Algoritmo C# para dendrograma VI (Datos)

Los datos para hacer pruebas los he sacado de un repositorio público de datos de la UCI: http://archive.ics.uci.edu/ml/ por mediación de la UOC: http://www.uoc.edu para hacer la práctica.

Descripción de los datos:
Title: Acute Inflammations

Abstract: The data was created by a medical expert as a data set to test
the expert system, which will perform the presumptive diagnosis of two
diseases of the urinary system.

Data Set Information:

The main idea of this data set is to prepare the algorithm of the expert
system, which will perform the presumptive diagnosis of two diseases of
urinary system. It will be the example of diagnosing of the acute
inflammations of urinary bladder and acute nephritises. For better
understanding of the problem let us consider definitions of both
diseases given by medics. Acute inflammation of urinary bladder is
characterised by sudden occurrence of pains in the abdomen region and
the urination in form of constant urine pushing, micturition pains and
sometimes lack of urine keeping. Temperature of the body is rising,
however most often not above 38C. The excreted urine is turbid and
sometimes bloody. At proper treatment, symptoms decay usually within
several days. However, there is inclination to returns. At persons with
acute inflammation of urinary bladder, we should expect that the illness
will turn into protracted form.

Acute nephritis of renal pelvis origin occurs considerably more often at
women than at men. It begins with sudden fever, which reaches, and
sometimes exceeds 40C. The fever is accompanied by shivers and one- or
both-side lumbar pains, which are sometimes very strong. Symptoms of
acute inflammation of urinary bladder appear very often. Quite not
infrequently there are nausea and vomiting and spread pains of whole
abdomen.

The data was created by a medical expert as a data set to test the
expert system, which will perform the presumptive diagnosis of two
diseases of urinary system. The basis for rules detection was Rough Sets
Theory. Each instance represents an potential patient.

The data is in an ASCII file. Attributes are separated by TAB. Each line
of the data file starts with a digit which tells the temperature of patient.

-- Attribute lines:
For example, '35,9 no no yes yes yes yes no'
Where:
'35,9' Temperature of patient
'no' Occurrence of nausea
'no' Lumbar pain
'yes' Urine pushing (continuous need for urination)
'yes' Micturition pains
'yes' Burning of urethra, itch, swelling of urethra outlet
'yes' decision: Inflammation of urinary bladder
'no' decision: Nephritis of renal pelvis origin

----------------------------------------------------------------------------

Attribute Information:

a1 Temperature of patient { 35C-42C }
a2 Occurrence of nausea { yes, no }
a3 Lumbar pain { yes, no }
a4 Urine pushing (continuous need for urination) { yes, no }
a5 Micturition pains { yes, no }
a6 Burning of urethra, itch, swelling of urethra outlet { yes, no }
d1 decision: Inflammation of urinary bladder { yes, no }
d2 decision: Nephritis of renal pelvis origin { yes, no }

Hi! I need some help and I hope you can give me some advices.
I want to write some c# code that allows me to plot a dendrogram, giving as input a matrix of euclidean distances.
Actually I can't find anything on the net that can be useful. The only interesting things are some tools (to pay)..
Thank you
Paolo

Hi paolo, posts named "Algoritmo C# para dendrograma" have useful C# code for you. If you need more information you can write via email.
