Drink Pyrat Rum with a mixer. Of course, there’s always the classic rum and coke option if you like to drink your rum in a long drink. Other sodas go well with rum too – try Pyrat Rum with ginger beer, lemonade, or tonic water. To top off your mixed drink, add a wedge of citrus fruit like lemon or lime to give a fruity edge. As Pyrat Rum XO Reserve has an especially orangey flavour, you could even garnish with an orange slice to accentuate that. Rossato J. I., Gonzalez M.

Publisher's Note

A common task in animal behavior analysis is the identification of distinct behaviors, such as rearing, grooming, nesting, immobility, and left and right turns. To automatically classify behaviors, we used a combination of two unsupervised approaches on each video frame. We used the hierarchical agglomerative clustering algorithm to label the clusters ( Lukasová, 1979) and a non-linear technique for dimensionality reduction called t-distributed stochastic neighbor embedding (t-SNE) to visualize the result ( Van der Maaten and Hinton, 2008). The input of both algorithms is the distances between labeled body parts. This approach was chosen because the relative distance between body parts is invariant to the animal position in the pixel space. Combining these techniques, we created a map where the distances between the body parts of each frame are transformed into 2D space using t-SNE and the color of each point is determined by the label from hierarchical agglomerative clustering ( Figure 3A). Rum is one of our favourite spirits – it’s tasty, versatile, and so very easy to drink! But there are more ways to enjoy rum that just mixing it with coke. Today we’re looking at some of the ways you can drink rum – perhaps you can try out something new!

Data Availability Statement

Shake all ingredients except Cranberry Juice, Strain over fresh ice and finish with soda Citrus Cooler To enhance cluster visualization, we optimize the t-SNE hyperparameters according to the heuristics reported in Kobak and Berens ( 2019). Their approach is based on three steps, (1) the use of Principal Component Analysis (PCA) in t-SNE initialization to preserve the data structure in lower dimensions; (2) set the learning rate as η = n/12, where n is the number of data points (frames); and (3) set the perplexity hyperparameter, which controls the similarity between points and governs their attraction, as n/100. In addition, we implemented three metrics to quantify the quality of the t-SNE output (Kobak and Berens, 2019), (1) the KNN ( k-nearest neighbors), which quantifies the preservation of the local structure; (2) the KNC ( k-nearest class), which quantifies the preservation of the mesoscale structure; and (3) the CPD ( Spearman correlation between pairwise distances), which quantifies the preservation of the global structure.
