Clustering is an unsupervised learning technique that aims to identify patterns that consist of similar or interrelated observations within data [39, 87]. Many existing clustering algorithms are often categorised into three primary groups [39, 82]: partitioning algorithms such as K-Means [39] and Spectral Clustering [88], hierarchical algorithms such as Single Linkage [39] and HDBSCAN* [7, 8], and soft (fuzzy or probabilistic) algorithms such as Fuzzy c-Means (FCM) [4] and Expectation Maximisation with Gaussian Mixture Models (EM-GMM) [20]. Partitioning clustering algorithms partition data into a given number of k clusters, while hierarchical clustering algorithms produce a sequence of nested partitions with incrementally varying numbers of clusters. Soft clustering algorithms are similar to partitioning techniques except that each data observation is assigned a degree of membership or probability to each cluster, rather than a full assignment to a single cluster. It is worth mentioning that within the aforementioned categories there are clustering algorithms that may not necessarily assign all observations to clusters, due to outlier trimming or noise detection. Two examples of such algorithms are trimmed K-means [14] and the previously mentioned HDBSCAN*, each of which may produce solutions where not all observations are assigned to clusters. Clustering validation or validity is an important step of the clustering process irrespective of the algorithm used [39, 25], as it is crucial to determine the best produced partition(s) and number of clusters within the data [23].

A smart speaker makes for an easy first step into smart home technology. Before you kit out your house with thousands of dollars of lighting and security upgrades, you can familiarize yourself with voice-assistant technology while enjoying music, podcasts, and news in a hands-free home environment. Here are our top picks in several categories. If you want information about smart speakers in addition to our top recommendations, scroll down the page to read our in-depth buyers' guide. Alexa is the most popular voice assistant, and the 2024 edition of the Echo Pop is the best value in Amazon's smart speaker lineup. While it's not a true smart display, it is equipped with a touchscreen that can display the time, date, weather conditions, and other information. It can also show album art while streaming music (not that we recommend this speaker for that task).

One notable trend at CES earlier this year was the quirky robot vacuum. It seemed every third booth had a new model that could climb stairs, pick up socks, serve drinks and, oh yeah, suck up dirt from your floor. Now that Amazon's Spring Sale is here, we're seeing lots of discounts -- not on those wacky prototypes, but on robo vacs that make keeping your floors clean easier and automated. Engadget has two guides to these handy home gadgets, based on years of testing and reviewing products from brands like iRobot, Shark, Dyson, Eufy and more. Here are the best deals on robot vacuums and cordless stick vacs we could find for the Big Spring Sale. This "essential" Roomba is relatively no-frills, but it has the added benefit of being a mopping robot in addition to a vacuum.
