We have high-bias unregularized weak classifier that classifies each point correctly with training accuracy of 52%.
How do you suggest to improve its performance? Discuss all possible approaches.
Step by step
Solved in 3 steps
- What is a reasonable evaluation metric for measuring the prediction performance of a classification model on data that has class imbalance? (Class imbalance is when you have two classes in the data that are not equally represented and one class has significantly more instances than the other) Accuracy Precision F1-Score RecallDiscuss the application of “accuracy” in classification problems. Is it good or bad to measure the performance of a classifier? Give example to back up your argument. Explain why?Why do we use z-scores to evaluate a classifier? Why do we use feature weighting?
- Write Pattern for our dynamic adaptive criteria?To what end do we do testing in the context of BC/DR preparation? If yes, how many distinct types of tests are available?You’ve just finished fitting a logistic regression model for email spam detection, and it is getting abnormally bad performance on both your training and validation sets (AUC of 0.55 on Train and 0.53 on Validation dataset). You know that your implementation has no bugs, so what could be causing the problem? a. You are underfitting b. You are overfitting.

Make sure to say why you chose each approach. Note: Please need a short answer in 4/5 sentences.thanksThere are various benefits to using k-fold Cross Validation in error estimates over the usual strategy of dividing available data into training and test sets, which is described below. Give two benefits and explain why they are important??

This dataset is messy, full of incomplete/missing and erroneous data. Your task is to build a classification model on these records but you are concerned about the quality of the data handed to you. After consulting your colleagues you get an advice to chain two models: 1. the first model will de-noise the data and transform it into a better and complete representation of itself 2. the second model will take the output of the first model and classify the data What type of artificial neural network would you consider for your first model? Group of answer choices Autoencoder Convolutional neural network (CNN) Generative adversarial network (GAN) Multi-layer perceptron (MLP) Recurrent neural network (RNN)
