Self-Test 1 Dependent Features:

P(cold) = priori probability of a person having a cold is 40%

P(fever) = priori probability of a person having a fever is 20%

P(cold & fever) = known to be 10%

P(cold | fever) = =

Self-Test 2:

• Let's assume you can compute P(any word) for police arrest records after going through the training corpus. What other conditional probabilities can you compute based on these?
  • Give specific P(word1|word2)'s you want to find out. **
  • How will that help us??**
