If you carefully examine the results of different folds when training, sometimes the accuracy of the results of some of these folds is not as good as the others. That is, they are not trained like other folds. For example, local maximums or local minimums may have locked our calculations, and there may be other reasons. But the question is:

Is it possible to ignore some folds in the cross-validation method? Is it possible that this will cause our score to increase? And what points should be observed?

The name of this equation has always been associated with concepts such as “Bifurcation” and “Chaos”. Finally, in the 1970s, Feigenbaum was able to compile a list of “R” values in which bifurcation occurs. Of course, he only used a programmable calculator. He was amazed when he calculated the convergence speed of the “R” values. Because this value was constant. Even when he looked at some similar equations, he was surprised to find that the convergence rate of “R” values was similar. This amount has been used as “Feigenbaum Constant” for many years by scientists around the world.

Currently, Machine learning techniques can only use the patterns that they have already seen. It means that initially certain patterns are set for the machines and then they are exposed to the pertinent data so that they can learn new skills. But like humans, could machine in the future answer the reasoning questions they have never seen before? Could machines learn complex and abstract tasks just from a few examples? This was exactly the theme of the recent abstraction and reasoning challenge, which terminated recently, and it’s one of Kaggle’s most controversial challenge.

The electricity consumption of Bitcoin mining is really staggering. Cambridge University has recently launched an online system provides a real-time estimate of the total electricity consumption of the Bitcoin network and updated every 30 seconds. Usually, the yearly average of power consumption for all mining equipment is estimated to be between 50 to 70 terawatt-hours(TWh) per year. This figure exceeds the annual consumption of a country with ten million populations and costs billions of dollars. In this short article will show such significant cost is covering from what resource.

In “Smart Blockchain”, one or more block producers smart contract (BPSC) is present in the network, and no successful transaction is performed without BPSC involvement. For a successful transaction in the network, first, the sender must send the cryptocurrency to the wallet of BPSC and then BPSC sends cryptocurrency automatically to the receiver. This simple action has led the BPSC to have all network transactions’ data accurately and flawlessly and then as an accurate and trust financial institution, record transactions’ data into a new block and add this new block to the end of the blockchain so there would be no task for miners in Smart Blockchain.

Bitcoin’s transactions, in addition to serious environmental damage, are much more expensive than conventional transactions. But users pay directly only a small portion of the miners’ fees as a transaction’s fee. A large portion of their remuneration is paid as a miner’s award. These new Bitcoins have an inflationary impact on the Bitcoin market, and indirectly all the Bitcoin holders are paying for it, but practically, no one pays attention to this part of the cost.

Smart Blockchain is the new generation of Blockchain networks that will allow one or more smart contracts to collect accurate and flawless data from the successful transactions of a decentralized network at the moment of transaction occurrence, and simultaneously storing and registering these data in new blocks. Smart Blockchain needs neither the financial institution nor intermediary, in addition, there will be no task to do for miners and block producers in this technology.
