Why do we need to learn ?

AI can impact every aspect of our lives. the sector of AI tries to know patterns and behaviors of entities. With AI, we would like to create smart systems and understand the concept of intelligence also . The intelligent systems that we construct are very useful in understanding how an intelligent system like our brain goes about constructing another intelligent system.

Let’s look at how our brain processes information:
basic brain component
Compared to another fields like mathematics or physics that are around for hundreds of years , AI is comparatively in its infancy. Over the last few decades, AI has produced some spectacular products like self-driving cars and intelligent robots which will walk. supported the direction during which we are heading, it’s obvious that achieving intelligence will have an excellent impact on our lives within the coming years.

We can’t help but wonder how the human brain manages to try to to such a lot with such effortless ease. we will recognize objects, understand languages, learn new things, and perform more sophisticated tasks with our brain. How does the human brain do this? we do not yet have many answers thereto question. once you attempt to replicate tasks that the brain performs, employing a machine, you’ll see that it falls way behind! Our own brains are much more complex and capable than machines, in many respects.

When we attempt to search for things like extraterrestrial life or time travel, we don’t know if those things exist; we’re unsure if these pursuits are worthwhile. The good thing about AI is that an idealized model for it already exists: our brain is that the holy grail of an intelligent system! All we have to do is to mimic its functionality to create an intelligent system that can do something similarly to, or better than, our brain.

Let’s see how raw data gets converted into intelligence through various levels of processing:
data into intelligence
One of the most reasons we would like to review AI is to automate many things. We live in a world where:

  • We affect huge and insurmountable amounts of knowledge . The human brain can’t keep track of so much data.
  • Data originates from multiple sources simultaneously. The data is unorganized and chaotic.
  • Knowledge derived from this data must be updated constantly because the data itself keeps changing.
  • The sensing and actuation must happen in real-time with high precision.
Even though the human brain is great at analyzing things around us, it cannot keep up with the preceding conditions. Hence, we need to design and develop intelligent machines that can do this. We need AI systems that can:
  • Handle large amounts of knowledge in an efficient way. With the advent of Cloud Computing, we are now ready to store huge amounts of knowledge.
  • Ingest data simultaneously from multiple sources without any lag. Index and organize data in a way that allows us to derive insights.
  • Learn from new data and update constantly using the right learning algorithms. Think and respond to situations based on the conditions in real time.
  • Continue with tasks without getting tired or needing breaks.
AI techniques are actively being used to make existing machines smarter so that they can execute faster and more efficiently.

Branches of
AI, Artificial Intelligence

It is important to know the varied fields of study within AI in order that we will choose the proper framework to unravel a given real-world problem. There are several ways to classify the different branches of AI:
  • Supervised learning vs. unsupervised learning vs. reinforcement learning
  • Artificial general intelligence vs. narrow intelligence
  • By human function:
  1. Machine vision
  2. Machine learning
  3. Natural language processing
  4. Natural language generation
Following, we present a common classification:
  • Machine learning and pattern recognition: this is often perhaps the foremost popular form of AI out there. We design and develop software which will learn from data. supported these learning models, we perform predictions on unknown data. one among the most constraints here is that these programs are limited to the power of the data.
If the dataset is little , then the training models would be limited also . Let’s see what a typical machine learning system looks like:
computer system
When a system receives a previously unseen datum , it uses the patterns from previously seen data (the training data) to form inferences on this new data point. for instance , during a face recognition system, the software will try to match the pattern of eyes, nose, lips, eyebrows, then on so as to seek out a face within the existing database of users.
  • Logic-based AI: symbolic logic is employed to execute computer programs in logic-based AI. A program written in logic-based AI is essentially a group of statements in logical form that expresses facts and rules a few problem domain. this is often used extensively in pattern matching, language parsing, semantic analysis, and so on.
  • Search: Search techniques are used extensively in AI programs. These programs examine many possibilities then pick the foremost optimal path. For example, this is often used tons in strategy games like chess, networking, resource allocation, scheduling, and so on.
  • Knowledge representation: The facts about the planet around us got to be represented in how for a system to form sense of them. The languages of symbolic logic are frequently used here. If knowledge is represented efficiently, systems are often smarter and more intelligent. Ontology may be a closely related field of study that deals with the sorts of objects that exist.
  • Planning: This field deals with optimal planning that provides us maximum returns with minimal costs. These software programs start with facts about the situation and a press release of a goal. These programs also are aware of the facts of the planet , in order that they know what the principles are. From this information, they generate the foremost optimal decide to achieve the goal.
  • Heuristics: A heuristic may be a technique wont to solve a given problem that’s practical and useful in solving the matter within the short term, but not guaranteed to be optimal. this is often more like an informed guess on what approach we should always fancy solve a drag . In AI, we often encounter situations where we cannot check every single possibility to select the simplest option. Thus, we’d like to use heuristics to realize the goal. they’re used extensively in AI in fields like robotics, search engines, and so on.
  • Genetic programming: Genetic programming may be a thanks to get programs to solve a task by mating programs and selecting the fittest. The programs are encoded as a group of genes, using an algorithm to urge a program which will perform the given task well.
