Comp 541: project proposal
XXXXXXXXXXChronic Homelessness
Summary of the proposed project:
This work summarizes the challenges offered by homelessness service provision tasks, as well as the problems and the opportunities that exist for advancing both data science and human services. The problem is to know the social characteristics of homeless people to help them as best as possible and if it is possible to recognize homeless people based on the other data presented by the Dataset.
Research technique:
We will use R Code to analyze data about the homeless. We chose two different techniques to predict or to solve the problem of the dataset, these techniques are Random Forest model and Logistic Regression. Then we will use the two techniques to see if we can predict a homeless person. When we say multiple models are trained on a dataset, same model with different hyper parameters or different models can be trained on the training dataset. It combines the output of multiple decision trees and then finally produces its own output. Random Forest works on the same principle as Decision Tress; however, it does not select all the data points and variables in each of the trees. It randomly samples data points and variables in each of the trees that it creates and then combines the output at the end. It removes the bias that a decision tree model might introduce in the system. Also, it improves the predictive power significantly. We will see this in the next section when we take a sample data set and compare the accuracy of Random Forest and Decision Tree. The following steps
· Load and summarize the data.
· By deleting missing values, we have accidentally eliminated missing values as well as outliers. Therefore, no further treatment of the null values is required.
· Make a plot to compare Veteran and No Veteran.
· Make a frequency plot for quantitative variables split by Veteran.
· Frequency plots for qualitative variables, split by Veteran.
· Create training set and fit the final model to the training data. Generate predictions and bind them together with the true values from the test data.
Now, we will create a Random Forest model with default parameters and then we will fine tune the model by changing ‘mtry’. We can tune the random forest model by changing the number of trees (ntree) and the number of variables randomly sampled at each stage (mtry). According to Random Forest package description:
Ntree: Number of trees to grow. This should not be set to too small a number, to ensure that every input row gets predicted at least a few times.
Mtry: Number of variables randomly sampled as candidates at each split. Note that the default values are different for classification
· Using a loop to identify the right mtry for Random Forest Model.
· We will use a mtry of 5 to have a more accurate model. We will test the random forest model on our training set.
· Our training set has an e
or rate and has no e
or at the result. We will see if it is the same with our test set.
· This graphic shows the most important datatypes for the Random Forest Model. We will compare the Random Forest Model with Logistic regression Model
We implement two algorithms to make classification models. We will use ROC Curve for the two models to check the fitting of the data. The model with the highest ROC Score is considered the best model. Here, we created the data set using Bootstrap method. Where we generate data sets of the same size as data set earlier.
Use the model to predict the homeless rate in the testing data. We will use the best model as an example but should compare the performance of all models.
Conclusion:
The power of assembling and the importance of using Random Forest over Decision Trees. Though Random Forest produces its own inherent limitations (in terms of number of factor levels a categorical variable can have), but it still is one of the best models that can be used for classification. It is easy to use and tune as compared to some of the other complex models, and still provides us with a satisfactory level of accuracy in this scenario.

Introduction:
Our primary objective is to predict our response variable(required) using generalized linear model (Logistic regression) and linear Discriminant Analysis algorithm. We have compared thes
e models in order to maximize the accuracy. We have conducted exploratory data analysis before the model building for better understanding of dataset. we have considered “required” as response variable and remaining variable as in explanatory variable. We have also used stepAIC method for feature selection of logistic model.
Methods:
Logistic Regression:
This kind of factual analysis (otherwise called logit model) is frequently utilized for prescient examination and demonstrating, and stretches out to applications in AI. In this investigation approach, the response variable is limited or absolute: either An or B (Binary) or a scope of limited choices A, B, C or D (multinomial levels of response variable). It is utilized in measurable programming to comprehend the connection between the response variable and at least one explanatory factors by assessing probabilities utilizing a logistic regression model.
This kind of analysis can assist you with foreseeing the probability of an occasion it being settled on to a decision. For instance, you might need to know the probability of a guest picking a proposition made on your site — or not (response variable). Your analysis can take a Income at known attributes of Required. Calculated GLM models assist you with deciding a likelihood of what kind of guests are probably going to acknowledge the proposition — or not. Therefore, you can come to better conclusions about advancing your proposition or settle on conclusions about the actual deal.
Linear Discriminant Analysis:
Linear discriminant analysis is utilized as a device for classification and information representation. It has been around for a long while now. Regardless of its effortlessness, LDA frequently delivers strong, respectable, and interpretable classification results. While...
