Abstract: Vector-quantized representations enable powerful discrete generative models but lack semantic structure in token space, limiting interpretable human control. We introduce SOM-VQ, a tokenization method that combines vector quantization with Self-Organizing Maps to learn discrete codebooks with explicit low-dimensional topology. Unlike standard VQ-VAE, SOM-VQ uses topology-aware updates that preserve neighborhood structure: nearby tokens on a learned grid correspond to semantically similar states, enabling direct geometric manipulation of the latent space. We demonstrate that SOM-VQ produces more learnable token sequences in the evaluated domains while providing an explicit navigable geometry in code space. Critically, the topological organization enables intuitive human-in-the-loop control: users can steer generation by manipulating distances in token space, achieving semantic alignment without frame-level constraints. We focus on human motion generation - a domain where kinematic structure, smooth temporal continuity, and interactive use cases (choreography, rehabilitation, HCI) make topology-aware control especially natural - demonstrating controlled divergence and convergence from reference sequences through simple grid-based sampling. SOM-VQ provides a general framework for interpretable discrete representations applicable to music, gesture, and other interactive generative domains.

"A Palestinian children's football club in the occupied West Bank faces imminent demolition despite an international campaign to save it. Its supporters say it provides a rare sporting opportunity for young Palestinian players.
"But Israel insists it's been built without the necessary permits."
As I understand it, such permits are rarely given.
It's on land supposedly under the control of the Palestinian Authority in occupied Palestine.

Palestinian football pitch faces Israel demolition ultimatum
The football club is ordered to remove the pitch, which Israel says was illegally built, or have it torn down.

The BBC running damage control on its own broadcast is wild to witness. The most egregious part of the affair to me is that no one from BAFTA or the BBC even bothered to apologize to Michael B Jordan and Delroy Lindo when they got off the stage, let alone tell *them* what was going to be done about it. There was no effort to bring the three people involved together for resolution at the time of the incident, nothing.
But the other part of this that just grates on me with every article is the BBC trying to defend itself by saying “that another racial slur had been edited out of the broadcast.”
