Competition in customer experience management has never been as challenging as it is now. Customers spend more money in aggregate, but less per brand. The average size of a single purchase has decreased, partly because competitive offers are just one click away. Predicting offer relevance to potential (and existing) customers plays a key role in segmentation strategies, increasing macro- and micro-conversion rates, and the average order size. This session (and the associated white paper) covers the following topics: factorization machines and how they support personalized marketing; how SAS® Visual Data Mining and Machine Learning with SAS® Customer Intelligence 360 support building and deploying factorization machines with digital experiences; and a step-by-step demonstration and business use case for the sas.com bookstore.

Naive Bayes Classifier- Fun and Easy Machine Learning ►FREE YOLO GIFT - http://augmentedstartups.info/yolofreegiftsp ►KERAS COURSE - https://www.udemy.com/machine-learning-fun-and-easy-using-python-and-keras/?couponCode=YOUTUBE_ML ►MACHINE LEARNING COURSES - http://augmentedstartups.info/machine-learning-courses -------------------------------------------------------------------------------- Now Naïve Bayes is based on Bayes Theorem also known as conditional Theorem, which you can think of it as an evidence theorem or trust theorem. So basically how much can you trust the evidence that is coming in, and it’s a formula that describes how much you should believe the evidence that you are being presented with. An example would be a dog barking in the middle of the night. If the dog always barks for no good reason, you would become desensitized to it and not go check if anything is wrong, this is known as false positives. However if the dog barks only whenever someone enters your premises, you’d be more likely to act on the alert and trust or rely on the evidence from the dog. So Bayes theorem is a mathematic formula for how much you should trust evidence. So lets take a look deeper at the formula, • We can start of with the Prior Probability which describes the degree to which we believe the model accurately describes reality based on all of our prior information, So how probable was our hypothesis before observing the evidence. • Here we have the likelihood which describes how well the model predicts the data. This is term over here is the normalizing constant, the constant that makes the posterior density integrate to one. Like we seen over here. • And finally the output that we want is the posterior probability which represents the degree to which we believe a given model accurately describes the situation given the available data and all of our prior information. So how probable is our hypothesis given the observed evidence. So with our example above. We can view the probability that we play golf given it is sunny = the probability that we play golf given a yes times the probability it being sunny divided by probability of a yes. This uses the golf example to explain Naive Bayes. ------------------------------------------------------------ Support us on Patreon ►AugmentedStartups.info/Patreon Chat to us on Discord ►AugmentedStartups.info/discord Interact with us on Facebook ►AugmentedStartups.info/Facebook Check my latest work on Instagram ►AugmentedStartups.info/instagram Learn Advanced Tutorials on Udemy ►AugmentedStartups.info/udemy ------------------------------------------------------------ To learn more on Artificial Intelligence, Augmented Reality IoT, Deep Learning FPGAs, Arduinos, PCB Design and Image Processing then check out http://augmentedstartups.info/home Please Like and Subscribe for more videos :)

By Wayne Oldford and Adrian Waddell University of Waterloo Visualisation of Complex Data Sets session at the ISI Dublin, Ireland. ISI 2011. Article: http://isi2011.congressplanner.eu/pdfs/650370.pdf Abstract: STS057.04 -- Visual Clustering of High-Dimensional Data by Navigating Low-Dimensional Spaces Wayne Oldford, Adrian Waddell Statistics and Actuarial Science, University of Waterloo, Waterloo, ON, Canada The structure of a set of high dimensional data objects (e.g. images, documents, molecules, genetic expressions, etc.) is notoriously difficult to visualize. In contrast, lower dimensional structure (esp. 3 or fewer dimensions) is natural to us and easy to visualize. A not unreasonable approach, then, is to explore one low dimensional visualization after another in the hope that, together, these will shed light on the higher dimensional structure. A familiar example is the parallel coordinate plot, where a sequence of one-dimensional projections are connected to provide insight into the structure of a high dimensional data set. In this talk, we describe the graph theoretic structure, recently proposed in Hurley and Oldford (2011, Comp. Stat.), that represents low-dimensional spaces as graph nodes and transitions between spaces as edges. Of interest, are walks along these graphs that reveal meaningful structure. If the nodes are one-dimensional, a walk corresponds to a parallel coordinate plot; if they are two dimensional and edges exist, say, only between 2d spaces which share a variate, then the walk could be represented dynamically as a series of scatterplots, one transitioning into the next via a 3d rigid transformation. We demonstrate how these graphs are constructed and dynamically explored via our R package, RnavGraph. These graphs, unfortunately, grow in size with the square of the number of dimensions. Fortunately, there are numerous means for constructing only the more interesting regions of each graph. Some restrictions are imposed by the statistical context, others by empirical measures on the data itself. Of the latter, scatterplot diagnostics (scagnostics) are especially valuable. When the objective is to visually cluster the data, nearest neighbour based dimension reduction methods are particularly effective in conjunction with appropriate scagnostics. We demonstrate these methods using RnavGraph. Keywords: Graph navigation, transition graphs; RnavGraph; High-dimensional data; Visual clustering Biography: Wayne Oldford is a Professor of Statistics and of Computer Science at the University of Waterloo, Canada. His research interests include data visualization, cluster analysis, quantitative programming environments, and statistical foundations. Prof. Oldford is a long-standing member of the International Statistical Institute, and even longer of the International Association for Statistical Computing.

You take a look at the data and quickly realize it's an absolute mess. According to IBM Data Analytics you can expect to spend up to 80% of your time on a project cleaning data. There's all different types of messy data, but today we're going to focus on one of the most common, missing values. We'll take a look at standard types that Pandas recognizes out of the box. Next we'll take a look at some non-standard types. These are inputs that Pandas won't automatically recognize as missing values. After that we'll take a look at unexpected types. Let's say you have a column of names that contains a 12, technically that's a missing value. After we've finished detecting missing values we'll learn how to summarize and do simple replacements.

The author's personal website: http://dongyu.tech More information please refer to the paper: http://dongyu.name/papers/tvcg_2016_dongyu_smartadp.pdf Online System: http://smartadp.chinacloudapp.cn/ Abstract: The problem of formulating solutions immediately and comparing them rapidly for billboard placements has plagued advertising planners for a long time, owing to the lack of efficient tools for in-depth analyses to make informed decisions. In this study, we attempt to employ visual analytics that combines the state-of-the-art mining and visualization techniques to tackle this problem using large-scale GPS trajectory data. In particular, we present SmartAdP, an interactive visual analytics system that deals with the two major challenges including finding good solutions in a huge solution space and comparing the solutions in a visual and intuitive manner. An interactive framework that integrates a novel visualization-driven data mining model enables advertising planners to effectively and efficiently formulate good candidate solutions. In addition, we propose a set of coupled visualizations: a solution view with metaphor-based glyphs to visualize the correlation between different solutions; a location view to display billboard locations in a compact manner; and a ranking view to present multi-typed rankings of the solutions. This system has been demonstrated using case studies with a real-world dataset and domain-expert interviews. Our approach can be adapted for other location selection problems such as selecting locations of retail stores or restaurants using trajectory data.

Smart Brushing for Parallel Coordinates by Richard C. Roberts, Robert S. Laramee, Gary A. Smith, Paul Brookes, Tony D’Cruze in IEEE Transactions on Visualization and Computer Graphics (IEEE TVCG), forthcoming Abstract: The Parallel Coordinates plot is a popular tool for the visualization of high-dimensional data. One of the main challenges when using parallel coordinates is occlusion and overplotting resulting from large data sets. Brushing is a popular approach to address these challenges. Since its conception, limited improvements have been made to brushing both in the form of visual design and functional interaction. We present a set of novel, smart brushing techniques that enhance the standard interactive brushing of a parallel coordinates plot. We introduce two new interaction concepts: Higher-order, sketch-based brushing, and smart, data-driven brushing. Higher-order brushes support interactive, flexible, n-dimensional pattern searches involving an arbitrary number of dimensions. Smart, data-driven brushing provides interactive, real-time guidance to the user during the brushing process based on derived meta-data. In addition, we implement a selection of novel enhancements and user options that complement the two techniques as well as enhance the exploration and analytical ability of the user. We demonstrate the utility and evaluate the results using a case study with a large, high-dimensional, real-world telecommunication data set and we report domain expert feedback from the data suppliers.

Google Tech Talk June 24, 2013 (more info below) Presented by Laurens van der Maaten, Delft University of Technology, The Netherlands ABSTRACT Visualization techniques are essential tools for every data scientist. Unfortunately, the majority of visualization techniques can only be used to inspect a limited number of variables of interest simultaneously. As a result, these techniques are not suitable for big data that is very high-dimensional. An effective way to visualize high-dimensional data is to represent each data object by a two-dimensional point in such a way that similar objects are represented by nearby points, and that dissimilar objects are represented by distant points. The resulting two-dimensional points can be visualized in a scatter plot. This leads to a map of the data that reveals the underlying structure of the objects, such as the presence of clusters. We present a new technique to embed high-dimensional objects in a two-dimensional map, called t-Distributed Stochastic Neighbor Embedding (t-SNE), that produces substantially better results than alternative techniques. We demonstrate the value of t-SNE in domains such as computer vision and bioinformatics. In addition, we show how to scale up t-SNE to big data sets with millions of objects, and we present an approach to visualize objects of which the similarities are non-metric (such as semantic similarities). This talk describes joint work with Geoffrey Hinton.

About the webinar Part 1: Discovery Dashboard Drs. Chau and Sharmin will present Discovery Dashboard , a visual analytics system for exploring large volumes of time series data from mobile medical field studies, in the web-browser and in real time. Discovery Dashboard offers interactive exploration tools and a data mining motif discovery algorithm to help researchers formulate hypotheses, discover trends and patterns, and ultimately gain a deeper understanding of their data. They will demonstrate their system visualizing data from a mobile sensor study conducted at the University of Minnesota that included 52 participants who were trying to quit smoking. Part 2: MyQuitPal The first step in designing effective smoking cessation systems is to objectively identify factors that contribute to lapse. To this end, we present MyQuitPal , a participant-centric cessation support system, which aims to assist individuals to better understand their smoking behavior. MyQuitPal combines an affective mobile application  and a web-based analytics tool  to support reflection. The design of MyQuitPal is informed by in-depth analysis of physiological data collected utilizing wearable sensors from a four day pre-quit, post-quit study (N=55). Visualizations presented in MyQuitPal are also grounded on theories of long term health-behavior change.

Speaker: Chris "The Suggmeister" Sumner If you're ever in a position when you need to pwn criminals via social networks or see where Tony Hawk likes to hide skateboards around the world, this talk is for you. The talk is delivered in two parts, both of which are intended to shine a fun light on visual social network analysis. The first part introduces how you can extend the powerful data visualization tool, Maltego to speed up and automate the data mining and analysis of social networks. I'll show how I analyzed skateboard legend, Tony Hawk's twitter hunt and highlight how you could use the same techniques to set up your very own backyard miniature ECHELON. The second part illustrates how these techniques have been used to enumerate a 419 scam, infiltrate the scammers social network and expose deeper, more sinister links to organized crime. I focus specifically on Twitter and Facebook, demonstrating how you can graphically map and analyze social relationships using the Twitter API's, publicly available Facebook profiles, screen scraping and some clunky regex." Related to this talk is the DEF CON Twitter Hunt Each day at DEF CON you will have an opportunity to blag yourself a sweet limited edition DEF CON-ized skateboard deck. There may also be a couple of signed Tony Hawk decks slung in for good measure too... who knows. You will have to follow @TheSuggmeister during DEF CON to know where to look. He'll be tweeting clues which lead to prizes.

In this Python Tutorial, we will be learning how to install, setup, and use Jupyter Notebooks. Jupyter Notebooks have become very popular in the last few years, and for good reason. They allow you to create and share documents that contain live code, equations, visualizations and markdown text. This can all be run from directly in the browser. It is an essential tool to learn if you are getting started in Data Science, but will also have tons of benefits outside of that field.

Rick Walker, Phillip A. Legg, Serban Pop, Zhao Geng, Robert S. Laramee, and Jonathan C. Roberts, Force-Directed Parallel Coordinates, Proceedings of the Conference on Information Visualization (IV) 2013, 15-18 July, University of London, London, UK Abstract: Parallel coordinates are a well-known and valuable technique for the analysis and visualization of high dimensional data sets. However, while Inselberg emphasizes that the strength of parallel coordinates as a methodology is rooted in exploration and interactivity, the set of interaction techniques is currently limited. Axes can be re-ordered and brushing (simple, angular or multi-dimensional) can be performed. In this paper, we propose a force-directed algorithm and related interaction techniques to support the exploration of parallel coordinate plots through a physical metaphor. Our parallel-coordinates visualization offers novel user interaction beyond the standard techniques by allowing the user to rotate the axis according to forcedirected polylines. The new interaction provides the user with a more immersive experience for data exploration that results in greater intuition of the data, especially in cases where many polylines overlap. We demonstrate our approach, then present the results of a qualitative evaluation of the system.

Extracting useful patterns from large network datasets has become a fundamental challenge in many domains. We present VISAGE, an interactive visual graph querying approach that empowers users to construct expressive queries, without writing complex code (e.g.,finding money laundering rings of bankers and business owners).Our contributions are as follows: (1) we introduce graph-autocomplete, an interactive approach that guides users to construct and refine queries, preventing over-specification; (2) VISAGE guides the construction of graph queries using a data-driven approach, enabling users to specify queries with varying levels of specificity, from concrete and detailed (e.g., query by example), to abstract (e.g., with “wildcard” nodes of any types), to purely structural matching; (3)a twelve-participant, within-subject user study demonstrates VISAGE’s ease of use and the ability to construct graph queries significantly faster than using a conventional query language; (4) VISAGE works on real graphs with over 468K edges, achieving sub-second response times for common queries Robert's homepage: http://www.cc.gatech.edu/~rpienta3/ Paper: http://www.cc.gatech.edu/~dchau/papers/16-avi-visage.pdf VISAGE: Interactive Visual Graph Querying.

Chao Tong, Richard Roberts, Robert S Laramee, Daniel Thayer, Damon Berridge, Cartographic Treemaps for the Visualization of Public Healthcare Data, The Computer Graphics and Visual Computing (CGVC) Conference 2017, forthcoming, 14-15 September 2017, Manchester, UK PDF http://cs.swan.ac.uk/~csbob/research/cartographic/tong17cartographic.pdf Abstract: The National healthcare Service (NHS) in the UK collects a massive amount of high-dimensional, region-centric data concerning individual healthcare units throughout Great Britain. It is challenging to visually couple the large number of multivariate attributes about each region unit together with the geo-spatial location of the clinical practices for visual exploration, analysis, and comparison. We present a novel multivariate visualization we call a cartographic treemap that attempts to combine the space-filling advantages of treemaps for the display of hierarchical, multivariate data together with the relative geo-spatial location of NHS practices in the form of a modified cartogram. It offers both space filling and geospatial error metrics that provide the user with interactive control over the space-filling versus geographic error trade-off. The result is a visualization that offers users a more space efficient overview of the complex, multivariate healthcare data coupled with the relative geo-spatial location of each practice to enable and facilitate exploration, analysis, and comparison. We evaluate the two metrics and demonstrate the use of our approach on real, large high-dimensional NHS data and derive a number of multivariate observations based on healthcare in the UK as a result. We report the reaction of our software from two domain experts in health science.

Here the idea for solving the multiple criteria decision making problems is to visually and effectively model the problem and clarify the whole dimension of it. We use Grapheur, the flexible and power full business intelligence and interactive visualization. We are dealing with the series of multiple criteria decision making problems related to construction workers of Canadian construction projects. For instance we want to figure out with which rate and how, should the workers' level of skills grow in order to maintain their performances with regard to team perceptions of supervision. In the figure, a 3D plot of the network is given by the 23 workers. The color code represents the specialization of the workers and the size of the bubbles is proportional to the idleness of each worker. As you see for a part of our project we are considering the 3D similarity map and on the left side of the screen, the parallel filters, optimizing the idleness characteristic of the workers with respect to our mentioned objectives. In our 3D similarity map of graphical visualization, the gray level of the edges and the generated clusters provide the valuable information for decision makers. The capability of the Similarity Map in clustering the workers into different clusters is illustrated. Parallel filters are other useful tools for optimization. The usefulness of parallel filters in reducing the complexity of decision making is evaluated. References: 1Hewage K.N., Gannoruwa A., Ruwanpura J.Y.
