    Very good video! Just a recommendation: It would be better to specify that this is the Agglomerative Clustering, which is a specific type of hierarchical clustering, in which one starts with all points being in their own cluster. There is also Divisive Clustering, in which we iteratively divide already existing clusters, starting from a single cluster that contains all points.
    Great video!

    The Euclidean distance horizontal component at 2:17 should be 3 not 4 since 4 - 1 = 3. Also, the manhattan distance should be 4 and the maximum distance should be 3 for the same reason.

    • @playbros332
      @playbros332 Год назад +1

      I agree they are wrong, but shouldn't it be square root of 17, which is 4.12?

    • @fabianr9394
      @fabianr9394 Год назад

      Because you go 3 steps to the right and 1 up; so sqrt(3^2 + 1^2)​@@playbros332

    • @Oladayo1
      @Oladayo1 10 месяцев назад

      well, that's because it's the sqrt of 10 not sqrt of 17. The mistake was using 4 instead of 3

    How might be the sqr of 17 (16+1) =equal to 3,162 ? it must be 4,123 is not?

    • @manuelruelas3496
      @manuelruelas3496 Год назад +4

      The error is that the x distance is 3 (from 1 to 4) not 4, so it’s the sq root of 10.

    I would like to ask, is Hierarchical Cluster Analysis always associated with the Euclidean Distance? Thank you

    • @datatab
      @datatab  9 месяцев назад

      Hi many thanks for your question, Hierarchical Cluster Analysis (HCA) is not always associated with the Euclidean distance. While Euclidean distance is commonly used, HCA can work with various distance metrics depending on the nature of the data and the analysis goals.
      Here are some common distance metrics used in HCA:
      - Euclidean Distance: This is the straight-line distance between two points in a multi-dimensional space. It's one of the simplest and most widely used distance metrics.
      - Manhattan Distance (also known as City Block or L1 distance): This is the sum of absolute differences between coordinates. It can be suitable when diagonal movement isn't meaningful.
      - Cosine Similarity: This measures the cosine of the angle between two vectors, commonly used in text analysis and other contexts where vector magnitude might vary.
      - Mahalanobis Distance: It accounts for correlations in data by incorporating the covariance matrix, making it suitable for data with different scales and correlations among variables.
      - Minkowski Distance: A generalization of Euclidean and Manhattan distances, with a parameter 'p' to control the degree of the norm.
      - Correlation-based Distance: This distance uses the correlation between data points rather than absolute differences. It's common in gene expression analysis or other contexts where relationships between variables matter more than absolute values.
      I hope this was helpful : ) Regards Hannah

      Hi, in this case you would first calcualte the center between Lisa and Joe and then the diestance from this center to one other Person. Regards Hannah
