As we talked about in the previous article, open-mindedness is our ability to view things from a wider perspective, with as few assumptions as humanly possible. We saw how this concept is relevant and useful in a data science project. But how does open-mindedness benefit A.I. in practice?
Just like in the data science case, learning A.I. also stands to benefit from open-mindedness. This is quite obvious, considering how mediocre a job most of the educators of A.I. do and the number of con artists in this field. Keeping an open mind about A.I. and learning it properly are essential for becoming a good A.I. practitioner, particularly one who can see beyond ANNs. After all, there is much more to A.I. than this graph-based family of systems and no matter how good these are, there are always other things to learn such as AI-based optimization methods and Fuzzy Logic systems.
Researching A.I. is probably that case where open-mindedness not only shines but it’s also more or less essential. This is something harder and harder to do since everything in the A.I. research space seems to be geared towards either ANNs or NLP (usually ANN-based). It’s quite rare to find any originality in the A.I. research these days, though a lot of the stochastic optimization systems (which are AI-based optimizers) have some pretty good ideas behind them. Also, some AI-based dimensionality reduction methods are quite interesting too.
Open-mindedness can also be applied when exploring the limits of an A.I. system. This is particularly important in a project since it’s easy to get stuck with the impression that an A.I. system is the best choice, even if it isn’t. Open-mindedness allows you to view other options and consider the limitations of an A.I. system more realistically, making more pragmatic choices.
Finally, open-mindedness as an attitude can help us have a more humble view of things when it comes to A.I. After all, this is a fairly new field (compared to data analytics, for example) and has a lot of room for improvement, something many A.I. practitioners tend to forget. Perhaps that's why many such practitioners are still comparing A.I. models with Stats one (the equivalent of comparing a sports car with a toy car), instead of looking at the various non-AI-based machine learning options, which can be viable alternatives to the project at hand.
In any case, you can learn more about A.I. from an open-minded perspective through a book I have co-authored a couple of years ago. Namely, the AI for Data Science book from Technics Publications covers this subject and provides a variety of stimuli for researching it properly. Although the term open-mindedness is not used per se in this book, it does delve into the way of thinking of an AI-oriented data scientist. So, check it out when you have the chance. Cheers!
Natural Language Processing (NLP) is an essential part of data science today. Although its focus is on analyzing text, its benefits go beyond this and cover cases to improve an existing text. In a world where written communication is becoming more prevalent, this is a powerful aspect of the field. In this article, we'll look into all that through a practical and not-too-technical perspective.
Let’s start with what NLP is. NLP is a specialized field on the overlap of data science and A.I., geared towards analyzing text data, mainly text forming complete sentences. NLP aims to understand things like the tone of the text, its sentiment polarity, and its intention. Specialized aspects of NLP focus on understanding the meaning of the text to provide more in-depth insights regarding it. This kind of NLP is under the Natural Language Understanding (NLU) umbrella, and it's a more advanced aspect of NLP. Other advanced aspects of NLP involve creating new text based on a given text or sometimes even just a prompt.
A given text can improve in various ways. Apart from the apparent corrections (e.g., typos and incomplete sentences), it can be made clearer, less wordy, and more elegant. Changes like these involve improving the vocabulary involved as well as the sentence structure. To automate this process, some NLP work is necessary. Additionally, the user's feedback can be incorporated to enhance the text further, mitigating any inaccurate improvements. What's more, additional improvements from a human editor can be incorporated into the NLP model, even if that editor is the original text's creator. In any case, this is a long process that involves considering various factors, such as the audience the text is targeted at, the objective of the text, etc. That's why to improve a text, you need a systematic and sophisticated approach, one that is versatile enough to adapt and evolve. In short, you need an A.I. system designed for this specific task.
All this may seem like a lot of work for just making a piece of text look nicer, perhaps a bit of an overkill. However, considering the effects of this work, it may be an excellent investment. In particular, by providing suitable corrections to the user (who is also the original text's creator), the latter can improve his writing style and mastery of the language. This is particularly the case when the user is not well versed in linguistics and makes many mistakes. So, this simple NLP pipeline, which is also mostly self-sufficient, can improve the user also, all while enabling her to spend her time on other, more challenging tasks. What's more, a good text can help communication among people, effectively making this NLP work an excellent time-saver for everyone involved in this text.
But where can someone find such an NLP system that can improve a given text and the person who wrote it, eventually? Well, Grammarly has you covered in that regard. This company has developed a powerful A.I. system that does just that, all while having an intuitive and easy-to-use interface that integrates well with your web browser. Having used this system myself for over a year now, I can attest to its usefulness and insightful feedback. Check it out when you have the chance. Cheers!
Cloud Computing is the use of external computing resources for storage and computing tasks via the internet. As for the cloud itself, it's a collection of servers dedicated to this task and are made available, usually through some paid licensing, to anyone with an internet connection. Naturally, these servers are scalable, so you can always increase the storage and computing power you lease from a cloud provider. Although the cloud was initially used for storing data, e.g., for back-up purposes, it's used for various tasks, including data science work.
There are various kinds of machines used for cloud computing, depending on the tasks outsourced to them. For starters, there are the conventional (CPU) servers, used for storing and light computation. Most websites use this cloud computing option, and it's the cheapest alternative for cases where more specialized servers are utilized. However, for small-scale data science projects, especially those employing basic data models, these servers work well.
Additionally, there are the GPU servers that are more affordable for the computational resources they provide. Although GPUs are geared towards graphics-related work (e.g., the rendering of a video), they are well-suited for AI-based models. The latter make use of a lot of computations for the training phase of their function. As more and more data becomes available, this computational cost can only increase. So, having a scalable cloud computing solution that uses this type of server is the optimal strategy for deploying such a model.
Finally, there are also servers with large amounts of RAM, like the regular servers, but with plenty of extra RAM. Such servers are ideal for any use case where lots of data is involved, and it needs to be processed in large chunks. Many data science models fall into this application category since RAM is a valuable resource when large datasets are involved. Multimedia data, in particular, requires lots of memory to be processed at a reasonable speed, even for models that don't need any training.
Cloud computing has started to dominate the data science word lately. This phenomenon is partly due to the use of all-in-one frameworks, which take care of various tasks. These frameworks usually run on the cloud since they require many resources due to the models they build and train. As a result, unless there is a reason for data science work to be undertaken in-house, it is usually outsourced on the cloud. After all, most cloud computing providers ensure high-level encryption throughout the pipeline. The presence of cybersecurity mitigates the risk of data leaks or the compromise of personally identifiable information (PII) that often exists in datasets these days.
A great place that offers cloud computing options for data science is Hostkey. Apart from the conventional servers most hosting companies offer, this one provides GPU servers too. What's more, everything is at a very affordable price tag, making this an ideal solution for the medium- and the long-term. Check out the company's website for more information. Cheers!
