Bayes’ Theorem provides a way that we can calculate the probability of a piece of data belonging to a given class, given our prior knowledge.
P(class|data) = (P(data|class) * P(class)) / P(data)
Where P(class|data) is the probability of class given the provided data.
Explanation:
- Naive Bayes is a classification algorithm for binary and multiclass classification problems.
- It is called Naive Bayes or idiot Bayes because the calculations of the probabilities for each class are simplified to make their calculations tractable.
This Naive Bayes tutorial is broken down into 5 parts:
Step 1: Separate By Class : Calculate the probability of data by the class they belong to, the so-called base rate. Separate our training data by class.
Step 2: Summarize Dataset : The two statistics we require from a given dataset are the mean and the standard deviation
The mean is the average value and can be calculated using :
mean = sum(x)/n * count(x)
Step 3: Summarize Data By Class : Statistics from our training dataset organized by class.
Step 4: Gaussian Probability Density Function : Probability or likelihood of observing a given real-value. One way we can do this is to assume that the values are drawn from a distribution, such as a bell curve or Gaussian distribution.
Step 5: Class Probabilities : The statistics calculated from our training data to calculate probabilities for new data. Probabilities are calculated separately for each class. This means that we first calculate the probability that a new piece of data belongs to the first class, then calculate the second class, on for all the classes.
Answer: Extraction phase
Explanation: Transactional database is the data collection capable of undoing the transaction that has not been correctly done. Data warehouse id the place where transaction data is transmitted where different types of databases are stored.
The transmission of the information from transactional database to data warehouse is defined in the extraction phase.The extraction phase works by transforming the data into a particular format. It copes the transactional databases's data to the warehouse by making separate space for deposition of data
The answer is virtualization
Virtualization is the creation of virtual versions of something
such servers, storage devices, operating systems, that allows one to share an
application or a resource among multiple customers or organizations. It plays a
critical role in cloud computing through sharing data that is present in the clouds
like application and infrastructure.
Answer: Registers
Explanation:
Registers are small storage locations identified by different types of registers. The function of the register is to provide data for immediate processing to the CPU. These registers hold data temporarily and provide easy access of data to the processor.
You will start to get ad pop-ups like crazy, and your computer will be a lot slower. I'd recommend that you be careful downloading things, make sure it's the right thing you're downloading. Some people make false websites. Also the best thing to do is get a usb drive and store everything you want to keep and reset your computer to factory in your settings.
