Advanced Statistics and Data Mining for Data Science


Data Science is an ever-evolving field. Data Science includes techniques and theories extracted from statistics, computer science, and machine learning. This video course will be your companion and ensure that you master various data mining and statistical techniques. The course starts by comparing and contrasting statistics and data mining and then provides an overview of the various types of projects data scientists usually encounter. You will then learn predictive/classification modeling, which is the most common type of data analysis project.

Demystifying Machine Learning: An Overview


Have you ever had a credit card transaction declined when it shouldn't have been? Or been on the receiving end of a personalized email or web ad? Have you ever noticed a site giving you recommendations for things you might be interested in when you're shopping online? And my last example, have you ever had an offer from a company designed to stop you from leaving them as a customer? If any of these things have happened to you, then you've probably been on the receiving end of a machine learning algorithm, employed by a company you do business with (or in some cases, have merely considered doing business with). We're going to take you behind the scenes and give you a layman's view of machine learning so you can see what kind of problems they can solve.

Amazon Machine Learning and Analytics Tools – BMC Blogs


Here we begin our survey of Amazon AWS cloud analytics and big data tools. First we will give an overview of some of what is available. Then we will look at some of them in more detail in subsequent blog posts and provide examples of how to use them. Amazon's approach to selling these cloud services is that these tools take some of the complexity out of developing ML predictive, classification models and neural networks. That is true, but could it be limiting.

A Guide to Basic Data Analysis Geckoboard


As the head of customer support, you notice a significant increase in ticket response time and you need to know what's causing it. Perhaps you're the marketing manager for a SaaS company and see that signup numbers have dipped. The CEO and VP of product want to know the cause. Maybe your first task of the day is figuring out why the average cart abandonment rate for your ecommerce business is increasing. Or suppose the activation rate for your mobile app has decreased and you're responsible for figuring out why. Whatever the problem, figuring out what caused it and how to fix it is now your top priority. You already know data can help solve the problem, but you don't have the time or expertise for a massively complex data investigation. You don't have to be a statistician or have unlimited time to solve your most pressing business problems using data. This no nonsense data analysis guide will help you confidently draw conclusions and make smart, data-backed decisions. Leaders need to focus on intelligently sifting through the massive amounts of available information to retrieve knowledge that is actionable, and to use effective processes and tools to make smart decisions. Before diving into any kind of data analysis, you should quickly validate the problem you've identified. The single most critical principal I apply when analyzing data is a rule my high school math professor taught me at age 14: 'Don't write the first line of code until you can describe in plain English the problem you are attempting to solve!' Simply put, if you can't explain in plain english the business problem you are setting out to address, no amount of data analytics is ever going to solve it.

The power of Artificial Intelligence in manufacturing - The Manufacturer


Just as manufacturing has seen huge benefits from Lean, automation and advanced IT, Artificial Intelligence promises to be the next breakthrough in productivity improvement. Artificial Intelligence (AI) has the potential to enhance and extend the capabilities of humans, and help businesses achieve more, faster and more efficiently. Though by no means a new concept, several more recent developments have enabled AI to cross into the mainstream: namely, cloud computing, big data, and improved machine learning algorithms. AI-driven analytics and real-time insights have already begun to help businesses grow their revenues and market shares faster than their peers in industries as diverse as healthcare, finance, utilities and ecommerce. The Manufacturer's Annual Manufacturing Report 2018 found that 92% of senior manufacturing executives believe that'Smart Factory' digital technologies – including Artificial Intelligence – will enable them to increase their productivity levels and empower staff to work smarter.

A Framework for Approaching Textual Data Science Tasks


There's an awful lot of text data available today, and enormous amounts of it are being created on a daily basis, ranging from structured to semi-structured to fully unstructured. What can we do with it? Well, quite a bit, actually; it depends on what your objectives are, but there are 2 intricately related yet differentiated umbrellas of tasks which can be exploited in order to leverage the availability of all of this data.

Selecting the best system, large deviations, and multi-armed bandits Machine Learning

Consider the problem of finding a population amongst many with the largest mean when these means are unknown but population samples can be generated via simulation. Typically, by selecting a population with the largest sample mean, it can be shown that the false selection probability decays at an exponential rate. Lately researchers have sought algorithms that guarantee that this probability is restricted to a small $\delta$ in order $\log(1/\delta)$ computational time by estimating the associated large deviations rate function via simulation. We show that such guarantees are misleading. Enroute, we identify the large deviations principle followed by the empirically estimated large deviations rate function that may also be of independent interest. Further, we show a negative result that when populations have unbounded support, under mild restrictions, any policy that asymptotically identifies the correct population with probability at least $1-\delta$ for each problem instance requires more than $O(\log(1/\delta))$ samples in making such a determination in any problem instance. This suggests that some restrictions are essential on populations to devise $O(\log(1/\delta))$ algorithms with $1 - \delta$ correctness guarantees. We note that under restriction on population moments, such methods are easily designed. We also observe that sequential methods from stochastic multi-armed bandit literature can be adapted to devise such algorithms.
