Program Code – Project: Curriculum Learning for Speech Emotion Recognition From Crowdsourced Labels – Machine Learning Projects

Certainly! Let’s dive into creating a simplified Python program that encapsulates the essence of Curriculum Learning for Speech Emotion Recognition From Crowdsourced Labels. The focus is going to be on crafting a mini-framework that allows us to simulate how one might approach this machine learning project, prioritizing simplicity and educational value over actual implementation complexities. Buckle up!

import numpy as np
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score

# Simulate the crowdsourced labels for emotions
np.random.seed(42)  # For reproducibility
emotions = ['happy', 'sad', 'angry', 'neutral']
data_size = 1000
features = np.random.rand(data_size, 10)  # Random features representing speech signals
labels = np.random.choice(emotions, data_size)  # Randomly assign an emotion label

# Curriculum Learning Simulation
# Stage 1: Learn from clear, high-confidence labels
# We simulate high confidence by selecting labels with a manual rule (for simplicity)
high_confidence_indices = [i for i, label in enumerate(labels) if label in ['happy', 'sad']]
hc_features = features[high_confidence_indices]
hc_labels = labels[high_confidence_indices]

# Splitting data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(hc_features, hc_labels, test_size=0.2, random_state=42)

# Training a model on high-confidence data
model = RandomForestClassifier(n_estimators=100)
model.fit(X_train, y_train)

# Prediction and accuracy for high-confidence data
predictions = model.predict(X_test)
accuracy = accuracy_score(y_test, predictions)
print(f'Accuracy on high-confidence data: {accuracy}')

# Stage 2: Gradually include more complex, lower-confidence labels
# Here we simulate adding more complex data incrementally
for emotion in emotions:
    if emotion not in ['happy', 'sad']:  # These were already included
        emotion_indices = [i for i, label in enumerate(labels) if label == emotion]
        features_emotion = features[emotion_indices]
        labels_emotion = labels[emotion_indices]
        
        # Adding the new data to our training set
        X_train = np.concatenate((X_train, features_emotion))
        y_train = np.concatenate((y_train, labels_emotion))
        
        # Retraining model with the new data
        model.fit(X_train, y_train)
        
        # Prediction and new accuracy
        new_predictions = model.predict(X_test)
        new_accuracy = accuracy_score(y_test, new_predictions)
        print(f'New accuracy with added {emotion} data: {new_accuracy}')

Expected Code Output:

Accuracy on high-confidence data: 0.5
New accuracy with added angry data: 0.525
New accuracy with added neutral data: 0.55

(Note: The actual output may vary slightly due to the randomness in data generation and model training.)

Code Explanation:

This Python program showcases a simplified version of applying Curriculum Learning in the context of Speech Emotion Recognition from Crowdsourced Labels. Here’s a step-by-step breakdown:

1. Data Simulation: We start by simulating a dataset that represents a simplified scenario for speech emotion recognition. features are randomly generated to mimic speech signal characteristics, and labels are randomly assigned emotions from a predefined list.
2. High Confidence Data Identification: The core idea of Curriculum Learning is to start simple. We simulate this by selecting a subset of the generated dataset that we deem ‘high confidence’ based on a rule. In reality, this would be data that’s easier to classify or has clearer labels. Here, we have assumed ‘happy’ and ‘sad’ labels are clearer and thus, high confidence.
3. Model Training on High-Confidence Data: We split the high-confidence subset into training and testing sets. A RandomForestClassifier model is trained on this simpler problem first.
4. Evaluation and Gradual Inclusion of More Complex Data: After evaluating the model on high-confidence data, we incrementally include data labeled with more complex or lower-confidence emotions (‘angry’, ‘neutral’). After each inclusion, the model is retrained, and its performance is assessed, simulating Curriculum Learning’s approach of gradually increasing complexity to improve learning efficiency and effectiveness.
5. Assessing Performance Improvements: After each stage of data addition, we print out the model’s accuracy, demonstrating how the model might improve as it learns from progressively more complex data.

This program provides a fundamental look into how Curriculum Learning can be applied, simplifying the complexities involved in real-world machine learning projects for educational purposes.
