Write an example of Recursive Flow Classification algorithm using python
Recursive Flow Classification algorithm
def recursive_flow_classification(data, classes):
If there are no more data points, return
if len(data) == 0:
returnCalculate the entropy of the data
entropy = calculate_entropy(data)
Find the best attribute to split on
best_attribute = find_best_attribute(data, classes)
Create a new node with the best attribute
new_node = Node(best_attribute)
Split the data based on the best attribute
subsets = split_data(data, best_attribute)
Recursively build the tree for each subset
for subset in subsets:
recursive_flow_classification(subset, classes)Return the tree
return new_node

YOUR DAILY DYSTOPIA | 2017.04.17

The White House has responded to the protests in Berkeley, California over a speech by a controversial editor. White House Press Secretary Sean Spicer said that the protest was "not a representation of our great country," and that "to turn away speakers of different points of view shows an intolerance that just is not American."
The United Nations has criticized the US for its continued use of drones in targeted killings, saying that the US "failed to comply with international law." The UN also noted that US drone strikes have resulted in the deaths of innocent civilians.
The US Department of Justice has opened a civil rights investigation into the death of a mentally-ill black man who was shot and killed by police in Sacramento, California. The investigation will focus on determining if the Sacramento Police Department has a pattern of excessive force against minorities.
The US Senate has approved a bill that would make it easier for veterans to access health care, despite opposition from some Republicans. The bill would provide veterans with more options for receiving care outside of the Veterans Affairs system.
A new report has found that the number of homeless people in the US has reached a record high, with over half a million people currently living on the streets. The report also found that the number of homeless veterans has increased by nearly 10 percent since the previous year.
The US Supreme Court has declined to hear a case that challenges a North Carolina law that requires transgender people to use public restrooms according to the gender listed on their birth certificates. The Court's decision not to hear the case leaves in place a lower court ruling that upheld the law.
In a move that has been condemned by human rights groups, the Trump administration has approved the sale of more than $500 million worth of weapons to Saudi Arabia. The weapons are intended for use in the Saudi-led war in Yemen, and will include laser-guided bombs and other precision-guided munitions.
The US Department of Justice has dropped its investigation into a former CIA official who was accused of leaking classified information to the press. The official has been cleared of all charges, and the DOJ has said that there is insufficient evidence to press charges.
The Environmental Protection Agency has proposed new regulations that would limit the amount of carbon dioxide emissions from coal-burning power plants. The proposed regulations would require power plants to reduce their emissions by 32 percent by 2030.
Finally, the US government has imposed new sanctions on Russian officials and companies in response to the country's interference in the 2016 US election. The sanctions will target individuals and organizations that have been linked to the Russian government.

Java实现监听 tibco queue
Java可以利用JMS API来实现对Tibco queue的监听。具体实现如下:
-
创建JMS ConnectionFactory,可以从Tibco EMS Server中获取,用于建立JMS连接。
-
使用ConnectionFactory创建JMS Connection,其中可以指定Tibco EMS Server的连接参数,如主机地址、用户名、密码等。
-
使用Connection创建JMS Session,其中可以指定是否启用事务机制,以及是否自动确认消息等参数。
-
使用Session创建JMS Queue,用于接收消息。
-
创建JMS MessageListener,用于接收到消息时的回调处理。
-
使用Session创建QueueReceiver,指定要监听的Queue和MessageListener。
-
启动Connection,此时QueueReceiver就可以接收到来自Queue的消息,并调用MessageListener的onMessage方法进行处理。

中国制造业整体节奏放缓原因
中国制造业整体节奏放缓主要原因有以下几点:
1、我国投资增速放缓。由于政策限制和资金紧张,企业投资增速放缓,导致企业投资意愿不强,拖累了制造业发展。
2、贸易保护主义抬头。我国对外贸易受到贸易保护主义的抬头影响,进出口总值出现下降,制造业部门也受到影响,制造业发展出现放缓。
3、企业技术落后。我国制造业企业技术落后,生产效率低,出口竞争力弱,不能适应市场变化,拖累了制造业发展。
4、劳动力成本上升。随着劳动力成本的不断上升,制造业企业的利润空间不断缩小,企业投资意愿不强,导致制造业发展放缓。
