Identifying perceived emotions from people's walking style
A team of researchers at the University of North Carolina at Chapel Hill and the University of Maryland at College Park has recently developed a new deep learning model that can identify people's emotions based on their walking styles. Their approach, outlined in a paper pre-published on arXiv, works by extracting an individual's gait from an RGB video of him/her walking, then analyzing it and classifying it as one of four emotions: happy, sad, angry or neutral.
[...] The approach first extracts a person's walking gait from an RGB video of them walking, representing it as a series of 3-D poses. Subsequently, the researchers used a long short-term memory (LSTM) recurrent neural network and a random forest (RF) classifier to analyze these poses and identify the most prominent emotion felt by the person in the video, choosing between happiness, sadness, anger or neutral.
The LSTM is initially trained on a series of deep features, but these are later combined with affective features computed from the gaits using posture and movement cues. All of these features are ultimately classified using the RF classifier.
Randhavane and his colleagues carried out a series of preliminary tests on a dataset containing videos of people walking and found that their model could identify the perceived emotions of individuals with 80 percent accuracy. In addition, their approach led to an improvement of approximately 14 percent over other perceived emotion recognition methods that focus on people's walking style.

Sometimes my left knee hurts, sometimes my left ankle hurts. Sometimes my right knee wants to get in on the action. Or maybe I'm just tired from a long day, or not enough sleep.
In each case I'm sure my gait is different.
/ losing my left knee is how I ballooned from 215 lbs to 300 lbs
// it's genetic, mom had it, her mom had it, her brother had it, my sister has it
/// knee replacement is how you fix it, I'd rather be fat thankyewverymuch

I have a bad knee too and when it doesn't feel like I am walking with broken pieces of cartilage grinding or when my hyper extended MCL and kneecap decides to remind me of my snowboarding accident years ago, I go into a pool and swim laps. It's amazing actually the workout you get. Swimming is damn hard if you take it seriously. Even if you can't swim well, getting behind a flutter board and going at your own pace works wonders too. There are even bone conducting mp3 players you can wear for music inspiration or audio book listening while in the pool. It's also a major stress release just floating. You don't always have to go in free swim block time too with the screaming kids. There are adult swim times where it's really quiet and calming.
The only reason I'm mentioning that to you is because if you really wanted to, you could get back to a more healthier state that puts less stress on your knee and other joints. It will build up your strength too in ways other sports can't equal without wrecking your body. Not trying to shame you or anything, but rather just mention a path you could take that won't cause you more pain in your knee or elsewhere.
Think about it...it works.

Blew out my knees trying to run cross country in high school, probably due to a coach that didn't know anything about bio-mechanics (not blaming that coach, very few people knew that stuff in the late 1960s). Don't know exactly what went wrong, but my knees hurt a lot and I had sense to quit rather than "push through" the pain and do more permanent damage.
Anyway, bicycling works for me--as long as I pay attention to my position on the bike and make sure my knees track (roughly) in one plane (don't flop sideways). Cycling is a good workout and also a good way to run local errands--I hate the idea of sitting in a car just to get somewhere (gym) to exercise.
Back on topic, I wonder what the gait analysis looks like for cyclists walking in ultra-stiff-sole cleated shoes (many of these shoes lift the toes up relative to the heel). Sort of the opposite of teetering on high heels.

For folks with decent legs, a mixture of biking and walking/jogging is great. If you're jogging correctly, there should be as little up and down as possible. That's just wasted effort as well as something that's going to damage joints over the long term.

Basically, what you're saying is do they have a category for us called "Gimpy Ol Fucker"?
