Entropy Based Feature Selection Welcome! This workshop is from Winder.ai. Sign up to receive more free workshops, training and videos. One simple way to evaluate the importance of features (something we will deal with later) is to calculate the entropy for prospective splits. In this example, we will look at a real dataset called the “mushroom dataset”. It is a large collection of data about poisonous and edible mushrooms. Attribute Information: (classes: edible=e, poisonous=p) 1.

Data Cleaning Example - Loan Data Welcome! This workshop is from Winder.ai. Sign up to receive more free workshops, training and videos. A huge amount of time is spent cleaning, removing, scaling data. All in an effort to squeeze a bit more performance out of the model. The data we are using is from Kaggle, and is available in raw from from here. You will need to sign into kaggle if you want to download the full data.

Root Cause Analysis: The 5-Whys Deciding what problem you should try and solve is one of the hardest steps to get right in Data Science. If you get it wrong, then you’ll spend significant amounts of time free wheeling around the rest of the data science process and end up with something that nobody wants or cares about. There is nothing worse that someone suggesting that your work has no value.

Probability Distributions Welcome! This workshop is from Winder.ai. Sign up to receive more free workshops, training and videos. This workshop is about another way of presenting data. We can plot how frequent observations are to better characterise the data. Imagine you had some data. For sake of example, imagine that is a measure of peoples’ height. If you measured 10 people, then you would see 10 different heights. The heights are said to be distributed along the height axis.

Why do we use Standard Deviation?

Why do we use Standard Deviation and is it Right? It’s a fundamental question and it has knock on effects for all algorithms used within data science. But what is interesting is that there is a history. People haven’t always used variance and standard deviation as the defacto measure of spread. But first, what is it? Standard Deviation The Standard Deviation is used throughout statistics and data science as a measure of “spread” or “dispersion” of a feature.

Mean and Standard Deviation

Mean and Standard Deviation Welcome! This workshop is from Winder.ai. Sign up to receive more free workshops, training and videos. This workshop is about two fundamental measures of data. I want to you start thinking about how you can best describe or summarise data. How can we best take a set of data and describe that data in as few variables as possible? These are called summary statistics because they summarise statistical data.

Research-Driven Development: Improve the Software You Love While Staying Productive

Slides Abstract Have you ever wondered which parts of your job you love or hate? Chances are that like most developers you love learning and new problems to solve. You hate monotony and bureaucracy. You’ve probably put strategies in place to mitigate the things you don’t like. An anarchic development process like Agile, to reduce the amount of time in meetings. But have you ever thought about the way in which you approach learning and problem solving?

What is Artificial Intelligence?

If you ask anyone what they think AI is, they’re probably going to talk about sci-fi. We sometimes even need to set the record straight during our AI consulting projects. Science fiction has been greatly influenced by the field of artificial intelligence, or A.I.

Probably the two most famous books about A.I. are I, Robot, released in 1950 by Isaac Asimov and 2001: A Space Odyssy, released in 1968 by Arthur C. Clarke.

I, Robot introduced the three laws of robotics. 1) A robot must not injure a human being, 2) a robot must obay the orders, except where the orders would conflict with the First Law and 3) a robot must protect its own existance as long as such protection does not conflict with the First or Second Laws.

2001: A Space Odyssey is a story about a psychopathic A.I. called HAL 9000 that intentionally tries to kill the humans on board a space station to save it’s own skin, in a sense.

But the history of AI stems back much further…

The Meaning of (Artificial) Life: A Prelude to What is Data Science?

Published

Slides Abstract The Hitchhiker’s Guide says the meaning of life is 42. Considering that the field of Data Science is going through a period of exponential growth it too could soon find that the meaning of an artificial life is also 42. But if you are not involved on a day-to-day basis, the expansion can seem bewildering. The story of how disparate disciplines have combined to produce Data Science is fascinating.

What Is Data Science?

Data Science is an emerging field that is plagued by lurid, often inconsequential reports of success. The press has been all too happy to predict the future demise of the human race.

But sifting through chaff, we do see some genuinely interesting reports of work that affects both bottom-line profit and top-line revenue.
