Data and Modeling in AI-Powered Signal Processing Applications
Learn the basics of AI for signal processing and the tasks associated with preparing signal data and modeling a deep learning application.
Read ebookSignal Labeling and Dataset Management
With MATLAB, you can use built-in apps and domain-specific tools that can help you prepare your signal data with tasks such as labeling and managing large volumes of signal data that are too large to fit in memory.

Time-Frequency Transforms
Time-frequency representations describe how the spectral content in a signal evolves as a function of time. You can train deep learning networks which can identify and extract patterns from the time-frequency representations. You can also choose from a variety of techniques that can generate time-frequency representations for signals, including spectrogram, mel-frequency spectrogram, Wigner-Ville, and continuous wavelet transform (or scalograms).

Preprocessing and Feature Extraction
Signal preprocessing is a crucial step for enhancing overall signal quality. You can use built-in functions and apps for cleaning up signals and remove unwanted artifacts before training a deep network. You can also extract standard and domain-specific features from signals to reduce data dimensionality for training deep learning models. You can also use automatic feature extraction techniques, such as Wavelet Scattering, to obtain low-variance features from signals and train deep networks.

Signal Generation and Acquisition
Deep learning models typically require large amounts of data for training and validation. In certain situations, the availability of data can be the limiting factor in adopting deep learning techniques. With MATLAB and other add-ons for signal processing applications, you can simulate synthetic data that closely matches real-world scenarios and develop models using deep learning techniques. You can interface MATLAB with external hardware to acquire real-world data for the purposes of validating your trained models via early prototypes.
