being followed or watched. The second is meaning of the movie’s title is more apparent in that the rear windows of the visible apartments share a common view of a circular enclave or backyard view of other neighbors who share the same visual experience....

- Through subtle and discrete methods, Saki implies vast amounts of truth about society. How at ease and dependant one can become – that one neglects to see the immature and fraudulent intentions underneath – throughout his short story “The Open Window”. Saki’s story which has a character whose art of deception, which takes in the form of maiming the real meaning of the open window and disguising it in her lies, to the point where her victim’s gullibility takes a toll open his well being is a clear and distinct representation of one’s malevolent intents....

- Patient participation has been poorly defined especially in nursing practice due to lack of freedom from indistinctness or ambiguity in health care (Sahlsten, Larsson, Sjostrom, & Plos, 2008). The concept of patient participation plays an important role in health care nationally and globally. The meaning of patient participation varies greatly based on individual patient and nurse’s perception. This concept analysis it to gain clarity through Walker and Avant concept analysis method by identifying and presenting the purpose, attributes, model case, antecedents, consequences and empirical referents of the concepts....

- As the credits roll we see the blinds of a three-pane window slowly being lifted up, after they finish the camera moves forward revealing to our gaze the reality on the other side of the open window. It faces the back of many other buildings, the courtyard they enclose, and a sliver view of the backstreet. More importantly, it faces many other windows just like it. Behind each one of those there are people, going about their day, doing mundane tasks, unaware of being observed. In his 1954 movie “Rear Window” Alfred Hitchcock invites us to engage in the guilt free observation of the lives of others.... [tags: Rear Window, Alfred Hitchcock, Film Analysis]

- An Analysis of Frost's Tree at my Window "Tree at my Window" was written by Robert Frost, an American poet who was born in 1874 and died in 1963 (DiYanni 624). His poem will be the basis of the discussion of this brief essay. The narrator in this poem appears to be speaking to the "tree at my window"; then, repeating the phrase in reverse order, he calls it the "window tree," as if to emphasize the location and nearness of the tree. Calling the tree a "window tree," might also suggest that this tree is something he sees through, perhaps to some higher truth, to something beyond the mere physical presence of the tree....

- Alfred Hitchcock’s Rear Window In Alfred Hitchcock’s Rear Window, L.B. Jeffries, played by Jimmy Stewart, becomes completely obsessed with spending all of his waking hours watching his neighbors from his wheelchair. He even uses a camera to better his view and thus enhances his role as both a spectator and a voyeur. This contributes to the creation of a movie being played right outside Jeffries’ window. In this “movie within the movie” his neighbors’ lives become the subject for the plot. Each window represents a different film screen, each which is focused upon only when Jeffries directs his attention to it.... [tags: Movie Film Rear Window Essays]

- Imagery in Robert Frost's Wind and Window Flower After reading this poem by Robert Frost, I was left with many different ideas about this work. I believe one could take this poem in a literal sense to actually be about a window flower and the wind. I also believe, however, that this poem perhaps has a bit of a deeper meaning. Looking first at the poem in a literal sense, the story is told of a lonely window flower that is sitting on a window sill, and the image is that the flower is looking out the window....

- The Self-Concept is a complicated process of gaining self-awareness. It consists of mental images an individual has of oneself: physical appearance, health, accomplishments, skills, social talents, roles, intellectual traits, and emotional states and more –all make up our self-concept. The development process begins at about six or seven months of age. The child begins to recognize “self” as distinct from surroundings. They stare at anything they see, including their own body parts; hands, feet, toes, and fingers.... [tags: Self Concept]
