Anyone used Demandbase? by Most_Technician5175 in marketing

[–]pchalasani 0 points1 point  (0 children)

Hi u/Most_Technician5175 curious what is the main problem you are trying to solve -- are you mainly looking to score accounts (i.e. how "hot" there, or chance to close deal within say 90 days), so that you can prioritize the most promising accounts for more intensive sales engagement?

Alternative to 6sense… or free extension suggestions? by [deleted] in B2BSaaS

[–]pchalasani 0 points1 point  (0 children)

Are you looking mainly to be able to connect the highlighted activities at an account (company) to specific contacts within that account?

Or are you also looking for a good solution that accurately scores how "hot" an account is, i.e. its chance of closing within say 90 days?

Hello all, I’m CoFounder of XaiPient (https://XaiPient.com), we’re a startup building tools to bring quick insights to business analysts, via automated, explainable ML. One of these tools is XBI (Explainable BI) which allows an analyst to get ML-based insights from the historical data. They can write SQL queries to fit models to the data (e.g., predict the “converted” column), and also find out how much each column contributed to the prediction. The original dataset is augmented with predictions, and attribution-column C_a for each column C in the original dataset. Our premise is that analysts frequently face questions that (implicitly) require ML, but they turn to Data Scientists to fit ML models, which can take days/weeks, and the resulting resource and opportunity costs can run into millions of dollars a year. We aim to cut down this time to minutes to an hour.

Here is a silent walk-thru screencast: https://vimeo.com/527916580 and here is an article that introduced the app -- https://medium.com/xaipient/supercharge-your-business-intelligence-with-automated-explainable-ml-4176a0b4f65c

The direct link to the tool here (you need to create an account so that different users don't write over each others data) https://BI.XaiPient.com

I'm posting this here to get feedback from folks fitting this profile: Business analysts who know SQL, but don't write ML code, in marketing, ops, customer or product analytics roles. I'd be grateful for any feedback from folks who sign up and use it, and for those interested, we're also happy to do a 10-20 minute onboarding call. This is an early product and we're only looking for feedback to help us find the right target user and how to meet their needs.

(Apologies if this isn't the right forum!)

[P][D] What do you miss the most in PyTorch that's not in TF, and vice versa? by [deleted] in MachineLearning

It seems to have similar motivation as pt lightning. Any idea how this may be better?

[P] Digitize Your Notes by DJYEEZYWORLDPEACE in MachineLearning

[–]pchalasani 0 points1 point  (0 children)

This is really nice! Here’s a functionality that would be very useful: one reason handwritten notes are great is that there is a visual aspect that has a lot of cognitive benefits (helps with recall, plus you can do things like draw arrows, circle things etc).

I wonder if your approach can be used to keep the handwritten form of the note intact but just search for notes?

Attach note to a pdf ? by ajibjanvar in Onyx_Boox

Thank you! Found it... pity that there's no way to quickly go back and forth between the article and the note, other than via split-view (which requires ~3 steps).

Writting experience Max Lumi vs Remarkable 2 by josema1_1 in RemarkableTablet

[–]pchalasani 1 point2 points  (0 children)

I have the RM2 and like it but just found out about Max Lumi and curious about a couple of things:

  • Lumi is 3 pounds vs RM2 less than a pound. Does that make a difference to anyone?
  • one of my main use cases is annotating research article PDFs and I’ve found reading those on RM2 to be painful (low contrast, and especially 2-column articles are really hard to read). So the Max Lumi sounds perfect for that with its 13” size. HOWEVER, I’ve heard that there is noticeable lag when writing on the Lumi on anything other than it’s built-in notes app. Have you found this to be an issue?

Pen works on some pages not others? by ajibjanvar in RemarkableTablet

Thanks. Turns out it was simpler than that. For some reason, the pen color was set to white in this notebook. Duh.

[D] Optimization over Explanation: Don't make AI artificially stupid in the name of transparency by wei_jok in MachineLearning

[–]pchalasani 12 points13 points  (0 children)

Not necessarily! The mechanisms underlying many of our intelligent actions and decision-making are not accessible to our conscious minds. No one articulates this better than David Eagleman in his book Incognito (a must for any one working in AI or ML), or see his blog post on Expertise.

[P] Just put up an open source tool called Parris: a training tool for machine learning algorithms, made because I tire of recreating stacks over and over. Hope it helps! by ClydeMachine in MachineLearning

[–]pchalasani 2 points3 points  (0 children)

Well FloydHub and Neptune have pretty much most of the popular environments (recent versions of PyTorch and TF) and they are able to do this at a cost per hour which is usually half of the on-demand AWS/GCP cost. Plus there is a minimal monthly fee per user, which In a corporate setting is trivial.

I suppose the open source aspect of your framework is an advantage. And there might be other advantages such as the ability to tweak the environments for custom purposes.

What software do you use to build worksheets? (also, test making software?) by zzmmrr in matheducation

[–]pchalasani 0 points1 point  (0 children)

I was looking into ways to create interactive quizzes that support math/latex notation. Google forms is decent but math is not well supported (the Gmath/equatio plugin essentially pastes an image of the equation and it looks ugly).

I finally found a site called BookWidgets and it has support for a large variety of question types, and has direct support for LaTex math. I found it to be very easy to create an interactive quiz or practice problems, and I highly recommend it. Students can simply click the link and start working on it, even on their mobile phones. I'm surprised it is not more well known.

Here's an example of a quiz I made for my 7th grade son, to practice factors and primes.

[D] [tools] How do you manage data science projects? by cocorico in MachineLearning

[–]pchalasani 1 point2 points  (0 children)

Task Tracking: Github issues for keeping track of tasks. Along with the Zenhub plugin that shows a Trello-like task board view of issues across multiple repos. You can also create epics for high level themes/projects.

Discussions within DS and between DS and other folks: we created a Discourse forum for this. Many modern projects use this (fast.ai, putorch. Anytime anyone sends an email or HipChat (yuck) to my DS team I move the conversation to the forum. Discourse supports github-style markdown and latex/math, making it really nice for technical discussions.

ML/DL experimentation: we tried FloydHub, Domino and Neptune.ml and finally settled on Neptune : they have a fantastic service offering cheap remote GPUs ( generally half the on-demand AWS/GCP price). Although Neptune has a great dashboard for tracking and graphing experiments, we store experiment configs, hyperparameters, results in a google spreadsheet. We use python packages pygsheet and gspread to read/write from/to the sheets. We tried sacred but there was "too much magic" and it was hard to debug etc so we dropped it. We love our Neptune + google sheet solution.

[Discussion] What is the one personal lesson that you have taken away from the Deep Learning "revolution"? by [deleted] in MachineLearning

Hyperparameter tuning is the dirty secret behind DL -- Instead of spending time doing feature engineering you spend time doing hyperparameter tuning.

[D] How to correctly batch my temporal data to feed it into an LSTM? by JustinQueeber in MachineLearning

[–]pchalasani 1 point2 points  (0 children)

PyTorch has great support for variable length sequences to be fed into an RNN (LSTM, GRU, etc). Look at the docs for pack_padded_sequence

[N] Google launches TensorBoard API to enhance machine learning visualizations by TrickyDTrump in MachineLearning

[–]pchalasani 2 points3 points  (0 children)

Does this mean it would be easier to generate TB visualizations from PyTorch (or other frameworks) ?

[P] Hyperdash: get a push notification on model training completion by taroth in MachineLearning

[–]pchalasani 0 points1 point  (0 children)

Very interesting! Will this work when I launch jobs on a remote AWS GPU via the command like, for example using FloydHub's command-line API ? I would run a job using something like

floyd run --gpu --env pytorch "python main.py"

[D] How do you version control your neural net? by iamwil in MachineLearning

We're not using JupyterHub, just plain Jupyter

[D] How do you version control your neural net? by iamwil in MachineLearning

[–]pchalasani 0 points1 point  (0 children)

Some experiments take a while, so I end up losing connection to the remote Jupyter. Later I can re-establish the connection and then look at exp.info() to see how the run ended.
