Adaptive Gradient Algorithm

Dataconomy

The Adaptive Gradient Algorithm (AdaGrad) represents a significant stride in optimization techniques, particularly in the realms of machine learning and deep learning. What is the Adaptive Gradient Algorithm (AdaGrad)? Its innovative mechanisms quickly gained traction among researchers and practitioners in the field.

Understanding Reinforcement Learning and Multi-Agent Systems: A Beginner’s Guide to MARL (Part 1)

Towards AI

A popular algorithm used for training a single agent is the Q-learning algorithm. The algorithm works by helping the agent estimate a reward from performing different actions in different states.

You need much less memory than time

Hacker News

Williams proof relies on a space-efficient tree evaluation algorithm by James Cook and Ian Mertz from last years STOC conference. Cook and Mertzs algorithm builds on earlier work on catalytic computing, highlighted in a recent Quanta article. Williams then applies the tree evaluation algorithm of Cook and Mertz.

A non-anthropomorphized view of LLMs

Hacker News

The surprising utility of LLMs LLMs solve a large number of problems that could previously not be solved algorithmically. We cant, currently, and that sucks, but at the heart, this is the mathematical and computational problem wed need to solve. NLP (as the field was a few years ago) has largely been solved.

HyAB k-means for color quantization

Hacker News

I’ve been obsessing over color quantization algorithms lately, and when I learned that an image conversion app called Composite did its so-called pixel mapping step in CIELAB space, I instantly thought of the “HyAB” color distance formula I’d seen in the FLIP error metric paper from 2020. Consider the “max coverage” algorithm from Pillow.

Minimal Boolean Formulas

Hacker News

rsc Thoughts and links about programming, by Russ Cox RSS Minimal Boolean Formulas Posted on Wednesday, May 18, 2011. The program I wrote was a mangling of the Floyd-Warshall all-pairs shortest paths algorithm. The new loop in Algorithms 3 and 4 considers each pair f, g only once, when k = size(f) + size(g) + 1.
