1 2.3 Advanced analytics at your hands Neural Designer is the most powerful predictive analytics software. It uses innovative neural networks techniques to provide data scientists with results in a way previously unachievable. Predictive analytics is a technique that uses data available for organizations in order to predict with maximum certainty what will happen in the future. As a result, companies can anticipate and take appropriate decisions. TARGET APPLICATIONS Business intelligence Recently, new disruptive techniques for machine learning, such as deep learning, have been developed. Deep learning combines the best methods from artificial intelligence and data science to build powerful predictive models from large-scale data sets. Sales forecasting Customer segmentation Churn prevention Risk analysis Etc. Health care Organizations generate large amounts of data. A rising volume, velocity and variety are the three key features of big data. Therefore, companies need tools that are able to analyze more data in less time. They also need more reliable predictions to increase their competitive advantage. Neural Designer is an innovative solution for predictive analytics based on neural networks. It makes intelligent use of data by discovering complex relationships, recognizing unknown patterns or predicting actual trends. Medical diagnosis Medical prognosis Microarray analysis Protein design Etc. Industry 4.0 Output prediction Performance optimization Predictive maintenance Quality improvement Etc.

2 KEY BENEFITS Easy to use With Neural Designer there is no need for programming or building complicated block diagrams. Its user interface has been conceived to simplify data entry as well as the execution of the different tasks. The software comes with many tutorials and examples to help you learn how to use it, and our team provides specialized technical support to our customers through telephone, and Skype. Great visualization of results The Neural Viewer writes a report displaying comprehensive results from all tasks. Users can explore data and visualize the results with tables, charts and pictures that can be exported in order to be used in other tools. Also, the whole report displayed in the viewer can be exported to PDF format.

3 High performance Neural Designer outstands in terms of performance. The next figures summarize a capacity, accuracy and speed comparison among a data mining platform written in Java, a predictive analytics tool written in R and Neural Designer, which is written in C++. As we can see, Neural Designer is able to analyze data sets 100 to 1000 times bigger, is about 8 to 12 times faster and is 1000 times more accurate than its Java and R competitors. (The data-set to make the comparisons is available at ) Simple deployment Once the model is obtained, Neural Designer provides its mathematical expression. An example of that expression in the R programming language is written below. expression <- function(x) { scaled_x<-2*(x+1)/(1+1)-1 y_1_1<-tanh( *scaled_x) y_1_2<-tanh( *scaled_x) y_1_3<-tanh( *scaled_x) scaled_variable_2<-( *y_1_ *y_1_ *y_1_3) outputs <- c(0.5*(scaled_variable_2+1.0)*(1+1)-1) outputs }

4 The same expression in Python is listed next. from math import tanh def expression (x) : scaled_x=2*(x+1)/(1+1)-1 y_1_1=tanh( *scaled_x) y_1_2=tanh( *scaled_x) y_1_3=tanh( *scaled_x) scaled_variable_2=( *y_1_ *y_1_ *y_1_3) (variable_2) = (0.5*(scaled_variable_2+1.0)*(1+1)-1) return variable_2 The mathematical expression gives you direct access to your predictive model. It can be easily embedded into other software or any computer language.
