50 Excellent Data Visualization Examples for Presentations
Data presentation should be elegant, detailed and beautiful. There are different ways to show the data that can be a pie charts, tables, histograms, and bar graph. However, to send a clear and effective message to your readers, you just need more than just a simple table or histogram, etc. There are some data visualization techniques that present your data much better than expected, intelligent, beautiful, original and in an excellent way. We have gathered some of the most attractive and unique ideas of data visualization examples.

Gold Mine or Blind Alley? Functional Programming for Big Data & Machine Learning
Functional programming is touted as a solution for big data problems. Why is it advantageous? Why might it not be? And who is using it now?

Model Management and Deployment
Have you experienced or thought how corporates manage their analytical assets which are mission critical to the business? A Bank or a Telecom Service Provider may often have more than 100 predictive model assets developed over a time period, but faces an important issue of how to effectively manage,store,share or archive these assets.

The Science of Crawl (Part 3): Prioritization
This is Part 3 in our series ‘The Science of Crawl’ addressing the technical challenges around growing and maintaining a web corpus. In Part 1, we introduced a funnel for deduplicating web documents within a search index. The dual problems of exact-duplicate and near-duplicate web document identification are considered. By chaining together several methods with increasing specificity we identify a system that provides sufficient precision and recall with minimal computational trade-offs. In Part 2 we visit the problem of balancing resource allocation between crawling new pages and revisiting stale ones.

Regression – covariate adjustment
Linear regression is one of the key concepts in statistics [wikipedia1, wikipedia2]. However, people are often confuse the meaning of parameters of linear regression – the intercept tells us the average value of y at x=0, while the slope tells us how much change of y can we expect on average when we change x for one unit – exactly the same as in the linear function, though we use averages here due to noise.

Useful R snippets
In this post we collect several R one- or few-liners that we consider useful. As our minds tend to forget these little fragments we jot them down here so we will find them again.

Crawling facebook with R
So, let’s crawl some data out of facebook using R. Don’t get too excited though, this is just a weekend whatif project. Anyway, so for example, I want to download some photos where I’m tagged.

Time series cross-validation: an R example
I was recently asked how to imple­ment time series cross-​​validation in R. Time series peo­ple would nor­mally call this ‘fore­cast eval­u­a­tion with a rolling ori­gin’ or some­thing sim­i­lar, but it is the nat­ural and obvi­ous ana­logue to leave-​​one-​​out cross-​​validation for cross-​​sectional data, so I pre­fer to call it ‘time series cross-​​validation’.

Cohort Analysis and LifeCycle Grids mixed segmentation with R
This is the third post about LifeCycle Grids. You can find the first post about the sense of LifeCycle Grids and A-Z process for creating and visualizing with R programming language here. Lastly, here is the second post about adding monetary metrics (customer lifetime value – CLV – and customer acquisition cost – CAC) to the LifeCycle Grids.

Modeling Count Time Series with tscount Package
The example below shows how to estimate a simple univariate Poisson time series model with the tscount package. While the model estimation is straightforward and yeilds very similar parameter estimates to the ones generated with the acp package (https://statcompute.wordpress.com/2015/03/29/autoregressive-conditional-poisson-model-i), the prediction mechanism is a bit tricky.
