In this video, Billy Decker of StatSlice Systems shows you how to create and read a Classification Matrix in 5 minutes with the Microsoft Excel data mining add-in*. In this example, we will create a Classification Matrix based on a mining structure with all of its associated models that we have created previously. For the example, we will be using a tutorial spreadsheet that can be found on Codeplex at: https://dataminingaddins.codeplex.com/releases/view/87029 You will also need to attach the AdventureworksDW2012 data file to SQL Server which can be downloaded here: http://msftdbprodsamples.codeplex.com/releases/view/55330 *This tutorial assumes that you have already installed the data mining add-in for Excel and configured the add-in to be pointed at an instance of SQL Server with Analysis Services to which you have access rights.

In this episode, you can see our chief-data-science-executive-wizard-commander Ingo and Data Scientist #7 ride around in a shopping cart. Of course, they also have to do something else as they eventually get tired of it. So, Ingo uses M&Ms to explain ensemble methods and how you can leverage the combined expertise of a panel of machine learning algorithms to deliver better predictive power. Watch Ingo ‘crowd guess’ the number of M&Ms in a bowl by random sampling strangers in a parking lot and averaging the estimates - exemplifying the bagging method. Also, learn how the boosting method differs from bagging (obviously using more M&Ms). Data Scientist #7 loves not only the M&Ms but also the idea of ensembles so he immediately wants to boost his knowledge by checking out the book: “Wisdom of Crowds” by James Surowiecki which Ingo recommended reading.

Please Subscribe our goal is 5000 subscriber for this year :) Theoretical results in machine learning mainly deal with a type of inductive learning called supervised learning. In supervised learning, an algorithm is given samples that are labeled in some useful way. For example, the samples might be descriptions of mushrooms, and the labels could be whether or not the mushrooms are edible. The algorithm takes these previously labeled samples and uses them to induce a classifier. This classifier is a function that assigns labels to samples including the samples that have never been previously seen by the algorithm Source:http://en.wikipedia.org/wiki/Computational_learning_theory

Smartphone based automatic abnormality detection of kidney in ultrasound images Abstract: Telesonography suffers from inherent limitations due to the need of all time availability of experts in cloud and data connectivity to the device. Computer-aided diagnosis (CAD) used for automatic detection of abnormalities without manual intervention can overcome these limitations. Commercially available ultrasound scanners restrict the installation of new softwares and hence CAD algorithms cannot be integrated into the existing ultrasound scanners. There is a need for an external computing device, which can acquire image data from ultrasound scanners, perform CAD and generate result. Smart-phones are now widely used in personalized healthcare due to its ubiquitous computing capability. Smartphones with embedded CAD can be used as a computing device for automated diagnosis. In this paper, we have developed an Application (APP) for a smartphone to automatically diagnose the kidney in the ultrasound image. With the developed APP, the smartphone can acquire images from any ultrasound scanner, process it and give the diagnostic result. Automatic abnormality detection of kidney is based on Viola Jones algorithm, texture feature extraction followed by SVM classifier. Stones and cysts are the abnormalities detected using the algorithm. The developed APP resulted with an accuracy of 90.91% in detecting the abnormalities.

Machine Learning for Encrypted Malware Traffic Classification: Accounting for Noisy Labels and Non-Stationarity Blake Anderson (Cisco Systems, Inc.) David McGrew (Cisco Systems, Inc.) The application of machine learning for the detection of malicious network traffic has been well researched over the past several decades; it is particularly appealing when the traffic is encrypted because traditional pattern-matching approaches cannot be used. Unfortunately, the promise of machine learning has been slow to materialize in the network security domain. In this paper, we highlight two primary reasons why this is the case: inaccurate ground truth and a highly non-stationary data distribution. To demonstrate and understand the effect that these pitfalls have on popular machine learning algorithms, we design and carry out experiments that show how six common algorithms perform when confronted with real network data. With our experimental results, we identify the situations in which certain classes of algorithms underperform on the task of encrypted malware traffic classification. We offer concrete recommendations for practitioners given the real-world constraints outlined. From an algorithmic perspective, we find that the random forest ensemble method outperformed competing methods. More importantly, feature engineering was decisive; we found that iterating on the initial feature set, and including features suggested by domain experts, had a much greater impact on the performance of the classification system. For example, linear regression using the more expressive feature set easily outperformed the random forest method using a standard network traffic representation on all criteria considered. Our analysis is based on millions of TLS encrypted sessions collected over 12 months from a commercial malware sandbox and two geographically distinct, large enterprise networks.

Title: Dark Knowledge Abstract: A simple way to improve classification performance is to average the predictions of a large ensemble of different classifiers. This is great for winning competitions but requires too much computation at test time for practical applications such as speech recognition. In a widely ignored paper in 2006, Caruana and his collaborators showed that the knowledge in the ensemble could be transferred to a single, efficient model by training the single model to mimic the log probabilities of the ensemble average. This technique works because most of the knowledge in the learned ensemble is in the relative probabilities of extremely improbable wrong answers. For example, the ensemble may give a BMW a probability of one in a billion of being a garbage truck but this is still far greater (in the log domain) than its probability of being a carrot. This "dark knowledge", which is practically invisible in the class probabilities, defines a similarity metric over the classes that makes it much easier to learn a good classifier. I will describe a new variation of this technique called "distillation" and will show some surprising examples in which good classifiers over all of the classes can be learned from data in which some of the classes are entirely absent, provided the targets come from an ensemble that has been trained on all of the classes. I will also show how this technique can be used to improve a state-of-the-art acoustic model and will discuss its application to learning large sets of specialist models without overfitting.

Good features are informative, independent, and simple. In this episode, we'll introduce these concepts by using a histogram to visualize a feature from a toy dataset. Updates: many thanks for the supportive feedback! I’d love to release these episodes faster, but I’m writing them as we go. That way, I can see what works and (more importantly) where I can improve. We've covered a lot of ground already, so next episode I'll review and reinforce concepts, introduce clearer syntax, spend more time on testing, and continue building intuition for supervised learning. I also realize some folks had dependency bugs with Graphviz (my fault!). Moving forward, I won't use any libraries not already installed by Anaconda or Tensorflow. Last: my code in this cast is similar to these great examples.

Filmed at PyData London 2017 Description Mechanical ventilators are widely used in intensive care, they are sophisticated but Doctors do not have time to analyse the copious traces of data in a neonatal unit. We are providing an easy-to-interpret summary of this time-series data using visualisation and machine learning. This is an open source collaboration with the NHS, All results are open. Abstract Mechanical ventilators are widely used in intensive care. Even two decades ago they were be primarily mechanical devices whose "only" task was to inflate the patient’s lung. Recently, however, they have become equipped with powerful computers that provide sophisticated ventilator modes. Data provided by the ventilators are almost never downloaded, stored or analysed. The data is complex, high frequency and requires time-intensive scrutiny to review. Doctors do not have time to analyse these traces in a neonatal unit. We are providing a simple and easy-to-interpret summary of 100Hz dual-channel ventilator data to improve the quality of care of young infants by time-poor staff. This involves signal processing, visualisation, building a gold standard and machine learning to segment breaths and summarise a baby's behaviour. This builds on our talk at PyDataLondon Meetup 30 in January 2017. Our goal is to open source the research so that others can benefit from the processes that we develop. We invite feedback from the audience to help improve our methods. Anyone interested in time series data, automated labeling, scikit-learn, Bokeh and medical applications will find this talk of interest. Both the highs and lows of our current approaches will be discussed. This is a collaboration between Dr Gusztav Belteki (Cambridge University Hopsitals NHS Foundation Turst), Ian Ozsvald (ModelInsight) and Giles Weaver (ModelInsight). www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States.

The objective of this course is to give you a holistic understanding of machine learning, covering theory, application, and inner workings of supervised, unsupervised, and deep learning algorithms. In this series, we'll be covering linear regression, K Nearest Neighbors, Support Vector Machines (SVM), flat clustering, hierarchical clustering, and neural networks. For each major algorithm that we cover, we will discuss the high level intuitions of the algorithms and how they are logically meant to work. Next, we'll apply the algorithms in code using real world data sets along with a module, such as with Scikit-Learn. Finally, we'll be diving into the inner workings of each of the algorithms by recreating them in code, from scratch, ourselves, including all of the math involved. This should give you a complete understanding of exactly how the algorithms work, how they can be tweaked, what advantages are, and what their disadvantages are. In order to follow along with the series, I suggest you have at the very least a basic understanding of Python. If you do not, I suggest you at least follow the Python 3 Basics tutorial until the module installation with pip tutorial. If you have a basic understanding of Python, and the willingness to learn/ask questions, you will be able to follow along here with no issues. Most of the machine learning algorithms are actually quite simple, since they need to be in order to scale to large datasets. Math involved is typically linear algebra, but I will do my best to still explain all of the math. If you are confused/lost/curious about anything, ask in the comments section on YouTube, the community here, or by emailing me. You will also need Scikit-Learn and Pandas installed, along with others that we'll grab along the way. Machine learning was defined in 1959 by Arthur Samuel as the "field of study that gives computers the ability to learn without being explicitly programmed." This means imbuing knowledge to machines without hard-coding it. https://pythonprogramming.net/machine-learning-tutorial-python-introduction/ https://twitter.com/sentdex https://www.facebook.com/pythonprogra... https://plus.google.com/+sentdex

With a growing interest in interpretability, there is an increasing need to characterize what exactly we mean by it and how to sensibly compare the interpretability of different approaches. In this talk, I'll start by discussing some research in interpretable machine learning from our group, and then broaden it out to discuss what interpretability is and when it is needed. I'll argue that our current desire for "interpretability" is as vague as asking for "good predictions" -- a desire that. while entirely reasonable, must be formalized into concrete needs such as high average test performance (perhaps held-out likelihood is a good metric) or some kind of robust performance (perhaps sensitivity or specificity are more appropriate metrics). This objective of this talk is to start a conversation to do the same for interpretability: I will suggest a taxonomy for interpretable models and their evaluation, and also highlight important open questions about the science of interpretability in machine learning.
