From the abstract

Conversational modeling is an important task in natural language understanding and machine intelligence. Although previous approaches exist, they are often restricted to specific domains (e.g., booking an airline ticket) and require hand-crafted rules. In this paper, we present a simple approach for this task which uses the recently proposed sequence to sequence framework. Our model converses by predicting the next sentence given the previous sentence or sentences in a conversation. The strength of our model is that it can be trained end-to-end and thus requires much fewer hand-crafted rules. We find that this straightforward model can generate simple conversations given a large conversational training dataset. Our preliminary results suggest that, despite optimizing the wrong objective function, the model is able to converse well. It is able extract knowledge from both a domain specific dataset, and from a large, noisy, and general domain dataset of movie subtitles. On a domain-specific IT helpdesk dataset, the model can find a solution to a technical problem via conversations. On a noisy open-domain movie transcript dataset, the model can perform simple forms of common sense reasoning. As expected, we also find that the lack of consistency is a common failure mode of our model.

Read this paper from July of last year and it'll make more sense as to why this research is interesting: http://arxiv.org/pdf/1506.05869.pdf. Seeding a dataset with human labels, then generating new, better data is pretty cool. Similar to deep mind watching go games, then learning to play better than said games. Add to which, humans can't tell the difference between the human generated data and algo generated data. We're about 3 months from where you can bootstrap a system like microsofts with freely available code and data. From there, if "memory modules" start working better so models can "remember specific context" (it can already remember general context), you'll have a bot that's a pretty good model for passing the Turing test. I'm defining a practical Turing test as text-based, human gets 5 questions, other party replies 5 times, then human must predict: human/not human.

My personal "oh shit" moment was in 2015, when this paper came out: https://arxiv.org/abs/1506.05869 It showed me that a model trained only on movie subtitles data exhibited some (very primitive) reasoning. I have been working on Deep Learning and later LLMs ever since.

Exactly, because it has a shot. Writing that it doesn't have a chance is just effect of lack of knowledge in ML field. You can see some work that was already done in this research paper, before AlphaGo success. http://arxiv.org/pdf/1506.05869v1.pdf

It seems like an old way to solve the problem. I would be quite surprised if it gave good results compared to recent advances such as the LSTM-based paper “A Neural Conversational Model” [0]. In fact, I doubt it is even competitive compared to Cleverbot. It does try to compare itself with existing alternatives, but it does not characterize the pros and cons of each alternative and does not compare results. (I am not an expert, but did take classes on the subject of pattern recognition and machine learning.) [0]: http://arxiv.org/pdf/1506.05869v1.pdf

> If this is the state of the art in machine translation, how on Earth can you expect a machine that can converse on human level in three years? Here are 2 good papers--one from last year, one very recent--that might change your mind. https://arxiv.org/pdf/1506.05869.pdf https://arxiv.org/pdf/1605.06065v1.pdf Over the past 10 years (deep learning got going in ~2006, really), the state of the art has improved at an exponential rate, and that's not slowing down. There are plenty of reasons to be bullish. Or at least, now seems like a bad time to leave the field.

Simulating bad typing is only necessary to fake a human. Here, having bad typing when faking an AI is stranger. That said, AIs trained through the chat transcripts of a large number of conversations may produce mistakes. I remember reading a paper that gave good results that way, with the side-effect that it produces typing mistakes as a result. I cannot find that paper again, unfortunately. Edit: found it! http://arxiv.org/pdf/1506.05869v1.pdf

Talent vs Luck: the role of randomness in success and failure

A. Pluchino. A. E. Biondo, A. Rapisarda

The largely dominant meritocratic paradigm of highly competitive Western cultures is rooted on the belief that success is due mainly, if not exclusively, to personal qualities such as talent, intelligence, skills, efforts or risk taking.
