A blog about MIt and my research
This is a followup to this post. I recommend you give it a read through before looking at this post. One of the interesting operational quirks of JanusGraph is that it has a storage layer and an indexing layer. This allow for graph traversals to be accomplished efficiently on the storage layer, while free text…
As part of my work as a data scientist, I have increasingly been using graph databases to represent person-centric and event-centric data. One of the more interesting graph data bases out there is JanusGraph. As the spiritual successor to titan, it has a lot of bells and whistles that make it interesting to scale to…
My wife (Sarah) has been spending a lot of her time building our her company. In the 21st century this means she is spending most of her time building out her company’s website (that you can see here: Science of Connectedness). To more directly target her audience, she had a need to take her Instagram…
Now that I have moved over to the corporate world, I have been doing a lot of development in R and RShiny. If you have not used it before, RShiny is an amazing tool for quickly creating scientific dashboards that are data-driven. With a little bit of knowledge of R and Web development, you can…
Hello All, As those who know me in person are aware, I will be defending my thesis here in March and will be leaving MIT in June. I started this blog as a way to keep track of my own research advancements and I have been blown away by how much help it has been…
A large part of computational material science is simply visualizing the input and output of our calculations. I use a variety of tools to do this including VESTA and Avogadro. While both have their strengths and weaknesses (VESTA is great for making publication-quality images, for example), Avogadro is very simple to use and quickly visualize…
In the past couple of months, we have been actively developing a machine learning method to learn charge-density functionals. We have developed this to map charge-density to a property of interest (such as the band-gap or some other property of interest). We are very excited about this code and I will be updating this site…
tl;dc: I have fixed an error in the QE module. Check out the new version here: http://www.levilentz.com/Codes/QE.Index.py Hello All, As you know, I have been working on and constantly expanding my QE module as I need to. You can read about it here, and here, and here. I started it about a year ago when…
Hello All, I wanted to provide another update on creating those cool plots that have both the band diagram with a cool pDOS plot next to it. This guide will build upon my previous guides that you may have found helpful. Check out my guide on pDOS plots here and my band diagram plot here….
Hello All, Just wanted to make a quick note if you are having issues compiling QE-gpu with GCC 5+ and CUDA 7.5 (CUDA 8.0 should support GCC 5+). I have been testing this now, and it does appear that CUDA works with GCC 5+ and QE despite the claimed incompatibility with GCC 5+. In order…
