Transformers, introduced in the “Attention is All You Need” paper, effectively model long-term dependencies in sequential data, making them highly valuable for predictions in time series data.

PredictionOverview: Text input, numeric output: AI methods like Transformers can be effectively used to predict numeric values using text as the input. For example, they can be used to predict house prices based on textual property descriptions found in real estate listings.

Overview: Image input, numeric output: AI can be used to predict a numeric value when given an image. For example, predicting someone’s age based on their photo.

Example Tools: Google’s Teachable Machine, Azure Computer Vision, Amazon Rekognition.

Overview: Audio input, numeric output: In a manufacturing context, a model could be trained to predict the Remaining Useful Life (RUL) of machinery based on audio recordings of its operation. This AI model, trained on audio data labeled with the known remaining operational hours of corresponding machines, learns to associate specific sound patterns with the machinery’s lifespan.

Overview: Video input, numeric output: AI can be used to predict a numeric value based on a video. For example, predicting the speed of a baseball pitch. The model would be trained on numerous video clips of pitches, where each clip is labeled with the actual speed of the pitch as recorded by a radar gun.

Example Tools: Google Cloud Video Intelligence API, Amazon Rekognition Video, Azure Video Indexer.
