https://aws-startup-lofts.com/amer/program/accelerators/generative-ai

Hey HackerNews,My team at AWS is launching a 10 week Generative AI accelerator program. Applications are due April 17th.Cohort participants will receive $200,000 in AWS Promotional Credits, and may receive up to $100,000 in AWS Activate credits.10 weeks of mentorship from top AI/ML industry leaders and technical support from AWS product teams while you build and refine your Generative AI...

dendron looks slick. not personally an early adopter when it comes to note taking apps, but might try this out.
I'd recommend using DynamoDB for your database.

Best of luck.

Looks helpful. Interested to see how the product features stack up compared to Google Colab.

That is interesting. I"ll have to explore that correlation and make sure that we have a good baseline comparison for the v2.0 model.

Thanks!

Thanks for the feedback Jake!
Re:The Saltiest Users on HN on Saturday April 20, 2019 @07:36PM (#19709597)
Actually, username & story titles aren't included in the model. We may experiment with including them in the future but for now we left them out to avoid any undo bias.

Sweetest users is a good question. I'll have to build out that view some time.

Re:The Saltiest Users on HN on Saturday April 20, 2019 @07:32PM (#19709585)
For this version we used TextBlob out of the box with some custom weighting to avoid false positives.

We'll relaunch in about two weeks with an improved model that we're currently training on a much larger labeled dataset and SOTA BERT model. :)

TYVM.

This kind of feedback gets me pumped about continuing to work on it.

Your account is pretty new. We intentionally remove any accounts with less then ? number of comments to discourage people from attempting to set a record. Lol

Broadly applied definition, weakly defined.
Re:The Saltiest Users on HN on Thursday April 18, 2019 @02:12PM (#19693346)
Sorry about that, and thank you for the feedback. I'll try to make sure it is more readable in the next version. Thanks for taking the time to check it out!
Re:The Saltiest Users on HN on Thursday April 18, 2019 @02:10PM (#19693326)
This sounds interesting. I like it.
Re:The Saltiest Users on HN on Thursday April 18, 2019 @02:09PM (#19693310)
Yeah, it really thinks code is salty for some reason....

The Muffin Tops part is making me lol.

Re:The Saltiest Users on HN on Thursday April 18, 2019 @02:07PM (#19693289)
We used TextBlob for this one and penalized to help avoid false-positive classifications for saltiness (subjectivity + negativity).
Re:The Saltiest Users on HN on Thursday April 18, 2019 @02:05PM (#19693268)
You're spot on. This model is based off a dictionary with scored words!

For the curious you can see the dictionary here: https://github.com/sloria/TextBlob/blob/eb08c120d364e9086467...

The package used is a pretty popular one called TextBlob. It is nifty for working with unlabeled data like we have with the HackerNews dataset.

We really focused our definition of saltiness around being a combination of (subjective + negative) comments.

We reduced the impact of (objective + negative) as we feel that criticism, while at times painful, if presented objectively isn't necessarily salty.

We built this model fast (1 week) and have since iterated this week into developing a Fine Tuned BERT model that we are training over a much broader set of toxicity, demographic, and polarity features. The training set is much larger and higher quality so we are expecting a large jump in precision upon deployment.

I hope the app gave you some good chuckles as you went around though. It's hard to explain how excited I felt when I saw pg_is_a_butt at the top of my pandas data frame the first time I processed the data.

It's doing a little bit right. :)

Re:The Saltiest Users on HN on Thursday April 18, 2019 @01:42PM (#19693047)
Oh that's strange! Yep. Need to fix that! Good catch, thanks!
Re:The Saltiest Users on HN on Thursday April 18, 2019 @01:40PM (#19693030)
I agree. Would have been much easier too. Unfortunately, HN doesn't have downvotes. The current model does incorporate upvotes, but we're seeing a lot more success training with like-kind labeled datasets + BERT fine tuning.

Thank you for trying the app and hopefully V2 will leave you feeling like the system is more precise.

Re:The Saltiest Users on HN on Thursday April 18, 2019 @01:36PM (#19692990)
Thanks for trying my app! And thank you for taking the time to respond!

It does have a LONG way to go. These are valid criticisms. And all areas we are working to improve on with our next ML model. (Sad vs Negative, rating numbers as "salty",

This model is pretty simple. It's using TextBlob and looking for a combination of negative sentiment (not necessarily condescending) and subjectivity. Essentially hand built heuristics derived by weighting each word in the sentence. Not a great way to make predictions.

The model is FAR from great. But great from afar. For high level (overall user saltiness) it performs better.

The unlabeled dataset of this size presents some unique challenges but in our testing of our new model (based on SOTA BERT fine-tuining & a large labeled training dataset) the results look promising. I'm really looking forward to getting it deployed.

I am encouraged by the words of @pg who said "you can and should give users an insanely great experience with an early, incomplete, buggy product, if you make up the difference with attentiveness.

Can, perhaps, but should? Yes. Over-engaging with early users is not just a permissible technique for getting growth rolling. For most successful startups it's a necessary part of the feedback loop that makes the product good. Making a better mousetrap is not an atomic operation. Even if you start the way most successful startups have, by building something you yourself need, the first thing you build is never quite right. And except in domains with big penalties for making mistakes, it's often better not to aim for perfection initially."

I’m glad you like it! I think we all have room to improve.
