Dear Group,
To improve my code writing I am trying to read good codes. Now, I have received
a code,as given below,(apology for slight indentation errors) the code is
running well.
Now to comprehend the code, I am looking to understand it completely.
class Calculate:
def __init__(self):
self.prior = {}
self.total = {}
self.count = 0
def add(self, cls, obs):
self.prior[cls] = self.prior.get(cls, 0) + 1
for idx, val in enumerate(obs):
key = cls, idx, val
self.total[key] = self.total.get(key, 0) + 1
self.count += 1
def discr(self, cls, obs):
result = self.prior[cls]/self.count
for idx, val in enumerate(obs):
freq = self.total.get((cls, idx, val), 0)
result *= freq/self.prior[cls]
return result
def classify(self, obs):
candidates = [(self.discr(c, obs), c) for c in self.prior]
return max(candidates)[1]
I am not understanding many parts of it, I am understanding many parts of it
also.
So I am looking for an exercise what are the things I should know to understand
it, (please do not give answers I would get back with the answers in a week and
would discuss even how to write better than this).
If any one of the expert members of the room kindly help me to do this.
Thanking You in Advance,
Regards,
Subhabrata.
