SIGReg demo

Runnable PyTorch implementation of the Sliced Isotropic Gaussian Regularizer (SIGReg) from the LeWorldModel paper (Maes, Le Lidec, Scieur, LeCun, Balestriero, arXiv:2603.19312, March 2026).

SIGReg is a single-term regularizer that replaces the usual six-knob stack (EMA teachers, stop-gradient, frozen pretrained features, VICReg variance/covariance terms, momentum encoders, LR warmup schedules) used to prevent representation collapse in JEPA-style self-supervised world models.

Companion post: LeWorldModel: One Regularizer Instead of Six for Pixel JEPA.

Handlebars is a modern and extensible templating solution originally created in the JavaScript world. It’s used by many popular frameworks like Ember.js and Chaplin. It’s also ported to some other platforms such as Java.

Handlebars is a template rendering engine but lacks extensive filters and transformers for context data during rendering. Like many such libraries, Handlebars allows you to create custom operations, called 'helpers'.

Here I will write an instruction set on how to write custom helpers for handlebars-rust.

use handlebars::{Handlebars, RenderError, HelperDef, RenderContext, Helper, Context, handlebars_helper};
use serde_json::Value as Json;

// #[allow(non_camel_case_types)]
// pub struct is_defined;

// impl HelperDef for is_defined {
//     fn call_inner<'reg: 'rc, 'rc>(
//         &self,
//         h: &Helper<'reg, 'rc>,

def getvalue(value, path, default=None):
    """Get a named attribute or item from an object; getvalue(x, 'y.z')
       is equivalent to x.y.z
    When a default argument is given, it is returned when the attribute doesn't
    exist; without it, None returned
    List indexing supported x.0.y.1.z etc.

# Script to remove GPG user (recipient) with git-crypt

# It will re-initialize git-crypt for the repository and re-add all keys except
# the one requested for removal.
#
# Note: You still need to change all your secrets to fully protect yourself.
# Removing a user will prevent them from reading future changes but they will
# still have a copy of the data up to the point of their removal.
