Bayes' theorem

Introduction To what extent is Bayes theorem used in the crowdsourcing of Pandora? Crowdsourcing is the gathering of information on the internet through tags, likes, and what sites a user visits. Crowdsourcing is an asset to advertisers seeking to find a target audience to sell a product. Bayes theorem describes the probability of an event based on prior knowledge that might be related to the event. Pandora music is a service that creates a radio station related to an album, genre, or artist of the user’s choosing. Crowdsourcing is used in Pandora to allow the user to personalize their own radio station. I have a personal interest in how the internet functions and how what seems a simple task like liking a picture can change how the internet…

This September, I started my MSc at UBC SPPH with a goal of becoming a researcher on clinical trials. During the past semester, I discovered I love it more than I could imagine. I enjoy everything that I am doing, especially my research which I can work until 3 am in the morning without feeling tired or exhausted. I count myself as a fortunate person as I have found what I love, unlike many other people who spend their entire life looking for what they like. However, as a person who wants to…

The second source is a book which introduced the basic concepts and applications of this methodology. The authors concentrated on the causal discovery of networks and the techniques of using Bayesian networks. Furthermore, they discussed the utilisation of this methodology for causal modelling. This source is important at the initial stage of the project as it contributes to the decision-making process at the modelling technique selection stage. However, it is not as important as the other two…

This uncertainty includes the quantities resulting from lack of sufficient information. Another important concept in Bayesian methods are the need to determine the prior probability distribution (probability distribution describing our beliefs about the uncertainty in the model before data becomes available) taking into account the available information. Generally, Bayesian methods involve the sequential application of the Bayes formula and the steps in these methods can be summarized as…

Mathematical proof is a method used in both primary and secondary schools at varying levels. Children should be able to justify and give reasons for a conjecture they have produced in order to validate a mathematical proof. There are various techniques that can be used to illustrate the nature of proof in schools. Mathematical proof is defined as a thorough and believable argument to support the truth of a prediction in maths, which turns the assumptions into valid conclusions (Haylock and…

standard practices during the time period because he prefers pleasure from sex from unconventional methods over loyal monogamy. Septimus is academically tutoring Thomasina, but is also teaching her sex in a unique manner considering their time period. This introduces Thomasina’s desire for knowledge, but also how sex and mathematics can be a societal battle. Septimus then immediate contrasts sex to math in order to portray how even though they seem like binary oppositions, they are immensely…

As we delve deeper into our theories on interpersonal communication, we begin to learn more about ourselves and how to interact with the people around us. Whether they are in our lives on a personal, professional or combined capacity. This week I have decided to look at the theories of Interactional View and Genderlect Styles (Griffin, 2015). When we study Interactional View, a theory developed by Paul Watzlawick, we can see how communication has shaped us into the people we are today.…

that one of the central goals of school mathematics, notably at the upper secondary level, is the development of proof concepts (Coe & Ruthven, 1994). The incorporation of algebraic proofs in Victorian Mathematics education also refutes the criticism that the focus on algebraic proofs theme is sporadic at the secondary school level (Pedemonte, 2008). Many different methods of proof are stated in both the VCE Mathematics Study Design 2016-2018 and some VCE Mathematics textbooks: Specialist…

are people that will disagree and say that the reason of evolution is because with time our species became more observant and gained knowledge and just knew that these things would work then they created them. I believe that this is completely wrong I think that there needs to be a theory then experiments, that is the only way for evolution to work. People believe that the basis of math is based off of assumptions. And I completely agree because assumptions and theories to me are synonyms.…

These things don't exist in math. Math is full of "rules" that don't have exceptions. Things such as the Pythagorean Theorem will always work for right triangles. There will never be a right triangle where a^2 + b^2 does not = c^2. This is what I like about math. Math is a subject that I think would never Let me down ; It has no contradictions. It's something that's reliable and useful. I've learned that without math, life would be a cycle of events without reason. If I ever wonder why when I…
