Python logsumexp Examples

Example #1

File: testutil.py Project: datamicroscopes/common

def scores_to_probs(scores):
    scores = np.array(scores)
    scores -= logsumexp(scores)
    scores = np.exp(scores)
    return scores

Example #2

File: test_models_mixture_dp.py Project: jzf2101/mixturemodel

 def score_post_pred(y):
     # XXX: the C++ API can only handle structural arrays for now
     y = np.array([y], dtype=[('', bool)] * D)[0]
     _, scores = s.score_value(y, r)
     return logsumexp(scores)

Example #3

 def score_post_pred(y):
     # XXX: the C++ API can only handle structural arrays for now
     y = np.array([y], dtype=[('', bool)] * D)[0]
     _, scores = s.score_value(y, r)
     return logsumexp(scores)

Example #4
