If you plan to pivot to other areas of data or tech in general and you're confused, don't know the skills to learn or you want to know about the field you're pivoting to, the link above provides all the necessary information you'll need and more.

@Rahmanda__21 It’s absolutely worth it.
I was a data scientist and more of a ML engineer too.

Always check for outliers first.
Without proper outlier filtering, the accuracy of your machine learning model can be significantly affected.
You can visualize this using a box plot to easily identify data points that fall outside the expected range.
After handling outliers, apply standardization to ensure all features are on the same scale.
Clean data first. Then build the model.
Don’t be surprised I started my career as a data scientist and was trained by @dsn_ai_network way way back.
Saw your tweet and decided to jump on it.

Data cleaning is underestimated That’s where the real work is.

Not after reading. Now.
At some point, you will build a payment system, work on one, or inherit one that is already broken.
When something goes wrong, and it will, you will need exactly what I am about to show you.
This is the most complete payment system breakdown I have ever written.
Every flow. Every edge case. Every trap. One thread

@Rahmanda__21 Go home, rest and open your system
You aren't quitting

Honestly, the person who created subqueries in SQL doesn't have a happy home 🥲 Which do you prefer? Subqueries or CTEs

Whenever I look at the healthcare dashboard of many analysts on X
I laughed 😂😂 because healthcare is not something you can jump into like that; you need some basic knowledge, bro ooo…
I have been analyzing this air quality dataset for like 2 weeks now, I am yet to wrap my mind around the whole scenario because “it is a health-related “ and humans are the price!!
Statistics is driving me to where I don't know but I am enjoying it like 🔥
There are some things called parameters, KPIs in the healthcare system that are very dangerous and questionable.
Pardon me, I am just a random environmental analyst 😂 I am more about your health and the environment

Day 20 of restarting my data analytics journey. Today i didn't move to a new topic. Instead i took a step back and decided to test my knowledge on some of the topics i've learnt so far including yesterday's topic. I saw progress. Hoping to stay consistent💪
