  1. Why do multi-label music taggers often use separate sigmoid outputs rather than a single softmax over tags?
    • All tag probabilities must sum to one
    • A recording is required to have exactly one tag
    • Sigmoid outputs eliminate the need for labeled examples
    • Several nonexclusive tags can apply to the same recording
  2. Ndeipi inomiririra inomiririra yakawanda yemazuva ano-auto-tagging modhi inodyisa mune yavo neural network?
    • A mel-spectrogram (mufananidzo wenguva-frequency)
    • Iyo mbishi waveform amplitude kukosha chete
    • Iyo MP3 faira metadata minda
    • Sheet-mimhanzi notation
  3. Nei chiyero chemel chichishandiswa pachinzvimbo cheiyo plain linear frequency scale?
    • Inodzvanya mafaera zvakanyanya
    • Inobvisa ruzha rwese kumashure
    • Inofananidzira kuti vanhu vanoona sei pitch
    • Zvinodiwa nemutemo wekodzero
  4. Nderipi dambudziko rakakura paunenge uchidzidzira otomatiki mamodhi pane chaiyo-nyika dataset?
    • Mafaira ekuteerera idiki kwazvo kuti udzidze kubva
    • Ma tag anoiswa nevanhu ane ruzha, haana kukwana, uye haana kuenzana
    • Iko hakuna ruzhinji mimhanzi dataset
    • Spectrograms haigone kuverengerwa munguva chaiyo
  5. Ndeipi dataset inowanzoshandiswa kudzidzisa uye kuenzanisa mimhanzi auto-tagging masisitimu?
    • MagnaTagATune
    • ImageNet
    • SQUAD
    • LibriSpeech
  6. What additional search interface can an audio-language model such as CLAP support for a music catalog?
    • Guaranteed identification of every artist without audio input
    • Automatic replacement of all rights metadata
    • Searching only by the recording's compressed file size
    • Retrieval using free-form text descriptions rather than only fixed tag names
  7. Which objective commonly trains separate binary tag predictions in a music auto-tagger?
    • A single mutually exclusive genre softmax only
    • Binary cross-entropy over the tag outputs
    • A pixel-reconstruction loss on album artwork only
    • A loss requiring exactly one positive tag per track
  8. If a music dataset's annotations are incomplete, how should an absent instrument tag be interpreted?
    • It proves the recording has no instruments
    • It guarantees that the tagger's positive prediction is wrong
    • It may be unannotated rather than reliable evidence that the instrument is absent
    • It means the waveform cannot be used for evaluation
