One of the most common uses of Machine Learning today is in the domain of Robotics. Robotic tasks include a multitude of ML methods tailored towards navigation, robotic control and a number of other tasks. Robotic control includes controlling the actuators available to the robotic system. An example of this is control of a painting arm in automotive industries. The robotic arm must be able to paint every corner in the automotive parts while minimizing the quantity of paint wasted in the process. Which of the following learning paradigms would you select for training such a robotic arm?
A) Supervised learning
B) Unsupervised learning
C) Combination of supervised and unsupervised learning

Answer 1

As per u r question, my answer is C

Answer 2

Answer the questions by choosing the correct option.

Explanation:

• (1)Supervised learning is an implementation approach to Artificial Intelligence. It is used to make predictions and sense out of the given data.
• Hence, all of the given problems are supervised learning problems. The answer is option (d).
• (2)Classification tasks include classifying the data based on given information.
• Hence, finding gender from writing style is a way of classifying the data into gender based on the information regarding their writing style. The answer is option (a).
• (3) The mother tongue of a person is a categorical feature as it can belong to either of the languages which here is the category the data can be assigned to.
• Hence, the answer is option(c).
• (5) Occam's razor is a problem-solving theory and it uses a  hypothetical razor tool to remove improbable options in a given scenario.
• Hence, we know that it is an inductive bias. The answer is option (a)
• (6) As the size of the training set keeps on increasing the generalization performance starts improving consecutively. The answer is option (a).
• (7) For implementing such type of robotic arm the Reinforcement learning paradigm should be implemented.
