Also, Non-symbolic AI systems generally depend on formally defined mathematical optimization tools and concepts. That involves modeling the whole problem statement in terms of an optimization problem.

However, many real-world AI problems cannot or should not be modeled in terms of an optimization problem. So, it is pretty clear that symbolic representation is still required in the field. However, as it can be inferred, where and when the symbolic representation is used, is dependant on the problem. Another example is games like Chess, which require syntactic representations of the current board state, what each piece is and what it can do, to make appropriate decisions for a follow-up move.
Toward artificial intelligence that learns to write code
Therefore, it seems pretty important to understand that when we have sufficient information about the players and actors in the environment of a specialized high-level skilled intelligent system, it becomes more important to utilize a symbolic representation rather than a non-symbolic one.
However, what might be even more exciting, is the integration of symbolic and non-symbolic representations. They can help each other to reach an overarching representation of the raw data, as well as the abstract concepts this raw data contains. For example, we may use a non-symbolic AI system Computer Vision using an image of a chess piece to generate a symbolic representation telling us what the chess piece is and where it is on the board or used to understand the current attributes of the board state.
In short, analogous to humans, the non-symbolic representation based system can act as the eyes with the visual cortex and the symbolic system can act as the logical, problem-solving part of the human brain.

Implementation of supervised learning runs into a number of deep problems, including long training times and human-induced bias in construction of datasets. But if you throw a dog photo into the mix and ask the algorithm to find it, your AI might be in trouble. Still, these algorithms are widely used in applications including chatbots, facial recognition and information retrieval.
Unlike our cat example, where users teach the algorithm by exposing it to known information, unsupervised learning systems go in completely blind.

By comparing values within its training dataset, the algorithm builds models to explain relationships among those data points. Unsupervised learning is useful for revealing relationships and structures within data that may not be immediately obvious, especially in huge, disorganized datasets.
For example, an algorithm might be shown many sets of images of people in the moments before they committed a crime. By identifying and sorting subtle patterns it finds within those images, such an AI could predict the probability of a similar attack occurring in similar circumstances. Just as a lab rat may learn to prefer one lever because it delivers a snack and to avoid another because it delivers a shock, reinforcement learning for artificially intelligent agents relies on rewards.
Unlike supervised and unsupervised learning, reinforcement learning algorithms receive no guidance for what the rules of a system are or what data it might contain. A reinforcement learning algorithm continually tests and evaluates the results of its actions to learn what constitutes success and failure; then it works to maximize successful pathways. The technique also shows great promise in helping self-driving vehicles become even better at navigating and avoiding collisions and other errors.

What Is an Algorithm, Anyway? If this is correct, then a key objective for deep learning is to develop architectures capable of discovering objects and relations in raw data, and learning how to represent them in ways that are useful for downstream processing.
