-DT is an predictive algorithm that build models in the form of a tree structure, that is composed of a series of branching Boolean tests (tests for which the answer is true or false). The princpel is to use these boolean tests to split the data into smaller and smaller subsets to identify patterns that can be used for prediction. [Noel Cosgrave slides]

-In a DT, each '''internal node''' represents a "test" on an attribute (e.g. whether a coin flip comes up heads or tails), each '''branch''' represents the outcome of the test, and each '''leaf node''' represents a class label (decision taken after computing all attributes). The paths from root to leaf are called '''decision rules/classification rules'''. https://en.wikipedia.org/wiki/Decision_tree

-* What is the inductive bias in Decision Tree learning?
+<li style="margin-bottom: 30px; margin-top: 30px">[[Web App - Library Management System]]</li> <section end=portfolio_programming  />
-:* Shorter trees are preferred over longer trees: Smaller trees are more general, usually more accurate, and easier to understand by humans (and to communicate!)
-:* Prefer trees that place high information gain attributes close to the root

-* More succinct hypotheses are preferred. Why?
-:* There are fewer succinct hypotheses than complex ones
-:* If a succinct hypothesis explains the data this is unlikely to be a coincidence
-:* However, not every succinct hypothesis is a reasonable one.

-=====The ID3 algorithm=====
-ID3 (Quinlan, 1986) is an early algorithm for learning Decision Trees. The learning of the tree is top-down. The algorithm is greedy, it looks at a single attribute and gain in each step. This may fail when a combination of attributes is needed to improve the purity of a node.
+:* '''[[Some important concepts]]'''
+</div>
+</div>
+<section end=it />
-At each split, the question is "which attribute should be tested next? Which logical test gives us more information?". This is determined by the measures of '''entropy''' and '''information gain'''. These are discussed later.
+<div class="divline1" style="padding: 0; border: 0; display: block; margin-right: -20px; margin-left: -20px; background-color: white; height:1.3pt"> </div>
-A new decision node is then created for each outcome of the test and examples are partitioned according to this value. The process is repeated for each new node until all the examples are classified correctly or there are no attributes left.

-=====The C5.0 algorithm=====
-C5.0 (Quinlan, 1993) is a refinement of C4.5 which in itself improved upon ID3. '''It is the industry standard for producing decision trees'''. It performs well for most problems out-of-the-box. Unlike other machine-learning techniques, it has high explanatory power, it can be understood and explained.
