Applications of sequence data and sequence modeling in machine learning

Sequential data is a kind of data with temporal or sequential nature, such as time series data, natural language text and speech. The order of data points is critical to understanding the underlying pattern or meaning. To process and analyze sequential data, sequential modeling techniques are used in machine learning and artificial intelligence.

In a sequential model, data is passed and processed sequentially through a series of layers to extract features. These layers are stacked together in a specific order to enable the transformation of data. The first layer is the input layer, which receives the original input data, and the last layer is the output layer, which generates the final prediction or output. Typically, there will be one or more hidden layers between them to process the data and extract features. This sequential architecture enables neural networks to gradually learn and understand complex relationships in data and make accurate predictions and classifications.

Examples of Sequential Data

Time series data, such as stock prices, weather data, and sensor readings, are typically collected at regular intervals. The order in which this data is collected is critical to understanding trends and patterns.

Natural language text, such as a book, article, or sentence. The order of words and sentences is important in understanding the meaning and context of the text.

Video, the order of video frames is important to understand the movement and actions of objects in the video.

Image sequence, such as CT scan sequence, MRI image or satellite image in the medical field. The order of the images is important in understanding how the images change over time.

Several popular sequential modeling methods

• Recurrent Neural Network (RNN)
• Long short-term memory Network (LSTM)
• Gated Recurrent Unit (GRU)
• Transformers
