Understanding Time Series Forecasting Challenges
Time series forecasting is complex and unpredictable, making it hard to accurately predict future values. Traditional forecasting methods provide only a single value, which doesnβt reflect the range of possible outcomes. While deep learning has improved accuracy, these methods often need specific training and donβt work well across different data types. To build effective forecasting models, we must overcome these limitations.
Current Forecasting Models
Forecasting models fall into two main categories:
1. Statistical Models
These models, like ARIMA and Exponential Smoothing, are easy to understand but struggle with complex data.
2. Deep Learning Models
Transformer-based models show great predictive power but require extensive training and can struggle with data representation.
