Warning

Since 0.3.x, we have reorganized the package structure. Any upper app should be revised accordingly.
Since 1.0.0, we stopped pyCLAMs and switch to cla.

Installation

pip install cla (pyCLAMs for versions under 1.0.0)
pip install rpy2
Install the R runtime and the ECol library (https://github.com/lpfgarcia/ECoL).

Run 'install.packages("ECoL")' in R. It will take very long time. You must wait for the installation to complete.
Sometimes, you may want to change the CRAN mirror. Under the "Packages" menu, click "Set CRAN Mirror".
After installation, you can check by R command 'installed.packages()'.

How to use

Download the sample dataset from the /data folder Use the following sample code to use the package:

  # import clams # (for versions < 1.0.0)  
  from cla import metrics # (for versions > 1.0.0)  

  # load the dataset or generate a toy dataset by X,y = mvg(md = 2)
  df = pd.read_csv('sample.csv')
  X = np.array(df.iloc[:,:-1]) # skip first and last cols
  y = np.array(df.iloc[:,-1])

  # get all metrics
  metrics.get_metrics(X,y) # Return a dictionary of all metrics

  # get metrics as JSON
  metrics.get_json(X,y)

  # get an html report and display in Jupyter notebook
  from IPython.display import display, HTML
  display(HTML(metrics.get_html(X,y)))

Start the web GUI

1. python -m cla.gui.run
2. Open http://localhost:5005/ in your browser.

3. A ready-to-use online demo is http://spacs.brahma.pub/research/CLA

Metrics and functions added since the original publication

1. metrics

classification.Mean_KLD - mean KLD (Kullback-Leibler divergence) between ground truth and predicted one-hot encodings
correlation.r2 - R2, the R-squared effect size
test.CHISQ, test.CHISQ.log10, test.CHISQ.CHI2 - Chi-squared test
classification.McNemar, classification.McNemar.CHI2 - McNemar test on the groud-truth and classifier's prediction
classification.SVM.Margin - the linear-SVC's margin width
test.student, test.student.min, test.student.min.log10, test.student.T, test.student.T.max
test.KW, test.KW.min, test.KW.min.log10, test.KW.H, test.KW.H.max
test.Median, test.Median.min, test.Median.min.log10, test.Median.CHI2, test.Median.CHI2.max

2. refactor

Integrate some existing packages and reorganize the package structure.
