Über mich

Fuer deutsche Sprecher:
Hallo,
ich bin Mathematiker aus Berlin und ein begeisterter Neuronale Netze Entwickler. Ich habe mich in den letzten Jahren ausgiebig in dieses Gebiet vertieft sowohl theoretisch im Rahmen meines Masterstudiums als auch programmtechnisch bei diversen Freelance Projekten. In meinem Masterstudium habe ich mich über eine sehr innovative Methode beschäftigt wie man Neuronale Netze als Differentialgleichungen ansieht was uns dann ermöglicht die gesamten mathematischen Tools von den letzten 200 Jahren auf Neuronalen Netzen anzuwenden. Dies ermöglicht viel interpretierbare und robustere Netze zu bauen, was momentan z.B. ein großes Thema bei selbstfahrenden Fahrzeugen ist. Mein breites Wissen in der Anwendungsmathematik ermöglicht es mir jedes Machine Learning/Big Data Problem professionell zu lösen und ggf. problemspezifisch fortgeschrittenere Algorithmen zu entwickeln. Um diesen Level zu erreichen habe ich fast das gesamte Feld der Anwendungsmathematik studiert: Numerics, Finite Element Methods, Optimisation Theory, Differential Equations, Statistics/Stochastics. Dieses Wissen hebt mich von den anderen Data Scientists ab, welche zwar Programmmodule bedienen können, allerdings kein tiefes Wissen haben um ein ernsthaftes Problem zu lösen, was zu oft auftritt und man begnügt sich mit suboptimalen Lösungen. Mein Ansatz ist hier etwas anderer: wenn nötig, greife in die Programmmodule ein und modifiziere dort den Programmcode wie z.B. Implementierung von custom layern in Tensorflow oder PyTorch, beides beliebte Neuronale Netze Module. Weiterer Ansatzpunkt von mir ist, nicht mit Kanonen auf Spatzen zu schiessen, sondern für jedes Problem die maximal einfache und effiziente Lösung zu finden, wofür ich das nötige Wissen habe. Das spart Zeit, Geld und Nerven. Um auf top aktuellem Niveau zu bleiben, besuche ich ständig Workshops und diskutiere aktiv mit meinen Kollegen. Ich bedanke mich bei Ihnen über mich gelesen zu haben und ich beantworte gerne jede Frage die an mich gestellt wird.

For English speakers:

Hello,
I am a mathematician from Berlin, Germany, and an excited Neural Networks programmer. I wrote my maths master's thesis on Neural Networks and Differential equations showing that Neural Networks are Differential Equations that help us to use the whole maths theory to find better and more stable Neural Networks being robust against adversarial examples. I love to go inside of the Machine Learning programs and understand every part of it, why it works well or bad and with the help of my immense mathematical understanding to improve it, if necessary. For this, I studied the whole bunch of applied Mathematics: Finite Element Methods, Optimisation Theory, Differential Equations, Statistics and Stochastics. This knowledge picks me up on others who only use the standard machine learning packages and are not able to create really robust and stable networks. Besides of that I love coding and implementing my ideas on Neural Networks if necessary improve Google's Tensorflow or PyTorch by writing APIs if they are not advanced enough. I constantly improve my Machine Learning/Big Data knowledge by active programming and visiting various workshops, seminars and university courses where I am actively discussing methods with my colleagues. That's about me, I will be thankful for every offer and for every question I will be glad to answer it!
