title: naive bayes accuracy increasing as increasing in the alpha value
body: <p>I'm using naive Bayes for text classification and I have 100k records in which 88k are positive class records and 12krecords are negative class records. I converted sentences to unigrams and bigrams using countvectorizer and I took alpha range from [0,10] with 50 values and I draw the plot. <a href="https://i.stack.imgur.com/Y2Stz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Y2Stz.png" alt="enter image description here"></a></p>
  
  <p>In Laplace additive smoothing, If I keep increasing the alpha value then accuracy on the cross-validation dataset also increasing. My question is is this trend expected or not?</p>
