Industries
AI in Commercial Fishing Fleets
AI helps fishing fleets find fish more efficiently, cut wasted bycatch, and prove their catch is legal and sustainable.
IndustriesAI in Funeral and Memorial Services
AI is entering the funeral industry to handle logistics, personalize tributes, and even recreate the voices and likenesses of the deceased.
Visual AIMuse Masked Generative Imaging
Muse is a text-to-image model from Google that generates pictures by filling in masked image tokens all at once, making it far faster than step-by-step…
Visual AIParti Pathways Autoregressive Imaging
Parti (Pathways Autoregressive Text-to-Image) generates pictures the way language models write sentences: one image token at a time, predicting the next…
Visual AIImagen 2 and Reward-Tuned Diffusion
Imagen 2 is Google's photorealistic diffusion-based text-to-image model, refined with reward tuning so its outputs better match what people actually want.
Language AISelf-Refine Iterative Output Improvement
Self-Refine is a prompting technique where a language model critiques its own output and rewrites it, looping until the answer improves.
Language AILeast-to-Most Prompting
Least-to-Most prompting breaks a hard problem into a sequence of simpler subproblems, solving them in order so each answer feeds the next.
Language AIAnalogical and Step-Back Prompting
Analogical and Step-Back prompting both guide a model to reason at a higher level first: analogical prompting has it recall similar solved problems…
Audio AIGlow-TTS Monotonic Alignment
Glow-TTS is a text-to-speech model that learns to align text to speech on its own using a clever search trick, removing the need for a separate aligner.
Audio AIParallel WaveGAN Vocoder
Parallel WaveGAN is a fast neural vocoder that turns a mel-spectrogram into a raw audio waveform using a small GAN, generating all samples at once.
Audio AIWaveGlow Flow-Based Vocoder
WaveGlow is a flow-based neural vocoder from NVIDIA that synthesizes speech waveforms from mel-spectrograms in a single pass without autoregression.
ApplicationsAI in Player Scouting and Recruitment
AI in player scouting uses data and video analysis to spot talent, predict career trajectories, and find undervalued athletes.
