What options are available for setting a training budget in AutoML Tables?
Setting a training budget in AutoML Tables involves several options that allow users to control the amount of resources allocated to the training process. These options are designed to optimize the trade-off between model performance and cost, enabling users to achieve the desired level of accuracy within their budget constraints.
The first option available for setting a training budget is the "budget_milli_node_hours" parameter. This parameter represents the total amount of compute resources to be used for training, measured in milli-node hours. It determines the maximum duration of the training process and indirectly affects the cost. By adjusting this parameter, users can specify the desired trade-off between model accuracy and cost. A higher value will allocate more resources to the training process, potentially resulting in higher accuracy but also higher cost.
Another option is the "budget" parameter, which represents the maximum training cost that the user is willing to incur. This parameter allows users to set a hard limit on the cost of training, ensuring that the allocated resources do not exceed the specified budget. The AutoML Tables service will automatically adjust the training process to fit within the specified budget, optimizing the resource allocation to achieve the best possible accuracy within the given constraints.
In addition to these options, AutoML Tables also provides the ability to set a minimum number of model evaluations using the "model_evaluation_count" parameter. This parameter determines the minimum number of times the model should be evaluated during the training process. By setting a higher value, users can ensure that the model is thoroughly evaluated and fine-tuned, potentially leading to better accuracy. However, it is important to note that increasing the number of evaluations will also increase the overall training cost.
Furthermore, AutoML Tables offers the option to specify the desired optimization objective through the "optimization_objective" parameter. This parameter allows users to define the metric they want to optimize during the training process, such as accuracy, precision, recall, or F1 score. By setting the optimization objective, users can guide the training process towards achieving the desired performance goals within the allocated budget.
Lastly, AutoML Tables provides the flexibility to adjust the training budget after the initial training has started. Users can monitor the training progress and make informed decisions based on the intermediate results. If the model is not meeting the desired accuracy within the allocated budget, users can consider increasing the training budget to allocate more resources and improve the model's performance.
To summarize, the options available for setting a training budget in AutoML Tables include the "budget_milli_node_hours" parameter, the "budget" parameter, the "model_evaluation_count" parameter, the "optimization_objective" parameter, and the ability to adjust the budget during the training process. These options provide users with the flexibility to control the resource allocation and optimize the trade-off between model performance and cost.
