Its embedded operating system, based on a PC structure, is attached to a digital signal processing unit (DSP) and dual-channel microphone signal conditioning electronics to form a fully integrated platform, flexible to use, dedicated to several types of real-time acoustic analysis.
Although ChainForge supported this functionality before via prompt chaining, it was not straightforward and required an additional chain to a code evaluator node for postprocessing. You can now connect the output of the scorer directly to a Vis Node to plot outputs. For instance, here's GPT-4 scoring whether different LLM responses apologized for a mistake:
Note that LLM scores are finicky --if one score isn't in the right format (true/false), visualization nodes won't work properly, because they'll think the outputs are notof boolean type but categorical. We'll work on improving this, but, for now, enjoy LLM scorers!
We thought long and hard about what to call LLMs that score outputs of other LLMs. Ultimately, using LLMs to score outputs is helpful, and can save time when it's hard to write code to achieve the same effect. However, LLMs are imperfect. Although the AI community currently uses the term 'LLM evaluator,' we ultimately decided not to use that term, for a few reasons: 1. LLM scores should not be blindly trusted. They are helpful if you already have a sense of what you're looking for, and want to grade hundreds of responses and don't care about picture-perfect accuracy. This is especially true after playing with LLM scorer nodes for a while and finding that small tweaks to the scoring prompt can result in vast differences in results. 2. Evaluators, like 'graders' or 'annotations,' is a term that has connotations with humans (i.e. human evaluator). We want to avoid anthropomorphizing LLMs, which contributes to peoples' over-trust in them. 'Scorers' still has human connotations, but arguably less so, and less authoritative ones than 'evaluator'. 3. Evaluators is a term in ChainForge that refers to programs that score responses. Calling LLM scorers 'evaluators' loosely equates them with programmatic evaluators, suggesting they carry the same authority. Although code can be wrong or incorrect, the scoring process for code is inspectable and auditable --not so with LLMs.
Thousands of lines of Python code, comprising nearly the entire backend, has been rewritten in TypeScript. The mechanism for generating prompt permutations, querying LLMs and cache'ing responses is performed now in the front-end (entirely in the browser). Tests were added in jest to ensure the outputs of the TypeScript functions performed the same as their original Python versions. There are additional performance and maintainability benefits to adding static type checking. We've also added ample docstrings, which should help devs looking to get involved.
When you are running ChainForge on localhost, you can still use Python evaluator nodes, which will execute on your local Flask server (the Python backend) as before. JavaScript evaluators run entirely in the browser (specifically, eval sandboxed inside an iframe).
This study has several limitations. First, Google data are only generated by Android users who have location services switched on. These individuals may be an atypical minority of the population in some countries, or there may be changes in the type of users over time, such as tourists (as in Greece), although in most cases the impact will be small. Second, Google only published data from early 2020 and, as mobility is seasonal, it would have been preferable to have used the same week in previous years as baseline. Third, the number of cases is influenced by the availability of testing and quality of reporting. Fourth, the use of an ecological design introduces scope for confounding and imprecision: our data do not allow us to isolate the impact of mobility restrictions from the many other variables that intervene in a pandemic response, such as the degree of inter-household mixing, the ability to detect and rapidly control an outbreak, and behavioral characteristics such as use of face coverings and adherence to physical distancing guidelines, themselves influenced by clarity of messaging and trust in official advice. A related limitation is that, in large and, especially, federal countries such as the United States, there may be substantial sub-national differences in implementation of these characteristics and in other policies. However, given the complex nature of these relationships, influenced by starting conditions, feedback loops, and non-linear relationships, the analytic challenges of disentangling these factors are formidable even if data were available.
