Weka programme - Essay Example It is a free software issues under GNU General Public License. Weka stands for Waikato Environment for Knowledge Analysis. It is the software which allows businesses to extract useful information out of large databases. This is the process of data mining which is a field that analyzes large sets of data and discovers patterns and methods for the management, processing, and inference considerations of the data. Weka software offers businesses a collection of learning tools and schemes that may be used for data mining (Witten, 2011, p. 132). There are four applications in the program which are accessible; these are Explorer, Experimenter, KnowledgeFlow, and Simple CLI. The first section of the software is to open the database or the dataset and make the edits as the user wishes. These edits include the filtering of data contents, changing of attributes, and visualizing the result in a bar chart. The available data can also be classified according to the set of rules which are predefined and can perform a complete analysis of cost-benefit that would display automatically the threshold curve and the cost matrix (Witten, 2011, p. 132). Moreover, the program also has many tools for the data clustering, attributes evaluator, and association rules. In addition, businesses also use it for the data plotting allowing the user to view and analyze the point graphs individually for each possible attribute combination. Businesses also use the weka programme as it is suitable for the development of new machine learning schemes. The user simply has to configure the experiment by choosing the type: classification or regression. Then the desired data set and algorithm has to be chosen and then it is ready to be run. The results of this procedure can be saved in CSV format or ARFF or as JDBC database. A data file can also be analyzed or tested through the program as it allows the user to choose the comparison field and the sorting criteria on

Kindergarten Cop and Daddy Daycare movies analysis Essay

Kindergarten Cop and Daddy Daycare movies analysis - Essay Example Two films that depict such deviation from traditional gender roles are â€Å"Kindergarten Cop† and â€Å"Daddy Daycare†. Kindergarten Cop stars Arnold Schwarzenegger as a police officer tasked with a mission to catch a dangerous criminal. Posing as a kindergarten teacher, John Kimble, he initially struggles with his newfound role as a carer and educator of very young children. Daddy Daycare, on the other hand, stars Eddie Murphy as a former executive, Charlie Hinton, who was laid off from his job together with his best friend, Phil. Left in the house, unemployed, with their wives going to work, they take care of their children until the idea of putting up a daycare sprung to their minds. The local preschool, Chapman Academy, is a plush school that offers a sophisticated curriculum for the young ones at a very steep price. The people around the neighbourhood did not have any other choice for a quality preschool/daycare for their children, so Hinton (Eddie Murphy) and his friend, Paul set up one at his home. At first, people expressed surprise and suspicion about men taking over the jobs of teachers of young children, which were traditionally associated with women due to their nurturing nature. The movies showed how they initially fit in so well in their original jobs as a police officer and a corporate executive and were awkward in their new jobs as child minders. The social repercussions showed a â€Å"demotion† in status, and this was clearly manifested by a colleague of Hinton when he scoffed at him being a daycare teacher, coming from a privileged position in the company, and then labelled him a â€Å"loser†. Part of adjusting to their new role is the use of skills they used in their old jobs. For John Kimble (Schwarzenneger), it was the use of police tactics and military training to instill discipline in the children while for Charlie Hinton (Murphy), it was the use of presentation skills, including furnishing the pre-schoolers w ith a copy of the mission and vision of Daddy Daycare, which of course, failed miserably. Kimble was more successful because of the element of fear that came with his disciplinary measures. The children were too scared of the â€Å"giant† teacher not to obey. Later on, he modified his strategy to playing a game appointing the children as â€Å"trainees† in a police school. On the other hand, Hinton used a more child-centered approach, which is engaging in fun activities and consulting the children of what they would like to do and learn at Daddy Daycare. As the movies progressed, so did the characters’ competencies in handling young children. Their softer sides surfaced, showing tender scenes with the children. Although their machismo remained, the movies portrayed that it is alright for real men to be nurturing to children, and if that takes doing women’s roles, then it is acceptable too. Lynn Trodd, head of the Children’s Workforce Development Co uncil contends that research shows that men perceive working in an early years environment is not as prestigious as corporate jobs, have fewer career opportunities, has a vague career structure, the pension system is not in place and there is less in-service training. To top it all, it does not pay well. Being so, it is seen as a far less professional area of work (Men in Primary- Early Years). However, men can be a great resource to the children’s workforce as they bring with them their own special skills and
