How can an activation atlas reveal hidden biases in CNNs by analyzing activations from multiple layers in complex images?

Wednesday, 03 December 2025 by JOSE ALFONSIN PENA

An Activation Atlas serves as a comprehensive visual tool that facilitates an in-depth understanding of the internal representations learned by convolutional neural networks (CNNs). By aggregating and clustering activation patterns from multiple layers in response to a diverse range of input images, the Activation Atlas provides a structured map that highlights how the network processes,

How can one use an embedding layer to automatically assign proper axes for a plot of representation of words as vectors?

Monday, 15 April 2024 by ankarb

To utilize an embedding layer for automatically assigning proper axes for visualizing word representations as vectors, we need to consider the foundational concepts of word embeddings and their application in neural networks. Word embeddings are dense vector representations of words in a continuous vector space that capture semantic relationships between words. These embeddings are learned
