I am trying to change my career path back to a quant researcher after a decade of being in a different field (PhD and post PhD career has been in biotech). I wasn’t a quant for a very long time either. Thus I feel like I need to rebuild my quant portfolio – and I felt Kaggle competitions would be a good way to do that. As luck would have it, the current Jane Street competition isn’t allowing new entrants and the older one doesn’t have the data available any longer.

Is there a way to access the data of the JS competitions – either the new one or the old one?

Any help is much appreciated.

Hi everyone, this is kind of a long shot but I really need the National Survey of Children’s Health datasets from 2016-2023. I am writing a thesis-type paper for my Master’s program and after working really hard on my proposal, I go to download the data from the US Census Bureau and realize it’s all gone. Not sure if this is because of executive orders but I can’t find the data ANYWHERE. So if anyone has the micro data files downloaded for NSCH any years between 2016-2023 and would be willing to email them to me I would be so appreciative!!

Nexar just released an open dataset of 1500 anonymized driving videos—collisions, near-collisions, and normal scenarios—on Hugging Face (MIT licensed for open access). It’s useful for research in autonomous driving and collision prediction.

There’s also a Kaggle competition to build a collision prediction model—running until May 4th, results will be featured in CVPR 2025.

Regardless of the competition, I think the dataset by itself carries great value for anyone in this field. If you’re interested in the details, feel free to ask or reach out!

Disclaimer: I work at Nexar. Regardless, I believe a completely open and free dataset of labeled anonymized driving videos is helpful to the community.

Hi everyone,

I’m looking for a dataset containing lots of low-quality online comments specifically a mix of:

Spammy ads(“Hot singles in your area!”, “Earn $500/day from home using X!”) Conspiratorial rants(“The government is hiding the truth about birds!”) and Poorly written, nonsense comments

Hello. I’ve been trying to access an IPUMS (.CSV) data using Python, but it’s not letting me. I would like to view the first 1000 rows of data and all columns (independent variables).

So far, I have this:

import readers

import pandas as pd

import requests

print(“Pandas version:”, pd.version) print(“Requests version:”, requests.version)

ddi = readers.read_ipums_ddi(r”C:UsersjennyDownloadsusa_00003.xml”) ipums_df = readers.read_microdata(ddi, r”C:UsersjennyDownloadsusa_00003.csv.gz”)

iter_microdata = readers.read_microdata_chunked(ddi, chunksize=1000)

df = next(iter_microdata)

…

What am I doing wrong?

Or something that is on education on issues about aging. Needs to be publicly available and qualitative.

Technically I am looking for something psych based. But I don’t know what I’ll be able to find so I’m flexible.

I’ve been trying to track down the correct links but have run into some difficulties and outdated links. The datasets I’m looking for are:

CoNSeP Kumar CPM-15 CPM-17 TNBC CRCHisto PanNuke MoNuSeg

I’ve seen some references to these being available on platforms like Zenodo, GitHub, and challenge websites (e.g., Grand Challenge), but I’m not sure which are the most up-to-date or official sources.

Some information on the datasets:

CoNSeP: Often linked via the University of Warwick’s datasets page or the Hover-Net GitHub repository. Kumar: There’s a Zenodo link I came across, but I’m not 100% sure if it’s still active. CPM-15 & CPM-17: These appear to be hosted on their respective challenge sites, likely requiring registration. TNBC: Information is a bit sparse; sometimes it’s available via publication supplements or by contacting the authors directly. CRCHisto: I believe it’s on a challenge website (possibly under Grand Challenge) with registration required. PanNuke: I’ve seen links to GitHub and Zenodo, but I’m uncertain which is the current official source. MoNuSeg: I know it’s associated with the Grand Challenge platform, but again, I’m having trouble confirming the latest access instructions.

Has anyone successfully downloaded these datasets recently or know where I can find the official, up-to-date links?

Hello. We have a group research project due soon but we are in urgent need of data. My partners and I decided on talking about what affects the cost of life insurance and how. We will be using an econometric model in order to obtain the B0, B1-B10 (approximately). So, that means we need the raw data of individuals living in the United States in order to create a regression model. However, if there’s nothing for life insurance, anything else related to economics could work. We definitely might have to change the topic to whichever topic gets us at least 1000 rows of data (with at least 10 independent variables, columns) the fastest.

So, where can I get this sort of information?

Need a dataset with timestamps where a topic is constrained to sort of like how some Youtube creators’ videos has timestamps of when they’re speaking on a topic or reacting to something. For more context like Reacting to political video 9:00 – 23:00 etc…

no restriction of which platform the data is from

Hi everyone,

I’m working with a dataset of trees where some entries are classified at the Genus level and others at the Species level. I’m looking for a comprehensive database that includes detailed taxonomic information—specifically family, genus, and species relationships for a wide range of trees.

I found a website that might allow API requests, but I’d prefer an offline dataset (CSV, JSON, etc.) if possible.

Does anyone know of publicly available databases or resources that could help? Any suggestions would be greatly appreciated!

Thanks in advance!

Hello everyone, my team and I are working on a deep learning project aimed at predicting chronic diseases in individuals using a trained model. To do this, we are looking for datasets from people’s wearable health devices. Personally, I use an Apple Watch and have access to my own data, but I am also interested in finding public datasets. Does anyone have any suggestions on where I can locate such

Hey folks, I’m on the hunt for a solid dataset with a ton of leaf images. No extra metadata, no environmental data—just pure leaf pics. Ideally, it should have a variety of species and different angles, but I’m not picky beyond that.

Anyone know of any good publicly available datasets? Would really appreciate any leads! 🚀

Ideally of non-white populations.

Hello. I am looking to practice my SQL skills as I want to stay sharp. I am looking for small datasets to upload into sheets and then ultimately BigQuery to practice the basics. Any suggestions as to which free datasets to use? Everything suggests BIG BIG BIG! I want to stay small and manageable, but just enough in there to try functions and joins and transforms and the like. Thank you.

Hey guys! I want to work on a project with restaurant information gathering, with detections and tracking.
I want to start my project small ,so im just thinking looking for a cctv footage from restaurants, if its records the enterance and has more cameras from the same restaurant that would be awsome. I think 1-2 hour would be good to start training or just for start to get familiar.
If anybody knows where can i found these i would be very appriciate that!

Hey Guys,

and any option how i can get subscription for crunchbase as a student

I have coordinates within the USA. Ideally trying to recreate this at scale: https://screencapturePL.tinytake.com/msc/MTA1NjIxMjlfMjQyNjM2MTU

But a poor man on a budget. This data is commonly freely available at the state DOT level for small roads. For highways and national routes you can get it from USDOT sources.

Any and all advice?

Hi,

Navigating the complexities of dataset acquisition for my PhD research has proven challenging, particularly with the VGGSound dataset. Despite my extensive efforts, I’ve encountered significant roadblocks in downloading the required audio files. While the GitHub repository speedyseal/audiosetdl suggests a straightforward download method with the command python download_audioset.py, both for VGGSound and audioSet, the actual video retrieval has been thwarted by unavailable resources. Ironically, recent ICLR 2024 publications reference this dataset.

If anyone can help, that would be awesome. Thanks
