Summary: Bristol implements techniques developed by Mezzadri with parallel processing capabilities and a data model for further processing for generating random matrices. Circular module provides methods to generate matrices from Circular Unitary Ensemble (CUE), Circular Ortogonal Ensemble (COE) and Circular Symplectic Ensemble (CSE). Additional spectral analysis utilities are also implemented, such as computation of spectral density and spectral ergodicity for complexity of deep learning architectures.

        Parallel random matrix tools and complexity for deep learning
        
        Bristol implements techniques developed by Mezzadri with parallel processing capabilities and a data model for further processing for generating random matrices. Circular module provides methods to generate matrices from Circular Unitary Ensemble (CUE), Circular Ortogonal Ensemble (COE) and Circular Symplectic Ensemble (CSE). Additional spectral analysis utilities are also implemented, such as computation of spectral density and spectral ergodicity for complexity of deep learning architectures.
        
        ## Features
        
        * Generation of Circular Ensembles: CUE, COE and CSE.
        * Random matrices: Reproducibility both in serial and parallel processing.
        * Eigenvalue Spectra, spectral densitiy.
        * Kullbach-Leibler divergence and spectral ergodicity measure functionality.
        * Cascading Periodic Spectral Ergodicity (cPSE)
        
        ## Installation
        
        Install with pip from [pypi](https://pypi.python.org/pypi/bristol).
        
        ```bash
        pip install bristol
        ```
        
        To use the latest development version
        
        ```bash
        pip install -upgrade git+https://github.com/msuzen/bristol.git
        ```
        
        ## Documentation
        ### Complexity of a deep learning model: cPSE
        
        You need to put your model as pretrained model format of PyTorch. An example for vgg, 
        and use `cPSE.cpse_measure` function simply:
        
        ```
        from bristol import cPSE
        import torchvision.models as models
        netname = 'vgg11'
        pmodel = getattr(models, netname)(pretrained=True)
        (d_layers, cpse) = cPSE.cpse_measure(pmodel)
        ```
        
        This would give `cpse` a single number expressing the complexity of your network and `d_layers` evolution of 
        `periodic spectral ergodicity` withing layers as a vector, order matters.
