Data science, which should not be mistaken for information science, is a field of study that uses scientific processes, methods, systems, and algorithms to extract insights and knowledge from various forms of data, be it structured or unstructured. It is similar to data mining and is a conception to unify machine learning, data analysis, statistics, and their related methods so as to analyze and understand the actual facts about data. Data science employs theories and techniques taken from many disciplines such as computer science, information science, statistics, and mathematics.

In a nutshell, data science can be said to be a multidisciplinary blend of algorithm development, data inference, and technology in a way to find solution to analytically complex problems. Data science is useful to anyone who wants to be a data miner.

    I'm a machine learning engineer. I stumble upon many exciting papers. Most of those papers are in the ML and algorithmics fields and are based on many mathematics. I'm interested in strengthening mainly my math skills, primarily by reading papers and books in the field. I'm looking for a tutor for 2-3 sessions a week, 2 hours each session. That means around 20 hours a month. *** If you have: *** * AT LEAST Master's degree in Math / CS AND * Strong applied mathematics background, mainly in math related to ML AND * AT LEAST moderate computer science knowledge Please contact me, leave a price offer, have let's chat! :)

    Quiero saber el valor de los datos de las personas en paises "del tercer mundo". Voy a desarrollar una aplicación gratuita y una de las vias de ingresos puede ser la venta de los datos de los usuarios que se descarguen la aplicación, pero tengo que saber con exactitud cuánto valen los datos de esas personas. Valen más los datos de las personas del primer mundo que las del tercer mundo? cual es la diferencia? Necesito datos concretos y fuentes de donde hayan salido. Gracias

    Write solutions to my 18 questions of Data Science & Statistics assignment (a few questions requires Python) (Find the complete assignment in the attachment below) For EXAMPLE: Bayesian Regression/markov chain 1 GENERAL REGRESSION PROBLEM In the Bayesian viewpoint, we formulate linear regression using probability distributions rather than point estimates. The response, y, is not estimated as a single value, but is assumed to be drawn from a probability distribution. The model for Bayesian Linear Regression with the response sampled from a normal distribution is: The output, y is generated from a normal (Gaussian) Distribution characterized by a mean and variance. The mean for linear regression is the transpose of the weight matrix multiplied by the predictor matrix. The varian...
