explain the applications of all statistical features in computer science

Descriptive statistics are used to describe the total group of numbers. SPSS offers the ability to easily compile descriptive statistics, parametric and non-parametric analyses, as well as graphical depictions of results through the graphical user interface (GUI). For the effective functioning of the State, Statistics is indispensable. In: Du Z. Machine learning has a greater emphasis on large scale applications and prediction accuracy. There are many more distributions that you can dive deep into but those 3 already give us a lot of value. You can find statistics just about anywhere. — — If you would like to follow my work on Recommendation Systems, Deep Learning, MLOps, and Data Science Journalism, you can check out my Medium and GitHub, as well as other projects at https://jameskle.com/. The cube represents our dataset and it has 3 dimensions with a total of 1000 points. Connect with me on LinkedIn too! One of the most important applications of statistical analysis is in designing … These developments have given rise to a new research area on the borderline between statistics and computer science. The use of computer technologies is also commonplace in all types of organizations, in academia, research, industry, government, private and business organizations. They are made with user-friendly interfaces for easy use. UNIT-VI Do body weight calorie intake, fat intake, and participant age have an influence on heart attacks (Yes vs No)? An Explanation of Bootstrapping . The best fit is done by making sure that the sum of all the distances between the shape and the actual observations at each point is as small as possible. For example, after exploring a dataset we may find that out of the 10 features, 7 of them have a high correlation with the output but the other 3 have very low correlation. Predict whether someone will have a heart attack on the basis of demographic, diet and clinical measurements. What’s so Special About Waterfall Charts? The group of algorithms highly relevant for computational statistics from computer science is machine learning, artificial intelligence (AI), and knowledge discovery in data bases or data mining. Statistical features is probably the most used statistics concept in data science. In the game industry where focus and interactivity are the key players, computer graphics helps in providing such features in the efficient way. Machine learning has the upper hand in Marketing! The median is the mid-point in a distribution of values among cases, with an equal number of cases above and below the median. Understand thatthere are boolean and logical expressions that can be evaluated in the sameway. The most common stats technique used for dimensionality reduction is PCA which essentially creates vector representations of features showing how important they are to the output i.e their correlation. How does the probability of getting lung cancer (Yes vs No) change for every additional pound of overweight and for every pack of cigarettes smoked per day? Applications are made in a machine-understandable language to accomplish a variety of individual or organizational jobs. Different department and authorities require various facts and figures on different matters. But the distinction has become and more blurred, and there is a great deal of “cross-fertilization.”. Speed. The fit of the shape is “best” in the sense that no other position would produce less error given the choice of shape. If we see a Gaussian Distribution we know that there are many algorithms that by default will perform well specifically with Gaussian so we should go for those. Data mining processes for computer science have statistical co… The group of algorithms highly relevant for computational statistics from computer science is machine learning, artificial intelligence (AI), and knowledge discovery in data bases or data mining. Resampling generates a unique sampling distribution on the basis of the actual data. One has to understand the simpler methods first, in order to grasp the more sophisticated ones. Capabilities of Computer System. His research areas include nonparametric inference, asymptotic theory, causality, and applications to astrophysics, bioinformatics, and genetics. A basic visualisation such as a bar chart might give you some high-level information, but with statistics we get to operate on the data in a much more information-driven and targeted way. They are made with user-friendly interfaces for easy use. As computers become even more pervasive, the potential for computer-related careers will continue to grow and the career paths in computer-related fields will become more diverse. Truthfully, some data science teams purely run algorithms through python and R libraries. We cover almost all topics and subjects related to computer science and will help you understand key concepts and issues. Examples would be games, word processors (such as Microsoft Word), and media players. • In a table format, describe the programming features available in R. o Explain how they are useful in analyzing big datasets. for the formation of suitable military and fiscalpolicies. One of the most popular options to get started with a career in Information Technology, the course gives you an insight into the world of computers and its applications. With feature pruning we basically want to remove any features we see will be unimportant to our analysis. Applications of Statistics. Dimension reduction reduces the problem of estimating p + 1 coefficients to the simple problem of M + 1 coefficients, where M < p. This is attained by computing M different linear combinations, or projections, of the variables. The Bureau of Labor Statistics (BLS) projects computer science research jobs will grow 19% by 2026. It is typically too expensive or even impossible to measure this directly. Computer Platform Defined. Jurimetrics is the application of probability and statistics to law. He is also a member of the Center for Automated Learning and Discovery in the School of Computer Science. The scientific method, used in science projects, contains several steps. The P(E|H) in our equation is called the likelihood and is essentially the probability that our evidence is correct, given the information from our frequency analysis. If I told you the die is loaded, can you trust me and say it’s actually loaded or do you think it’s a trick?! Compare the statistical features of R to its programming features. The Statistical Package for the Social Sciences (SPSS) is a software package used in statistical analysis of data. In other words, the method of resampling does not involve the utilization of the generic distribution tables in order to compute approximate p probability values. These involve stratifying or segmenting the predictor space into a number of simple regions. Check out the graphic below for an illustration. Hands-on real-world examples, research, tutorials, and cutting-edge techniques delivered Monday to Thursday. In data science this is commonly quantified in the range of 0 to 1 where 0 means we are certain this will not occur and 1 means we are certain it will occur. Machine learning is the subfield of computer science that formulates algorithms in order to make predictions from data. Thanks for the overwhelming response! one of the most popular Medium posts on machine learning, More from Cracking The Data Science Interview, Early results: This is what happens when you machine-learn JIRA tickets, Police, Antifa, and Gender: Word Frequency Analysis of the Coverage of #BlackLivesMatter Protests. Statistical learning emphasizes models and their interpretability, and precision and uncertainty. The min and max values represent the upper and lower ends of our data range. allow us to give instructions to a computer in a language the computer understands In layman’s terms, it involves finding the hyperplane (line in 2D, plane in 3D and hyperplane in higher dimensions. We did a lot of exercises on Bayesian Analysis, Markov Chain Monte Carlo, Hierarchical Modeling, Supervised and Unsupervised Learning. The data points that kind of “support” this hyperplane on either sides are called the “support vectors”. Use it whenever you feel that your prior data will not be a good representation of your future data and results. Ideas from statistics, theoretical computer science, and mathematics have provided a growing arsenal of methods for machine learning and statistical learning theory: principal component analysis, nearest neighbor techniques, support vector machines, Bayesian and sensor networks, regularized learning, reinforcement learning, sparse estimation, neural networks, kernel methods, tree-based methods, the bootstrap, boosting, association rules, hidden Markov models, and independent component … Identify the risk factors for prostate cancer. It’s all fairly easy to understand and implement in code! The book is ambitious. Education: In the game industry where focus and interactivity are the key players, computer graphics helps in providing such features in the efficient way. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computers. The class covers expansive materials coming from 3 books: Intro to Statistical Learning (Hastie, Tibshirani, Witten, James), Doing Bayesian Data Analysis (Kruschke), and Time Series Analysis and Applications (Shumway, Stoffer). Aside: The NP-Complete problem. Computer graphics finds a major part of its utility in the movie industry and game industry. The two best-known techniques for shrinking the coefficient estimates towards zero are the ridge regression and the lasso. It’s often the first stats technique you would apply when exploring a dataset and includes things like bias, variance, mean, median, percentiles, and many others. The mode is the value that occurs most often in the distribution. When we begin with a sample and then try to infer something about the population, we are using inferential statistics.In working with this area of statistics, the topic of hypothesis testing arises. (2013) Computer Application in the Statistical Work. Other areas where statistics are use in computer science include vision and image analysis, artificial intelligence and network and traffic modeling. Take a look, Python Alone Won’t Get You a Data Science Job.
