How does sequence modeling work?
Sequence modeling trains AI systems on chronologically ordered data to capture patterns and make predictions over time. More specifically, sequence models like recurrent neural networks process inputs as sequences, with each data point conditioned on those preceding it.
The model iterates through data points, maintaining an encoded representation of the sequence history at each step. This sequential processing allows the model to learn complex time-based patterns like trends, seasonality, and long-range dependencies in data.
The sequence model is trained to make predictions by estimating the probability distribution over next values, given the sequence of past context. This modeling of ordered data as interdependent steps enables the model to develop a sense of continuity and dynamics within data.
By absorbing implicit rules about events unfolding over time, sequence models can gain limited foresight to make informed predictions about what may follow based on sequenced history. This time-based conditioning provides valuable context for inference compared to assessing data points independently. With extensive training over representative sequences, models can become skilled at leveraging the past to anticipate the future.
Why is sequence modeling important?
Sequence modeling is crucial for AI systems to understand data that unfolds over time. Unlike static data, temporal sequences have complex time-based patterns like trends, cycles, and lagged effects. By processing data as interdependent sequenced steps, models can learn these nuanced time dynamics rather than viewing data points in isolation.
This time-based conditioning enables models to make more contextual and accurate predictions and decisions — understanding how the past leads to the future. Sequence modeling has unlocked AI advancements in speech, text, video, forecasting, anomaly detection, and more.
Why sequence modeling matters for companies?
Sequence modeling can be used to discover invaluable insights from processes that evolve over time. It allows forecasting sales, demand, attrition risk, and other key metrics based on past sequences.
Companies can optimize scheduling, logistics, and operations using learned sequences. In anomaly detection, sequence models identify unusual temporal patterns. For process optimization, sequence modeling finds inefficiencies in workflows over time. In generative applications, it creates realistic text, audio, and video by capturing temporal patterns.
