Chapter 423 The Quantum Competition Begins!
It is very common for the weather forecasts we use on a daily basis to be inaccurate.
Sometimes, even when it has started raining outside, the weather forecast still shows that it will be sunny today.
Inaccurate weather forecasts often catch people off guard.
"Not bad, it is basically consistent with our predicted data." Xu You said calmly.
Xu You seemed a little too calm about the news.
After all, in previous simulations, Xu You had determined that the accuracy of this weather forecast model was extremely high.
Such a high prediction accuracy is inseparable from the near-perfect model constructed by Xu You.
In addition, the terrifying calculation speed of "Suanjing" is another key.
The same prediction model, even using the computing power of the island quantum computer, is simply unable to complete such a huge amount of calculations.
The "Suanjing" quantum computer and this weather prediction model are connected with a very high degree of fit.
Half a month later.
More detailed statistics are available.
Because there are too many factors that affect the weather, the accuracy of weather forecasts has declined to a certain extent as the forecast period has lengthened.
But the overall accuracy is still above the theoretical value.
Even weather that other weather forecast platforms cannot successfully predict one day in advance, "Suanjing" can accurately predict it a week in advance.
Such a result shocked the entire project team.
"Professor Xu is amazing. He was able to determine the prediction accuracy of this model without any verification. It's not an exaggeration to say that he can predict the future like a god, right?"
"I really shouldn't have doubted Professor Xu at that time. He is the one who knows the performance of the 'Suanjing' best. No matter how powerful the vulture is, it can't reach the level of the 'Suanjing'."
"This time we are predicting the weather, and in the future we may even be able to simulate the evolution of the universe. The reason why we cannot achieve 100% accuracy now is not because our calculation ability is insufficient, but because we do not have enough information. If technologies such as radar satellites can be more advanced, the weather in the longer term can also be accurately predicted."
Han Shubin was also amazed by the achievements of "Suanjing".
Even though Han Shubin had unconditionally supported Xu You before, he had never had such high psychological expectations for "Suanjing"'s performance.
A genius like Xu You cannot be viewed with ordinary eyes.
…
Another half a month passed, and the performance of "Suanjing" in weather forecasting still met expectations.
During this period, Xu You continued to summarize and slightly improve the success rate of "Suanjing" for weather forecasts by fine-tuning the details.
It can be said that "Suanjing" has already brought computing power to its extreme within the existing capabilities.
If we want to further improve the accuracy, we should not make adjustments to the computing power and model, but to the satellites and radars.
Although as the prediction period lengthens, the prediction accuracy of "Suanjing" will decline to a certain extent.
However, "Suanjing" can still continuously update weather forecast information according to the latest situation to improve the accuracy of weather forecasts.
When it comes to weather forecasts within three days, the "Suanjing" can be almost completely trusted.
As time goes by, the "quantum competition" between Huami and Xiaomi is finally about to begin.
To some extent, this quantum race feels a bit like the space race of last century.
Not only Huami and Xiaomi, but people from other countries in the world are also paying close attention to this quantum competition.
This represents the highest level of computing in the world and is likely to change people's lives in the future.
To this end, many mainstream media in the world will broadcast the entire quantum competition live.
"The first phase of the quantum competition will use weather forecasting as the criteria for consideration, and the competition will last for a month. The quantum computers of both parties will forecast the weather for more than 10,000 cities around the world based on the radar satellite data of their respective countries. Factors such as the accuracy of the weather forecast and the length of the forecast period will be taken into consideration."
In terms of specific performance evaluation, both parties have unified a scoring system as the standard.
Generally speaking, the more accurate the weather forecast is and the longer the forecast period is, the higher the score will be.
For various reasons, the first phase of the quantum competition cannot be completely fair.
In addition to the randomness of the weather, the two sides did not use the same radar satellite system, and the data they could obtain were different.
However, both sides trust their own radar satellite data more and insist that their own data is more accurate.
As long as both parties have no objection to this, such "unfairness" can be considered relatively fair.
"At 00:00 tomorrow morning, Jijing time, the Suanjing quantum computer and the Vulture quantum computer need to submit their respective weather forecast data on time. The time interval for real-time data refresh is 24 hours, and data cannot be modified during this period."
After all, this is a competition. It is not like a real weather forecast where data can be refreshed in real time based on the latest situation.
Otherwise, it would be difficult to judge the winner.
Before the data submission deadline, many people around the world were waiting for this moment to come.
In some places, it was even midnight, but everyone still wanted to review the data submitted by both sides before going to bed.
Wanting to know about these two quantum computers is secondary to local weather forecasts.
What everyone wants to know more is how different the prediction reports on quantum computers are in the next two days.
Because this is the key to determining victory or defeat.
At one o'clock, Suanjing and Vulture submitted their weather forecast data for major cities around the world for the next month.
At the same time, this information will be published on the Internet for netizens from all over the world to query.
Although every 24 hours, both sides have the opportunity to update the data.
But this time the weather forecast report has largely determined the outcome of the battle between the two sides.
"After comparing the data, the overlap between Suanjing and Vulture for the weather forecast for the next 24 hours is as high as 95%. This shows that the weather forecasts for the next 24 hours are highly consistent. However, as the forecast period increases, the overlap between the two sides becomes lower and lower. For three days, it is only 80%, and for seven days, it is only 60%. For data within a month, the overlap is very low."
Such data differences indicate that the models used by both sides are completely different.
The reason for this is probably not due to the difference in radar satellite data.
