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).

The school encourages students to use recycled materials in their models and presentations – not only is it sustainable, but also cost effective and potentially innovative. The school also offers subsidies for exhibition costs. The original contributions presented in the study are publicly available.

You can mix a combination of hot coffee with sweeteners like sugar or condensed milk, spices like nutmeg, cinnamon, or cardamom, and rum like Pyrat Rum XO Reserve. Or if you’re wanting something refreshing for the summer, you could chill your coffee, and then mix any combination of these ingredients over ice instead. Dunn T. W., Marshall J. D., Severson K.

The Bartlett School of Architecture enjoys an unrivalled reputation within the UK's architecture industry, having been voted the best architecture school by the Architects' Journal AJ100 for seventeen consecutive years. Our students enjoy networking opportunities, including Open Crits and the annual Summer Show of student work, to which influencers and industry leaders are invited. Gulley J. M., Hoover B.

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.

In the example above, two areas representing objects in distinct positions were passed as input, and the output is a DataFrame with the timestamps of each object interaction. The function PlotInteraction() plots object interactions across time ( Figure 2D). 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!
