Continuous behavior data requires segmentation and clustering to reveal these embedded motifs. The popularity of automatic behavior quantification is growing, but existing solutions are often tailored to specific needs and are not designed for the time scale and precision required in many experimental and clinical settings. Here we propose a generalized framework with an iterative approach to refine both segmentation and clustering. Temporally Aligned Segmentation and Clustering (TASC) uses temporal linear alignment to compute distances between and align the recurring behavior motifs in a multidimensional time series, enabling precise segmentation and clustering. We introduce an alternating-step process:  \nevaluation of temporal neighbors against current cluster centroids using linear alignment, alternating with selecting the best non-overlapping segments and their subsequent reclustering. The framework is evaluated on semi-synthetic and real-world experimental and clinical data, demonstrating enhanced segmentation and clustering offering a better foundation for consequent research. The framework may be used to extend existing tools in the field of behavior research and may be applied to other domains requiring high precision of time series segmentation.  \nIntroduction  \nNeuroscience experiments investigating behavior and its underlying mechanisms, have been traditionally confined to observing and quantifying either constrained movement or limited subsets of it 1, in both experimental animal models and in human subjects. Behavior quantification in those scenarios could be approximated either by using the experimental setup, e.g., the timing between a cue and a lever press can help approximate timing and characteristic  \nof a reaching movement 2, or be meticulously labeled by a trained expert 1,2 . Moreover, it is common to group behaviors over repetitive trials, which allows to investigate behavior and neuronal characteristic of each group 1. However, such methods cannot be applied to the natural behavior experiments due to the lack of the strict setup and trial organization, nor can the manual labeling scale up to complex behavioral or clinical experiments. Recent advancementsin sensor technology, signal analysis, and especially machine learning, have catalyzed a shift towards automated approaches for behavior analysis 3.  \nBehavior quantification forms the basis for analyzing the mechanisms governing normal and pathological behaviors. Two crucial steps towards behavior quantification are segmentation and clustering 4. Segmentation is a process that entails dividing the data embedded within a continuous time series into short periods (segments), each representing a recurring subbehavior, often termed behavior motif (Fig. 1) . The latter refers to assigning such segments into meaningful clusters, each representing a single underlying sub-behavior. The two are often approached separately, but when coupled can enhance bot","cbCairQUs0yoTyxS","https://ap.wps.com/l/cbCairQUs0yoTyxS","pdf",1010083,23,"English","# Introduction\n## Behavior quantification: segmentation and clustering\n## Challenges in experimental and clinical behavior data\n## Behavior motifs across time scales","[{\"question\":\"What problem does TASC address in behavior analysis?\",\"answer\":\"TASC addresses the need to segment and cluster continuous behavior data to reveal recurring motifs with high temporal precision.
