By Leah Betancourt Information posted publicly on blogs, Facebook , Twitter , forums and other sites is fair game. It is yet another reminder that people need to be aware of what they are posting on social networking sites and to whom they’re connected. Jules Polonetsky, director and co-chair of the Future of Privacy Forum , said online users have no clue that a comment they made on a blog is being added to a database for some unknown use. He said the Federal Trade Commission is right now re-examining the current privacy structure in the U. But at the same time, he said consumers are always very comfortable with Amazon using data to recommend books they might like. Personal finance reporter Erica Sandberg , who covered the issue of social media datamining in a story for CreditCards. Sandberg said this is just more information anyone can use to help them make a decision. Entities such as airlines, politicians, and even non-profits can use this data for finding new customers or targeting products to existing ones.

A former Cambridge Analytica employee says the firm used “information dominance” to spread fake news ABC News Facebook under investigation US and European politicians have demanded an explanation of how Cambridge Analytica improperly accessed data in and why Facebook failed to inform its users.
Data mining is the process of finding anomalies, patterns and correlations within large data sets to predict outcomes. Using a broad range of techniques, you can use this information to increase revenues, cut costs, improve customer relationships, reduce risks and more.
Collections of databases that work together are called data warehouses. This makes it possible to integrate data from multiple databases. Data mining is used to help individuals and organizations make better decisions. Data Warehouses A database consists of one or more files that need to be stored on a computer. In large organizations, databases are typically not stored on the individual computers of employees but in a central system.
This central system typically consists of one or more computer servers. A server is a computer system that provides a service over a network. The server is often located in a room with controlled access, so only authorized personnel can get physical access to the server. In a typical setting, the database files reside on the server, but they can be accessed from many different computers in the organization.
As the number and complexity of databases grows, we start referring to them together as a data warehouse. A data warehouse is a collection of databases that work together. A data warehouse makes it possible to integrate data from multiple databases, which can give new insights into the data. The ultimate goal of a database is not just to store data, but to help businesses make decisions based on that data.

There are, however, other predictors that have many more distinct values and can create a much more complex histogram. Consider, for instance, the histogram of ages of the customers in the population. In this case the histogram can be more complex but can also be enlightening. Consider if you found that the histogram of your customer data looked as it does in figure 1.
Data mining is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.
Welcome to Jason Frand’s Homepage September 1, was the start of an entirely new career for me. Retiring in meant it was thirty years since completing my doctorate and having lived an incredible career at UCLA involving the future: That career was my trip to the moon! Now I’m on a trip to Mars! Retiring I turned my time and energy toward doing something I really enjoy doing: As a bonus, I was invited to write a book about how to teach math problem solving.
My on-going life as a husband, father, grandfather and community member Travels with Lois and Jason catalogs many of the wonderful travel adventures we’ve shared together since our honeymoon camping trip across the US. The poem The Owl’s Answer in many ways summarizes my views toward life, and learning as the greatest journey which we can experience. Year One Experiences describes the chaos in my life as a doctoral student, but still rings true after all these years. My retired life as a Math coach In October , I started teaching Math Olympiad enrichment classes twice each week to 4th and 5th grade students at Linwood E.
Howe Elementary, a Title 1 school that serves a broad cross section of eastern Culver City. Retirement could not be more fun!!! The book was the next step in a journey, in large part with my friend and collaborator Ruth Sabean, through the world of mathematical teaching and programs.

Drill down to Boston. The user forms a hypothesis about a relationship and verifies it or discounts it with a series of queries against the data. For example, an analyst might hypothesize that people with low income and high debt are bad credit risks and query the database to verify or disprove this assumption. Data mining can be used to generate an hypothesis. For example, an analyst might use a neural net to discover a pattern that analysts did not think to try – for example, that people over 30 years old with low incomes and high debt but who own their own homes and have children are good credit risks.
How Data Mining Works How is data mining able to tell you important things that you didn’t know or what is going to happen next? That technique that is used to perform these feats is called modeling. Modeling is simply the act of building a model a set of examples or a mathematical relationship based on data from situations where the answer is known and then applying the model to other situations where the answers aren’t known. Modeling techniques have been around for centuries, of course, but it is only recently that data storage and communication capabilities required to collect and store huge amounts of data, and the computational power to automate modeling techniques to work directly on the data, have been available.
As a simple example of building a model, consider the director of marketing for a telecommunications company. He would like to focus his marketing and sales efforts on segments of the population most likely to become big users of long distance services.

So why is online dating still such a thoroughly imperfect experience? Amy Webb, like so many others, learned just how flawed the science of online dating is by going on a series of comically awkward dates with some pretty unbelievable characters. In her book, Data, A Love Story: Set up a profile, upload a few photos that happen to be sitting on your hard drive, and fill out some personal info. The difference, of course, is that dating sites have an objective far more specific than an aimless timesuck like Facebook.
Webb kicked off her digital quest for a mate by listing 72 traits she wanted her future partner to possess, which is how she recommends online dating newbies get started. Her initial brainstorm included everything from personal habits and marital history to work ethic and Mac vs.

Underground mining hard rock and Underground mining soft rock Mantrip used for transporting miners within an underground mine Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to the surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, the extraction method or the technique used to reach the mineral deposit.
Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques. Other methods include shrinkage stope mining , which is mining upward, creating a sloping underground room, long wall mining , which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room.
OkCupid’s matching engine uses that data to calculate a couple’s compatibility. The closer to percent—mathematical soul mate—the better. Dating with his computer-endowed profiles was a.
