qlabs-eng / noise

Speedrun for pretraining without backpropagation

qlabs-eng / dust

Pretraining Transformers Without Backpropagation

HIPS / autograd

Efficiently computes derivatives of NumPy code.

shashwatak / satellite-js

Modular set of functions for SGP4 and SDP4 propagation of TLE and OMM.

gprMax / gprMax

gprMax is open source software that simulates electromagnetic wave propagation using the Finite-Difference Time-Domain Finite-Difference (FDTD) code for numerical modelling of Ground Penetrating Radar (GPR), antennas, radar and bioelectromagnetics

JuliaPhysics / Measurements.jl

Error propagation calculator and library for physical measurements. It supports real and complex numbers with uncertainty, arbitrary precision calculations, operations with arrays, and numerical integration.

SPECFEM / specfem3d

SPECFEM3D Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, or poroelastic seismic wave propagation in any type of conforming mesh of hexahedra (structured & unstructured).

tstanczyk95 / McBytePlusPlus

McByte++ : faster, enhanced and long-term tracking version of McByte. With re-ID included.

Wrste / pheromone-network

A zero-dependency TypeScript memory kernel that gives any agent long-term memory. No training or backpropagation: each output reads a few tag-compatible neighbors, updated by a manual Hebbian rule. Links used often are reinforced; idle ones evaporate by half-life. Based on the paper Local Pheromone Network (arXiv:2606.30669).

hewanglanhao / deepvision-studio

Interactive deep learning lab for visualizing forward/backpropagation, training real PyTorch models, and exploring CNNs, Transformers, RNNs, and AI history.

agentscope-ai-java / interp-rpc

Typed RPC over a warm pool of PEP 734 subinterpreters — real parallelism, real error propagation, no hanging calls.

dev-luigi / neural-network-digits

Neural network from scratch in pure Python + NumPy that recognises handwritten digits (MNIST), with an educational GUI: watch it learn, tweak it while it trains, look inside every layer.

tooladda-online / dns-propagation-checker

DNS Propagation Checker — Check whether a DNS change has propagated by querying four independently operated public DNS resolvers — Google, Cloudflare, DNS.SB, and RethinkDNS — live and in parallel. Get a consensus score, per-resolver TTL and response time, DNSSEC status, and optional exact-value matching against the change you made. Free on Tool...
