Week 2 Discussion – Tinker Case

After completing this week’s readings, access the link below and read “Tinker v. Des Moines Independent School District.”

As you look at the Tinker case, you will note that one of the dissenting judges (Hugo Black) argued that the “time had come when pupils of state-supported schools…can defy and flout orders of school officials”

  • In your opinion, is this case more about Freedom of Expression, or were students allowed to defy the principal’s rule? Give the reason behind your opinion.

Your initial responses are due by 11:55 p.m. Eastern Time on Wednesday and should be between 200-250 words. The initial posting should be a statement of your point of view on the question, supported by the required readings.

Lesson 1 Discussion Forum: Read Instructions

Team Leadership/Management Style

Part 1: According to the Sarin and O’Connor (2009) article, certain style and goal structures of team leaders have a strong influence on internal team dynamics.  Based on your research within the article and textbook, as well as your own experience, what team leader management style would be most effective in leading a team in which you were a member?

Part 2: DeRue, Barnes, and Morgeson (2010) found that team leadership style effectiveness depended on the level of charisma exhibited by the leader.  Drawing from the article and the textbook, have you ever worked for a charismatic leader?  What style (coaching or directing) did that leader administer?  Was he or she effective in leading you as part of the team?

Instructions

Use research from at least 3 academically reviewed journal articles to support your responses. Do not use internet and other non-academic articles for these discussion questions.

Abstract:   

Simulating market values and market indices has become challenging task for variable annuity (VA) in related to computational costs, usually VA using Monte Carlo method to calculate sensitivity of the fair market values. Although such simulation deals with huge computational costs. In this paper we discuss about the machine learning models and data science concepts to address the road map for the problem (difficulty in finding market values and market indices of future time points) being arised in VA.

Introduction to Field of Research:

Machine learning:

Machine learning is a utilization of Artificial Intelligence (AI) that gives systems the capacity to naturally study and enhance as a matter of fact without being expressly customized. Machine learning centres around the advancement of PC programs that can get to information and utilize it learn for themselves.

The way towards learning starts with perceptions or information, for example, cases, coordinate involvement, or guideline, keeping in mind the end goal to search for designs in information and settle on better choices later on in light of the cases that we give.

Data Science:

Data Science is the comprehensive assistance under which all additional types of analysis pertinent. Data cleansing, manipulation, and selection of the type of analysis that involved to be finished are important pieces of the data science foundation. Without these foundational items being achieved, your data analysis will no way truly be precise.

Information researchers need to see how the hidden information is made, the business targets and objectives, the uses of the information and the expectations, and how to translate the information through information narrating and connecting with representations.

Key Related work:

6-machine learning models

  1. decision tree based method :

The major learning approach is to recursively partition the preparation information into pails of homogeneous individuals through the most discriminative isolating criteria.

The best part of Tree method is that, it is extremely adaptable regarding the information sort of info and yield factors which can be clear cut, paired and numeric esteem. The level of choice hubs likewise demonstrate the level of impacts of various info factors. The impediment is every choice limit at each split point is a solid twofold choice. Like-wise the choice criteria just think of one as information traits at once yet not a blend of different info factors.

 

 

 

  1. Linear regression method

The fundamental suspicion is that the yield variable (a numeric esteem) can be communicated as a direct mix (weighted whole) of an arrangement of information variable (which is additionally numeric esteem).

y = w1x1 + w2x2 + w3x3 ….

The entire target of the preparation stage is to take in the weights w1, w2 … by limiting the mistake work lost(y, w1x1 + w2x2 + …). Inclination plunge is the established strategy of taking care of this issue with the general thought of altering w1, w2 … along the course of the greatest slope of the depletion function.

  1. Neural Network:

Neural Network can be considered as different layer of perceptron (each is a calculated relapse unit with numerous paired info and one parallel yield). By having numerous layers, this is identical to : z = logit(v1.y1 + v2y2 + …), while y1 = logit(w11x1 + w12x2 + …) .

This multi-layer demonstrate empowers Neural Network to learn non-direct connection between input x and yield z. The commonplace learning system is “in reverse mistake proliferation” where the blunder is spread from the yield layer back to the information layer to change the weight.

  1. Bayesian Method:

It is essentially a reliance diagram where every hub speaks to a double factor and each edge (directional) speaks to the reliance relationship. In the event that NodeA and NodeB has an edge to NodeC. This implies the most likely of C is genuine relies upon various blends of the boolean estimation of An and B. NodeC can point to NodeD and now NodeD relies upon NodeA and NodeB too.

  1. Nearest Neighbour method:

Nearest Neighbour require the meaning of a separation work which is utilized to discover the closest neighbour. For numeric information, the basic practice is to standardize them by less the mean and partitioned by the standard deviation. Euclidean separation is normally utilized when the information is autonomous, generally mahalanobis remove (which represent relationship between sets of information highlights) ought to be utilized. For paired properties, Jaccard separation can be utilized.

  1. Support vector machine method:

Support Vector Machine takes numeric info and double yield. It depends on finding a direct plane with most extreme edge to isolate two class of yield. Clear cut info can be transformed into numeric contribution as previously and straight out yield can be displayed as various paired yield.

Key aims of your project

In this project machine learning models are applied to predict simulated values and able to acquire highly in-demand skills in machine learning and data science, and apply such skills to solve a very important problem to the insurance industry. By the end of the project we will be likely to project technical skills and achievements to employers in order to do research publication.

The research problem and key research questions you intend to investigation

In this venture, you will apply machine learning models to foresee the reenacted esteems. You will have the capacity to gain exceptionally sought after aptitudes in machine learning and data science, and apply such abilities to take care of a vital issue to the insurance industry.

Research Questions

1) How to simulate market values, market indices and market future times using machine learning and data science?

2) How could technical concepts from machine learning can reduce computational costs for variable annuity?

The research methodology you intend to employ

Quantitative:

Polls regularly appear a legitimate and simple choice as a method for gathering data from individuals. They are quite hard to outline and on account of the recurrence of their implementation in all settings in the advanced world, the reaction rate is almost continually going to be an issue (low) except if you have methods for influencing individuals to finish them and hand them on the spot (and this obviously restricts your example, to what extent the survey can be and the sorts of inquiries inquired). Their design is a work of art in itself in light of the fact that in ineffectively spread out poll’s respondents tend, for instance, to rehash their ticking of boxes in a similar example. In the event that given a decision of reaction on a scale 1-5, they will for the most part settle on the centre point, and regularly tend to pass up a major opportunity subsection to questions.
