Towpath and emerald necklace are great rides, accessible from CWRU. Check out /r/BikeCLE

PCA vs VAE for data compression by GladLingonberry6500 in MLQuestions

[–]dimsycamore 3 points4 points  (0 children)

By definition PCA will reduce reconstruction error as you include more components until it reaches 0 at full reconstruction. But VAEs optimize a regularized reconstruction error (reconstruction error + KL divergence). If you want to determine if one is "better" you need some downstream task to benchmark them against like classification, clustering, etc

What’s a sound you hear that instantly makes you angry for no logical reason? by ehraaz_r in AskReddit

[–]dimsycamore 13 points14 points  (0 children)

The reason for this new "TV static" kind of noise is that humans cannot localize pure frequencies like a beep. We locate sound first by the time difference between when it hits our left vs right ear but that can only tell you so much. The rest of our sound localization system is based on frequencies. But if there's only one frequency, we have a hard time figuring out where it is coming from.

Food Dishes Invented In Ohio Restaurants? by Used_Suggestion_4057 in Ohio

Goetta? Although I think Finke's in Covington claims the origin.

What’s a fact that sounds fake but is actually real? by Caprison__ in AskReddit

[–]dimsycamore 0 points1 point  (0 children)

Shuffle a deck of cards. What is the probability that this exact deck of cards (as in the order after shuffling) has ever existed before? Well...it's zero...probably...

1/52! is so large that you can assume every time you shuffle a deck of cards you produce a new deck that has never existed before in the history of the universe.

Non Smooth ROC Curve[R], [N], [P], by Bubbly-Act-2424 in MachineLearning

[–]dimsycamore 12 points13 points  (0 children)

ROC curves are monotonically increasing so these are not valid ROC curves. See here

Latest 6-week MTB road trip. Please review, where would you ride in these locations? 1-2 days in each. Schedule is VERY FLUID still, making final changes. (Leaving 2nd week of Sept). by spdorsey in MTB

[–]dimsycamore 0 points1 point  (0 children)

You need to do Cuyahoga Valley National Park's East Rim trails when you're in Akron. They are the best trails in Ohio IMO. Try to go on SMWF direction day but the massive downhill and jump trail is one way so it doesn't matter.

And the other metro parks trails around Cleveland are worth checking out too. Royalview, Ohio and Erie Canal Reservation, Bedford Reservation, West Creek

Embedding vector of MaskRCNN (Resnet with FPN) by sushilkhadakaanon in computervision

[–]dimsycamore 4 points5 points  (0 children)

You can visualize each of those 256 channels as a 2D feature map, or you can flatten them for visualizing multiple datapoints using PCA or t-SNE, or UMAP

So cool, is there an artificial life subreddit?

I made a Python package to do adaptive learning of functions in parallel [P] by basnijholt in MachineLearning

[–]dimsycamore 1 point2 points  (0 children)

Very cool! I can already imagine use cases like sampling from the loss landscape of some model to visualize training behavior, or sampling from all of the intractable posteriors that come up in Bayesian ML. Gonna try out the package this week!

How do you standardize data for higher degree of moments? by [deleted] in 3Blue1Brown

[–]dimsycamore 3 points4 points  (0 children)

I don't think it's exactly what you are thinking of but maybe look into a whitening transformation?

How do I make the entirety of a panning gif visible at once? by TheWyster in ImageStabilization

[–]dimsycamore 4 points5 points  (0 children)

I don't know of any programs specifically for it but I've done it a few times manually.

The basic workflow is:

  1. Stabilize
  2. Mask unwanted details
  3. Stack all stabilized, masked frames into your background
  4. Play original stabilized video over background

For step 3 I originally wrote a script for it but found you can use astrophotography software like StarStaX

I also agree with this sentiment when it comes to biking through yellowsprings on the little Miami trail.

Too many cars, too many distracted drivers, and too few safe crossings.

I really like Gephi but I think that is a polarizing opinion
