More projects
Radient
- Rust library for automatic differentiation using computational graphs
- Implements forward and backward propagation for gradient computation
- Supports various mathematical operations, including exponential, logarithmic, power, and trigonometric functions
- Provides two options for gradient calculation:
-
gradient: Concise but relatively slower -
gradient_cached: Fast but slightly more verbose
-
- Includes examples demonstrating basic operations with symbols, gradient calculation, and a single-layer perceptron implementation
DeeLeMa
- Deep learning network for estimating mass and momenta in particle collisions at high-energy colliders
- Generates robust mass distributions with peaks at physical masses, even with combinatoric uncertainties and detector smearing effects
- Adaptable to different event topologies, particularly effective when corresponding kinematic symmetries are adopted
- Current version (v1.0.0) is constructed on the
$t\bar{t}$ -like antler event topology - Provides clear instructions for installation, training, and monitoring using Pip or Huak (recommended)
- Encourages citation of the associated research paper if DeeLeMa benefits users' research
