I was working on implementing an R-CNN from scratch using Keras. I initially played with the Pascal VOC dataset without using batches and an information which you can retrieve is the number of objects in an image with len(data['objects']['label']) ; data being the output when you iterate one step through the dataset. Now I was trying to get serious about my project and I...

I have a problem installing keras in the Python version 3.12 using VSCode in an Asus Notebook running Windows 11.

The blog outlines an innovative approach to protect Australia's Great Barrier Reef using AI and machine learning. It describes the threat posed by crown-of-thorns starfish (COTS) to the reef and how traditional Manta Tow surveys are limited in efficiency and scale. The Great Barrier Reef Foundation, in partnership with CSIRO and Google, initiated a program to use underwater cameras and AI for more effective...
