Bel Optronic Devices Manual Testing Interview Questions and Answers

Type I error is rejecting a true null hypothesis, while Type II error is failing to reject a false null hypothesis.

• Type I error is also known as a false positive.

• Type II error is also known as a false negative.

• Type I error occurs when the researcher concludes that there is a significant effect when there is not.

• Type II error occurs when the researcher concludes that there is no significant effect when there actually is...read more

Regularization is a technique used to prevent overfitting in machine learning models.

• Regularization adds a penalty term to the loss function to discourage complex models.

• It helps to reduce the variance of the model and improve its generalization performance.

• L1 and L2 regularization are commonly used techniques.

• L1 regularization adds the absolute value of the coefficients to the loss function.

• L2 regularization adds the ...read more

Yes, I have experience conducting census.

• I have conducted a census for a local community organization.

• I was responsible for collecting and analyzing data on population demographics.

• I used various methods such as surveys and interviews to gather information.

• I presented the findings in a comprehensive report to the organization.

IGBT is a voltage-controlled device where the performance is influenced by the voltage across the gate and source.

• IGBT stands for Insulated Gate Bipolar Transistor.

• The voltage across the gate and source controls the conductivity of the IGBT.

• Increasing the gate-source voltage allows more charge carriers to be available, enhancing the device's performance.

• IGBTs are commonly used in power electronics applications due to t...read more
