How to Classify Protein-Protein interaction
Protein-protein interaction refers to the biological functions
carried out by the proteins within the cell by interacting with
other proteins in other cells as a result of biochemical events
and/or electrostatic forces. Such interactions are believed to
be important in understanding disease pathogenesis and de-
veloping new therapeutic approaches. A number of different
perspectives have been used to study these interactions rang-
ing from biochemistry, quantum chemistry, molecular dynam-
ics, signal transduction, among others78 All this information
enables the creation of large protein interaction databases.

Computer scientists Dilpreet and Singh 79 apply Jordan
neural networks to classify protein-protein interactions. The
sample used in their analysis was derived from three existing
databases80. It contained 753 positive patterns and 656 neg-
ative patterns81. Using amino acid composition of proteins as
input to the Jordan network to classify the percentage of in-
teracting and non-interacting proteins the researchers report a
classification accuracy of 97.25%.

Deep Learning to Woo Spanish Speakers
Neural networks have been successfully applied to the difficult
problem of speech recognition in English82. Accurate classi-
fication of the numerical digits 0 through 9 in Spanish using
Jordan neural networks was investigated by researcher Tellez

In a rather small study, the speech of the ten numerical
digits was recorded with voices from three women and three
men. Each person was requested to repeat each digit four times.
The network was then trained to classify the digits. Using nine
random initializations’ Tellez reports an average classification
accuracy of 96.1%.

Essential Elements for Effective Jor-
dan Models in R

I grew up in the heart of England where the weather is alwayson the move. If you want to experience all four seasons inone day, central England is the place to visit! Anyway, in
England, the weather is always a great conversation starter. So
let’s start our exploration of Jordan networks modeling British
weather. To be specific, we will model the temperature of the
city of Nottingham located in Nottinghamshire, England. You
may recall this area was the hunting ground of the people’s
bandit Robin Hood84. Let’s get our hands dirty and build a
Jordan neural network right now! As with Elman networks,
Jordan networks are great for modeling timeseries data.

Which are the Appropriate Packages?
We will use the RSNNS package along with the quantmod pack-
age. The data frame nottem, in the datasets package, con-
tains monthly measurements on the average air temperature
at Nottingham Castle85, a location Robin Hood would have
known well:
> require(RSNNS)
> data("nottem",package="datasets")
> require(quantmod)

Let’s take a quick peek at the data held in nottem:
