New update in our blog by our Data Scientist Gabriel Garau.
This time we present a dynamic programming application to solve the Fibonacci series.
Dynamic programming (DP) is a computer programming method which consists in breaking down a complex problem into smaller problems, usually in a recursive way. Then, these problems are solved one at a time, typically storing the already computed results so as to avoid computing them more than once.
This simple example illustrates the importance of choosing an efficient way to tackle a problem, even when there are different alternatives yielding the same result. In this case, we saw that by just storing these values using a dynamic programming approach, overhead is dramatically reduced, especially as the number of nested calculations increases.

Demand forecasting and dynamic pricing
At Damavis, we present our hotel demand forecasting model and a dynamic pricing strategy in order to maximize the expected profits. Soon, the article will be available also in english.
The structure of the paper is organized by sections. In section 2 we describe the data set used. In section 3, we present the model for forecasting future demand, based on time series. In section 4, we explain how the above prediction is used to generate possible future scenarios through Monte Carlo simulations. In section 5, we study the effect of price on demand from historical data.
These results will be used in section 6 to calculate the optimal price on the simulations generated in section 4. In section 7 we present the results obtained in each of the previous sections. Finally, in section 8 we summarize the work done and propose possible lines of improvement.

Scala 3 is here
After 8 years of work, 28,000 commits, 7,400 pull requests, 4,100 closed issues – Scala 3 is finally out. Since the first commit on December 6th 2012, more than a hundred people have contributed to the project.
Today, Scala 3 incorporates the latest research in type theory as well as the industry experience of Scala 2. It has been seen what worked well (or not so well) for the community in Scala 2. Based on this experience the third iteration of Scala is created – easy to use, learn, and scale.

DELPHI, an artificial intelligence framework that predict high-impact research
MIT researchers have designed a machine learning framework that, by computing on the historical scientific research graph, is able to predict the future impact of scientific research.
The researchers see DELPHI as a tool that can help humans better leverage funding for scientific research, identifying “diamond in the rough” technologies that might otherwise languish and offering a way for governments, philanthropies, and venture capital firms to more efficiently and productively support science.
