The decision tree is a classification model, applied to existing data. If you apply it to new data, for which the class is unknown, you also get a prediction of the class. The assumption is that the new data comes from the similar distribution as the data you used to build your decision tree. In many cases this is a correct assumption and that is why you can use the decision tree for building a predictive model.

∙ 11y agoAn inference is a conclusion which can be about anything; it could be a prediction of something that you expect to happen in the future, but it could also be your interpretation of something that happened in the past. I might infer that the reason why you are eating a lot of food at lunch because you did not eat breakfast. That is not a prediction.

Difference between discrimination and classification in datamining?
There is only a slight difference between discrimination and classification in data mining. Discrimination can be negative and classification is generally just factual.
What is the difference between defect prevention and prediction?
defect prevention includes those strategies through which we avoid to occur a defect. for example formal risk analysis, prototyping. in defect prediction those areas are highlighted where there is possibility that defect can occur.
What is the difference between clustering and classification?
I've been looking for this aswer about a few months, and nothing! Researching on it, I believe that both are same. But, with only one markable difference: clustering is a type of unsupervised learning, and classification is a type of supervised learning. I believe that it is the only difference, and, of course, this dictates the way that the algorithm starts. But the results are essentially similar: grouped data.Good luck in your question. I hope I've helped!

What is the difference between observation infferrence and prediction?
Observation is the act of noticing and recording something that has been directly perceived. Inference involves making logical conclusions based on observations and prior knowledge. Prediction is a statement about what will happen in the future based on observations, inferences, and patterns.

What are the differences between anticipation and prediction in listening exercises?
Anticipation in listening exercises involves preparing for what you expect to hear based on context or prior knowledge, while prediction involves guessing specific details about what will be said. Anticipation is more general and helps with overall comprehension, while prediction is more specific and focuses on guessing the exact content or words that will be used. Both are important skills for effective listening.
What is the difference between earthquake forecast and earthquake prediction?

What is the difference between a prediction and observation?
prediction is when you do not know what will happen but you guess that it will happen. observation is when you see something

Difference between family and order in classification?
In classification, family is a higher level of organization that groups together similar genera. It is a taxonomic rank below order. Order is a higher taxonomic rank than family and groups together similar families.
Difference between observation and prediction?
Prediction: What you think (or claim to think) before the experiment. Observations: What you saw happen.

Really, there is no difference except for the name, and the fact that a hypothesis is a bit more formal.

What is the difference between a prediction and a conclusion?
A prediction is what you think will happen BEFORE the experiment is followed through with, a conclusion is what you observe and conclude after the experiment has been completed.
