Neural Networks: The Brain-Inspired Tech Behind AI

Posted on by nullplex

Neural networks are a fascinating concept in the world of artificial intelligence (AI). They’re essentially computer programs inspired by the structure and function of the human brain, allowing machines to learn and process information in a way that’s more human-like than traditional programming.

Imagine this: You show a child pictures of cats and dogs. Over time, the child learns to distinguish between the two animals. A neural network does something similar but with much more data and much faster processing power.

So, how do these brain-inspired programs work?

  • Think of neurons: In the brain, neurons are cells that communicate with each other through electrical signals. In a neural network, these neurons are represented by mathematical functions called “nodes.”
  • Nodes are connected: Just like neurons have axons and dendrites, nodes in a neural network are connected by “weights.” These weights determine the strength of the signal passing between nodes.
  • Learning through layers: Neural networks are typically organized in layers. Information flows from the input layer (think of it as your eyes or ears) through hidden layers (where the processing happens) to the output layer (your voice or actions).
  • Adjusting the weights: As the network processes data, the weights between nodes are adjusted based on the results. This is like how the brain strengthens or weakens connections between neurons based on experience.

What can neural networks do?

  • Recognize patterns: They’re great at identifying patterns in data, like images, speech, or text. This makes them useful for tasks like image recognition, voice assistants, and machine translation.
  • Make predictions: Based on what they’ve learned, neural networks can make predictions about future events or data. This is used in weather forecasting, stock market analysis, and fraud detection.
  • Adapt and learn: Unlike traditional programs, neural networks can continuously learn and improve as they’re exposed to more data. This makes them incredibly versatile and powerful.

Neural networks are still under development, but they’re already revolutionizing many fields. From healthcare and finance to self-driving cars and virtual assistants, the possibilities are endless.

Here are some things to keep in mind about neural networks:

  • They can be complex: Building and training neural networks can be computationally expensive and require specialized expertise.
  • They need data: The more data a neural network is trained on, the better it will perform.
  • They can be biased: If the data used to train a network is biased, the network will reflect that bias.

Overall, neural networks are a powerful tool with the potential to change the world. As they continue to evolve, we can expect even more incredible applications in the years to come.

Call, Apply, Bind – Understanding Basic Concepts of JavaScript

Posted on by nullplex

In programming languages, you have a this keyword. The “this” keyword lets you refer to an object from within that object. “this”‘s value will change depending on the context that “this” is called in. By default it refers to the global scope, but when called within a function, it refers to that function.

Note – To understand call, apply, and bind you need to have good knowledge of how “this” works in JavaScript.

call(), apply(), and bind() can refer “this” to object.

 This let’s you to change the context of this when you invoke the function. It depends on how we are invoking the function.

1) Call:

Call method takes input as an String args comma seperated. call() provides a new value of this to the function/method. With call(), you can write a method once and then inherit it in another object, without having to rewrite the method for the new object.

                ex –

                const commonMethods = {

    fullname : function(city,state){

        return this.fname + ” ” + this.lname + ” Lives in ” + city + ” – ” + state;

    }

                }

                const Hero_1 = {

                    fname : “Tony”,

                    lname : “Stark”

                };

                const Hero_2 = {

                    fname : “Steve”,

                    lname : “Rogers”

                }

                const Hero_1_Details = commonMethods.fullname.call(Hero_1,”Malibu Point”,”USA”);

                const Hero_2_Details = commonMethods.fullname.call(Hero_2,”Washington, D.C.”,”USA”);

                console.log(Hero_1_Details);

                console.log(Hero_2_Details);



2) Apply:

It is same as call but different in passing the arguments in. The apply() method calls the specified function with a given this value, and arguments provided as an array (or an array-like object). apply() accepts a single array of arguments — for example, func.apply(this, [‘eat’, ‘bananas’]);

                ex :

                                const commonMethods = {

    fullname : function(city,state){

        return this.fname + ” ” + this.lname + ” Lives in ” + city + ” – ” + state;

    }

                }

                const Hero_1 = {

                    fname : “Tony”,

                    lname : “Stark”

                };

                const Hero_2 = {

                    fname : “Steve”,

                    lname : “Rogers”

                }

                const Hero_1_Details = commonMethods.fullname.apply(Hero_1,[“Malibu Point”,”USA”]);

                const Hero_2_Details = commonMethods.fullname.apply(Hero_2,[“Washington, D.C.”,”USA”]);

                console.log(Hero_1_Details);

                console.log(Hero_2_Details);

 



3) Bind:

The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called. With the bind() method, an object can borrow a method from another object.

                const Hero_1 = {

                    fname : “Tony”,

                    lname : “Stark”,

                    fullname : function(city,state){

                        return this.fname + ” ” + this.lname + ” Lives in ” + city + ” – ” + state;

                    }

                };

                const Hero_2 = {

                    fname : “Steve”,

                    lname : “Rogers”,

                    showSuperPower : function(power){

                        return `Super Power is ${power}`

                    }

                }

                // here we have interchanged the function of each other. (showSuperPower and fullname)

                const Hero_2_Details = Hero_1.fullname.bind(Hero_2);

                console.log(Hero_2_Details(“Washington, D.C.”,”USA”));

                // Or

                const Hero_1_Details = Hero_2.showSuperPower.bind(Hero_1);

                console.log(Hero_1.fullname(“Malibu Point”,”USA”) + ” – and ” +Hero_1_Details(“Can Fly”));



Pros of using call apply bind:

  1. Code duplication removed.
  2. We can create a new function and bind with existing.
  3. Readability improves.

Cons of using call apply bind:

Basic concepts of Scops and “this” keyword must be strong else find hard to read and debug
