The correct number of clusters in Hierarchical clustering can be determined precisely using approaches such as silhouette scores (True or False) - correct answer False In K Means clustering, the analyst does not need to determine the number of clusters (K), these are always derived analytically using the kmeans algorithm. (True or False) - correct answer False One big difference between the unsupervised approaches in this module, and the supervised approaches in prior modules: Unsupervised...

True. There exists a convergence proof. - Answer K-means is a clustering algorithm that is guaranteed to converge. False. A delayed reinforcement learning task is one where the optimal solution can only be found by associating incoming rewards with a whole sequence of previous actions, instead of just the latest one. The reward may very well be received in every time step also in delayed reinforcement learning. - Answer The main difference between immediate and delayed reinforcement lea...

You may use any of the following resources: One sheet(both sides) of handwritten (not photocopied, scanned, or printed) notes If any question seems ambiguous, use the most reasonable interpretation (i e don't be like Calvin): Instructors know about the issue in a private Piazza post afterwards. Good luck! 1...

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...

According to the documentation, a silhouette score of -1 is - The worst score According to the documentation, a silhouette scores of 1 ia - The best score All the the nodes prior to the output nodes essentially 'guess' at the correct weights. Then the algorithm checks to see if the initial guess is correct (usually not). When it is wrong... - It tries again (runs another epoch) An example this week was done in a Jupiter like environment called Google Collab. What was the language that wa...
