how to use AlphaCode

• AlphaCode is an AI system that translates problem descriptions into code.
• Researchers fed a large language model with gigabytes of code from GitHub to familiarize it with coding syntax and conventions.
• AlphaCode was trained to translate problem descriptions into code using thousands of problems collected from programming competitions.
• AlphaCode generates candidate code solutions (in Python or C++) and filters out the bad ones.
• Researchers trained AlphaCode to generate up to more than 1 million candidates.
• AlphaCode keeps only the 1% of programs that pass test cases that accompany problems and clusters the keepers based on the similarity of their outputs to made-up inputs.
• AlphaCode submits programs from each cluster, one by one, starting with the largest cluster, until it alights on a successful one or reaches 10 submissions.
• AlphaCode solved about 34% of the assigned problems, which is higher than similar benchmarks such as Codex.
• DeepMind entered AlphaCode into online coding competitions. In contests with at least 5000 participants, the system outperformed 45.7% of programmers.
• AlphaCode requires computing power that only the largest tech companies have, as it requires tens of billions of trillions of operations per problem.
• Researchers want to reduce the system’s errors, as AlphaCode sometimes makes simple mistakes, such as creating a variable and not using it.
• The study noted the long-term risk of software that recursively improves itself, which could lead to a superintelligent AI that takes over the world.
• AI coding might have applications beyond winning competitions, freeing up developers to work at a higher, or more abstract level, or it could help noncoders create simple programs.
• Researchers urged the field of AI coding to institute guardrails, built-in checks, and balances even if this kind of technology becomes supersuccessful, to treat it the same way an organization treats a programmer within an organization where a single programmer could bring the entire organization down.
• Wojciech Zaremba, a co-founder of OpenAI, called the results of AlphaCode “stunning.”
• AI coding or similar technology could help developers to better understand code. For instance, AlphaCode could run in reverse, translating code into explanations of what it’s doing, which could benefit programmers trying to understand others’ code.
• A global shortage of programmers has been identified, and an AI system such as AlphaCode might someday assist experienced coders, but probably cannot replace them.
• GPT-3, a “large language model”

• DeepMind has created a system called AlphaCode that is capable of writing computer programs at a competitive level and solving new problems that require a combination of critical thinking, logic, algorithms, coding, and natural language understanding.
• AlphaCode achieved an estimated rank within the top 54% of participants in programming competitions by combining advances in large-scale transformer models (that have recently shown promising abilities to generate code) with large-scale sampling and filtering.
• The machine learning community has made tremendous progress in generating and understanding textual data; however, advances in problem-solving remain limited to relatively simple maths and programming problems or retrieving and copying existing solutions.
• AlphaCode uses transformer-based language models to generate code at an unprecedented scale, and then smartly filters to a small set of promising programs.
• They have validated their performance on Codeforces, a popular platform that hosts regular competitions that attract tens of thousands of participants from around the world. They selected for evaluation 10 recent contests, each newer than their training data. AlphaCode placed at about the level of the median competitor, marking the first time an AI code generation system has reached a competitive level of performance in programming competitions.
• Even though the problem-solving abilities required to excel at these competitions are beyond the capabilities of existing AI systems, they made significant progress in the number of problems they can solve by pre-training their model on selected public GitHub code and fine-tuning it on their relatively small competitive programming dataset.
• They created a massive amount of C++ and Python programs for each problem at the evaluation time, orders of magnitude larger than previous work. Then they filtered, clustered, and reranked those solutions to a small set of 10 candidate programs that they submitted for external assessment. This automated system replaces competitors’ trial-and-error process of debugging, compiling, passing tests, and eventually submitting.
• They hope that this benchmark will lead to further innovations in problem solving and code generation. To help others build on their results, they have released their dataset of competitive programming problems and solutions on GitHub, including extensive tests to ensure the programs that pass these tests are correct — a critical feature current datasets lack.
• Competitive programming is a popular and challenging activity worldwide, with hundreds of thousands of programmers participating in coding competitions to gain experience and showcase their skills in fun and collaborative ways. During competitions, participants receive a series of long problem descriptions and a few hours to write programs to solve them.
• Companies use these competitions as recruiting tools, and similar types of problems are common in hiring processes for software engineers.
• The impressive work

• Deepmind introduces AlphaCode, a code generation system that uses large-scale language models for solving competitive programming problems.
• Competitive programming tasks support the general-purpose problem-solving tool aspect of computer programming difficult to incorporate AI breakthroughs to develop systems making programming more accessible and efficient.
• AlphaCode provides automated coding solutions to make developer teams more productive.
• The more difficult programming problems need problem-solving skills beyond translating instructions into code.
• AlphaCode uses large scale transformer models for code generation. They use the self-attention mechanism that makes them proficient in processing groups of long-range dependencies among the input tokens.
• The transformer model used in AlphaCode combines self-supervised learning and supervised learning to enhance performance on competitive programming tasks. They use a model trained through self-supervised adaptation on unsupervised data followed by finetuning on supervised data.
• The research paper “Competition-Level Code Generation with AlphaCode” explains the details of AlphaCode’s architecture and how they fine-tuned the model while achieving high ranking on various online competitive programming platforms.
• In addition to the paper, there is a blog post, “Competitive Programming with AlphaCode,” on DeepMind’s website that explains the background behind the invention and how it raises the bar for automated code generation.
• AlphaCode can synthesize a loop that has the same general behavior understood by a human when presented with an input-output pair.
• It is challenging for language models to create code that performs a specified goal since it requires searching through the large structured program space. It necessitates a trying combination of multiple tokens to encode the problem’s input, make the necessary transition between the input and output spaces, and finally, the output code to match the functional properties of the problem statement.
• AlphaCode considers the cumulative reward of each generating code in multiple stages as a result of searching through multiple subtrees of the possible code generation sequence.

• AlphaCode generates a lot of programs using transformer neural network and doubles the variety by generating code in both Python and C++
• In addition to random sampling, AlphaCode randomly attaches a tag to the task description and a (random) number indicating a supposed problem’s complexity.
• Another neural network generates new test inputs by looking only at the examples in the task specification and does not seek to “understand” the problem much less solve it.
• AlphaCode then identifies the semantic duplicates: programs that look different but give the same results on all the tests.
• AlphaCode selects one instance each out of ten clusters of semantic duplicates, starting with the largest, and tries to “submit” them as solutions; if one of them is accepted, the problem is considered “solved.”
• AlphaCode’s performance relies on a certain formulaic manner of programming contests and the presence of repetitive motives in the field.
