Principal component analysis is a statistical technique that allows to identify underlying linear patterns in a data set.

It allows to express a data set in terms of other data set of significatively lower dimension without much loss of information. Read more.

What is Advanced Analytics?

Advanced Analytics

Advanced Analytics is the set of techniques used to discover intricate relationships, recognize complex patterns or predict current trends in your data.

The objective is to model data from internal and external variables to obtain useful insights that results in smarter decisions and better business outcomes. Read more.

Market Basket Analysis using R and Neural Designer

Market basket analysis using r

In this article, our objective is to analyze a dataset from a grocery store to create a recommendation system.

This system will be capable of generating accurate recommendations about products that the user may have an interest in. Read more.

3 methods to deal with outliers

An outlier is a data point that is distant from other similar points. They may be due to variability in the measurement or may indicate experimental errors.

In this post, we talk about 3 different methods of dealing with outliers. Read more.

The perceptron neuron model

There are many different types of neuron models, from which the perceptron is the most important one.

In this article we explain the mathematics on this neuron model. Read more.

6 testing methods for binary classification

Testing analysis

Depending on the type of problem that we are analyzing, there are some specific methods that may help us to study in depth the performance of the predictive model.

In this article, we focus on the 6 most used testing analysis methods for binary classification problems. Read more.

Electricity demand forecasting

electricity demand forecasting

Forecasting of power demand plays an essential role in the electric industry. It provides the basis for making decisions in power system planning and operation.

The objective of this article is to explain all the factors that lead to demand change and to determine the underlying causes. Read more.

FLIP2G Project

Neural Designer participates in the the R&D project "Enhancing education and training through data-driven adaptable games in flipped classrooms (FLIP2G)".

This project is framed in the Erasmus+ Programme of the European Union to support education, training, youth and sport in Europe. Read more.

Improving risk assessment using Advanced Analytics

Insurance risk image

Nowadays, the risk assessment process carried out by insurance companies has became obsolete.

By analyzing the available information on the customers stored by the company, we can develop risk models that evaluate new customers in a faster and more accurate fashion. Read more.

Customer segmentation using advanced analytics

Telemarketing is a form of direct marketing that is widely used by all types of companies. This technique can be extremely powerful at generating sales, but it requires a strict selection of potential clients.

Advanced Analytics allows us to select individual targets, which results in increased profitability. Read more.

6 Applications of predictive analytics in business intelligence

Predictive analytics extracts information from data sets to discover complex relationships, recognize unknown patterns, forecasting actual trends, find associations, etc.

This allows us to anticipate the future and make the right decisions. Read more.
