To spot such trends, you don't have to look far beyond the reach of Alibaba.Besides their obvious success on B2C (Tmall.com) as well as C2C(Tabao.com), they have made tremendous progress or bold attempts on these areas.1. Go mobileThey have mobile apps for Tmall, Taobao and most noticeably Alipay, which is the payment tool of choice on Android platform in China, and the major tool to buy non-virtual goods on iOS (No you can't buy real-life goods through App Store or In App Purchase)2. Connecting the dataNo one owns more lucrative data in China like Alibaba, and boasts better data analytical technology. Not only can they tell which city in China is most cat friendly, or coupon addict, or home to girls with largest bra size by mining their own data, but also they become able to do cross reference with other major Chinese sites.The recent example is only a few days after Alibaba acquired 18% of Sina Weibo, weibo users start to find in their message boards are promotions from Taobao, many relevant to their recent purchasing histories.Imagine Amazon being able to access your facebook or twitter data, you will get the picture.3. Infiltration to many aspects of lifeIn addition to the many things people could already do previously with Taobao, like paying rents, utilities and traffic tickets, they can now register for appointments in several hundred hospitals across a score of provinces.At the same time Alibaba has been making agressive acquisitions of other internet companies in China. Besides Sina Weibo aforementioned, they acquired Autonavi(the major map service provider in China) and xiami.com(one online music streaming and sharing platform).4. Providing banking-live serviceBoth Alibaba's B2B and B2C services are starting giving loans(up to 1 million CNY) to the sellers, mortgage free, based on their reputation and money receivables.5. Building infrastructureTheir lesser known business Aliyun started to provide cloud service since 2009, but I'm yet to see they grow out of the current infancy. Having been using their services for more than a year, I would say what they can offer up till now are not as sophisticated as we used to get from Linode, not to mention to compare with Amazon's S3 and EC2.

A while ago, I wrote about some free resources you can use to learn data science on your own. This was mainly geared towards folks who wanted to apply to The Data Incubator's free Data Science Fellowship as a useful "getting started" guide but it's a useful place to start regardless of where you want to apply to be a data scientist. I'll break up my answer into two parts:Free resources broken down by topic: While you are coming at this with an expertise in machine-learning, there are a number of other useful aspects of data science to learn. The response is more general interest.Free Data sources with which you can gain hands-on experience. One of the linchpins of our data science fellowship is the building of a capstone project that you use to showcase your newfound data science knowledge.#1: New Topics to Learn [original post]Here are five important skills to develop and some resources on how to help you develop them. While we don't expect our applicants to possess all of these skills, most applicants already have a strong background in many of them.Scraping: There's a lot of data out there so you'll need to learn how to get access to it. Whether it's JSON, HTML or some homebrew format, you should be able to handle them with ease. Modern scripting languages like Python are ideal for this. In Python, look at packages like urllib2, requests, simplejson, re, and beautiful soup to make handling web requests and data formats easier. More advanced topics include error handling (retrying) and parallelization (multiprocessing).SQL: Once you have a large amount of structured data, you will want to store and process it. SQL is the original query language and its syntax is so prevalent that there are SQL query interfaces for everything from sqldf for R data frames to Hive for Mapreduce.Normally, you would have to go through a painful install process to play with SQL. Fortunately, there's a nice online interactive tutorialavailable where you can submit your queries and learn interactively. Additionally, Mode Analytics has agreat tutorial geared towards data scientists, although it is not interactive. When you're ready to use SQL locally, SQLite offers a simple-to-install version of SQL.Data frames: SQL is great for handling large amounts of data but unfortunately it lacks machine learning and visualization. So the workflow is often to use SQL or mapreduce to get data to a manageable size and then process it using a libraries like R's data frames or Python's pandas. For Pandas, Wes McKinney, who created pandas, has a great video tutorial on youtube. Watch it here and follow along by checking out the github code.Machine-Learning: A lot of data science can be done with select, join, and groupby (or equivalently, map and reduce) but sometimes you need to do some non-trivial machine-learning. Before you jump into fancier algorithms, try out simpler algorithms like Naive Bayes andregularized linear regression. In Python, these are implemented in scikit learn. In R, they are implemented in the glm and gbmlibraries. You should make sure you understand the basics really well before trying out fancier algorithms.Visualization: Data science is about communicating your findings, and data visualization is an incredibly valuable part of that. Python offers Matlab-like plotting via matplotlib, which is functional, even if its ascetically lacking. R offers ggplot, which is prettier. Of course, if you're really serious about dynamic visualizations, tryd3.These are some of the foundational skills that will be invaluable to your career as a data scientist. While they only cover a subset of what we talk about at The Data Incubator (there's a lot more to cover in stats, machine-learning, and mapreduce), this is a great start.

Our hiring partners love considering Fellows who don’t mind getting their hands dirty with data. That’s why our Fellows work on cool capstone projects that showcase those skills. One of the biggest obstacles to successful projects has been getting access to interesting data.
