The one difference between a man and his machines has always been the decision-making ability possessed by the living species. Machines on other grounds have surpassed humans such as intelligence, speed and memory but in the end, it would be a human who would approve of the machine’s work.
Enter Machine learning tools; these are tools that allow the machines to make predictions about data on its own using the previous usage of the same data. This power allows the machines to bridge their gap between them and humans.
Machine Learning is the practice of using ML algorithms to decipher data and learn from it, and then make predictions using the acquired knowledge. It is the process of making the machines efficient enough so that it becomes ‘artificially intelligent’ and processes the given data just by keeping previous tasks in its memory without using any extensive coding routines.
Until the introduction of AI, the coders mostly steered the task of churning hand-written classifiers for the machines to make sense out of data.
The algorithms were good and made the processing uncomplicated but there’s a reason computer vision and image detection didn’t come close to rivalling humans until very recently, it was too brittle and too prone to error.
The basic motive of machine learning is to give training data to a learning algorithm. The learning algorithm then generates a new set of rules, based on inferences from the given data. This is in essence generating a new algorithm, earlier referred to as the machine learning model.
By using diverse training data, the same learning algorithm could be used to generate different models. For example, the same type of learning algorithm could be used to teach the computer how to translate pictures into speeches or predict the stock market.
Machine learning is not a new concept. Many of the learning techniques are based on decade long research. The current growth in AI and machine learning relies on developments in three important areas:
Data Availability- As the consumption of data has increased leaps and bounds and combined with the decreased costs of storage, it forms a perfect breeding ground for machines to learn algorithms using this training data.
Powerful computers- With the new advanced computers coming into play, it has made the processing of enormous data seem like a piece of cake.
Algorithmic innovation- New machine learning techniques, specifically in layered neural networks termed as “deep learning” have inspired new services, but are also igniting investments and research in other parts of the field.
Algorithms play a very predominant role in learning. There are four sorts of machine learning algorithms: supervised, unsupervised, semi-supervised, and reinforced:
Supervised algorithms are machine learning tools that act as students as they are supervised in the learning process till the algorithms become self-sufficient.
Unsupervised algorithms require little or no human interaction as they use an approach called “deep learning” to review data and reach conclusions supporting previous samples of training data.
Semi-supervised algorithms tend to fall within the middle ground and are a combination of both supervised and unsupervised algorithms.
Reinforced algorithms force models to repeat a process until it produces the foremost favourable outcomes. Attempts that produce these favourable outcomes are rewarded and the ones that produce unfavourable results are penalized until the algorithm learns the optimal process.
Now just to make this concept crystal clear, here are few real-life examples of Machine Learning:
Example 1- If you have used Netflix, then you would be aware that it recommends you some movies or shows for watching based on what you have watched earlier. Machine Learning is used for this practice and to select the data which matches your choice.
Example 2- The second example is Software-processing, which shows how you will look when you get older. This image processing also uses the expertise of machine learning.

Machine learning tools are algorithmic applications of AI that give systems the power to find out and improve without extra human input; similar concepts are data processing and predictive modelling. They allow software to become more precise in predicting outcomes without being explicitly programmed.
The idea is that a model or algorithm is appointed to gather data from the planet, which data is reversed back to the model in order that it improves over time. It’s called machine learning because the model “learns” because it is fed more and more data.
They can be used, for instance, to create recommendation engines, predict search patterns, filter spam, build news feeds, detect threats and security frauds.

Scikit-learn is used for machine learning development in python. It provides a library for the Python programming language and is built upon some of the technology, namely, NumPy, pandas, SciPy and Matplotlib.
The name Scikit comes from SciPy as modules of SciPy are known as scikit and the modules provide learning algorithms, hence the word ``learn''.
Although the interface is Python, c-libraries are utilized for performance such as NumPy for arrays and matrix operations, LAPACK, LibSVM and the careful use of cython.

Waikato Environment for Knowledge Analysis (WEKA), developed at the University of Waikato, New Zealand, is a free software licensed under the GNU General Public License for data mining.
These algorithms can either be applied directly to a dataset or called from your own Java code. It is also well-suited for developing new machine learning schemes.
Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It can be considered more of an educational tool rather than an industrial tool because it provides a great learning path for beginners.
