Supervised Learning - Classification Week 9 Challenge

  5. Import first 1500 rows of tables (College_A_HS, College_A_SE, College_A_SJ, College_B_HS, College_B_SE, College_B_SJ) into MS Excel.    

A company has customer data that contains 8 columns of customer details and another table having name customer_policy data contains the policy details of the customer.  The company intends to offer some discount in premium for certain customers. To do that they ask their Data scientist team to get some information. Hence,…

1. How does similarity is calculated if data is categorical in nature Categorical data are converted to numerical data using label encoding or one hot encoding then when comparing two records if the value for the categorical data is the same in both records then the similarity measure is zero if the values are…

-- Data cleaning on Automobile 1985 dataset and perform descriptive analytics I have worked on the dataset for conversion of raw data into a form that will make it easy to understand & interpret, ie., rearranging, ordering, and manipulating data to provide insightful information about the provided data. The dataset…

1. What is a Neural Network? Neural networks are a class of machine learning algorithms used to model complex patterns in datasets using multiple hidden layers and non-linear activation functions. Neural networks, also known as artificial neural networks (ANNs) or simulated neural networks (SNNs), are a subset…

1. Apply knn to the “Surface defects in stainless steel plates” and identify the differences See the document below   2. What are the pros and cons of knn     K- Nearest Neighbors or also known as K-NN belong to the family of supervised machine learning algorithms which means we use labeled (Target…

Pros and cons of SVM “Support Vector Machine” (SVM) is a supervised machine learning algorithm that can be used for both classification or regression challenges. However,  it is mostly used in classification problems. In the SVM algorithm, we plot each data item as a point in n-dimensional…

1)Calculate all 4 business moments using pen and paper for the below data set?   sol: See the Document in pdf     2)What is the significance of expected value when simple mean (Sum of all observations/number of observations) is already in place It is true that a simple mean is sufficient enough for having…

1. Why there is a difference in the formula of variance for population and sample The main difference between population variance and sample variance relates to the calculation of variance. Variance is calculated in five steps. First mean is calculated, then we calculate deviations from the mean, and thirdly the deviations…

A genetic algorithm is a search-based optimization technique based on the principles of genetics and natural selection. It is frequently used to find optimal or near-optimal solutions. we can apply the genetic algorithm that is not well suited for the standard optimization algorithm.
