"Ecstasy" was a popular drug in the 1990s. It produced a sense of euphoria derisively called the "yuppie high." One investigator

made a careful sample survey to estimate the prevalence of drug use at Stanford University. Two assistants were stationed on the main campus plaza and instructed to interview all students who passed through at specified times. As it turned out, 39% of 369 students interviewed said they had used Ecstasy at least once. Does the investigator’s procedure give a probability sample of Stanford students? Answer yes or no, and explain.

Answer

Yes

Explanation:

According to the Central Limit Theorem, the sample size, being n larger than 30, is representative of the Standford students´ use of the drug, in this case, being ecstasy. Another reason why the procedure works is the random sampling, where the assistants made sure that the only characteristic that mattered was being a student; gender, major being pursued, age, etc. were not of relevance.

Anthropological survey of such rituals gives a peek into societies with no surviving written history.

Explanation:

Modern native cultures are the ones that have survived a rigorous process of termination and getting westernized.

To safeguard them, the anthropologists need to document their rituals and decode their dances for possible symbols and way of life as it developed in the place when there was no issue of the extinction

It is only through the dances and rituals of these people can we get a peek into what their core values are and how their history has been in the absence of any written records.

DisPFL: Towards Communication-Efficient Personalized Federated Learning via Decentralized Sparse Training
Andreas93 [3]

Our decentralized sparse training technique, which requires that each local model in Dis-PFL only maintain a set number of active parameters during the whole local training and peer-to-peer communication process, substantially reduces communication and computation costs.

<u>What is DisPFL?</u>

  • It is suggested that personalized federated learning be used to address the issue of data heterogeneity among clients by developing unique, locally adapted models specifically for each user.
  • But because existing works are frequently constructed in a centralized manner, there is a great deal of communication pressure and vulnerability in the event that the central server is attacked or fails.
  • Using a decentralized (peer-to-peer) communication protocol called Dis-PFL, we offer a unique personalized federated learning framework in this study that uses personalized sparse masks to tailor sparse local models on the edge.
<h3><u>What is Communication?</u></h3>
  • Every communication has a sender, a message, and a recipient at a minimum. Although it might seem straightforward, communication is actually a very complicated topic.
  • There are a wide variety of factors that can influence how a message is transmitted from the sender to the recipient.
  • These include our feelings, the surrounding cultural context, the communication method, and even our geographic location.
  • Accurate, effective, and unambiguous communication is actually very difficult, which is why companies all over the world place such a high value on these abilities.

Detailed tests show that Dis-PFL dramatically reduces the communication bottleneck for the busiest node among all clients while also achieving improved model accuracy with lower computation costs and communication rounds.

anygoal [31]

Answer:

Preoperational

Explanation:

The preoperational stage of learning is the first stage where a person learns a language. In this stage a person cannot form sentences as they do not understand concrete logic. This makes it not possible to manipulate information which is required to make sentences and speak. It is also not possible to another person's perspective.

Hence, Thad was passing through the Preoperational stage of cognitive learning.
