Which statement is true about Solution Context when defining large solutions? Causes include increased coordination and integration of disparate work processes and priorities, more dependencies and greater likelihood of unexpressed assumptions. Therefore, assuming any average processing rate, the longer the queue, the longer the wait.

Having your whole team working together means you can talk face-to-face, facilitating small batch communication with real-time feedback and clarification. The economically optimal batch size depends on both the holding cost (the cost for delayed feedback, inventory decay, and delayed value delivery) and the transaction cost (the cost of preparing and implementing the batch). Usually, we chose the batch size as a power of two, in the range between 16 and 512. The batch size affects some indicators such as overall training time, training time per epoch, quality of the model, and similar. Small batches go through the system faster and with less variability than larger batches.

A. you know that training a deep learning model that has a lot of parameters has a relation to CPU obviously, for practical guidelines especially from an academic perspective, there is that tradeoff between accuracy and computational resources. The alternative is to have a single cross-functional, multi-disciplinary team and work on all the layers of a tightly-focussed piece of functionality. These three primary mechanisms for implementing flowvisualizing and limiting WIP, reducing the batch sizes of work, and managing queue lengthsincrease throughput and accelerate value delivery. Analysing the economics of batch size, however, reveals that these economies are significantly outweighed by the benefits of reducing batch size. We can facilitate this by setting up a DevOps environment that integrates development and IT operations. Lets get started.
