Fintech: Search for a super-algo

ai There has been a missuse or misundestanding about what Machine learning, a branch of AI, is. Generally,  many people relates the term AI to mean sentient computers as the ones in SciFi movies, but  in practice everyday tools such as Google’s language translation service, Netflix’s film recommendation engine or Apple’s Siri virtual assistant deploy rudimentary forms of AI.

 

In fact, an interesting view of ML and AI is posed by Matthew Dixon, assistant professor of finance at the Illinois Institute of Technology, who defines machine learning as an “optimisation machine that minimises chaos”. It can learn the difference between bananas and apples and sort them out, or even teach a computer how to play and quickly master a game like Super Mario from scratch. Machine learning can also be unleashed on “unstructured data”, such as jumbled numbers but also images and videos that are usually difficult for a computer to understand.

Machine Learning for Trading

Level: Intermediate

Hours: 6hs per week . Aprox. 4 months

Built by Georgia Tech

 

Course Description

This course introduces students to the real world challenges of implementing machine learning based trading strategies including the algorithmic steps from information gathering to market orders. The focus is on how to apply probabilistic machine learning approaches to trading decisions. We consider statistical approaches like linear regression, KNN and regression trees and how to apply them to actual stock trading situations.

Algorithms are changing business: here’s how to leverage them

 algoritFrom data to algorithms

With the advance of technology, companies and consumers are generating more and more data. Collecting and storing massive amounts of data is not enough to gain competitive advantage. In order to beat the competition, organisations must do more than simply analyse the data. It’s now about what actions you can derive from your data in order to add value. Bring in the algorithms…

R coming to Visual Studio

R Tools for Visual Studio (RTVS) follows the model of Python Tools for Visual Studio: it’s an open-source plug-in to Visual Studio that makes it a complete IDE for R, with syntax-aware editing, a command-line REPL, and interactive debugging. (Like PTVS, there will be a GitHub repo for RTVS when it’s ready for release.)

 

Visual Studio R

Of course, RStudio already has excellent capabilities for developing R code, and RTVS isn’t available — yet. But if you already develop in Visual Studio, or want to develop R code alongside C++, JavaScript, Python or any language supported by Visual Studio, send an email to RTVS-Invite@Microsoft.com to sign up for early access to RTVS.
