6:00 PM | 33 UAV Experts Reveal Favorite Drone Accessory
I think we can all agree: The right drone accessories can make or break your flights. But there are tons of products to choose from. How do you decide which parts to buy? To get to the bottom of this, we asked 33 drone and UAV experts one question: “If you could only choose one drone accessory, which one would you choose and why?” We wanted to… Read more → The post 33 UAV Experts Reveal Favorite Drone Accessory appeared first on UAV […]

4:33 PM | Dictionary Learning with Few Samples and Matrix Concentration
Here are some theoretical developments for sparse coding, an item discovered experimentally twenty years ago. Dictionary Learning with Few Samples and Matrix Concentration by Kyle Luh, Van VuLet A be an n×n matrix, X be an n×p matrix and Y=AX. A challenging and important problem in data analysis, motivated by dictionary learning and other practical problems, is to recover both A and X, given Y. Under normal circumstances, it is clear that this problem is underdetermined. […]

5:00 AM | Tensor machines for learning target-specific polynomial features
Optimizing random features for tensors:Tensor machines for learning target-specific polynomial features by Jiyan Yang, Alex GittensRecent years have demonstrated that using random feature maps can significantly decrease the training and testing times of kernel-based algorithms without significantly lowering their accuracy. Regrettably, because random features are target-agnostic, typically thousands of such features are necessary to achieve acceptable accuracies. In this work, we consider the […]

7:47 PM | Update on rust-toys
With the release of rust 1.0.0-beta, I've received a ping about updating my code from 0.11. Unfortunately, I hit the following: let line : String = line.unwrap(); let line : &str = line.as_str().trim(); The variable line coming in is a io::Result (Is it me or are there two Result types in the standard library, std::result::Result and std::io::Result?); unwrap() returns a String (or blows up), which I then need to convert to a string slice (&str) in order to trim […]

6:05 PM | One stupid shell scripting trick everyone should know
Let's say that I am installing Rust 1.0.0.beta, which comes as a pre-compiled binary package with an install script. Now, this is probably a good thing, because building rustc from source was slow and the rustc source doesn't include cargo, and thus probably other nifty things, but it does have a downside: if you use the --prefix argument to set a local installation directory, say in your home directory, you get an error message running rustc. error while loading shared libraries: […]
