# `Chicken Vocalization Classifier`
|
| 19 |
+
|
| 20 |
+
This model is designed for classifying chicken vocalizations into categories indicative of health status or environmental noise. It serves as a crucial audio-based component within the "Chicken Health & Behavior Detection" multimodal project, aiming to aid in the early detection of poultry diseases and the monitoring of farm conditions.
|
| 21 |
+
|
| 22 |
+
## Model Description
|
| 23 |
+
|
| 24 |
+
The `chicken-vocalization-classifier` is a Convolutional Neural Network (CNN) built with PyTorch, designed to process Log-Mel Spectrogram representations of audio recordings. It categorizes chicken sounds into three classes: `Healthy`, `Noise`, and `Unhealthy`. This model can help identify abnormal vocalizations (e.g., coughing, distress calls) that might signal health issues, or distinguish between relevant chicken sounds and general farm noise.
|
| 25 |
+
|
| 26 |
+
## Training Data
|
| 27 |
+
|
| 28 |
+
This model was trained using the "Poultry Vocalization Signal Dataset for Early Disease Detection".
|
| 29 |
+
|
| 30 |
+
## Training Procedure
|
| 31 |
+
|
| 32 |
+
The model was implemented and trained using the PyTorch framework
|
| 33 |
+
|
| 34 |
+
* **Model Architecture:** The model, named `ModdifiedModel`, consists of a `features` extractor and a `classifier` head.
|
| 35 |
+
* **Features Extractor (Sequential):** Composed of three blocks, each containing a `Conv2d` layer, `BatchNorm2d`, `ReLU` activation, and `MaxPool2d`.
|
| 36 |
+
* Block 1: `Conv2d(1, 32, kernel_size=3)`, `BatchNorm2d(32)`, `ReLU()`, `MaxPool2d(2)`
|
| 37 |
+
* Block 2: `Conv2d(32, 64, kernel_size=3)`, `BatchNorm2d(64)`, `ReLU()`, `MaxPool2d(2)`
|
| 38 |
+
* Block 3: `Conv2d(64, 128, kernel_size=3)`, `BatchNorm2d(128)`, `ReLU()`, `MaxPool2d(2)`
|
| 39 |
+
* **Classifier (Sequential):** Contains a `Flatten` layer, two `Linear` layers, `Dropout`, and `ReLU` activation.
|
| 40 |
+
* `Linear(in_features=25088, out_features=256)`
|
| 41 |
+
* `Dropout(0.5)`
|
| 42 |
+
* `ReLU()`
|
| 43 |
+
* `Linear(in_features=256, out_features=3)` (for 3 classes)
|
| 44 |
+
|
| 45 |
+
* **Preprocessing:** Audio files are converted to Log-Mel Spectrograms using `librosa`.
|
| 46 |
+
* `SAMPLE_RATE = 22050` Hz
|
| 47 |
+
* Audio is sampled to approximately 1.5 seconds (`WAV_SIZE = int(1.5 * SAMPLE_RATE)`)
|
| 48 |
+
* `MEL_BANDS = 128`
|
| 49 |
+
* `N_FFT = 2648`
|
| 50 |
+
* `HOP_LENGTH = 256`
|
| 51 |
+
|
| 52 |
+
* **Data Splitting:** The dataset was split into training and testing sets using `train_test_split` with `test_size=0.2` and `random_state=27`
|
| 53 |
+
* **Loss Function:** `nn.CrossEntropyLoss()`
|
| 54 |
+
* **Optimizer:** `torch.optim.Adam` with a learning rate (`lr`) of `0.001`
|
| 55 |
+
* **Epochs:** The model was trained for `30` epochs
|
| 56 |
+
* **Batch Size:** Training was performed with a `batch_size` of `32`
|
| 57 |
+
|
| 58 |
+
