Data Science: Overviews


Quick Fact About Data Mining

#artificialintelligence

As our world digitizes, information becomes more valuable. The excess of information and the rapid increase of the data causes the stored data to become polluted and unusable. I would like to start with an example in order to understand this science which is one of the new professions of the modern century more easily. Suppose that an automobile company that produces luxury sports cars is launching a new, very fast, single-door convertible, the company will naturally think who its potential customers are. Nerd IT staff working in the company have a new idea.

Data Analytics: Past, Present and Future

#artificialintelligence

The desire to look into the future is as old as humanity itself. From wanting to know where the next meal is coming from to placing bets on the Grand National – a view of the future has an obvious attraction. Nowadays, businesses are turning from witchcraft and wizardry and looking to something a little more scientific. They want to figure out what is to come and give themselves an edge. New technologies like artificial intelligence, machine learning and cognitive systems, coupled with the promise of Big Data are creating the illusion that all questions can be answered – even those which pertain to the future.


Artificial Intelligence In The Workplace: How AI Is Transforming Your Employee Experience 7wData

#artificialintelligence

Soon, even those of us who don't happen to work for technology companies (although as every company moves towards becoming a tech company, that will be increasingly few of us) will find AI-enabled machines increasingly present as we go about our day-to-day activities. From how we are recruited and on-boarded to how we go about on-the-job training, personal development and eventually passing on our skills and experience to those who follow in our footsteps, AI technology will play an increasingly prominent role. Here's an overview of some of the recent advances made in businesses that are currently on the cutting-edge of the AI revolution, and are likely to be increasingly adopted by others seeking to capitalize on the arrival of smart machines. Before we even set foot in a new workplace, it could soon be a fact that AI-enabled machines have played their part in ensuring we're the right person for the job. AI pre-screening of candidates before inviting the most suitable in for interviews is an increasingly common practice at large companies that make thousands of hires each year, and sometimes attract millions of applicants.

Artificial intelligence (AI) is quickly changing just about every aspect of how we live our lives, and our working lives certainly aren't exempt from this. Soon, even those of us who don't happen to work for technology companies (although as every company moves towards becoming a tech company, that will be increasingly few of us) will find AI-enabled machines increasingly present as we go about our day-to-day activities. From how we are recruited and on-boarded to how we go about on-the-job training, personal development and eventually passing on our skills and experience to those who follow in our footsteps, AI technology will play an increasingly prominent role.

Adaptive Model Selection Framework: An Application to Airline Pricing

arXiv.org Machine Learning

Multiple machine learning and prediction models are often used for the same prediction or recommendation task. In our recent work, where we develop and deploy airline ancillary pricing models in an online setting, we found that among multiple pricing models developed, no one model clearly dominates other models for all incoming customer requests. Thus, as algorithm designers, we face an exploration - exploitation dilemma. In this work, we introduce an adaptive meta-decision framework that uses Thompson sampling, a popular multi-armed bandit solution method, to route customer requests to various pricing models based on their online performance. We show that this adaptive approach outperform a uniformly random selection policy by improving the expected revenue per offer by 43% and conversion score by 58% in an offline simulation.


Which principal components are most sensitive to distributional changes?

arXiv.org Machine Learning

It is popular to use principal component analysis (PCA) for anomaly detection and stochastic process control (SPC). Using PCA in SPC goes back to the work of Jackson and Morris (1957) and Jackson and Mudholkar (1979), and its various extensions (see Ketelaere, Hubert, and Schmitt (2015) and Rato et al. (2016) for an overview) have been succesfully applied to many real data situations. Within the machine learning litterature on anomaly detection, Mishin et al. (2014) use PCA for temperature monnitoring at Johns Hopkins, Harrou et al. (2015) apply PCAbased anomaly detection to find segments with abnormal rates of patient arrivals at an emergency department, and Camacho et al. (2016) relate PCA-based monitoring in SPC with modern anomaly detection in statistical networks. Pimentel et al. (2014) provide an extensive review of novelty detection techniques and applications, and it is pointed to PCA being very useful for detecting outliers in this setting, for a large range of real world examples, covering industrial monitoring, video surveilance, text mining, sensor networks and IT security. In this review, as well as in Lakhina, Crovella, and Diot (2004) and Huang et al. (2007), it is acknowledged that it is most often the residual subspace of PCA that is most useful for outlier detection.


A Clinical Approach to Training Effective Data Scientists

arXiv.org Artificial Intelligence

Like medicine, psychology, or education, data science is fundamentally an applied discipline, with most students who receive advanced degrees in the field going on to work on practical problems. Unlike these disciplines, however, data science education remains heavily focused on theory and methods, and practical coursework typically revolves around cleaned or simplified data sets that have little analog in professional applications. We believe that the environment in which new data scientists are trained should more accurately reflect that in which they will eventually practice and propose here a data science master's degree program that takes inspiration from the residency model used in medicine. Students in the suggested program would spend three years working on a practical problem with an industry, government, or nonprofit partner, supplemented with coursework in data science methods and theory. We also discuss how this program can also be implemented in shorter formats to augment existing professional masters programs in different disciplines. This approach to learning by doing is designed to fill gaps in our current approach to data science education and ensure that students develop the skills they need to practice data science in a professional context and under the many constraints imposed by that context.

How AI and Big Data are Improving Research Results Qualtrics

#artificialintelligence

Market research is a $44.5 B market and growing. Online research is among the fastest growing parts of the market thanks to the pervasiveness of the web and the ease with which we can now collect data. However, as the world conducts more and more survey research, the issues that we see elsewhere with big data are now affecting the survey research industry as well, specifically the issue of data quality. Thanks to the growth in online survey research, billions of survey responses are collected every year. But 1/4th of those responses are of poor quality[1].
