Checklist Cyprus AI Camp 2026 IOAI Selection Camp · Task 8
The Last Frequency
Classify 1-second 16 kHz recordings into 35 spoken commands from raw waveforms.
The task
In a 2051 story, a voice-controlled bunker under the Troodos Mountains misrecognises commands. Contestants train a network to classify 35 commands (directions, actions, digits and words) from a subset of Google Speech Commands v2.
Audio is given as raw waveforms (16,000 samples, normalised to [-1, 1]); the representation (mel-spectrogram 2D CNN or raw-audio 1D CNN) is the contestant's choice.
Abridged by SOTA from the official materials. The official statement has the exact rules, and it wins wherever this summary differs.
At a glance
- You get
train_waveforms.npy(N×16000),train_labels.npy,public_test_waveforms.npy,private_test_waveforms.npy,label_map.json,sample_submission.csv.- You submit
- CSV with Id and Command (one of the 35 command strings) for all public and private test samples.
- Scoring
- Accuracy; points = max(0, min(100, (accuracy − 0.40) × 166.67)).
- Rules
- Pre-trained models and additional data are not allowed unless the task says otherwise.
- No outside help; LLM chats, ChatGPT, Copilot and similar tools are prohibited (except Colab inline autocompletion).
- Only the Kaggle website and Google Colab may be used (no local IDEs); online library documentation is allowed.
- One Kaggle account per participant; leaderboard name '[City] Name Surname'.
