   • Unsupervised Machine Learning Examples

     Unsupervised machine learning represents a pivotal domain within artificial intelligence, emphasizing the extraction of patterns and structures from data devoid of prior labeling. Unlike its supervised counterpart, which relies on labeled outcomes to guide predictions, unsupervised algorithms delve into the intrinsic characteristics of data to discern similarities, differences, and underlying patterns. This approach fosters autonomy in data analysis, allowing algorithms to uncover latent insights and segment data without human intervention.

     This article explores how Unsupervised Machine Learning Examples, provides examples across various domains, and answers frequently asked questions about its applications.

     What is Unsupervised Machine Learning?

     Unsupervised machine learning is a type of machine learning where algorithms learn from data that has no pre-defined labels or categories. In contrast to supervised learning where the training data is labeled (think “cat” pictures and “dog” pictures), unsupervised learning algorithms are tasked with finding hidden patterns or structures within the data itself.

     How Unsupervised Machine Learning Works?

     Unsupervised Machine learning algorithms explore data by looking for structures or patterns. The primary goal is to model the underlying structure or distribution of the data to learn more about the data....

   • Unsupervised Learning

     Unsupervised learning is a branch of machine learning that deals with unlabeled data. Unlike supervised learning, where the data is labeled with a specific category or outcome, unsupervised learning algorithms are tasked with finding patterns and relationships within the data without any prior knowledge of the data’s meaning. This makes unsupervised learning a powerful tool for exploratory data analysis, where the goal is to understand the underlying structure of the data.

     Unsupervised Learning

     In artificial intelligence, machine learning that takes place in the absence of human supervision is known as unsupervised machine learning. Unsupervised machine learning models, in contrast to supervised learning, are given unlabeled data and allow discover patterns and insights on their own—without explicit direction or instruction.

     Unsupervised machine learning analyzes and clusters unlabeled datasets using machine learning algorithms. These algorithms find hidden patterns and data without any human intervention, i.e., we don’t give output to our model. The training model has only input parameter values and discovers the groups or patterns on its own.

     Try MeanShift

     . From the sklean user guide of MeanShift:

     The algorithm automatically sets the number of clusters, ...

     Modified demo code:

     import numpy as npfrom sklearn.cluster import MeanShift, estimate_bandwidth# ############################################################################## Generate sample dataX = [1,2,4,7,9,5,4,7,9,56,57,54,60,200,297,275,243]X = np.reshape(X, (-1, 1))# ############################################################################## Compute clustering with MeanShift# The following bandwidth can be automatically detected using# bandwidth = estimate_bandwidth(X, quantile=0.2, n_samples=100)ms = MeanShift(bandwidth=None, bin_seeding=True)ms.fit(X)labels = ms.labels_cluster_centers = ms.cluster_centers_labels_unique = np.unique(labels)n_clusters_ = len(labels_unique)print("number of estimated clusters : %d" % n_clusters_)print(labels)

     Output:

     number of estimated clusters : 2[0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1]

     Note that MeanShift is not scalable with the number of samples. The recommended upper limit is 10,000.

     BTW, as rahlf23 already mentioned, K-mean is an unsupervised learning algorithm. The fact that you have to specify the number of clusters does not mean it is supervised.

     May be you want to see the spread of data, with respect to first two features. Then you have to slice it from the initial dataset instead from Series (as @Alexandre metioned)

     data = arff.loadarff("./Data/Arrhythmia/Arrhythmia_withoutdupl_02_v01.arff")df = pd.DataFrame(data[0])df = df.drop(['outlier',"id"],axis=1)plt.scatter(df.iloc[:,0],df.iloc[:,1])plt.show()

   What is the difference between supervised and unsupervised learning?

   • Supervised techniques deal with labeled data where the output data patterns are known to the system. This makes Supervised Learning models more accurate than unsupervised learning models, as the expected output is known beforehand. Unsupervised Learning models work on their own to discover the inherent structure of unlabeled data.

    To put it simply, supervised learning uses labeled input and output data, while an unsupervised learning algorithm does not. In supervised learning, the algorithm “learns” from the training data set by iteratively making predictions on the data and adjusting for the correct answer.
