Time series data, which consists of repeated measurements taken at regular intervals, is used extensively in numerous fields, including economics, medicine, meteorology, and many more. Insights into past behaviours, present dynamics, and future predictions can be gleaned from the rich detail that is often present in these data sets. In this piece, we look at how sophisticated machine learning methods can be used to recognise patterns in time series data. Time series analyses that have been used in the past have been helpful, but they may not be able to capture the non-linear and complex patterns that are present in today's datasets. Due to their ability to self-learn complicated patterns without explicit programming or strong data assumptions, advanced machine learning techniques like deep learning neural networks, support vector machines, and ensemble approaches have showed significant potential in this domain. Our study provides a comprehensive review of these algorithms within the framework of time series pattern identification, elucidating their fundamentals, strengths, and potential limitations. We conduct a battery of experiments on different datasets to evaluate these algorithms and determine their strengths and weaknesses in comparison to more traditional methods. While state-of-the-art ML algorithms have shown encouraging results, our research shows that their performance heavily relies on hyperparameter tuning, data preprocessing, and model selection. Future developments in this area are also discussed, with an eye toward the increasing importance of interpretability in machine learning outcomes for time series data and the incorporation of hybrid models.
