Melissa Santoslast day of work for a week. (I'll work the 30th, so not QUITE for the year)and my amazing "gift" from a colleague is 1500+ lines of example python for model building and preprocessing and validation! He writes beautiful, readable code too!I am _delighted_<a href="https://social.coop/tags/pydata" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pydata</a> <a href="https://social.coop/tags/merryChristmas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#merryChristmas</a>

Melissa Santoshere's a thought that someone has probably had before and I definitely don't want to implement myself: can we handle the inbalance in an ensemble method by sampling most of the trues, but a random set of the falses? so that the whole ensemble does use the full set of falses, but each tree has closer to balanced data? I am sure this is super naive in some way, but I'd love to hear what folks think, and , if this is a thing already, what it's called<a href="https://social.coop/tags/rstats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rstats</a> <a href="https://social.coop/tags/pydata" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pydata</a>

Mark SellorsI gave a talk last year on getting started with APIs for data scientists.

What's your favorite model type to use in this case? Do you resample the data to change the balance?

Tommi 🤯I spent the last two days coding <a href="https://codeberg.org/tommi/bepp" rel="nofollow noopener noreferrer" target="_blank">bepp</a>, my first <a href="https://pan.rent/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> project.Its use case that is so specific I think nobody else will ever use it except me.The tool is meant to clean up and merge together transaction summaries from <a href="https://bancaetica.it" rel="nofollow noopener noreferrer" target="_blank">Banca Etica</a> and <a href="https://paypal.com" rel="nofollow noopener noreferrer" target="_blank">PayPal</a>, exporting them in a simple <a href="https://pan.rent/tags/CSV" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CSV</a>.Even though it’s a tiny silly script, I am very proud of it and I feel that I could create anything I set my mind to, now!Thanks to my <a href="https://ois2.tlu.ee/tluois/subject/ULP6613-23265" rel="nofollow noopener noreferrer" target="_blank">Introduction to Data Science course</a>, that finally made me start learning Python with the time and dedication it deserves (<a href="https://github.com/alterism/mastodon-alt-text" rel="nofollow noopener noreferrer" target="_blank">my project for the course</a> is very interesting too, will post about it in a few days).<a href="https://pan.rent/tags/BancaEtica" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BancaEtica</a> <a href="https://pan.rent/tags/PayPal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PayPal</a> <a href="https://pan.rent/tags/PersonalFinance" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PersonalFinance</a> <a href="https://pan.rent/tags/PersonalFinanceManagement" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PersonalFinanceManagement</a> <a href="https://pan.rent/tags/pandas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pandas</a> <a href="https://pan.rent/tags/PyData" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PyData</a> <a href="https://pan.rent/tags/dev" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dev</a> <a href="https://pan.rent/tags/learning" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#learning</a>
