Una xarxa neuronal artificial \u00e9s un model inform\u00e0tic inspirat en el funcionament de les neurones del cervell hum\u00e0. \u00c9s la base sobre la qual s’aixeca bona part dels sistemes d’intel\u00b7lig\u00e8ncia artificial actuals.<\/p>\n<\/div>

<\/div>

Com s’inspira en el cervell?<\/h2><\/div>

Igual que el cervell est\u00e0 format per neurones connectades, una xarxa neuronal artificial est\u00e0 feta de nodes (tamb\u00e9 anomenats neurones) organitzats en capes i connectats entre si. Cada connexi\u00f3 t\u00e9 un pes: un valor que indica quina import\u00e0ncia t\u00e9 aquella informaci\u00f3 dins la xarxa.<\/p>\n<\/div>

<\/div>

Com apr\u00e8n?<\/h2><\/div>

Durant l’entrenament, la xarxa ajusta aquests pesos a poc a poc. Compara les seves respostes amb els resultats correctes i es va corregint una vegada i una altra. Aquest proc\u00e9s repetitiu \u00e9s el que li permet recon\u00e8ixer patrons, com distingir un gat d’un gos en una foto o captar el to d’un text.<\/p>\n<\/div>

On s’utilitza?<\/h2><\/div>

  • Reconeixement d’imatges i de veu<\/li>\n
  • Traducci\u00f3 autom\u00e0tica<\/li>\n
  • Sistemes de recomanaci\u00f3<\/li>\n
  • Models de llenguatge com ChatGPT o Claude<\/li>\n<\/ul>\n
