Multiple elements can be stored in a single variable using a tuple. Tuple is one of Python's four built-in data types for storing collections of data; the other three are List, Set, and Dictionary, all of which have different properties and applications. A tuple functions in python is a collection of items that is both ordered and immutable. Tuple Items Tuple elements are immutable, sorted, and allow for duplicate values.The first item has an index of [0], the second item has an index of [1], and so on. Ordered When we state that tuples are sorted, we're referring to the fact that the items are in a specific sequence that will not change. Unchangeable Tuples are immutable, which means we can't edit, add, or remove things after they've been generated. Allow Duplicate Tuples can have items with the same value since they are indexed: Duplicate values are allowed in example tuples: thistuple = ("apple," "banana," "cherry," "apple," &

With a difference in output range of -1 to 1, the tanh activation function is remarkably similar to the sigmoid/logistic activation function, and even has the same S-shape. The larger the input (more positive), the closer the output to 1.0, and the smaller the input (more negative), the closer the output to -1.0. Mathematically it can be represented as: The following are some of the benefits of using this activation function: We can simply map the output values as strongly negative, neutral, or very positive because the tanh activation function's output is Zero centred. Because its values range from -1 to, it's commonly utilised in hidden layers of neural networks. As a result, the hidden layer's mean is 0 or extremely close to it. It aids in data centering and makes learning the next layer much simpler. To understand the tanh activation function's limits, look at its gradient. As you can see, it, like the sigmoid activation function, has the problem of vanishing gradi
