Artificial Indifference
dezembro 12, 2024 § Deixe um comentário
In the previous essay (The Artificial Other), we explored how the risks associated with artificial intelligence often mirror elements of human hubris, much like Timothy Treadwell’s ill-fated immersion into the wild, as depicted in Werner Herzog’s Grizzly Man. Treadwell’s story is one of passionate yet misguided engagement with Alaskan grizzly bears — a world governed by the harsh and indifferent logic of nature. His overconfidence in his ability to connect with these creatures on his own terms ultimately led to tragedy. It serves as a poignant reminder that nature, as majestic as it may be, operates without regard for care, justice, or morality. It is neither good nor evil; it simply exists. This unyielding indifference, captured so vividly by Herzog, underscores a deeper and more unsettling existential truth: humanity’s inherent vulnerability to forces beyond its control.
LLMs: The Wall Is Now a Mirror

From The Information — Dec 5th 2024
Back in November, I wrote about how Large Language Models (LLMs) seem to be hitting a wall. My piece, “LLMs Are Hitting the Wall: What’s Next?”, explored the challenges of scaling these models and the growing realization that brute force and larger datasets aren’t enough to push them closer to true intelligence. I argued that while LLMs excel in pattern recognition and syntactic fluency, their lack of deeper reasoning and genuine understanding exposes critical limitations.

Prediction Assignment – Practical Machine Learning
novembro 11, 2016 § Deixe um comentário
To those whom are eager to know more about Machine Learning and how it goes in a real life work, I share a paper I wrote with analysis, codes and algorithms of a Machine Learning Prediction Assignment. I wrote the codes in R, which is a statistical programming language. I also would like to thank PUC-Rio for providing the dataset that I worked.
Executive Summary
Using devices such as Jawbone Up, Nike FuelBand, and Fitbit it is now possible to collect a large amount of data about personal activity relatively inexpensively. These type of devices are part of the quantified self movement – a group of enthusiasts who take measurements about themselves regularly to improve their health, to find patterns in their behavior, or because they are tech geeks. One thing that people regularly do is quantify how much of a particular activity they do, but they rarely quantify how well they do it. In this project, your goal will be to use data from accelerometers on the belt, forearm, arm, and dumbell of 6 participants. They were asked to perform barbell lifts correctly and incorrectly in 5 different ways.
Data source
The data for this project came from the Human Activity Recognition study, conducted by Pontifícia Universidade Católica – Rio de Janeiro.
