INTRODUCTION

For our Introduction to Artificial Intelligence project we have developed an Automated

Dietitian. A dietitians job is to guide people in eating the right food. The diet plays a vital part in

the physical well being of a person.


2/27

IDENTIFICATION

Automated dietician is an expert system that will give a specific diet depending on a

persons body mass index (BMI). The kiosk of this system will be set up in gyms and hospitals.

As diets are important part of keeping healthy and fitness many people who dont have the time

to go make an appointment with a dietician can use the system free of cost at their gym or at their

hospital.

People would want to use the system because they dont have to wait in long queues to

consult a dietician or make appointments and would have to pay no consultation fee. People can

use it in their regular visits to the hospital or the gym.

BENEFITS OF AUTOMATED DIETICIAN

1. Time saving.2. Easily accessible for the user.3. Free of cost.4. Can be used regularly and more frequently.5. Is available 24/7.

Minimal expenses have to be made for the setting of Kiosk. It will not require much space and

can be placed in small areas. It can be implemented in small clinics who cannot afford a

specialist in diets.

ANALYSIS OF PROBLEM DOMAIN

For analysing the problem domain we took into account the problems faced by the patients and

people who might have a weight problem and conducted an interview with a professional

dietician.

One talking to patients an people who visit the gym we found that the all their problems revolved

around time and costs.

Problem 1:

People dont have the time to make regular visits to the dietician for them to get regular updates

on their Body to Mass ratio, and the best diet.

Problem 2:

Every time a person visits a dietician he or she has to pay a consultancy fee, which turns out to

be very expensive.

Problem 3:

Many people are not even aware of the role of having a good diet plays on your health.

Problem 4:

People usually take it easy and feel its not important for them to visit a dietician as they think its

not worth the effort, when nothing is wrong.


5/27

EXPERT INTERVIEW

An interview with a an expert on nutrition and diets was conducted for identifying the domain

problem and also for knowledge acquisition, which will be discussed later in the documentation.

We asked the dietician questions around what he sees as the main problems faced by dieticians

and what could help him to provide better service to the people and would a system like this help

people on keeping healthy.

On conducting the interview our main findings were

1. The main problem the dietician faces is time; the dietician doesnt have enough time tofor every patient, as he is packed with appointments throughout the day. This sometimes

might lead to a misdiagnosis or the dietician might miss out on something

2. People get a little uncomfortable when asked about their personal habits and lives.3. Most people are very conscious about their weight.4. Some people might be embarrassed to share these problems.5. One of the biggest problems expressed by the dietician is that people are mostly ignorant

about what they eat, and might not think they have a problem. People feel that going to a

dietician is a waste of time if you are not fat or overweight.

6. The Dietician felt that a system like this might be very useful as people would feel morecomfortable as no one will be judging them

7. He also expressed the importance of keeping a regular check on your diet.

7/27

The Virtual Dietician has a very limited knowledge base. It can only respond to choices made by

the users and take around those areas.

We have taken into account the merits and demerits of both these system and attempted to

incorporate it in our system. Our system will be:

Quick in giving advice diets Will give a full diet. It will be able to check for special cases, like deities or hypertension or allergies.

Knowledge Acquisition

Strategy

Our Knowledge Acquisition was done mainly on four fronts

i. Field visitsii. Searching the internetiii. Library visitsiv. Expert opinion

1. Field Visits

We visited few gyms and hospitals to talk to the people about their diets, and conducted

survey and handed out simple questionnaires about what people felt about visiting a

nutritionist or a dietician. We also took this opportunity to interview a few people.

Talking with the people

On talking to the people in gyms and people visiting hospitals we learnt that people dont have

the time to visit a nutritionist as often as they would like to. They supported the idea of having a

fast and easy way to get a healthy diet.

While dealing with the general public we did not face those many problems. People were

generally supportive and enthusiastic. This was mostly because it dealt with the health and well

being of the people and when it comes to ones well being people are usually very supportive.

2. Internet researchWith the help of the world wide web we were able to acquire knowledge about the

different types of diets for different conditions, like people who are underweight or


14/27

overweight. A lot of the information was derived from this source. Most of the diets were

found on the internet.

There was a lot of information available on the net. We had a problem choosing which

was the best out of the lot and which was the most genuine.

3. Library visitsThe library visits were not very helpful as it is difficult to find information for such topics

in a business school.

We faced problems in acquiring knowledge from library sources as there were limited

options on the subject.

4. Experts Opinion

Dealing with the experts was the toughest part of knowledge acquisition. We felt a bit of

hostility and general lack of support from them. This was because they didnt want to

help create something that is being made with the scope to replace them. Despite this we

were able to find an open minded dietician who was open to the idea of a system

providing people diets and helping them keep healthy. Dr. Pandian, Medical Registrar of

ADK hospital, Maldives, was kind enough to provide his assistance. We were able to

formulate an ideal diet with his help.

He also helped us in giving us an insight of the mentality of the people who visit a

dietician and the different aspects involved in being a dietician. He gave us a list of

frequently asked questions by the patience which was very helpful in creating our

knowledge base.

For Example:


15/27

Which meal should be your largest?

What foods can help you grow?

What is the best way to lose weight?

What food is essential in a persons deit

As Dr. Pandian is set up in Maldives we had problems setting up proper interviews and

communicating with him on regular bases. We were able to work around this by

conducting video conferencing and keeping in touch via email.


16/27

Evaluation of Prototype

Expert opinion

As our expert wasnt available we were not able to give him a working prototype of our

system. To our best we explained to him how it would work and what it would do.

According to Dr. Pandian when it comes to medicine and AI, a computer could never

fully replace a human doctor as it would lack the basic sense and would lack the ability to

make assumption based on factors that might go unnoticed if a computer system is

diagnosing. A doctor has to make some assumptions based on the how a patient reacts.

Sometimes patients tend to hide information from doctors.

On the other hand he supported the idea of a system that might give a very simple

diagnosis or in our case a simple diet.

With respect to our system he had made a few suggestions.

a) The system should not demine anyone or be insulting in anyways as it deals witha sensitive topic.

b) System should take into account the users medical history, i.e. if he or she isallergic to any food or has diabetes or hyper tension

c) It should be able to hold a large knowledge based) What are the best foods to eat before and after a workout?e)

Performance/Achievement

The system runs smoothly and is able to produce diets for the chosen condition. Still there is a lot

of scope for improvement. There were some problems at first. Verbot was not able to comply.


17/27

Loading the data base takes longer than expected because of the size of the knowledge base.

Other than that there are some minor unrecognisable twitches.

Once the system loads it is able to run smoothly. All the calculations are swift and it is quick to

respond to the user.

Future Development

There is tremendous scope for improvement in the system. Due to time constrains we couldnt

make our knowledge base as strong and complete as we would have wanted to. More conditions

could have been added, for example making specific meals for allergies. Responding to more

queries the user might have. Nutrition advice is a very vast subject and it would take a lot of time

and effort for someone to create a complete dietician system.


18/27

Conclusion

Automated Dietician could be a big success if more time is given for development.

People could be made more aware of what they eat and what effect it has on their body

and health. With fast food and junk food being the most popular type of food today, a

system such as ours is direly needed to keep in check the health of the people. Most

people are under the misconception that if you are not overweight you are healthy. Being

health is very different from being thin. A good diet with the right amount of nutrients is

needed to keep the body healthy.

If given the time and resources the Automated Dietician would be able to

a. Help anyone with any medical condition to make a diet planb. Eliminate the need of going to a dieticianc. Provide scheduled check-up routines
