Primera experiencia de hacer referee report con IA: mala. Me hace decir cosas que no entiendo y no estoy dispuesto a decir, me hizo perder tiempo. Seguiremos participando.

Vehículo con sistema de ocultar la placa, atrás una unidad de tránsito de la CTE.
En el puente de la Unidad Nacional llegando a Durán.
Saben que pasó? Exacto, nada.
Gran oportunidad para la investigación económica en #Ecuador gracias a la @aso_econ_ec. También para el reencuentro con los amigos/colegas, ideas y la presencia del maestro @jmwooldridge .
Gracias al anfitrión @UDLAEcuador.
#WorldCup forecast (Wooldridge approved): 🇪🇨🏆
Our paper “Difference-in-Differences Designs: A Practitioner’s Guide” is now published in the Journal of Economic Literature. It took us a while but we are happy!
We put together a lot of material to make the paper useful in practice: https://t.co/30TbAgihlz
Hope you like!
Hoy fue celebrado en la FCNM de ESPOL el #Diadelamujermatemática, efectuando un interesante conversatorio en el que mayoritariamente intervinieron alumnas, graduadas y profesoras de la carrera en Matemáticas, implantada en la ESPOL desde 2016.
El problema es que por más puertas que toqué para financiar los gastos, entre grandes empresas y bancos, la respuesta siempre fue: "no apoyamos este tipo de cosas"... https://t.co/VZerxqhCO8
Holy shit… someone just made machine learning click.
Not static diagrams.
Not math-heavy PDFs.
Not black-box training.
Real algorithms — training step-by-step — visually.
It’s called Machine Learning Visualized
and it lets you watch models learn in real time.
Here’s why this is different:
Instead of dumping theory first,
it shows optimization happening live:
• gradients moving
• weights updating
• decision boundaries shifting
• loss decreasing
• models converging
You literally see learning happen.
Everything is built from first principles:
• Gradient Descent
• Logistic Regression
• Perceptron
• PCA
• K-Means
• Neural Networks
• Backpropagation
No magic. Just math → code → visualization.
Each chapter is a Jupyter notebook
that derives the math
then implements it
then animates training.
So you can watch:
• neural nets shape decision surfaces
• PCA rotate feature space
• K-means clusters form live
• gradient descent find minima
• sigmoid reshape boundaries
• backprop update weights step-by-step
This solves a huge problem:
Most ML resources teach: math → code → ??? → trained model
This shows: math → code → learning process → result
Which means you finally understand:
• why gradients matter
• how weights evolve
• what loss landscapes look like
• how convergence actually happens
• why deep nets learn non-linear functions
Even better:
You can open any notebook
modify parameters
and watch behavior change instantly.
Learning ML becomes interactive.
Not passive.
Not abstract.
Not confusing.
Just… visible.
Perfect for:
• beginners learning ML
• devs moving into AI
• interview prep
• teaching concepts
• understanding backprop
• visual learners
• building intuition
This is the kind of resource
that makes neural networks finally “click”.

We’re moving from:
reading about ML
→ watching ML learn
That’s a big shift.
Because once you can see training,
you stop memorizing… and start understanding.
AI education just got visual.
