Google uses machine learning make weather forecast from radar images. Google has joined a project to use machine learning in order to make a high-resolution and short-term forecast to predict rainfall using radar images.

The objective of this project, a research by Cornell University (United States), is to develop machine learning models for the forecast of highly localized rainfall and an immediate future. One of the advantages of introducing this technology is that the forecasts are almost instantaneous and with high native resolution.

Google uses machine learning make weather forecast

The forecasts cover between 0 and 6 hours since the search. These models are capable of generating forecasts with a resolution of one kilometer with a total latency of between 5 and 10 minutes, including delays in data collection and surpassing traditional models.

As Google explains from a statement, the study treated the forecast as a problem of image-to-image translation and with the use of a U-Net convolutional neural network (CNN) an image is presented that contains a channel for each image of multispectral satellite in the observation sequence of the last hour.

The final results demonstrated that the technology developed by Google is capable of surpassing the most common meteorological prediction models currently used up to a maximum of 5 or 6 hours, when the high-resolution fast update (HRRR) begins to overcome it.

This is how Alexis Sánchez was evaluated in Italy after his return to the courts in triumph of Inter

After three months off the court because of an ankle injury for which he had to be operated, Alexis Sánchez finally made his return with Inter Milan, and did so in the blunt 4-1 win against Cagliari, a result that He allowed the Lombard cast to advance to the quarterfinals of the Italian Cup.

The Chilean striker played a correct game, leaving showy moves, to finally be replaced at 69 minutes by the young Italian attacker Sebastiano Esposito.

Therefore, after the meeting the main Italian media highlighted the performance of the Tocopillano.

Eurosport qualified him with a 6.5 and indicated that "he returns to the field after more than 3 months and gains proficiency: he fights in each ball, often seeks dialogue with Lukaku and also acted in some of his goals. His condition will only improve, but the first indications are encouraging. "

The same note was given by the Passioneinter site, which pointed out that Sanchez "on each ball puts the usual quality and always creates something potentially insidious."

In turn, Calciomercato evaluated Sánchez with a 6 and said that "it is good, but it is returning from a long injury and a long journey."

While the newspaper Corriere della Sera gave him a 6.5 and said that "the Chilean has not played since September 29. After three months of inactivity, he finds Lukaku, the safest shoulder there is. He moves very well and speaks very good with your partner: it will be very useful from now on. "
