1. Great resources for learning data mining concepts and techniques:

With today’s tools, anyone can collect data from almost anywhere, but not everyone can pull the important nuggets out of that data. Whacking your data into Tableau is an OK start, but it’s not going to give you the business critical insights you’re looking for. To truly make your data come alive you need to mine it. Dig deep. Play around. And tease out the diamond in the rough.

About TensorFlow:

TensorFlow™ is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google’s Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well.

2 . Introduction of Markov State Modeling:

Modeling and prediction problems occur in different domain and data situations. One type of situation involves sequence of events.

For instance, you may want to model behaviour of customers on your website, looking at pages they land or enter by, links they click, and so on. You may want to do this to understand common issues and needs and may redesign your website to address that. You may, on the other hand, may want to promote certain sections or products on website and want to understand right page architecture and layout. In other example, you may be interested in predicting next medical visit of patient based on previous visits or next purchase product of customer based on previous products.

5. Facebook data collection and photo network visualization with Gephi and R:

The first thing to do is get the Facebook data. Before being allowed to pull it from R, you’ll need to make a quick detour to developers.facebook.com/apps, register as a developer, and create a new app. Name and description are irrelevant, the only thing you need to do is go to Settings → Website → Site URL and fill in http://localhost:1410/ (that’s the port we’re going to be using). The whole process takes ~5 min and is quite painless

7. Rapid Development & Performance in Spark For Data Scientists:

Spark is a cluster computing framework that can significantly increase the efficiency and capabilities of a data scientist’s workflow when dealing with distributed data. However, deciding which of its many modules, features and options are appropriate for a given problem can be cumbersome. Our experience at Stitch Fix has shown that these decisions can have a large impact on development time and performance. This post will discuss strategies at each stage of the data processing workflow which data scientists new to Spark should consider employing for high productivity development on big data.

8. NoSQL: A Dog with Different Fleas:

The NoSQL movement is around providing performance, scale, and flexibility; where cost is sometimes part of the reasoning (e.g. Oracle Tax). Yet databases like MySQL, which provide all the Oracle features, is often considered before choosing NoSQL. And with respects to NoSQL flexibility. This also can be Pandora’s box. In other words, schema-less modeling has been shown to be a serious complication to data management. I was at the MongoDB Storage Engine Summit this year and the number one ask to the storage engine providers is “how to discover schema in a schema-less architecture?” In other words, managing models over time is a serious matter to consider too.

9. Apache Spark: Sparkling star in big data firmament:

The underlying data needed to be used to gain right outcomes for all above tasks is comparatively very large. It cannot be handled efficiently (in terms of both space and time) by traditional systems. These are all big data scenarios. To collect, store and do computations on this kind of voluminous data we need a specialized cluster computing system. Apache Hadoop has solved this problem for us.

10. Sqoop vs. Flume – Battle of the Hadoop ETL tools:

Apache Hadoop is synonymous with big data for its cost-effectiveness and its attribute of scalability for processing petabytes of data. Data analysis using hadoop is just half the battle won. Getting data into the Hadoop cluster plays a critical role in any big data deployment. Data ingestion is important in any big data project because the volume of data is generally in petabytes or exabytes. Hadoop Sqoop and Hadoop Flume are the two tools in Hadoop which is used to gather data from different sources and load them into HDFS. Sqoop in Hadoop is mostly used to extract structured data from databases like Teradata, Oracle, etc., and Flume in Hadoop is used to sources data which is stored in various sources like and deals mostly with unstructured data.
