[Day 108] Recommender systems + small adjustment to the text2chart webapp

 Hello :)
Today is Day 108!


A quick summary of today:


Firstly, about the text2chart webapp

When I create the prompt for codellama, I give it info about the type of columns in the dataframe, using the below logic

It may not be the most robust, but it does fine for now. I thought a problem with the app is that the date column is read as numerical values, and tried to introduce the (now) commented if statement, tested it a bit and it did not seem to do anything.
Then, I decided to show the user what kind of code is being used to generate the shown graph (probably a feature I should have had from the beginning). And this actually made me realise that sometimes the generated code is actually not that good, so a more detailed query might be needed. 

Example:

So if a resulting graph is not good, we can see what was wrong in the code, and give a more specific query. However the downside is, is that if this were a final product, it requires python knowledge from the user, which is not ideal.

Secondly, recommendation systems

Covered topics:

Modern recommender systems, top-k recommendations, recall@K, embedded-based models for recommender systems, binary loss, Bayesian Personalised Ranking loss, GNNs for RecSys, Neural Graph Collaboration Filtering, LightGCN, PinSAGE (the paper of which I read on Day 100)

That is all for today!

See you tomorrow :) 


p.s. feeling a bit better today

[Day 198] Transactions Data Streaming Pipeline Porject [v1 completed]

 Hello :) Today is Day 198! A quick summary of today: data streaming pipeline project [v1 done] Here is a link to the project's repo. Well ... I did not know I can do it in a day (~14 hours) after yesterday's issues but here we are. Turns out in order to insert the full (~70 variables with nested/list structure), I need the proper pyspark schema. And yesterday I did not have that and that is why when I was reading data in the kafka producer I was getting NULL in the columns - my schema was wrong. Well today I not only fixed the schema for the 4 variables I had yesterday, but included *all* the variables that come from the Stripe API ~ 70 (for completeness).  When I run docker-compose, the data streams and is input into the postgres db (and is still running). Unfortunately, the free Stripe API for creating realistic transactions has a limit of 25, so every 3 seconds, 25 new transactions are sent to the db. It has been running half the day (since I got that set up) and as I am wr

[Day 107] Transforming natural language to charts

Image
 Hello :) Today is Day 107! A quick summary of today: created text2chart - transforming natural language to charts [ github ] [ webapp ] I am super sick, but in the around 3 hours of my fever not being high, I managed to study a bit. I was again thinking about creating some nlp project but was stuck on the idea of how to host a model. After looking around I found this article where they create a similar app called chat2vis  and they use codellama. I know codellama is an open source model that I can get from huggingface and I wondered, how did they host it. Turns out - they ask the user to input a huggingface api key, which then allows for querying and generating content. (AWESOME! this is applicable to some of the other PDF chat apps that I have, but I will look to make an app of them later).  My fever eased a bit, and I sat on my chair to do some work ^^ Here is a breakdown of the app. I used streamlit. Also, 2 default datasets during dev: Financial Statements of Major Companies(2009-

[Day 54] I became a backprop ninja! (woohoo)

Image
 Hello :) Today is Day 54! A quick summary of today: Read through cs231n's neural network lectures [1] [2] [3] Spent 8 hours going over Andrej Karpathy's backprop ninja tutorial After yesterday's confidence boost in doing backprop, I came in today with the intention of becoming of, as Andrej Karpathy calls it, a backprop ninja.  The cs231n NN lectures were the usual about how NN became to be, param initialization, activation functions, loss functions, regularization and optimizers. Nothing out of the ordinary, but still was good to reassure myself of that knowledge. But that was definitely not the main even of today. As I mentioned, I wanted to become (or at least attempt to become) a backprop ninja today. I have watched that particular tutorial twice, the 1st time I had no idea what is going on, the 2nd time I could follow, and now it was the 3rd time - and now, I wanted to participate and actually see the why and the how of the things we have to do, when we do manual back
