0.3.0
Added:
- Support for hybrid quantum-classical models using the
PennyLaneModel
.PennyLane
is a powerful QML library that allows the development of hybrid ML models by hooking numerically determined gradients of parametrised quantum circuits (PQCs) to the autograd modules of ML libraries like PyTorch or TensorFlow. - Add lambeq-native loss functions
LossFunction
to be used in conjunction with theQuantumTrainer
. Currently, we support theCrossEntropyLoss
,BinaryCrossEntropyLoss
, and theMSELoss
loss functions. - Python 3.11 support.
- An extensive NLP-101 tutorial, covering basic definitions, text preprocessing, tokenisation, handling of unknown words, machine learning best practices, text classification, and other concepts.
Changed:
- Improve tensor initialisation in the
PytorchModel
. This enables the training of larger models as all parameters are initialised such that the expected L2 norm of all output vectors is approximately 1. We use a symmetric uniform distribution where the range depends on the output dimension (flow) of each box. - Improve the fail-safety of the
BobcatParser
model download method by adding hash checks and atomic transactions. - Use type union expression
|
instead ofUnion
in type hints. - Use
raise from
syntax for better exception handling. - Update the requirements for the documentation.
Fixed:
- Fixed bug in
SPSAOptimizer
triggered by the usage of masked arrays. - Fixed test for
NumpyModel
that was failing due to a change in the behaviour of Jax. - Fixed brittle quote-wrapped strings in error messages.
- Fixed 400 response code during Bobcat model download.
- Fixed bug where
CircuitAnsatz
would add empty discards and postselections to the circuit.
Removed:
- Removed install script due to deprecation.
