Learning from the Master: Using ChatGPT for Reinforcement Learning - part 2 - Solita Data

#artificialintelligence

In the first part of this series, we explored the capabilities of ChatGPT, a state-of-the-art language model developed by OpenAI, in assisting data scientists with tasks such as data cleaning, preprocessing, and code generation. In this second part, we will delve deeper into what ChatGPT generated and why it didn't work. We will discuss the specific challenges that come with using AI-generated code, and how to effectively address these issues to ensure the reliability and accuracy of the final product. Whether you're a data scientist or a developer, this post will provide valuable insights into how to use ChatGPT to improve your workflow and streamline your development process.

Modeling Recommendation Systems as Reinforcement Learning Problem

#artificialintelligence

In this era, a massive volume of information is available to the users through web which leads to information overload. The Recommender systems are used to facilitate the search through this vast space of items by giving user personalised services and items. The vast majority of traditional recommendation systems consider the recommendation procedure as a static process and make recom- mendations following a fixed strategy. A user interacts with recommendation engine in a sequence of exchanges of recommendations and provides feedback on them. Hence, we should also try to incorporate the feedback ofthe user at each time step while recommending items at the next time step.

Language models have shown impressive capabilities in the past few years by generating diverse and compelling text from human input prompts. However, what makes a "good" text is inherently hard to define as it is subjective and context dependent. There are many applications such as writing stories where you want creativity, pieces of informative text which should be truthful, or code snippets that we want to be executable. Writing a loss function to capture these attributes seems intractable and most language models are still trained with a simple next token prediction loss (e.g. To compensate for the shortcomings of the loss itself people define metrics that are designed to better capture human preferences such as BLEU or ROUGE.


The Best Resources to Learn Reinforcement Learning

#artificialintelligence

Reinforcement learning (RL) is a paradigm of AI methodologies in which an agent learns to interact with its environment in order to maximize the expectation of reward signals received from its environment. Unlike supervised learning, in which the agent is given labeled examples and learns to predict an output based on input, RL involves the agent actively taking actions in its environment and receiving feedback in the form of rewards or punishments. This feedback is used to adjust the agent's behavior and improve its performance over time. RL has been applied to a wide range of domains, including robotics, natural language processing, and finance. In the gaming industry, RL has been used to develop advanced game-playing agents, such as the AlphaGo [1] algorithm that defeated a human champion in the board game Go.


6 Reasons to Migrate to Reinforcement Learning

#artificialintelligence

Reinforcement Learning (RL) and Supervised Learning (SL) are two popular machine learning techniques. Both have their own advantages and disadvantages. In summary, both RL and SL have their own advantages and disadvantages. RL is well-suited for handling complex and dynamic environments, while SL is simpler to implement and understand, and can handle large amounts of data. The choice of method will depend on the specific task and the resources available.

Reinforcement learning and its applications

#artificialintelligence

Reinforcement Learning (RL) is a type of machine learning that focuses on training agents to make decisions in an environment by maximizing a reward signal. It differs from supervised learning, where the agent is given a labeled dataset to learn from, and unsupervised learning, where the agent is given an unlabeled dataset to find patterns on its own. In RL, the agent learns by interacting with the environment and receiving feedback in the form of rewards or penalties. One of the most popular applications of RL is in the field of gaming. RL algorithms have been used to train agents to play a wide range of games, from simple arcade games to complex strategy games such as Go and chess.


Reinforcement Learning in Finance

#artificialintelligence

The main goal of this specialization is to provide the knowledge and practical skills necessary to develop a strong foundation on core paradigms and algorithms of machine learning (ML), with a particular focus on applications of ML to various practical problems in Finance. The specialization aims at helping students to be able to solve practical ML-amenable problems that they may encounter in real life that include: (1) mapping the problem on a general landscape of available ML methods, (2) choosing particular ML approach(es) that would be most appropriate for resolving the problem, and (3) successfully implementing a solution, and assessing its performance. The specialization is designed for three categories of students: · Practitioners working at financial institutions such as banks, asset management firms or hedge funds · Individuals interested in applications of ML for personal day trading · Current full-time students pursuing a degree in Finance, Statistics, Computer Science, Mathematics, Physics, Engineering or other related disciplines who want to learn about practical applications of ML in Finance. The modules can also be taken individually to improve relevant skills in a particular area of applications of ML to finance.


9 awesome real world applications of Reinforcement Learning

#artificialintelligence

Reinforcement Learning is a framework for sequential decision making. It differs from the usual supervised setting as there are no labels present. In this framework an'agent' interacts with an'environment' to gain experience from which the agent learns to perform the most optimal action which maximises its rewards. Reinforcement Learning has had major advances in the last few years and is being applied to real world problems. The pace of adoption has definitely been slower than other ML approaches as RL has its own challenges.
