A batch can go through a series of steps in a large manufacturing process to make the final desired product. [ 1 ] [ 2 ] Batch production is used for many types of manufacturing that may need smaller amounts of production at a time to ensure specific quality standards or changes in the process.
While the descent direction is usually determined from the gradient of the loss function, the learning rate determines how big a step is taken in that direction. A too high learning rate will make the learning jump over minima but a too low learning rate will either take too long to converge or get stuck in an undesirable local minimum.
The batch size refers to the number of work units to be processed within one batch operation. Some examples are: The number of lines from a file to load into a database before committing the transaction. The number of messages to dequeue from a queue.
The disadvantages of planning a small batch are that there will be costs of frequent ordering, and a high risk of interruption of production because of a small product inventory. [12] Somewhere between the large and small batch quantity is the optimal batch quantity, i.e. the quantity in which the cost per product unit is the lowest. [12]
In machine learning, a hyperparameter is a parameter that can be set in order to define any configurable part of a model's learning process. Hyperparameters can be classified as either model hyperparameters (such as the topology and size of a neural network) or algorithm hyperparameters (such as the learning rate and the batch size of an optimizer).
The complexity for steps of this algorithm is (), which is an order of magnitude faster than the corresponding batch learning complexity. The storage requirements at every step i {\displaystyle i} here are to store the matrix Γ i {\displaystyle \Gamma _{i}} , which is constant at O ( d 2 ) {\displaystyle O(d^{2})} .

Steps in a job are executed sequentially, possibly depending on the results of previous steps, particularly in batch processing. The term "job stream" is particularly associated with mainframes; in the IBM z/OS operating system, a job is initiated by a // JOB and terminated by the next // JOB or // statement.
