Two tiny functional VIs

Monday, July 14th, 2014

For the last a few months I am still learning Machine Learning with LabVIEW (which might not be the best language for ML) and doing more signal processing jobs. I tried to follow some MOOC courses on R and Python to master better tools for ML. Really got some to-do projects in my mind and want to implement them soon.

Since I am dealing with a lot of file loading recently, this vi was built to scan a folder to find the file starts with the specific string. This is nothing complicated and I am sure there is a simpler solution. But here is an example of the implementation:

Find file starts with the name

It iterates the names of the files and quits if finds the name starts with the “Start with” string.

Another function is “Random selection from elements“. It allows the user to randomly select from their own dataset, which could be a number of integers, strings or any other data types. Again this is very simple but I found it quite useful in many “simulation” applications.

random element

The input array can be replaced by any other types of arrays. It is worth mentioning there is a “Riffle.vi” in LabVIEW that can randomly disorganize the input elements (so the output is a disorganized array). The randomness can be repeated by setting the seed to the same number.

 

 

A quick update for the Flappy Bird project

Monday, April 7th, 2014

It seems last post was found by @labview and brought much visiting here. So this project is still undergoing and I was kind of busy this month. But I will try finish this ASAP 🙂

Here are some updates since last post.

An Arduino controlled stylus now can be controlled by clicking the mouse.

There is a tip that the stylus needs to be earthed (via the red wire) to take affect.

And the Flappy Bird game is (poorly) simulated on LabVIEW. So I simulated FB (not facebook!) on LabVIEW to test the Q-learning algorithm in a purely software environment. Now it can pass 5 gaps 🙂 The algorithm needs to be altered a bit and then I will integrate the whole things.

New year, new job

Thursday, January 2nd, 2014

Hi all, hope you had a wonderful Christmas and a happy new year. It’s been 4 months since last post and something changed in my life. I started a new job in a LabVIEW consultancy company based in London. I always love London, in which there are so many places to explore.

So have to say goodbye to the lab and neuroscience. I am doing signal processing with LabVIEW now. It sounds fun and can be a good opportunity for me to learn more about machine learning and advanced LabVIEW programming. I will keep updating the blog and am thinking if I should change the blog title to some more general one 😉 (Let machine learn? Let lab wow?).

All the best.
