What is Machine Learning?
Machine learning is a subset of Artificial Intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it to learn for themselves.
The learning process begins with observations or data, such as examples, direct experience, or instruction, to look for patterns in data and make better decisions in the future based on the examples we provide. The primary aim is to allow the computers to learn automatically without human intervention or assistance and adjust actions accordingly.
What Are ML Algorithms?
Machine learning algorithms are computer algorithms that learn from data and improve their performance over time without being explicitly programmed. These algorithms can identify patterns in data, detect anomalies, and make predictions. Examples of ML algorithms include decision trees, random forests, support vector machines, and neural networks.
Step for Data Preprocessing
Binarization
Binarization is the process of converting data into a binary format. This is usually done to make data easier to store and process by computers. Binarization involves converting numerical or categorical data into a binary format in which each value is represented as either a 0 or a 1. For instance, a categorical variable with three possible values (e.g., high, medium, low) might be converted into a binary format that would represent each value as either 0 (low), 1 (medium), or 2 (high).
Step 1. Import Num library as a name “np” and import preprocessing function from sklearn.
Step 2. Create a NumPy array for sample data.
Step 3. Binarization Output
To binarize the data, use preprocessing.Binaries(). This function binarizes data according to an imposed threshold. Values greater than the threshold map to 1, while values less than or equal to the threshold map to 0. With the default threshold of 0, only positive values map to 1. In our case, the threshold imposed is 1.4, so values greater than 1.4 are mapped to 1, while values less than 1.4 are mapped to 0.
Output:
(II) Standard Deviation: Standard Deviation is a measure of the spread or dispersion of a set of data values. It is calculated as the square root of the variance of the data. It is used to measure how much variation or dispersion exists from the average (mean) of the data set.
Step 4. Now, find out the mean and standard deviation value for input data.
Output:
Mean removal technique
Mean Removal is a data preprocessing technique in Data Science which involves subtracting the mean value from each data point in a dataset. This is done to centre all the data around zero, which can be useful when training a model. The mean value is calculated by taking the average of all data points in the dataset. This technique is useful for removing the mean from our feature vector so that each feature is centered on zero. This is done to remove bias from the features in the feature vector.
Step 5. To do mean removal in input data, use the use scale function.
Output:
Step 6. Now map or scale the values according to the minimum and maximum values of the input data.
Scaling
Data Scaling is a process used to normalize the range of independent variables in order to make sure that the data points can be treated equally. It is also used to bring all the data points to the same level of magnitude which helps in faster processing and better performance of the data models. Scaling helps in many ways such as it avoids bias, improves accuracy, improves convergence speed when training a model, and also makes it easier to compare different data points.
Output:
Step 7. Now, use normalization technique to modify the values in the feature vector so that we can measure them on a common scale. In Machine learning, we use many different forms of normalization. Some of the most common forms of normalization aim to modify the values so that they sum up to 1.
Label Encoding: When we perform classification, we usually deal with a lot of labels. These labels can be in the form of words, numbers, or something else. The machine learning functions in sklearn expect them to be numbered. So, if they are already numbers, we can use them directly to start training. But this is not usually the case.
Step 8: Create one list for colors with input_labels variable.
Step 9. Now, map labels into numerical values according to order.
Output:
Step 10. Encode labels values using encoder.transform function.
Output:
Step 11. Now, inverse these encoded values to label.
Output:

Coding is generally considered a boring activity. After all, who wants to sit in front of a computer all day writing in a language that can’t even be read? But that is not all there is to code. It can be used for some really fun coding facts stuff, and there is so much amazing work that you can do only if you knew how to code.
5 Coding Facts That Blow Your Mind
Let us look at five great fun coding facts you might not know about coding.
You Can Make Games With Code
Coding is an umbrella term for the scores of languages and their versions that programmers use to make their applications. We have all played games, on consoles, our mobile phones, or our desktop computers and laptops, at some point in our life. It might not surprise you to know that these games are also created using code. The complex physics of the characters in these games, the design of the environment of the games, and each minute movement in the games have a piece of code behind them.
Game designers typically write in languages such as C++, C#, and Java. These are also some of the most popular kids coding languages, especially for children who like gaming. Coding courses are available widely in all of these languages and the broad domain of game design.
You Do Better At School If You Code
Making games and indulging in the fun applications of coding is all fine, but coding can have great advantages at school as well. Once you start taking classes that teach coding for kids, you will realize that coding requires a lot of brainpower as well. Coding even for the most fun tasks requires you to think quite a bit, and this sharpens your mind and increases your capability to think logically.
This logical capability can be of a lot of use to you at school. Especially in subjects like mathematics, you might find yourself topping the class simply because of the practice you got during coding! In fact, coding and mathematics have a kind of symbiotic relationship – what you learn in maths comes of use in code and vice versa.
