How Colleges Could Get Rid of Fraternities
Finding nooks of growth in a sluggish Europe
Beneath this lackluster scenario, though, lie several layers of companies that are part of Europe's turnaround story. Here are two options you might consider: The FirstTrust Europe AlphaDEX exchange-traded fund, invests in an equal-weighted portfolio of European stocks, some of which aren't the name-brand companies found in most capitalization-weighted portfolios. By avoiding concentration in many of the mega-caps dominating most European portfolios, the AlphaDEX has sampled several smaller companies poised for growth, especially those in weaker but recovering euro zone economies such as Greece, Ireland and Spain. For a more focused approach on small-company stocks, consider the WisdomTree Europe SmallCap Dividend Fund.

After Building A Powerful Recommendation System For Netflix, This Guy Wants To Help You Find Your Next Favorite Book
Nicholas Ampazis builds software that makes recommendations for you. Where it was once making movie recommendations on Netflix, he's turning it to the book world.
It started in 2006 when Ampazis and a small team competed for the Netflix Prize, a competition that the company sponsored to pit engineers against each other to see who can build the best movie recommendation engine. When the competition ended in 2009, Ampazis and his team had won second place. He's now plying his skills in computer-enhanced recommendations for Entitle, a company that aims to be the Amazon of just e-books.
And with the number of books Entitle customers sift through in search of their next great read, why not use a computer to help you eliminate irrelevant stuff you don't like?
We caught up with Ampazis via email to learn more.
BUSINESS INSIDER: What's your background?
NICHOLAS AMPAZIS: I studied electrical engineering at Imperial College London and after my graduation I continued my studies pursuing a master's and a PhD degree in neural networks from King's College London and National Technical University of Athens, respectively. I'm currently an assistant professor at University of the Aegean, Greece, and I'm leading the Data Science group at Pattern Explorations Ltd, London.
BI: What is your relationship to the Netflix recommendation engine? How long were you involved?
NA: My team got involved with the Netflix Prize since its launch in late 2006. We called our team "Feeds2" — named after the Feeds 2.0 personalized news aggregator service that we'd launched earlier that year. What was special about that competition is that it put the spotlight on the use of data mining and machine learning methods for predicting user preferences. The Netflix Prize provided an excellent opportunity, as well as a challenge, for us in order to test the efficiency and scaling of the algorithms developed for the Feeds 2.0 service. Initially we tried to implement some of our Feeds 2.0 algorithms for the Netflix dataset, but it soon became apparent that the problem was quite different.
Feeds 2.0 used a lot of text mining methods that were found to be inapplicable to the Netflix dataset due to the different nature of the data involved. In the Netflix Prize there was no textual information and the only applicable algorithms that we'd had from Feeds 2.0 were pretty much along the same lines of the Cinematch approach that Netflix already had. It took a lot of effort developing collaborative filtering/machine learning methods and code from scratch in order to climb up quickly on the Netflix prize leaderboard. In July 2009, when the competition ended, we ended up in the 2nd place as members of "The Ensemble" team (tied in score with the winning team). Feeds2 was also the 3rd autonomous team in the leaderboard.
BI: What kinds of things did the Netflix software look at to make recommendations? How long you watched something?
NA: The dataset released for the Netflix Prize consisted of star ratings (on a scale 1-5) that users gave to movies that they'd already watched. At the time the prize was announced Netflix was a DVD company and the goal was to help people fill their queue with titles to receive in the mail over the coming days and weeks (therefore there was no feedback during viewing). However, Netflix as a whole has changed dramatically in the last few years.
Netflix launched an instant streaming service in 2007, one year after the Netflix Prize began. Streaming has not only changed the way members interact with the service, but also the type of data available to use in the algorithms. For streaming, members are looking for something great to watch right now; they can sample a few videos before settling on one, they can consume several in one session, and therefore Netflix can observe viewing statistics such as whether a video was watched fully or only partially. So nowadays, Netflix monitors a plethora of signals that they blend into their recommendation engine.
BI: What are the differences between recommending books and movies?
NA: Entitle is a paradise for recommendations because we have two very well-defined sources of information. The actual text that is contained in the books, plus the star ratings that users give to the books that they read. Thus we have the best of both worlds. We can apply the text mining methods that we'd developed for Feeds 2.0 (enhanced with the latest findings in text mining research) and the collaborative filtering / machine learning methods from the Netflix prize.
A very important parameter here is the psychological process by which users rate a book. This is a very well thought process because reading a book takes significantly more time than watching a movie. Therefore people select carefully the star rating to give to a book they've read depending on the emotions that it made them feel while they were reading it. This makes the rating signals that we have at our disposal quite more accurate than those that we had for the Netflix prize.
BI: How does one build a book recommendation engine?
NA: A good recommendation engine is judged by the quality of the recommendations that it produces and by its utility to users. There is a variety of factors and metrics that can measure the performance of the recommendation engine. Examples are the deviation of the engine's predictions from known ratings, the quality of similarities that it produces between books or between users with similar tastes, or the choice of the order by which to place the recommended books. Optimizing all these factors is critical in providing an effective personalized experience.
BI: What types of interactions does Entitle's system look for to make recommendations?
NA: Entitle's recommendation engine utilizes a suite of machine learning algorithms that aim to discover and annotate the archive of Entitle's book collection with topical information. It analyzes the actual texts to discover the topics that run through them and how those topics are connected to each other. It then utilizes the results of the analysis to assign the books to well defined multi-thematic areas.
Thus, in a sense, Entitle's recommendation engine is like having a librarian at your disposal who has actually read all the books in the library and knows which are the most representative books for each subject.
In addition, as is the case with a trusted librarian in your local library, the engine can monitor how your tastes for certain subjects change over time and can adjust its focus on providing trusted recommendations on the new topics of interest while not losing track of past associations.
BI: In general, how good are people at finding things they like, such as movies, books, otherwise? Do they do better with help from software such as this?
NA: American psychologist Barry Schwartz in his book "The Paradox of Choice: Why More Is Less" argued that people become less satisfied with their decision when they are given more options to choose from. Thus eliminating some irrelevant choices can greatly reduce consumer anxiety.
In addition as more and more rapidly changing information becomes available, people are overwhelmed by the new information and are no longer able to maintain trust on their decisions. The publishing, movie, and music industries are notable examples that provide practically endless choices. Recommendation systems as an integral part of any such online service can indeed help users by providing better access to the products that fit their needs and help them discover items that they would otherwise likely miss in a sea of information.
Over 35% of sales at Amazon and Netflix comes from recommendations, which, if anything, proves the indisputable value of a good recommendation system.

Ukrainian flagship defects while in a EU port
Ukraine’s Navy flagship, the Hetman Sahaidachny frigate, that has reportedly announced it will no longer follow orders from Kiev but will only serve the independent republic of Crimea, is in Greece, in the Naval station of Souda, in Crete, according to reports.
According to defencenet.gr, the frigate, that was expected to be in Sevastopol in early March, has been in Souda, Greece since 28 February, the day the independent movement of Crimea emerged. The frigate originaly planned to remain in Greece until next Wednesday but it is unknown what will now happen.
The Hetman Sahaidachny crew issued yesterday an announcement, saying that it will no longer take orders from Kiev but will only serve the independent republic of Crimea.
Senator Igor Morozov, a member of the committee on the international affairs of the Russian Duma, told Izvestia daily.: “Ukraine’s Navy flagship the Hetman Sahaidachny has come over to our side today. It has hung out the St Andrew’s flag.” However, this is reportedly false since the ship never raised the Russian flag.
Ukrainian media reports indicated that Prime Minister of Ukraine Arseniy Yatsenyuk asked the Greek government to forbid the departure of the vessel and the Turkish government not to allow the frigate to pass through the Strait of Bosporus.
According to defencenet.gr, Russia said no one can forbid the frigate to leave the naval station of Souda and warned that if Greece tries to do so, the reduction in the price of natural gas agreed between the two countries would be at stake.
On the other hand, the Chief of the Armed Forces of Ukraine issued a statement saying that the frigate «Hetman Sahaidachny» has not stopped taking orders from the Ukrainian government.

Read This Statement, And You'll Understand How Putin Sees Ukraine
Here is Russia's official statement on Ukraine. It's quite telling.
Some of the assertions provide insight into Vladimir Putin's view not only of the Kremlin-occupied peninsula of Crimea, but also of Ukraine as a whole. We've bolded four of them:
In recent days, the situation in Ukraine has deteriorated rapidly. The agreements reached between President Yanukovych and the opposition on 21 February have been scrapped by opposition leaders: the legitimate Head of State that was supposed to remain in office has been effectively ousted from the country, an interim president has been appointed, presidential elections have been set for 25 May, no steps have been made in the area of constitutional reform or joint investigation.
...
But more importantly, rather than taking account of the numerous appeals to national unity and reconciliation, political power in Kiev has been concentrated in the hands of far-right extremist elements that do not hide their xenophobic, anti-Semitic, neofascist credentials. Not surprisingly, one of the first decisions of the new rulers was to abolish the law on regional languages, a move that has caused concern not only among Russian-speakers, but also in Bulgaria, Romania and Greece. This has coincided with a widespread campaign of intimidation of ethnic Russian population and desecration of monuments celebrating Russia's and Ukraine's common historical achievements such as the defeat of Nazism in the Second World War. Russian Orthodox priests have become object of threats. Attempts were made to seize the Orthodox shrines, such as the Kiev Pechersk Laura and the Pochayev Laura.
The situation of the Russian community in the Crimea has become particularly precarious. As soon as rallies erupted to express protest against with the way the Kiev events had unfolded, the Crimeans were accused of separatism and were threatened with force. There has been a lot of speculation regarding movements of troops of the Russian Black Sea Fleet, taken as a precautionary measure in full compliance with the relevant bilateral agreements with Ukraine. During the night of 1 March, unknown armed men sent from Kiev tried to seize the building of the Crimea Interior Ministry. Only decisive actions by self-defence groups allowed to stop that provocation that has left many people injured.
...
Within this context, it is not surprising that as many as 143 thousand people from Ukraine have applied for asylum in Russia over the past two weeks.
...
Here's what the four bolded items mean.
1) The Kremlin has not recognized the new pro-West government in Kiev and is hosting ousted President Viktor Yanukovych in from the southern Russian port city of Rostov-on-Don. Last week Yanukovych told the press that he still considered himself be president and that "radical mobsters" had hijacked the government.
Putin appears to agrees with Yanukovych 's position of implementing the truce signed on February 19, which would have kept him in power until elections and was subsequently rejected by protesters.
2) New Ukrainian Prime Minister Arseny Yatseniuk doesn't look or sound like a bigoted neo-fascist. He did say on Monday that Ukraine will not allow Crimea to be split from the country.
"No one will give up Crimea to anyone," Yatseniuk told reporters.
Meanwhile, an increasing Russian troops are operating in Crimea, and they appear to be preparing for an occupation.
3) This assertion — that the Kremlin doesn't know the professional gunman that took over Crimean parliament and the regional government building — provides Moscow with plausible deniability.
At the very least, the pro-Russian gunman have been working alongside the more than 6,000 Russian troops operating in the peninsula.
"When we said we stand for the Russian language and Russia, they said: don't be afraid, we're with you. Then they began to storm the building bringing down the doors," a pro-Russian activist who watched the takeover of Crimean parliament told Reuters.
4) Crimea is the only region in Ukraine that has a majority Russian population. Putin considers Crimea, if not more of Ukraine, part of Russia since it was gifted to Ukraine in 1954.
Putin reportedly told President George W. Bush: “Ukraine is not even a state! What is Ukraine? Part of its territory is Eastern Europe, but part of it – a considerable part – was gifted by us!”
The Kremlin is consequently justifying the soft invasion as a means of protecting "the life and health of Russian citizens and compatriots on Ukrainian territory."
Additional confirmation of the Kremlin's cold calculus came when former Russian President and current Prime Minister Dmitry Medvedev stated that Ukraine's new government had seized power illegally and predicted that "a new revolution" and new bloodshed would upend it.
