Are we sure that exponentiating will give us the probabilities? I did some tests by cloning the MLLIb class and adding the required code but the calculated probabilities do not add up to 1.
I tried something like : def predictProbs(testData: Vector): (BDV[Double], BDV[Double]) = { val logProbs = brzPi + brzTheta * new BDV[Double](testData.toArray) val probs = logProbs.map(x => math.exp(x)) (logProbs, probs) } This was because I need the actual probs to process downstream from this... -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/MLlib-Naive-Bayes-classifier-confidence-tp18456p20175.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
