solutions passed
What is machine learning? (Murphy) - ANS ✔We define machine learning as a set of methods
that can automatically detect patterns in data, and then use the uncovered patterns to predict
future data, or to perform other kinds of decision making under certainty.
What is machine learning? (Wiki) - ANS ✔Machine learning (ML) is a field of study in artificial
intelligence concerned with the development and study of statistical algorithms that can learn
from data and generalize to unseen data and thus perform tasks without explicit instructions.
What are the classes of machine learning? - ANS ✔Supervised, Unsupervised, and
Reinforcement learning.
Supervised learning - ANS ✔Supervised learning is the class of machine learning where the goal
is to learn a function that maps an input to an output based on example input-output pairs
(labelled data).
Unsupervised learning - ANS ✔Machine learning task of inferring a function that describes the
structure of unlabeled data (data that has not yet been classified or categorized)
Reinforcement learning - ANS ✔Area of ML concerned with how intelligent agents ought to take
actions in a dynamic environment in order toe maximize the notion of cumulative reward.
What is data in ML? - ANS ✔Data refers to the collection of raw information, observations, or
measurements that are used to train and evaluate models.
1) Numeric measurements (binary, int, float, etc)
2) Text (characters, words, strings, docs)
