Map of corn on the cob street vendors in Mexico City.
I found this dataset. It can me exported to KML to parse and analyse. It's the crowdsourced geolocation of every corn on the cob street vendor in Mexico City.
I dare y'all to train a neural network on it!

R Statistical vs Deep Learning forecasting methods
​

Machine learning progress is plagued by the conflict between competing ideas, with no shortage of failed reviews, underdelivering models, and failed investments in expensive over-engineered solutions.
We don't subscribe the Deep Learning hype for time series and present a fully reproducible experiment that shows that:
1. A simple statistical ensemble outperforms most individual deep-learning models.
2. A simple statistical ensemble is 25,000 faster and only slightly less accurate than an ensemble of deep learning models.
In other words, deep-learning ensembles outperform statistical ensembles just by 0.36 points in SMAPE. However, the DL ensemble takes more than 14 days to run and costs around USD 11,000, while the statistical ensemble takes 6 minutes to run and costs $0.5c.
For the 3,003 series of M3, these are the results.

In conclusion: in terms of speed, costs, simplicity and interpretability, deep learning is far behind the simple statistical ensemble. In terms of accuracy, they are rather close.

[https://usf.az1.qualtrics.com/jfe/form/SV\_bBZrWNcr7zeg2fY?TID=59](https://usf.az1.qualtrics.com/jfe/form/SV_bBZrWNcr7zeg2fY?TID=59)
Hello,
My name is Joseph Regina and I am a doctoral student in the Industrial-Organizational Psychology program at the University of South Florida conducting doctoral research under the supervision of Dr. Tammy Allen. I am inviting you to participate in a study that focuses on the unique work challenges of same-sex presenting romantic couples related to making your relationship status known and is intended to inform organizations of LGBTQ+ family-friendly policies.
Notably, the study is three timepoints and will take you under 30 minutes (\~15 minutes for Time 1, \~10 minutes for Time 2, and \~5 minutes for Time 3) to complete. Additionally, as a token of our appreciation, you will have the chance to opt in to receive $10 in Amazon gift cards.
You are eligible for this study if you meet the following criteria:
* You are over 18 years old
* You work at least 30 hours per week for pay
* You are currently romantically involved in a same-sex presenting romantic relationship for at least 6 months
* You are not self-employed
* You work at an in-person work-related site for at least 20% of your workweek (i.e., not remotely)
* You work for a company with more than 5 employees
* Your workplace is geographically located within the United States
You may access the survey by clicking here [here](https://usf.az1.qualtrics.com/jfe/form/SV_bBZrWNcr7zeg2fY?TID=59). Participation is voluntary and you can withdraw from the survey at any time.
If you have any questions about this study, please feel free to contact me at [usfworkrelationships@gmail.com](mailto:usfworkrelationships@gmail.com) or [jregina@usf.edu](mailto:jregina@usf.edu).
Thank you,
Joseph Regina
