# Decision Trees for Machine Learning and Data Science – Perfect Stepping Stones for a Successful Journey

Assignment Help  3rd Jun 2020

Decision trees models are designed by using these main steps and first step is Induction and another step is Pruning. The main fact is that Induction is a part that helps to build a tree that means this defines the entire set of information that helps to take the hierarchical decisions boundaries based on our data. Because of the base and idea of training decision trees, they can be prone to major over fitting. Apart from that pruning is the process that helps to remove the unnecessary structure from a decision tree, effective reducing the complexity to combat overfitting with the added bonus of making it even easier to interpret. To collect the additional information, you can easily collect with our writers and take the best information in the form of decision trees assignment help.

• Easy to Understand and interpret
• Require very little data preparations
• The cost of using the tree for interface is algorithmic in number of data points used to train the tree
Important Steps:  This is one of the high-level inductions that follow three main steps like:
• Begin with your training dataset that should have some additional features like variables, classifications and regression output.
• By using this step, we control the excellence feature like “Best feature” in the dataset to divided the data.
• Split the data into subsets that mainly contains the possible values for this best feature. This mainly helps to define a node on the tree and each node is a splitting point based on a specific feature from our data.
• Step1: Collect your data, we have to find the relevant data to start the process so that we can easily make the perfect sequence and deliver to the company.
• Step2: After collecting the data, we have to select the feature to use and define the split in commonly chosen by using a perfect algorithm to minimise the cost of a function. Here we have to work according to the requirements like if we think about it for a second, performing a split when building a decision tree is equal to dividing up the feature space. Here we need to take the decision wisely so that we collect the maximum benefits. With the help of machine learning, we can get the quality result and make the best algorithm. With the help of this algorithm we can easily share the information about each and every step-in perfect sequence so that we collect the maximum benefits from this.
• Step 3: Pruning: Because of the nature of the training decision trees they can be disposed to major overfitting. This is a best technique that leverages this splitting redundancy to remove or you can say that prune the unnecessary splits in our trees. From a high-level pruning compresses part of the tree from strict and rigid decisions boundaries into ones that are more smooth and better and it also helps to effectively reducing the tree complexity. We can simply define the complexity of a decision tree as the number of splits in the tree.
