        # clana
        
        `clana` is a toolkit for classifier analysis. One key contribution of clana is
        Confusion Matrix Ordering (CMO) as explained in chapter 5 of [Analysis and Optimization of Convolutional Neural Network Architectures](https://arxiv.org/abs/1707.09725). It is a technique
        that can be applied to any multi-class classifier and helps to understand which
        groups of classes are most similar.
        
        
        ## Installation
        
        The recommended way to install clana is:
        
        ```
        $ pip install clana --user
        ```
        
        If you want the latest version:
        
        ```
        $ git clone https://github.com/MartinThoma/clana.git; cd clana
        $ pip install -e . --user
        ```
        
        ## Usage
        
        ```
        $ clana --help
        Usage: clana [OPTIONS] COMMAND [ARGS]...
        
        Options:
          --version  Show the version and exit.
          --help     Show this message and exit.
        
        Commands:
          distribution   Get the distribution of classes in a dataset.
          get-cm         Calculate the confusion matrix (CSV inputs).
          get-cm-simple  Calculate the confusion matrix (one label per...
          visualize      Optimize confusion matrix.
        ```
        
        The visualize command gives you images like this:

        ### MNIST example
        
        ```
        $ cd docs/
        $ python mnist_example.py  # creates `train-pred.csv` and `test-pred.csv`
        $ clana get-cm --gt gt-train.csv  --predictions train-pred.csv --n 10

        This gives

        #### Label Manipulation
        
        Prepare a `labels.csv` which **has to have a header row**:
        
        ```
        $ clana visualize --cm cm.json --zero_diagonal --labels mnist/labels.csv
        ```
        
        ![](mnist_confusion_matrix_labels.png)
        
        
        ### Data distribution
        
        ```
        $ clana distribution --gt gt.csv --labels labels.csv [--out out/] [--long]
        ```
        
        prints one line per label, e.g.
        
        ```
        60% cat (56789 elements)
        20% dog (12345 elements)
         5% mouse (1337 elements)
         1% tux (314 elements)
        ```
        
        If `--out` is specified, it creates a horizontal bar chart. The first bar is
        the most common class, the second bar is the second most common class, ...
        
        It uses the short labels, except `--long` is added to the command.
        
        
        ### Metrics
        
        ```
        $ clana metrics --gt gt.csv --preds preds.csv
        ```
        
        gives the following metrics by
        
        * Line 1: Accuracy
        * Line 2: Precision
        * Line 3: Recall
        * Line 4: F1-Score
        * Line 5: Mean accuracy
