Model Training
Driven by an intense desire to understand data and fueled by the opportunities presented during the COVID-19 pandemic, I enthusiastically ventured into the vast world of Python, Machine Learning, and Deep Learning. Through online courses and extensive self-learning, I immersed myself in these areas. This led me to pursue a Master's degree in Data Science. To enhance my skills, I actively engaged in data annotation while working at Biz-Tech Analytics during my college years. This experience deepened my understanding and solidified my commitment to this field.
Understanding the roles of train, validation, and test data is essential for building robust matching learning models. Properly splitting and using the datasets ensures that the model generalizes well to new data, making it reliable and effective in real-world applications.
Train Data: Train Data is the foundational dataset for teaching the machine learning model. During the training phase, the model analyses this data to identify patterns and relationships that it will use to make predictions.
Validation Data: Validation Data is crucial for fine-tuning the model's hyperparameters and selecting the best version of the model. It acts as a checkpoint to ensure the model is not just memorizing the train data but also generalizing well.
Test Data: Test Data is used only after the model has been trained and validated. It provides an unbiased evaluation of the model's performance, simulating how the model will perform on new, unseen data.
| Train Data | Validation Data | Test Data | |
| Purpose | To enable the model to learn | To validate the model during training and prevent overfitting | To evaluate the model's final performance |
| Usage | Used iteratively during the training process | Used during the training process to adjust hyperparameters | Used after the training and validation phases are complete |
| Size | Usually, the largest portion of the dataset | Typically, a smaller portion of the dataset compared to train data | Generally similar in size to the validation |
