Theory, Code, and Exercises

We are in an ever-advancing industry, and learning resources are unlimited.

Last year I put together a compilation of ebooks that have helped me in my data science learning path and have been recommended by mentors and professors to solve specific projects or deepen concepts.

As I spent time deepening…

Last week over dinner celebrating the Chinese New Year, an acquaintance that is learning Data Science on his free time asked me how to formulate a problem worth to be solved with data and how to find the right dataset to practice his new skills.

We talked a bit about…

Example with NASA dataset

Exploratory Data Analysis (EDA) is, in my opinion, the most important part of Machine Learning Modeling in new datasets. If EDA is not executed correctly, it can cause us to start modeling with “unclean” data, and this is just as a snowball downhill, it gets bigger and worse.

Basic elements of a good Exploratory Data Analysis

The exploratory…

Bias and Variance are the core parameters to tune while training a Machine Learning model.

When we discuss prediction models, prediction errors can be decomposed into two main subcomponents: error due to bias, and error…

Un día desperté y pensé: “I’m going offline today.” Y así fue.

De Agosto a Noviembre desactivé mi perfil de Instagram y cuenta de Facebook por tres razones:

  1. Estaba ocupada haciendo esto, y comenzando Latinas in Tech Washington, D.C. Metro.
