Linearregression - Study guides, Class notes & Summaries

Linear Regression Open the attached .csv file. Select Regression from the data analysis tab Weight will be our predictor variable and MPG the response variable. Select your x (predictor) and y (response) ranges accordingly. Check the labels button and and output cell. Observe the ANOVA matrix. The F-statistic will tell you whether your model is better than simply using the mean. You will want the F-statistic to be as high as possible and the significance to be as low as possible. The equati...

QMB 3302 Final Verified A+ NLP stands for ️️Natural Language Processing Tokenization, as defined in the lecture is... ️️a computer turning letters and/or words into something it can read and understand, like numbers Recommenders come in many flavors. 2 of the most common, often used together and discussed in the lecture are: ️️1) Item Based 2) User Based Imagine you have a dataset with 2 columns, both filled with continuous numbers. You believe the first column is a p...

5 steps to building a machine learning model - 1. choosing a class of model 2. choose hyperparameters 3. arrange data 4. fit the model 5. predict a silhouette score of 1 is the [best/worst] and -1 is the [best/worst] score - best, worst basic idea of regression - we have some X values called features and some Y value, the variable we are trying to predict Difference between unsupervised and supervised learning - unsupervised: you have an X but no Y supervised: you have an X and a Y Ima...
