Soon there will be a ROCKETology the same way that NLP folks have the BERTology
Wow. Thanks for sharing @vrodriguezf!
And congratulations @angusde on your Time Series Classification SOTA. Very impressive!! The work you and your team is doing is superb, and so different from everything else in these area.
In the end weâll need to become rocket scientists to be able to apply your research!
Thanks for sharing the Zotero library, victor.
Also any cool dataset suggestions to just try out different classification models and learn parallelly? I was a forecasting guy mainly focused on statistical methods and now Iâm looking to get my hands dirty with deep learning for ts classification tasks.
All credit to Chang Wei here, this is essentially all his work.
development of methods to isolate the relevant signals in these convolutions will be highly productive
⌠Eagerly looking forward to it.
Authors , Thanks so much for your work.
PredictionDynamics for time series
Hi,
I just wanted to share a new, brief tutorial notebook Iâve uploaded to the tsai
repo to show how you can now use the new PredictionDynamics callback to visualize the modelâs prediction during training.
You can use it with any DL model (not just time series), in classification or regression tasks.
I think itâs useful to get a better understanding of how training is progressing.
This is the type of output youâll get during training (itâs updated at the end of every epoch):
wow thatâs really cool, thanks!!! I love this kind of interpretability tools! Btw can you share the blog post of Mr. Karpathy? The link of the notebook is broken
Would it be possible to see the evolution of that plot after the training has ended? Is it stored somewhere?
Thanks for your feedback @vrodriguezf!
Hereâs the link (Iâll fix it on the notebook).
I donât store the evolution anywhere as itâd probably slow down the process considerably. It takes 250 ms to update the chart, but to save is probably much slower. Iâll check it anyway. Something we could have though is an option to save it, knowing itâll make training slower. Whatâs your use case for storing the evolution? How would you use it?
Probably it only makes sense if behind of your training you are using an experiment tracking tool like weights & biases. That tool does exactly that, log things (e.g. the activations of your layers) for each training step, to allow a easy navigation through them afterwards.
I can think about and make a PR if I manage to spare some coding time
Meeting with Angus Dempster - Rocket, MiniRocket, and MultiRocket
Hi all,
Iâd like to invite you to participate in a web meeting weâll have with Angus Dempster next week (@angusde ).
For those of you who donât know him, Angus is a Ph.D. student at Monash University in Australia (a world-class group in time series research) and is one of the authors of several outstanding papers:
- Dempster, A., Petitjean, F., & Webb, G. I. (2020). ROCKET: exceptionally fast and accurate time series classification using random convolutional kernels. Data Mining and Knowledge Discovery , 34 (5), 1454-1495.
- Dempster, A., Schmidt, D. F., & Webb, G. I. (2020). MINIROCKET: A Very Fast (Almost) Deterministic Transform for Time Series Classification. arXiv preprint arXiv:2012.08791 .
- Tan, C. W., Dempster, A., Bergmeir, C., & Webb, G. I. (2021). MultiRocket: Effective summary statistics for convolutional outputs in time series classification. arXiv preprint arXiv:2102.00457 .
As you probably know, the ROCKETs have made a very significant impact in Time Series Classification and Regression. They are not only incredibly fast but have established a new SOTA!
Interestingly, the ROCKETâs use a very different approach compared to all other algorithms.
If you want to learn more about how they work and want to take the opportunity to ask one of the top researchers in the area of time series come and join us!
Date/ Time:
- February 10th (Wednesday) from 5:00 to 6:00 am Australian Eastern Daylight Time
- February 9th (Tuesday) from 7:00 to 8:00 pm Central European Time
- February 9th (Tuesday) from 1:00 to 2:00 pm Eastern Standard Time
If you are willing to participate, please reply to this blog post indicating so and I will forward you the link to the meeting through the forumâs email. Weâll use Google Meet.
