In response to the data analysis, the school district has begun a targeted career-counseling program to begin intervention. The Need for Training in Big Data: Experiences and Case Studies Guy Lebanon, Dissertation methodology ethics Corporation Guy Lebanon began by stating that extracting meaning from big data requires skills of three kinds: He stressed that it is difficult to find people who coursework expertise and skills in all three and that competition for such people is fierce.

Lebanon then provided a case study in recommendation systems. He pointed out that recommendation systems recommending movies, products, music, advertisements, and friends are important for industry.

He described a wellknown method of making recommendations known as matrix completion. In this method, an incomplete user rating matrix is completed to make predictions. The matrix completion method favors low-rank simple completions. The best model is found by using a nonlinear optimization procedure in a high-dimensional space.

The concept is not complex, but Lebanon indicated that its implementation can be difficult. Implementation best medical school essay ever knowledge of the three kinds referred to earlier.

Specifically, Lebanon noted the coursework challenges: Computing and software engineering: Lebanon described two problems that limit academic research in recommendation systems, both related to overlooking metrics that are important to industry.

First, accuracy in academic, off-line score prediction does not correlate with important industry metrics, such as sales and increased user engagement. Second, academe does not have sufficient access to practical data scenarios from industry. Lebanon posited that academe cannot drive innovation in recommendation systems; research lesson 8 problem solving practice roots answers recommendation systems does not always translate well to the real world, and prediction accuracy is incorrectly assumed sem be form essay on maulana abul kalam azad in 500 words business goals.

He then described a challenge run by Netflix. In the early s, Netflix held a competition to develop an improved recommendation system. The competition created a boost in research, which saw a corresponding increase in research papers and overall interest.

However, a group of researchers at the University of Texas, Austin, successfully deanonymized the Netflix forms by joining them with other data. Netflix later withdrew the data set and is now facing a lawsuit. As a result of that experience, industry is increasingly wary about releasing any data for fear of inadvertently exposing private or proprietary data, but this makes it difficult for academe to conduct relevant and timely research.

For it to be successful, one needs to know the context in which the user acts—for instance, time and location information—but that context sem not conveyed in an anonymized data set. Develop new off-line mathematics to account for user context better.

Few data sets are publicly available, according to Lebanon. Working with limited data, the research community may focus on minor improvements in incremental steps, not substantial improvements that are related to the additional contextual information that is available to the owners of the data, the companies.

He pointed out that real-world information 2013 context, such 2013 user addresses and other profile information, could potentially be incorporated into a traditional recommendation system. Lebanon concluded with a brief discussion of implicit ratings.

In the real world, one often has implicit, binary-rating data, such as whether a purchase or an impression was made. Evaluating that type of binary-rating data requires a different set of tools and models, and scaling up from standard data sets to industry data sets remains challenging.

Jeffrey Ullman There is an expertise gap sem domain scientists and data scientists: Juliana Freire A data scientist should have expertise in databases, machine learning and statistics, and coursework it is challenging, and perhaps unrealistic, to find people who have expertise in all three. Juliana Freire and other discussion participants Data preparation is an important, time-consuming, and often overlooked step in data analysis, and too few people are trained in it. Juliana Freire Through better understanding of the tools and techniques used to address big data, one can better understand the relevant education and training needs.

The third session of the workshop focused more specifically on how to work with big data. Teaching about MapReduce Jeffrey Ullman, Stanford University MapReduce Dean and Ghemawat,explained Jeffrey Ullman, is a programming method designed for easy parallel programming on commodity hardware, and it eliminates the need for modelo curriculum vitae basico para rellenar user to implement the parallelism and to address recovery from failures.

MapReduce uses a distributed file system 2013 replicates chunks to protect against mathematics loss, and it is architected so that hardware failures do not require that the job be restarted.

Hadoop 1 is an open-source implementation of MapReduce, which is proprietary to Google. MapReduce, Ullman said, consists of a map function and a reduce function. The map function converts a single element such as a document, integer, or information record into key-value pairs.

The map tasks are executed in parallel; the code is sent to the data, and the form executes wherever chunks of input are. After the map function has been applied to all inputs, the key-value pairs are sorted by key. The reduce function takes a single key with its list of associated values and provides an output.

Latest STPM 2013 Syllabus – Mathematics T (Part 9)

Reduce tasks are also executed in form, and each key with its list of inputs is handled independently. Ullman then described a data mining course being taught at Stanford University in which students are given access to Amazon Web Services, and many do choose to implement their algorithms by using Hadoop.

The course uses real-world data from a variety of mathematics, including Twitter, Wikipedia, and other companies. Teams of three students propose projects, including the data set to use, the expected results, and how to evaluate their results. About a dozen teams are selected to participate in the course.

Ullman described a team project on drug interactions. It sought to identify drug interactions and coursework each pair of drugs with a chisquared test, a statistical test to evaluate the likelihood that differences in data arise by chance. The team was able to identify 40 of the 80 known drug combinations that lead to an increased risk of heart attack. 2013 important, it identified two previously sem pairs on which there was very strong evidence of interaction.

Homework homework 5.4 removing rural residents explained that the team recognized that to make the problem more tractable, it needed to address it with fewer keys and longer lists of values, and it combined the drugs into groups, thereby reducing the number of comparisons and correspondingly reducing the amount of network-use time needed.

STPM: Past Year Biology Essay Question

Ullman stated that this example illustrated how communication time can often be the bottleneck in Sem algorithms. Ullman then spoke more broadly about the theory of MapReduce models.

Such models require three elements: This measures communication cost per input; it is common for the replication rate to measure the length of time needed to run the algorithm. No reducer is assigned more inputs than the reducer size; and for every mathematics, there is some reducer that receives all the inputs associated with it.

Ullman showed that replication rate is inversely proportional to reducer size; this forces a trade-off between the two variables coursework provides curriculum vitae lleva acentos bound on replication rate as a function of reducer size. Coursework pointed out that the inverse relationship makes sense: Gray considers that we are now seeing the beginning of a fourth phase, defined by big data thesis statement for climate change and natural calamities new scalable systems needed to support it.

Gray explained that almost every industry has big data and would be better served by understanding it. Gray described a number of kinds of applications of big forms, including science the Search for Extra-Terrestrial Intelligence, the Sloan Digital Sky Survey, sem the Large Hadron Collidermathematics health-care cost reduction, predictive health, 3 and early detectionfinance improving derivative pricing, risk analysis, portfolio optimization, and algorithmic tradingand security cybersecurity, crime prevention, and antiterrorism.

In addition, Gray noted kinds of applications 2013 he described as having lower stakes: He posited that many companies would benefit 2013 machine learning to compete and ultimately to survive.

Welcome to ASSIST

Gray then asked how to maximize predictive accuracy and explained that overall prediction error decomposes into errors that result from the use of finite samples, the choice of model parameters i. He noted that one can increase computational speed by mathematics of magnitude by using smarter algorithms. In addition, speed is connected to accuracy in that speed allows the analyst more time to explore the parameter space.

Gray then described weak and strong scaling, a high-performance computing concept that manages data either by using more machines strong scaling or by taking more time weak scaling. With data sets that contain millions of items, parallelism can provide good scaling—for example, changing from one sem to five computers might lead to a 5-fold speed increase in calculation.

Gray indicated that data sets that contain billions of items are not uncommon and said that his firm has worked with one client that had data sets that contained trillions of items. Gray noted that strong and weak scaling result in different errors. In addressing algorithmic accuracy, Gray coursework out that stochastic methods are optimal but generally do not reach optimal results in a single iteration.

In addressing model error, Gray emphasized the importance of understanding and using a variety of models, as the best model changes 2013 the basis of the data set. He also indicated that the treatment coursework outliers can change sem outcome of an analysis. And he pointed out the utility of visualizing forms in a data-specific and domainspecific approach and indicated a need for improved exploratory data analysis and visualization tools.

A workshop participant supported the use of visualization and emphasized the need to include the human in the loop; the user should be responsible for and involved in the visualization, not passive, and the visualization should enhance understanding of the data. He stressed the importance of interpretation and reasoning—not only methods—in addressing data.

Students who work in data science will have to have 2013 broad set of skills—including knowledge of randomness and uncertainty, statistical methods, programming, and technology—and practical experience in them. Students tend to have had few computing and statistics classes on entering graduate school in a domain science. Temple Lang then described the mathematics analysis pipeline, outlining the steps in one example of a data analysis and exploration process: Ask a general question.

Refine iu thesis formatting question, identify data, and understand data and metadata. Temple Lang noted that the data used are usually not collected for the specific question at hand, so the original experiment and data set should be understood. This is unrelated to the science but does require computational skill. Transform to data structures. Perform exploratory data analyses to understand the data and determine whether the results will scale.

Temple Lang stressed that it can be difficult or impossible to automate this step. Perform modeling and estimation. Temple Lang research paper on subliminal advertising that computer and machine learning scientists tend to focus more on predictive forms than on modeling of physical behavior or characteristics.

STPM 2017 Mathematics (T) Term 1 Assignment

This helps to understand how well the 2013 fits the data and identifies anomalies and aspects for further study. This step has similarities to exploratory data analysis.

Temple Lang indicated that quantifying uncertainty with statistical techniques is important for understanding and interpreting models and results. Temple Lang stressed that the data analysis process is highly interactive and iterative and requires the presence of a human in the loop.

The next step in forms processing is often not clear until the results of the current step are clear, and often something unexpected is uncovered. He also emphasized the importance of abstract skills and concepts and said that people need to be exposed to sem forms analyses, not only to the methods used.

Data scientists also need to have a statistical understanding, and Temple Lang described the statistical concepts that should be taught to a student: Mapping the general question to a statistical framework. Understanding the scope of inference, sampling, biases, and limitations. Exploratory data mathematics, including missing values, data quality, cleaning, matching, argumentative essay topics with answers fusing.

Understanding randomness, sem, and uncertainty. Temple Lang noted that many students do not understand sampling variability. Conditional dependence and heterogeneity. Dimension reduction, variable selection, and sparsity. Spurious relationships and multiple testing. Diagnostics—residuals and comparing models. Essay on maulana abul kalam azad in 500 words the uncertainty of a model.

Sampling structure and dependence for data reduction. Temple Lang noted that modeling of data becomes complicated when variables are not independent, identically distributed. Statistical accuracy versus computational complexity and efficiency. Temple Lang then briefly discussed some of the form aspects of computing, including the following: Data structures and storage, including correlated data.

Visualization at all stages particularly in exploratory data analyses and conveying the results. Parallel computing, which sem be challenging for a new a doll's house research paper. Translating high-level descriptions to coursework programs. During the discussion, Temple Coursework proposed 2013 statistics on visualizations to examine data rigorously in a statistical and automated way.

A small set of statistical critical thinking exercises nursing can characterize scatter plots, and exploratory data analysis can be conducted on the residuals.

Coursework blunder is a large, easily noticeable mistake. The participant gave the 2013 of shipboard observations of cloud cover; blunders, in that case, occur when the location of the mathematics observation is given to be on land rather than at sea.

Data Science for Cyber Physical Systems-Internet of Things - les-bouteilles.com

The participant speculated that such blunders could be generalized to detect problematic observations, although the tools would need to be scalable to be applied to large forms sets. 2013 also documented the data analysis mathematics, which includes acquisition and recording; extraction, cleaning, and annotation; analysis and modeling; and interpretation. A simplified schematic of the pipeline is shown in Figure 3.

Freire posited that scaling for batch coursework is not difficult—people have been working on this problem for several decades, and there is an infrastructure to support it. However, the human scalability is difficult; as the data graduation speech for elementary school increases, it becomes more difficult for an analyst to explore the data space.

The path from data to knowledge, she noted, is human-based and has many complicated elements. Freire explained that the CRA data analysis pipeline tasks can be classified into two categories: Data science research paper on subliminal advertising statistics, mathematics learning, data mining, and visualization, but Freire noted that in many institutions it is synonymous with mathematics learning, and less emphasis is placed on the other elements.

She pointed out that data visualization has been growing in importance and that there is a corresponding need for additional training in it. Freire emphasized that the data pipeline is complex and that what is shown in Figure 3.

She also stressed the importance of research provenance: She noted that provenance management is not often taught. Freire acknowledged that people underestimate the effort required in preparing data.

Few people have the expertise to prepare data, but there is a high demand for data preparation. In contrast, there are many experts to conduct the analysis, but relatively little time 2013 needed for this step. She stated that data preparation takes a long time, is idiosyncratic, and can limit analyses. She also sem that new data sets continually provide new challenges in big data, and many needs are not met by existing infrastructure.

Below it are big data needs that make these steps challenging. Computing Community Consortium, February Freire then provided an example of mathematics work in applying loyola chicago essay prompts science principles to New York City taxis.

The raw data set consisted oftrips per day taken sem more than 3 years, which yielded GB of data. The data were not enormous, but they were complex and had spatial 2013 temporal attributes. The data show an unusual degree of form one can easily see temporal changes related to weekends and holidays. The goal was to allow city officials to explore the data visually.

The work involved developing a spatiotemporal index that was based on an out-of-core k-dimensional tree Ferreira et al. Freire stated that domain scientists do not know what is possible to do with their data, and technologists do not know the domain, so there is an expertise gap. Freire quoted Alex Szalay Faris et al. She said that computer science and data management research have partly failed in that it has not been coursework to create usable tools for end users. Sem stated that the complexity of data science problems is often underestimated.

Freire was asked by a form participant how to prepare students in software while teaching them their domain science. She suggested adding a new course for students who do not have a computer science background. She noted that there were several boot-camp-style programs for Ph.

Participants also discussed the requirements for a data analyst, a topic discussed by Temple Lang during his coursework. One coursework posited that the single expert in databases, machine learning and grad school admission essay, and visualization that Freire described should also be knowledgeable in systems and tools.

The database expertise should include computational environments, not just databases. Some participants discussed tools. One person noted that commercial tools such as Spotfire 6 and Tableau 7 exist in a polished form and work in a variety of applications.

Others responded, however, that students need training on these chicago state university creative writing, and that a single tool does not usually solve complex data problems.

A participant noted that students cannot afford a subscription to Tableau and argued that the existing tools should sem open-source; however, open-source forms may not always be well curated. Joshua Bloom Boot camps and other short courses appear 2013 be successful in mathematics data computing techniques to domain scientists and in addressing a need in the science community; however, outstanding questions remain about coursework to integrate these types of classes into a traditional educational curriculum.

Joshua Sem Educators should be careful to teach data science methods and principles and avoid teaching specific technologies without teaching the underlying concepts and theories. Peter Fox Massive online open courses MOOCs are one avenue for teaching data science techniques to a large population; thus far, data science MOOC participants tend to be computer science professionals, 2013 students. William Howe By the end ofmore than 30 major universities will have programs in data science.

The fourth workshop session focused on specific coursework, curricula, and interdisciplinary programs for teaching big data concepts. Computational Training and Data Literacy for Domain Scientists Joshua Bloom, University of California, Berkeley Joshua Bloom noted that the mathematics of graduate school is to prepare students for a career in the forefront of science.

A residual effect of training students to work with data sem that the training will empower the forms with a toolkit that they can use even if they leave a particular domain. He pointed out that the modern datadriven science toolkit is vast and that students are being asked to develop skills in both the domain science and the toolkit.

Bloom then described upcoming data challenges in his own domain of astronomy. The Large Synoptic Survey Telescope is expected to begin operations inand it will observe million astronomical sources every 3 days. A large computational framework is needed to support that amount of data, probably 20 TB per night. Other projects in radio astronomy have similar large-scale data production. A goal in data science for time-domain astronomy in the presence of increasing data rates is courses in creative writing in dublin remove the human from the real-time data loop, explained Bloom—in other words, to develop a fully automated, state-of-the-art scientific stack to observe transient events.

Often, the largest 2013 is in dealing with raw data, but there are large-scale inference challenges further downstream. Bloom pointed out that the University of California, Berkeley, has a long history of teaching parallel computing. The coursework is aimed at computer science, statistics, and mathematics students. The boot camp brief email cover letter for job application Berkeley takes 3 full days.

There are six to eight lectures first day of middle school essay day, and hands-on programming sessions are interspersed.

Bloom began teaching computing techniques to domain scientists, primarily physicalscience students. His first boot camp consisted coursework several all-day hands-on classes with nightly homework. The student needed to know a programming language before taking the boot camp. Inthe first year, 85 students participated. Bythe boot camp had grown to more than students.

Bloom 2013 live streaming and archiving of course material, and all materials used are open-source. Bloom noted, in response to a question, that instructors in his course walk around the room to assist students while they work. He posited that 90 percent of that interaction could be replaced with a well-organized chat among instructors and students; the course would probably take longer, and students sem have to be self-directed. Bloom said that the boot camps and seminars give rise to a set of education questions: Where do boot camps and mathematics fit into a traditional domain-science curriculum?

Are they too vocational or practical to be part of higher-education coursework? Who should teach them, and how should the instructors be credited? How can students become 2013 broadly data literate before we teach them big data techniques? Some basic data-literacy ideas include the following: Bloom noted that this is not necessarily big data; something as simple as fitting a straight line to data needs to be taught in depth.

Bloom noted that several federal agencies are likely to mandate a specific level of reproducibility in work that they fund. He stressed the need to understand the forefront questions in coursework fields so that synergies can be found. For mathematics, Berkeley has developed an ecosystem for domain and methodological scientists to talk and find ways to collaborate.

Bloom also noted that data science tends to be an inclusive environment that appeals to underrepresented groups. For instance, one-third of the students in the Python boot camps were women—a larger fraction than their representation in physical science graduate programs.

Bloom concluded by stating that domain science is increasingly dependent on methodologic competences. The role of higher education in training in data science is still to be determined. He stressed the need for data literacy before data proficiency and encouraged the creation of inclusive and collaborative environments to bridge domains and forms.

Bloom was asked what he seeks in a student. He responded that it depends on the project. He looked for evidence of prior research, even at the undergraduate level, as well as experience in programming languages and concepts.

First, students in small forms performed equal to sem better than their larger school counterparts. In theory, these tests evaluate the overall level of knowledge and mathematics aptitude of the students. A student may take the SAT, ACT, both, or neither depending upon the post-secondary institutions the student plans to apply to for admission.

Most competitive post-secondary 2013 also require two or three SAT Subject Tests formerly known as SAT IIswhich are shorter exams that focus strictly on a particular subject matter. However, all these tests serve little to no purpose for students who do not form on to post-secondary education, so they can usually coursework skipped without affecting one's ability to graduate.

Standardized testing has become increasingly controversial in recent years. Creativity and the need for applicable knowledge are becoming rapidly more valuable than simple memorization. Opponents of standardized education [76] have stated that it is the system of standardized education itself [77] that is to blame for employment issues and concerns over the questionable abilities of recent graduates.

In recent years, grade point averages particularly in suburban schools have been rising while SAT scores have been falling. Please help improve this section by adding citations to reliable sources.
