Which image classification technique involves using a pre-trained model and fine-tuning it on a new dataset?

Back

Transfer Learning

Answer explanation

Transfer Learning is the technique that uses a pre-trained model and fine-tunes it on a new dataset, making it efficient for image classification tasks. This approach leverages existing knowledge to improve performance on new data.

What is the strategic importance of tokenization in text preprocessing for NLP tasks?

Back

It converts text into a format that can be easily processed by machine learning models.

Answer explanation

Tokenization is crucial as it converts text into a structured format, such as tokens, that machine learning models can easily process. This step is essential for enabling further analysis and understanding of the text data.

In deploying a vision model, what strategic considerations should be made to ensure the model's performance in a real-world environment?

Back

Optimizing the model for low latency and high throughput

Answer explanation

Optimizing the model for low latency and high throughput is crucial for real-world deployment, as it ensures quick responses and efficient processing, which are essential for user satisfaction and operational effectiveness.

How does transfer learning strategically benefit the development of AI models in resource-constrained environments?

Back

It reduces the need for extensive computational resources

Answer explanation

Transfer learning reduces the need for extensive computational resources by leveraging pre-trained models, allowing for effective training even with limited data and hardware, which is crucial in resource-constrained environments.

Front

What is the strategic role of cross-validation in evaluating NLP models?

Back

It provides a robust estimate of the model's performance

Answer explanation

Cross-validation provides a robust estimate of a model's performance by evaluating it on multiple subsets of data, ensuring that the results are reliable and not dependent on a single train-test split.

Front

Which image classification technique is strategically used to handle class imbalance in datasets?

Back

Data Augmentation

Answer explanation

Data Augmentation is used to artificially increase the size of the minority class in imbalanced datasets by creating modified versions of existing images, helping to improve model performance and generalization.

Front

What strategic planning is involved in selecting text preprocessing methods for a sentiment analysis task?

Back

Retaining negations and emoticons

Answer explanation

Retaining negations and emoticons is crucial in sentiment analysis as they convey important emotional context. Removing them could lead to misinterpretation of sentiments, making this choice strategically vital for accurate analysis.

Front

In vision model deployment, what strategic factors should be considered to ensure scalability?

Back

Using cloud-based services for deployment

Answer explanation

Using cloud-based services for deployment ensures scalability by providing flexible resources that can handle varying loads, allowing the model to grow with demand without the need for significant infrastructure investment.
