Understanding Machine Learning, Neural Networks and Algorithms

AI is transforming every industry and becoming a phenomenon but it's pretty complicated too. Machine Learning Algorithms, Neural Network etc. how do they work? Here is how!

Well, there are many differences between Machine Learning, Neural Networks, and Machine Learning algorithms. Neural Networks are the subset of Machine Learning algorithms. They are developed because of the integration of algorithmic patterns which are developed with thorough integrations of AI algorithms. Today we’ll discuss these three topics and their interconnectivity that make a chatbot or an AI assistant work.

Machine Learning

Machine Learning usually deals with the “learning” part. It is often misinterpreted that machine learning also understands the context and content of a command but that is NLP’s work. Natural Language Processing (NLP) has the job to “understand” the context and forward it to the ML frameworks. Machine learning is the system by which information is procured through involvement or we can state that Machine Learning is the field that focuses on accepting calculations and and learning those calculations according to the user requirments. Neural system comprises a pool of basic handling units which impart by sending signs to each other over a big number of data patterns.

ML Algorithms

The mainstream pattern of the inner conversations of a chatbot or an assistant powered by Artificial Intelligence is that the NLP understands the context and communicates with the ML framework which allows it to understand it and produce an output, regardless being correct or incorrect. This understanding allows the chatbot to produce outputs in human language and enables the inner Neural Network loops to create a big loop that produces learning algorithms. When the data kicks in and it is transferred to the ML framework, the machine assigns itself an inferred function. This function helps in the analysis and extrapolations of the vague patterns present in the raw data. They layers are also present to analyze the data in an hierarchical way. To extract the hidden layers, supervised and unsupervised learnings were introduced because the hidden layers are a part of neural networks.

Supervised Learning

In supervised learning, input data or training data has a known label or result, like spam or not-spam or a stock price at a time. Preparation of a training process in which predictions are required in a model are made and if the predictions are wrong, they are corrected.

Common problems are the regression and classification. Basic algorithms incorporate Logistic Regression and Back Propagation Neural Network.



Unsupervised Learning

The input data in unsupervised learning is not labeled at all and doesn’t have a known result as well. Deducing structures present in the input data form a model together to extract general rules. It happens through a mathematical process to reduce the redundancy systematically or to organize the data chain by similarity.

The usual problems that occur are the reduction of dimensionality, clustering and association rule learning. The mainstream algorithms are the Apriori algorithm and k-Means.




Neural Networks

The framework is intrinsically parallel as in numerous units can do their calculations in the meantime. Neural Networks are similar to neurons present in our brains, they carry information to place from another. To produce sensible responses, systems may need to incorporate both linguistic context and physical context. In long dialogs, people keep track of what has been said and what information has been exchanged. That’s an example of linguistic context. The most common approach is to embed the conversation into a vector, but doing that with long conversations is challenging.

Neural Network Models and Attention with Intention for a Neural Network Conversation Model both go into that direction. One may also need to incorporate other kinds of contextual data such as date/time, location, or information about a user. Whereas machine Learning deals with both NN (ANN) and other AI techniques. ANN is a subset of Machine Learning strategies which are: non-deterministic (by the academic definition: the NN is only a 'discovery', weights circulation is 'enchantment') and exceedingly parallel (neurons work depends just on their quick environment).



Artificial Neural Network Algorithms

Inspired by the human brain, the Artificial Neural Network Algorithms are deeply interconnected and they even communicate with each other. Each connection marks the exchange or new informations and more learning takes place in each meeting. The previous learning event are not overwritten but edited with the input of new data and repetitive chains are overwritten. The artificial neural networks have many algorithms attached to them but deep learning is the most important one. Here is an example of Deep Learning in the picture below. It is especially known for building much larger complex neural networks.
