Answer:
The VLookup checks a value inside a table through matching over the 1st column.
Lookup a value in a table by matching on the first column and the matched value is returned from the table.
Explanation:
The formula for the VLOOKUP is
=VLOOKUP (value to be matched in the first column, table from which the value will be looked for, col_index is the column inside the table from where the value is fetched, [range_lookup] is true for the approximate match, and false for exact match)
Answer:
statClass.java
Explanation:
You use the classname of the public class.
One of those will contain main()
Note that this example has a typo. statClass vs startClass.
Answer:
The various reasons that could be a major problem for the implementation are it involves a large number of parameters also, having a noisy data
Explanation:
Solution
The various reasons that could be causing the problem is given as follows :
1. A wide number of parameters :
-
In the ensemble tree method, the number of parameters which are needed to be trained is very large in numbers.
- When the training is performed in this tree, then the model files the data too well.
- When the model has tested against the new data point form the validation set, then this causes a large error because the model is trained completely according to the training data.
2. Noisy Data:
- The data used to train the model is taken from the real world . The real world's data set is often noisy i.e. contains the missing filed or the wrong values.
- When the tree is trained on this noisy data, then it sets its parameters according to the training data.
- As regards to testing the model by applying the validate set, the model gives a large error of high in accuracy
