 ## `News`
 - For the interested students, we can find [here](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/tree/master/notebooks/X_deep_learning) two demo/tutorial notebooks on deep learning for image classification (convolutional neural nets) with the tensorflow 2.X platform and Keras API.
-- For students who have to stay at home for health reasons, and *only those who can't attend the face-to-face course*, there is a zoom link (see the [chamilo page](https://chamilo.grenoble-inp.fr/courses/PHELMA5PMSAST6/index.php?) of the course) to participate in videoconference to the class every monday from 15:45 to 17:45.

+# Lab 6 statement
+
+The objective of this lab is to illustrate basic concepts of clustering.
+
+_Note: For each notebook, read the cells and run the code, then follow the instructions/questions in the `questions` or `Exercise` cells._
+
+See the notebooks in the [`7_Clustering`](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/blob/master/notebooks/7_Clustering/) folder
+
+
+1. Implement your own version of Kmeans in 1D for Euclidean distance  [`N1_Kmeans_basic.ipynb`](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/blob/master/notebooks/7_Clustering/N1_Kmeans_basic.ipynb)
+and compare the obtained results with Sklearn Kmeans implementation.
+
+2. Apply Kmeans algorithm (Sklearn implementation) to the classical Iris dataset [`N2_KMeans_iris_data_example.ipynb`](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/blob/master/notebooks/7_Clustering/N2_KMeans_iris_data_example.ipynb)
+
+3. Implement a Kernelized version of Kmeans, and test the importance of adequate parametrization or choice of initial conditions
+ [`N3_Kernel_Kmeans_example.ipynb`](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/blob/master/notebooks/7_Clustering/N3_Kernel_Kmeans_example.ipynb)
+
+4.  Implement your own version of EM for Gaussian model  and apply it to the same example used for Kmeans in a preceeding notebook. Compare with KMeans and interpret the results [`N4_EM_basic.ipynb`](https://gricad-gitlab.univ-grenoble-alpes.fr/chatelaf/ml-sicom3a/-/blob/master/notebooks/7_Clustering/N4_EM_basic.ipynb)
