Hi, I am Abutalha, and I have experience in building machine learning pipelines for classification problems, including audio processing, feature extraction (MFCCs, spectrograms), and model development using Python, TensorFlow, PyTorch, and scikit-learn. I can build an end-to-end pipeline covering data preprocessing, feature engineering, model training, evaluation (including macro-F1 and confusion matrix), and a clean inference system that runs efficiently on CPU with a simple loading interface or API setup. Before starting, could you share the approximate number of audio classes and total dataset size so I can suggest the most suitable model approach? Best regards, Abutalha.

✅ **Building accurate ML models is only half the job—the real challenge is creating a reproducible pipeline that consistently turns raw audio into reliable predictions.** Your project is a great fit for my AI/ML background. I can build an end-to-end audio classification pipeline covering data ingestion, feature extraction, model training, evaluation, and deployment-ready inference. **Approach** • Audio preprocessing and quality checks • Feature extraction (MFCCs, Mel Spectrograms, Chroma, or learned embeddings) • Training and evaluation using PyTorch, TensorFlow, or scikit-learn depending on dataset size • Hyperparameter tuning and experiment tracking • Confusion matrix, F1-score analysis, and model comparison • Packaged inference pipeline with a single prediction command or lightweight API I have experience building AI systems including recommendation engines, classification models, vector search pipelines, and production-ready ML workflows with a strong focus on performance and maintainability. For initial assessment, I'd like to review: • Number of classes • Samples per class • Average audio duration • Recording quality/format • Target accuracy expectations Once I see the dataset distribution, I can recommend the best architecture and realistic F1 targets. I'd be happy to review a sample dataset and outline the training strategy, evaluation process, and deployment approach. ?

Hi, I’d be excited to help build your end-to-end audio classification pipeline.

I will build an end-to-end audio classification pipeline using PyTorch. Here's my approach: Feature extraction: MFCCs + log-mel spectrograms. I'll experiment with both and compare. Librosa for audio loading. Model: CNN over spectrograms (standard for audio classification) or fine-tuned Wav2Vec2 if dataset is large enough. Fallback: Random Forest on MFCCs for quick baseline. Training: Stratified train/val/test split. Hyperparameter search via Optuna or grid search. Class weighting if imbalance exists. Output: Saved .pt model + inference script that loads an audio file and returns category in <2 seconds on CPU. Why me: I've built multiple end-to-end PyTorch pipelines (diffusion models, transformers, medical classifiers). I write clean, reproducible code with proper documentation. I don't know audio specifically yet, but I learn fast — I went from HTML to CUDA kernels in 9 months. Dataset size: 1,000-5,000 samples minimum for deep learning. 200-500 for classical ML. What do you have?
