Write advantages of Artificial Neural Networks. (3 Marks)
Ans:
Advantages of Artificial Neural Networks:
Excellent for pattern recognition
Excellent classifiers
Handles noisy data well
Good for generalization
Write disadvantages of Artificial Neural Networks. (5 Marks)
Ans:
1. parallel architecture:
• The power of Artificial Neural Networks is lie in their parallel architecture ,most machines
are serial (Von Neumann architecture)
2. defined rules:
• Lack of defined rules to build a neural network for a specific problem as there are too many

layers, data representation etc
3. Knowledge is implicit
4. Data dependency
What is machine learning? (2 marks)
Ans:
Machine learning is the ability of knowledge based systems to improve through experience. And is
divided into three categories..
Rote learning,
Inductive learning and
deductive learning.

what intelligence ability is better in living species than in computers. Why it is better? (2.5 + 0.5 = 3
marks)
computers are better than people are at remembering things exactly and at performing complex
numeric calculations with speed. But human brains still beat computers in a number of ways. For one,
humans can integrate information from many different variables and stimuli, and they can learn by
experience, observation and experimentation. Computers can't easily adapt to changing situations.
Sure, they can be programmed to perform outstandingly in a particular field, but they are not able to
function in multiple disciplines. Moreover, the things that make humans truly unique (emotion,
empathy, self-awareness, ambition) are beyond the capacity of computers.
what term is used to describe the relationship between input and output? (2 marks)
discuss ID3 in decision tree representaion(5marks) ID stands for interactive dichotomizer.The first step of ID3 is to find the root node. It uses a special
function GAIN, to evaluate the gain information of each attribute. For example if there are 3
instances, it will calculate the gain information for each. Whichever attribute has the maximum gain
information, becomes the root node. The rest of the attributes then fight for the next slots.

Initialize plan ‘p’ with initial_state linked to goal state with two special actions, start and finish Loop until there is not unsatisfied pre-condition Find an action ‘a’ which satisfies an unachieved pre-condition of some action ‘b’ in the plan Insert ‘a’ in plan linked with ‘b’ Reorder actions to resolve any threats End In POP algorithm pre-conditions of finish action are not met. We just backtrack by adding actions that meet these unsatisfied pre-condition predicates. New unsatisfied preconditions will be generated for each newly added action. Then we try to satisfy those by using appropriate actions. we keep on doing that until there is no unsatisfied precondition. linear model,s phases any 5(3 marks) The main phases of the linear sequence are Planning Knowledge acquisition and analysis Knowledge design Code Knowledge verification System evaluation what is robotics?write the name of different active areas involved in robotics?(3 marks) Robotics: Robotics is the highly advanced and totally hyped field of today. Literally Speaking, robotics is the study of robots. Robots are complex combination of hardware and intelligence, or mechanics and brains. Active areas involved in robotics: robotics is truly a multi-disciplinary area, having active contributions from, physics, mechanics, biology, mathematics, computer science, statistics, control thory, philosophy, etc. Differentiate find s and candidate elimination algorithms (2marks)

the output fuzzy set.
The consequent of a fuzzy rule assigns an entire fuzzy set to the output.
This fuzzy set is represented by a membership function that is chosen to indicate the qualities of the
consequent.
Come and Join Us at www.vustudents.ning.com
If the antecedent is only partially true, i.e., is assigned a value less than 1, then the output
fuzzy set is truncated according to the implication method.
One rule is usually not enough so 2-3 rule implemented by it. The output of each rule is a fuzzy set.
The output fuzzy sets for each rule are then aggregated into a single output fuzzy set. Finally the
resulting set is defuzzified, or resolved to a single number
2) find the entropy of S lec #38 first example (5Mrks)
3) how working memory is related to the Expert System? (2Marks)
working memory contains the problem facts that are discovered during the session’ according to
Durkin. One session in the working memory corresponds to one consultation.
4) what is the basic task of clustering (3 marks)
The basic task of clustering is to identify and group similar individual data elements based on some
measure of similarity. So basically using clustering algorithms, classification information can be
produced from a training data
5)why we need hypothesis space (2 marks)
all problem discuss in the Ai are real world example/cases where concept space consists of larger
number of attributes.So the learner has to apply some hypothesis, which has either a search or the
language bias to reduce the size of the concept space. This reduced concept space becomes
the hypothesis space.
7) what do you know about Mandani's fuzzy inference (3Marks)
Mamdani's fuzzy inference method is the most commonly seen fuzzy
methodology. It was among the first control systems built using
fuzzy set theory. Ebrahim Mamdani proposed it in 1975 by as an attempt to
control a steam engine and boiler combination by synthesizing a set of linguistic
control rules obtained from experienced human operators.
9)what is the consequent?
consequent is the component of rule and it make the conclusion or the THEN part of the RULE.

Q2) What is MSE? 2Marks
MSE is the most common technique for measuring the total error in each iteration of the neural
network.
Q3) How does the search paths don’t remain independent in Genetic algorithm? 2 Marks
In GA ,At each step, current states of different pairs of these paths are combined to form new
paths. This way the search paths don't remain independent, instead they share information
with each other and thus try to improve the overall performance of the complete search space.
Q4) Define Vision space? 2 Marks
Q5) What is State in Strips? Give an example. 2 Marks
STRIPS is one of the founding languages developed particularly for planning.and State is a
conjunction of predicates represented in well-known form,
Example,
a state where we are at the hotel and do not have either cash or radio is represented as,
at(hotel) ∧ ¬have(cash) ∧ ¬have(radio)
Q6) Breifly explain the different phases of machine learning? 3 Marks
1. Training: a training set of examples of correct behavior is analyzed and some representation
of the newly learnt knowledge is stored. This often defines form of rules.
2. Validation: the rules are checked and, if necessary, additional training is given. Sometimes
additional test data are used, but instead of using a human to validate the rules, some other
automatic knowledge based component may be used. The role of tester is often called the critic.
3. Application: the rules are used in responding to some new situations.

Q7) How problem solution constitute the problem solving? 3 Marks
in problem solving ,this should be known that what will be out ultimate aim. i.e, what should be the
output of our procedure in order to solve the problem.
For example in the case of mouse, the ultimate aim is to reach the cheese. The state of world when
mouse will be beside the cheese and probably eating it defines the aim. This state of world is
also referred to as the Goal State or the state that represents the solution of the problem.
Q8) Write down the name of the some of the fuzzy logic applications? 3 Marks

ü Planning phase of the linear model?
The planning phase of the linear model involves the following steps
Come and Join Us at www.vustudents.ning.com
Feasibility assessment
Resource allocation
Task phasing and scheduling
Requirements analysis
ü Explain Learning?
a relatively permanent change that occurs in behavior as a result of experience. Learning
occurs in various regimes. For example, it is possible to learn to open a lock as a
result of trial and error; possible to learn how to use a word processor as a result of following
particular instructions.
There’s no proper definition of learning but here are some as:
• "Learning denotes changes in a system that ... enables a system to do the
same task more efficiently the next time." --Herbert Simon
• "Learning is constructing or modifying representations of what is being
experienced." --Ryszard Michalski
• "Learning is making useful changes in our minds." --Marvin Minsky
ü Explain Planning?
Planning is an advanced form of problem solving which generates a sequence of operators
that guarantee the goal. Furthermore, such sequence of operators or actions is called a plan. it
is based on logic representation
ü What Is Information Gain?
Come and Join Us at www.vustudents.ning.com
Information gain is the expected reduction in entropy caused by partitioning the examples
according to its attribute. i.e, if we use the attribute with the maximum information gain as the
node, then it will classify some of the instances as positive or negative with 100% accuracy,
and this will reduce the entropy for the remaining instances.
ü 2 main functions of brain in human system?
Introspection: that is trying to catch out own thoughts as they go by.
Psychological Experiments: that concern with the study of science of
mental life.
ü Why clustering is the example of unsupervised ?
in Unsupervised learning The data have no target attribute.We want to explore the data to find some
intrinsic structures in them. Clustering is often called an unsupervised learning task as no class
values denoting an a prior grouping of the data instances are given, which is the case in supervised
learning. there is no supervision of classification in clustering algorithms for their
learning/clustering, and hence they fall under the category of unsupervised learning.
ü Application of the fuzzy operators to antecedent?
Antecedents can have multiple parts:
• If wind is mild and racquets are good then playing badminton is fun In this case all parts of
the antecedent are resolved simultaneously and resolved to a single number using logical
operators
ü Machine Learning in Expert system? 5 marks
The primary application of machine learning inexpert systems is to attempt to solve
theknowledge acquisition bottleneck. Mostly Inductive and deductive learning phases from
machine learning took part in expert system. The job of the learning algorithm is to find
Come and Join Us at www.vustudents.ning.com
suitable rules that are correct with respect to the examples and existing knowledge.
inductive learning is based on the knowledge that if something happens a lot it is likely to be
generally true.while Deductive learning working on existing facts and knowledge and
deduces new knowledge from the old. In contrast, inductive learning uses examples
and generates hypothesis based on the similarities between them.

3) Write the Predicate Action? Ans:
Action is a predicate used to change states. It has three components namely, the
predicate itself, the pre-condition, and post-condition predicates. For example,
the action to buy something item can be represented as,
Action:

vision, robotics, soft-computing
and clustering.
6) What is the Linear Separable line? Ans:
if we represent whole class of problems in the input space,

logical AND or OR.
7) Genetic algorithms are Geniality use for what? Ans:
GA is naturally applied in machine learning applications. For example
one usage of genetic-fuzzy system is of ‘searching’ for an acceptable fuzzy
Come and Join Us at www.vustudents.ning.com
system that conforms to the training data. In which, fuzzy sets and rules
combined, are encoded as individuals, and GA iterations refine the individuals i.e. fuzzy system, on the basis of their
fitness evaluations.
2 Questions are of 5 marks
1)Write the Find(s) algorithm.
Ans:
Initialize h to the most specific hypothesis in H
For each positive training instance x
For each attribute constraint ai in h
If the constraint ai is satisfied by x
Then do nothing
Else

constraint that is satisfied by x
Output hypothesis h
2)Discuss the POP Algorithms?
Ans:
POP(initial_state, goal, actions) returns plan
Begin
Initialize plan ‘p’ with initial_state linked to goal state with two
special actions, start and finish
Loop until there is not unsatisfied pre-condition
Come and Join Us at www.vustudents.ning.com
Find an action ‘a’ which satisfies an unachieved pre-condition of
some action ‘b’ in the plan
Insert ‘a’ in plan linked with ‘b’
Reorder actions to resolve any threats
End
What is planning?
Ans:
Planning is an advanced form problem solving which generates a sequence of
operators that guarantee the goal. Furthermore, such sequence of operators or
actions (commonly used in planning literature) is called a plan.
What is information gain?
Ans:
information gain, is simply the expected reduction in entropy caused by partitioning the examples according to this
attribute. That is, if we use the attribute with the maximum information gain
as the node, then it will classify some of the instances as positive or negative with
100% accuracy, and this will reduce the entropy for the remaining instances.
What is clustering ?
Ans:
Clustering is a form of unsupervised learning, in which the training data is
available but without the classification information or class labels. The task of
Come and Join Us at www.vustudents.ning.com
clustering is to identify and group similar individual data elements based on some
measure of similarity. So basically using clustering algorithms, classification
information can be ‘produced’ from a training data which has no classification
data at the first place. Naturally, there is no supervision of classification in
clustering algorithms for their learning/clustering, and hence they fall under the
category of unsupervised learning.
Define Defuzzing ?
Ans:
the aggregate of a fuzzy set encompasses a range of output values, and so must be defuzzified in order to
resolve a single output value from the set. The input for the defuzzification process is a fuzzy set (the aggregate
output fuzzy set) and the output is a single number. As much as fuzziness helps the rule
evaluation during the intermediate steps, the final desired output for each variable
is generally a single number.
Knowledge acquisition?
Ans:
This is the most important stage in the development of ES. During this stage the
knowledge engineer works with the domain expert to acquire, organize and
analyze the domain knowledge for the ES. ‘Knowledge acquisition is the
bottleneck in the construction of expert systems’ (Hayes-Roth et al.). The main
steps in this phase are
• Knowledge acquisition from expert
• Define knowledge acquisition strategy (consider various options)
• Identify concrete knowledge elements
• Group and classify knowledge. Develop hierarchical representation where
Come and Join Us at www.vustudents.ning.com
possible.
• Identify knowledge source, i.e. expert in the domain
Machine learning in developing expert systems?
Ans:
Many AI applications are built with rich domain knowledge and hence do not
make use of machine learning. To build such expert systems, it is critical to
capture knowledge from experts. However, the fundamental problem remains
unresolved, in the sense that things that are normally implicit inside the expert's
head must be made explicit. This is not always easy as the experts may find it
hard to say what rules they use to assess a situation but they can always tell you
what factors they take into account. This is where machine learning mechanism
could help. A machine learning program can take descriptions of situations
couched in terms of these factors and then infer rules that match expert's
behavior.
Concept learning
Two question of Connectionist?
Ans:
Although ID3 spanned more of the concept space, but still there is a possibility
that the true concept is not simply a mixture of disjunctions of conjunctions, but
some more complex arrangement of attributes.
(Artificial Neural Networks) ANNs can compute more complicated functions
ranging from linear to any higher order quadratic, especially for non-Boolean
concepts. This new learning paradigm takes its roots from biology inspired
Come and Join Us at www.vustudents.ning.com
approach to learning. Its primarily a network of parallel distributed computing in
which the focus of algorithms is on training rather than explicit programming.
Tasks for which connectionist approach is well suited include:
• Classification
• Fruits – Apple or orange
• Pattern Recognition
• Finger print, Face recognition
• Prediction
• Stock market analysis, weather forecast
Names of clustering Algorithm?
Ans:
The famous clustering algorithms are Self-organizing maps (SOM), k-means,
linear vector quantization, Density based data analysis, etc.
Artificial Neural Networks unsupervised step?
Ans:
Given a set of examples with no labeling, group them into
sets called clusters
Come and Join Us at www.vustudents.ning.com
How is the consequent affected by the antecedent?
Ans:
The consequent specifies
that a fuzzy set be assigned to the output. The implication function then
modifies that fuzzy set to the degree specified by the antecedent. The most
common ways to modify the output fuzzy set are truncation using the min function
(where the fuzzy set is "chopped off“).

(i) Clearly write your GA steps.
(ii) Identify the initial population, fitness function, mutation and crossover steps.
(iii) Can we find the solution word with only using crossover
operation? Support your answer with arguments?
Q#4
a) (5 marks) List and explain briefly the 5 steps of fuzzy inference.
b) (10 marks) Given the fuzzy system below, perform the inference graphically just like Matlab for input A=0 and B=100. Briefly explain the steps you followed and how the output value of variable Y is obtained in no more than 10 sentences. Clearly state any assumption that you take in the inference.
Q#5
Consider the graph showing a road map for distances between cities. The values on the edges are the distance between two adjacent cities. The values on the nodes are the under-estimates (heuristics) of the remaining distance. Construct a tree from the given graph and find the solution using the A* procedure considering A as the initial node, J as the destination node, and 12 as the bound value. Eliminate the bounded subtree(s) from your solutions and only show the resultant tree.

Question No: 24 (Marks: 10)
Discuss backward chaining with the help of doctor and patient example.
Answer:
Backward chaining:
Backward chaining is an inference strategy that works backward from a hypothesis to proof. Backward
chaining is like depth first strategy. In backward chaining all the terminology the hypothesis to prove is
called goal. It is start with the list of goals. Goals may be in working memory initially so check and you
are done if found if not then search for goal in the THEN part of the rules conclusion rather than
premises this type of rule are called Goal. Premises not listed become sub goals to prove. Process
continues in a recursive fashion until a premise is found that is not supported by a rule a premise is also
Come and Join Us at www.vustudents.ning.com
called primitive if it can not be conclude by any rule when a primitive is found ask user for information
about it back track and use this information to prove sub goals and subsequently the goal.
Backward chaining example:
Rule 1:
IF : A patient has deep cough
AND : We suspect an infection
THEN : The patient has phenomena
Rule: 2
IF : The patient’s temperature is above 100
THEN : Patient has fever
Rule 3:
IF : The patient has been sick fortnight
AND : The patient has fever
THEN : We suspect an infection
