binjr 3.12 is now available!

This is a pretty featureful release, whose highlight is a new indexing mode for log files that makes is easy to search for arbitrary strings of character without the need for wildcards while maintaining the same level of performance, even on very large files.

It also features several other smaller enhancements and many bug fixes: full release notes available at https://binjr.eu/download/CHANGELOG/#binjr-v3120

This R code serves as a great introduction to using the Shiny package for creating web applications and highlights the importance of model selection in forecasting. Give it a try and most importantly steal this code and see what you can do with it!

New (short) pre-print.

For time-series classification problems, we show that rock-bottom-simple models (that ignore the time-ordering of data!) can perform surprisingly well.
Some important general lessons for formulating and interpreting models.

Sometimes we want to look at a #bootstrapping #model and we can easily achieve this in #r even in #timeseries #modeling with the #forecast #package

In this post I used the AirPassengers dataset and used the auto.arima() function to bootstrap models, then I wanted to take a look at the residuals.

This is not comprehensive but sheds some light on how to do this outside of the #tidymodels #framework

InfluxDB runs on Debian ARM 64-bit, so that would probably work. However, how performant is it on a Zero W? Do I need a Zero 2 W? #RaspberryPi #InfluxDB #timeseries #microcontroller

I want to run a time-series database on a Raspberry Pi Zero W. What do you recommend? #RaspberryPi #database #timeseries #microcontroller

Are you familiar with recurrence analysis?

I recently learned about it and have some questions about its applications and limits.

(Is it used outside academia? If so, for what? What are its criticisms, if any?)

For the moment, we recommend to use the user-contributed #gretl package "auto_arima" written by @atecon .

Just to inform you:
The next release will include native support for #AutoARIMA automatically determining the optimal ARIMA #timeseries model specification.

This is will be pretty fast, as it's implemented in C.

I wrote about the design choice of single tables (with all data) and multiple tables (split by dimension); a common question for #timeseries data.
While the blog post is best-practices for #TimeScaleDB, the general sentiment behind the question is bigger!

Hi all, I’m a researcher working on brain-computer interfaces at Snap Inc.

My goal is to prove that noninvasive #BCI and #neurofeedback can provide value outside of the lab.

Currently for me that includes (but does not limit to) applying #deeplearning methods to #timeseries data like #EEG, but also other sensors like #eyetracking or inertial sensors (#IMUs)



Also a #python geek. I maintain an M/EEG analysis toolbox

#Introduction Hi y'all! I'm not a newbie to tech in general, but I often feel like a newbie due to the breadth and depth of technology, especially software (and infrastructure)!
I sort of fell into IT through a random job that promoted me based on a "logic" test. :D
I have experience in #C, #COBOL, some #ruby, a tiny old crumb of #java, but most recently #go / #golang. *NIX wins, imho. PC for home, Mac for work. Spent some time in the #cloud. The team I'm on for work is in a decent-sized retailer, and our focus is Observability. #influx #elasticsearch #grafana #timeseries and some cool home-grown products. We support internal customers (other teams and platforms), and I love answering questions!
I'm married to my lovely wife, and our babies all have fur. I live in a brick house built in 1888. I love old houses, even though there's not a right angle or standard size left!
If it's horror, I love it - movies, books, objects. I'm a little #goth at heart (though I'm an Old Bat now).
