Algorithm and Modeling in Data Analysis Assignment
- 1. ALGORITHM AND MODELING IN DATA ANALYSIS ASSIGNMENT
- 2. DECISION TREE MODELS The scoring algorithms has been known as decision tree models. They have been utilized to develop the decision rules on the basis of known categories. Alternatively, there are relationships which are going to be applied for the unknown data. We have come across the algorithms which will be classed as two general centers. They are rule induction models. It is also known as decision trees. There is unsupervised learning. Alternatively, there might be clustering techniques.
- 3. DATA MODEL The data model plans the data elements. It creates a standard of the nature of data elements associated with one another. As the data elements record the real life personalities, things and places, there are events between those elements. The reality is represented by the data model. They are going to demonstrate data required and developed by the processes of business.
- 4. ALGORITHM The algorithm has been a method we obey to obtain something or solving the problem. The model has been calculation or the formula created as the outcome of the algorithm which shows certain values in the form of input and creates certain value in the form of output.
- 5. DETERMINISTIC ALGORITHM The deterministic algorithm represents the output which is not changing in various runs. PCA is going to provide same outcome when the team has been running again. But this is not k-means.
- 6. MACHINE LEARNING ALGORITHMS The machine learning algorithms are as follows: Linear Regression Logistic Regression Linear Discriminant Analysis Classification and Regression Trees Naive Bayes K-Nearest Neighbors Learning Vector Quantization Support Vector Machines
- 7. FIVE STEPS Step 1: Follow the application workflow. Step 2: Model those queries essential in the application. Step 3: Creating a table design. Step 4: Find out the primary keys. Step 5: Utilizing the perfect data types in the right way.
- 8. LEARNING ALGORITHM The learning algorithm represents a method utilized in the processing of data to find out the patterns perfect for the application in the new position. The goal is to choose the system to the particular task of input-output transformation.
- 9. DISADVANTAGE OF K-MEANS The major disadvantage of K-Means indicates the non-deterministic condition. K-Means begins with the group of the data points in the form of the initial centroid. There is a random selection motivating standard of resulting clusters. Every run of algorithm for same dataset is going to obtain a new output.
- 10. PREDICTIVE MODELING The predictive modeling involves the statistical technique utilizing the machine learning along with the data mining activity. They are going to forecast the outcomes in the future. It has been assisted by the historical data. It functions through the analysis of the present and the historical data. It projects the knowledge of model created to predict the outcome.
- 11. STEPS OF THE DATA MODELS Conceptual Model: For the step, there is requirement of data stated in the model, which shares the business concepts to stakeholders of business. Logical Model: There is a logical model recording the structure of a data and organizes it to apply in a particular database.
- 12. APPLICATION OF LANGUAGE OF DATA MODELING In order to apply the data to be structured easily, they have been validated, grouped, and replicated. They are going to share the finite and proper network elements which could not be modified.
- 13. DATA MODEL Data model is going to include the entity types, relationships, attributes, integrity rules, along with explanation of the objects. It has been utilized as the beginning of interface design or database design.
