[Mllab] Diffusion Maps Zettel
by Bastian Bohn 03 May '18

03 May '18

Hi, danke an Lisa für das Überarbeiten des Diffusion Maps Zettels. Finde ihn jetzt gut gelungen. Einzig die Vorverarbeitungssachen fallen noch ein bisschen vom Himmel, aber ich wüsste jetzt auch nicht, wie man das besser machen könnte. Ist auf jeden Fall jetzt sehr rund und verständlich alles. Ich werde die Tage noch Kleinigkeiten editieren (Nomenklatur ein bisschen an die vorherigen Zettel anpassen, etc.) und hab' nur noch 2 kleine Fragen: 1.) Beim single-cell qPCR Datensatz steht, dass die Zahlen CT-Werte sind. Was sind die einzelnen Matrix Einträge denn genau? Kann man das in 1-2 Sätzen für Laien erklären oder ist das zu kompliziert? 2.) Beim De-Meaning, wo der Mean von Actb und Gapdh abgezogen wird: Was ist konkret mit mean(x_{ig_{Actb}}, x_{ig_{Gapdh}}) gemeint? Ist das einfach 0.5 * (x_{ig_{Actb}} + x_{ig_{Gapdh}})? Vielen Dank schonmal und ein schönes Wochenende.

[Mllab] Fwd: Re: Attend to Practical Lab

-------- Forwarded Message -------- Subject: Re: [Mllab] Attend to Practical Lab Date: Thu, 26 Apr 2018 15:46:36 +0200 From: Eric Hahn <eric00hahn(a)gmail.com> To: Bastian Bohn <bohn(a)ins.uni-bonn.de> Dear Dr. Bohn, as a bachelor student in mathematics one is allowed to register via BASIS for the master lab - I will do this now. However it is not so easy to register for master modules in computer science as a mathematics bachelor (which I planned to do instead). This is of no importance. I just wanted to give the reason why I am asking so late.
