Answer:

Early school starting times cause poor performance on tests, inattention in class, and drowsiness.

Explanation:

Carskadon study on early school starting time showed that it cause increased rate of rapid eye movement sleep in students and they doze off during lecture. Insufficient sleep lessens attentiveness levels in the class which affects students' potential to learn. The study showed that students do not perform well on tests. In addition to the difficulty in learning, there is an increased danger of accidents for those who drive to school due to dizziness.

Could Anyone Please Explain To Me What Is Supervised Learning In Machine Learning? I encourage that you explain it in simple wor
nadya68 [22]

Answer:

Kindly check Explanation.

Explanation:

Machine Learning refers to a concept of teaching or empowering systems with the ability to learn without explicit programming.

Supervised machine learning refers to a Machine learning concept whereby the system is provided with both features and label or target data to learn from. The target or label refers to the actual prediction which is provided alongside the learning features. This means that the output, target or label of the features used in training is provided to the system. this is where the word supervised comes in, the target or label provided during training or teaching the system ensures that the system can evaluate the correctness of what is she's being taught. The actual prediction provided ensures that the predictions made by the system can be monitored and accuracy evaluated.

Hence the main difference between supervised and unsupervised machine learning is the fact that one is provided with label or target data( supervised learning) and unsupervised learning isn't provided with target data, hence, it finds pattern in the data on it's own.

A to B mapping or input to output refers to the feature to target mapping.

Where A or input represents the feature parameters and B or output means the target or label parameter.

Suppose you have a program P and 90 percent of P can be parallelized, but 10 percent of P is inherently sequential and cannot be
EleoNora [17]

Answer:

Means no matter how many processors you use, speed up never increase from 10 times.

Explanation:

If a problem of size W has a serial component Ws,then performance using parallelism:

Using Amdahl's Law:

Tp = (W - Ws )/ N + Ws

Here, Ws = .1,

W - Ws = .9

Performance Tp = (.9 / N) + .1

---------------------------------------------------------

Speed Up = 1 / ( (.9 / N) + .1)

If N -> infinity, Speed Up <= 10

Means no matter how many processors you use, speed up never increase from 10 times.
